Visual navigation over LAND was NOT an exact art (it pretty much is now with Global Pos Sats). I have several times found myself blown off course on a short flight of maybe 250 miles (and I can see what's under me when flying over the ground). (I have completely missed an Island offshore due to fog.) The problem is, the further you fly on a given heading, the harder it is to stay on course and the bigger any error will be.

Verification that the bottom antenna was ripped off is, obviously, a critical fact relating to the Earhart mystery. One which no one else has uncovered. And one which may have a direct impact on why the communications failed so miserably. There has been so much speculation about this and maybe it comes down to something as simple as a lost antenna. As I recall we were never able to resolve exactly what radio gear was hooked up to which antenna. I suggest someone contact Elgin Long re the antenna hook ups. He seemed to have fairly strong documented info on the radio set ups and modifications. I was going to ask him about the antenna connections when he gave his presentation in Oakland, but didn't get to. He is giving presentations in San Diego and Seattle air museums over the next few months if someone wants to try to catch him then. Good diligent, thorough, documented, and successful investigation in the TIGHAR way. Kudos. blue skies, -jerry PS - if you still need a photo of the top of an Electra I can take a picture of the Lockheed in Oakland. ************************************************************************** From Ric At your convenience, yes, we still need a good close shot of the seam that runs down the middle of the ship. Elgen Long's "knowledge" of the aircraft's radio set up suffers from the same problems that plague the rest of his research. He just doesn't understand the difference between anecdote and hard evidence. He "knows" all sorts of things that he has decided are true and are therefore (to him) true. For example, he is certain that there was a Bendix RA-1 receiver aboard the airplane although there is no real evidence for that. He presents a photo which he says shows the remote head for the RA-1 installed in the cockpit of NR16020 and states that this photo was taken on or about May 26, 1937 in Miami by Pan American mechanic F. Ralph Silas. His source for this information is his own interview with Silas in 1977, forty years after the event in question. There is nothing in the photo itself to date when it was taken or even confirm that it is Earhart's airplane. The remote head is mounted in what seems to be a rather dangerous position on the cockpit's left "eyebrow" panel and sticks down beside the pilot's left temple. Elgen says that this could be very hazardous in the event of a ditching (as indeed it would be) but he doesn't explain while this prominent feature is not visible in any of the many photos taken of the airplane during the world flight. If Elgen has real evidence about the aircraft's radio system he hasn't made it public.

This post contains no Amelia Earhart related material whatsoever. However, since part of the wider TIGHAR mandate is to promote preservation of historic aviation artifacts, I'm hoping that Ric will indulge me for just a moment... The USS Cabot (CVL-28), is the last surviving light carrier from WWII and the only aircraft carrier that retains its basic 1940s era configuration (complete with straight, wooden flight deck). She served with distinction through 18 months of the Pacific Campaign, earning 9 battle stars and the Presidential Unit Citation. During that time, the ship lost 110 members of her crew - 35 as the result of two simultaneous Kamikaze strikes. The Cabot is now at scrapyard in Brownsville, Texas awaiting her fate. To me, learning that this ship still exists was like hearing that Bob Ballard had gone looking for the Yorktown and discovered it...STILL AFLOAT. There is an organization with a chance to save the Cabot as a museum/memprial, but they need help to bring enough pressure on the scrap dealers to sell her at a fair price. I naturally thought of contacting the Earhart Forum, the quickest way to access a large group of highly motivated, history-minded, well-educated, cybersavvy (not to mention good-looking) go-getters and hopefully set them to the task at hand. If anyone is interested in learning more, you can visit the Cabot website at << www.usscabot.com >> or contact me directly.

In the 12 years we've > been working on Earhart case I've been continually amazed at how difficult it > is to make a dent in the legend. It's been quite an education. The public is usually ignorant about history in any case. The obvious route is to get the source material and accounts of it into data bases and repositories that are likely to be protected and consulted through the centuries. Thus, truth will have a way of slipping through, regardless of the wider motives of the writers of history. The average person has difficulty retaining complex and seemingly conflicting ideas simultaneously. This is probably partly due to human nature, and certainly something that better educational methods could alleviate. But progress along these lines is very slow-- it has taken 5,000 years (since the invention of writing) to gradually pull people from living in a soup of superstition and ritual into a cauldron mixed with superstition, ritual, and a few basic points of reality (no need to digress here into the enormous survival benefits of blind ritual-- which is a kind of cultural instinct). Romantic subjects are notoriously prone to distortion, and people often accept fictional novels and short stories tied to historical events as fact. Be patient, protect and disseminate TIGAHR's discoveries and excellent documentation. Over time (and it could be a very long time), widely published historians will tend to pick up elements of the TIGHAR thread. Even if TIGAR finds something like a chunk of engine block on Niku with an Earhart related serial number on it, it could be years (even decades) before wide public acceptance happens. And if acceptance comes quickly (spectacular news coverage, etc), the accompanying distortions from bad Hollywood movies and intellectual adventurers trying to grab attention will utterly vex you anyway! regards, william 2243 ========================================================================= Date: Wed, 1 Dec 1999 19:43:33 EST From: Herman De Wulf Subject: Re: off-topic details Bill wrote: << We conjecture that AE & FN weren't where they thought they were since > Judging from own experience I think it is safe to say that when a pilot knows exactly where he is, he'll find whatever it is he's looking for. It's basic navigation. But AE's radio message tells us : "We are on you". But they couldn't see it. Therefore I think we must assume they were not where they thought they were, probably X miles off, perhaps indeed as little as 10 miles as has been suggested here. But that is exactly the problem. And that is what TIGHAR (and others) have been trying to solve for the last 60+ years. They were clearly not where they thought they were. And I think they didn't have a clue as to where to look. If their navigation told them they were x miles from Howland, as Bill says, an d if they were sure of that, then it would have been a piece of cake heading for Howland. They didn't, and one reason why is that visibility was not what we believe it was, as I tried to explain in my previous posting. It is generally believed that the weather was clear. How clear exactly ? Was Howland CAVOK ? If so that would imply 10km visibility. If Itasca could see the horizon, visibility would have been something like 20 miles. If it was less, not seeing Howland is understandable. And finding Howland in that vast empty ocean without radio aid not only called an LOP but for "GPS quality" navigation by Noonan. It also called for better than CAVOK visibility for a VMC approach.Do we have information on visibility at or near Howland that day ? Put simply : did the Itasca crew ever mention they could see the horizon ? If they did and AE was flying at 1,000 ft.as has been said, then FN had a problem. If they didn't, they still had a problem but at least we know which one. LTM from Herman, who used to find pins in haystacks, weather permitting ************************************************************************** From Ric Throughout the morning of July 2nd the ITSACA's deck log recorded visibility "9" which means "Prominent objects visible above 20 miles."

Yes, what appears to be a cap on the object in MAY20DEP.JPG is small. It would cover a stopper and bottle neck about the size you find in the typical Thermos bottle when you remove the larger "drinking cup" type cap.

Hmmmm" Yep. This is a good example of how careful you have to be about interpreting historical sources, and avoiding reading things into them. From Maude's standpoint, given what Maude was interested in, I imagine they DID survey the island "thoroughly." They looked it over for possible places where people could live, looked at its coconuts, generally checked out its agricultural land, got a sense of the productivity of the lagoon, etc. He wasn't being slipshod, or saying anything untrue, when he said they had "thoroughly" inspected the place; they just weren't inspecting it to find airplanes or aviators. In the same sense, the TIGHAR crew this year "thoroughly" inspected a portion of western Nutiran looking for airplanes and aviators, but it would be wrong for somebody interested in, say, spider populations to surmise that TIGHAR did a thorough arachnid survey.

Basically we were trying to understand why AE and FN failed to find Howland, I guess.... OK, so FN either unknowingly made a minor navigation error and they missed Howland, or his calculations were correct, as Bill thinks, and they knew where they were but they didn't find it. The mystery remains. LTM from Herman (who for a moment thought poor visibility was to blame). ************************************************************************* From Ric From what I've seen of the case it seems to me that Earhart and Noonan failed to find Howland because an essential element in their navigational plan failed. That essential element was navigational assistance via radio. That assistance could have come in the form of instructions (what we today would call "vectors") from the Itasca based upon bearing taken by the ship, or from bearing taken on the ship by the aircraft's own DF equipment. There is no evidence I know of to indicate that Noonan ever expected to find Howland by DR and celestial techniques alone. The radio was an essential part of the equation. At least part (and we're not sure just what part) of the radio failure was caused by the takeoff accident that deprived the airplane of its belly antenna. Whatever it's purpose, we can be quite sure that it had a purpose, and that it's loss had serious consequences. The knowledge that the aircraft suffered from such an accident adds an entirely new dimension to the Earhart disappearance which, in the past, has been laid entirely to human error.

I'm new to the forum and I (and I suspect other newbies) would love to get some facts together in a line, so to speak. I have read the FAQ list but there is SO much information there that it overlaps itself. Anyway, to get to the point --- I would like to ascertain if the following items are why Tighar believes that AE and FN had landed (or crashed?) on Niku. Physical evidence: 1. A fragment of a woman's shoe that might have been worn by Amelia 2. A bottle of Benedictine that might have been Amelia's or Fred's. 3. A sextant box that might have belonged to F. N. 4. Some bones that could be Amelia's or Fred's 5. A photo of "something" on the reef that is currently being analyzed to see if it might be wreckage from the Electra. Anecdotal "evidence" 1. A woman named Emily's story that she saw some "airplane wreckage on the reef." when she was living on Niku. I understand that each or any of these things could be elaborated on but are they essential the point? Inquiring minds, etc.. ... Regards, Jim Razzi *************************************************************************** From Ric It's bit more involved than that. Here's a quick summary: 1. We are aware of no evidence that suggests that the flight went down at sea. No radio call was heard announcing such a ditching nor did Earhart ever say that fuel exhaustion was imminent. The 1937 search failed to find any trace of debris on the sea. (Itasca Radio Log. U.S. Navy Search Report) 2. When last heard from at 08:43 Earhart said she was flying on a "157/337" line but she was not understood to say what direction she was flying on that line. (Itasca Radio Log) 3. Such a line passing through Howland Island also passes within visual range of Gardner island. 4. Our fuel calculations indicate that the flight, when last heard from, had adequate fuel so that if Earhart followed the line in the 157 direction she should have reached Gardner. (Chater Report. Kelly Johnson tlegrams.) 5. The Navy's July 9th aerial search of Gardner noted signs of recent habitation which are not readily explainable unless they were left by the people who disappeared in that area one week before. (Lambrecht's report.) 6. The British October 1937 visit to Gardner noted signs of previous habitation which are not readily explainable unless they were left by the people who disappeared in that area three months before. (Bevington's diary) 7. Early settlers on Gardner Island (Nikumaroro) tell of an airplane wreck on the reef in 1940, long before any possibility of WWII activity. (Interviews with Emily Sikuli and Otiria O'Brian in Fiji in 1999.) 8. A wartime anecdotal account describes aircraft debris in use by residents of Nikumaroro in 1944 which the locals said came from "an airplane that was here when our people first came." (Interview with former USN PBY pilot Dr. John Mims in 1995.) 9. Photographic evidence confirms the presence of anomalous material on the reef in the location where aircraft wreckage is described to have been seen. (1937 Bevington photo, 1938 NZ survey photos) 10. Anecdotal accounts of former residents describe aircraft debris seen on the reef near the main lagoon passage, in the shoreline vegetaition, and along the lagoon shore just opposite the passage in the late 1950s. (Interviews with Pulekai Songivalu and Tapania Taeke on Funafuti in 1997) 11. Photographic evidence indicates the presence of light colored metal debris on the reef-flat near the main lagoon passage in 1953. (Forensic imaging of 1953 aerial mapping photo.) 12. Aircraft debris consistent with the Lockheed Model 10 and (to date) not identified as consistent with any other aircraft type ever know or suspected to have been in the region has been found in the abandoned village on the island. (Results of TIGHAR expeditions in 1989, 1991, and 1996.) 13. Anecdotal accounts by former residents and an American serviceman tell of the remains of a man and a woman discovered on the island and, in some cases, associated with the purported airplane wreck (Interviews with Dr. Teinamati Mereki and Reverend Aberaam Abera in the Solomon Islands in 1995; correspondence with Bauro Tikana in Tarawa in 1991; interviews with Tapania Taeke on Funafuti in 1997; interviews with Emily Sikuli and Otiria O'Brian in Fiji in 1999; San Diego Union interview with Coast Guard veteran Floyd Kilts in 1960.) 14. Extensive official British government records confirm the discovery in 1940 of the human remains of a castaway who perished while attempting to survive on Nikumaroro sometime prior to the island's settlement in 1939. With the bones were found a sextant box bearing a stencilled number that is similar to a number written on a sextant box known to have belonged to Fred Noonan, and the remains of a woman's shoe and a man's shoe. (Records of the Western Pacific High Commission) 15. Evaluation of the measurements taken of the bones found on Nikumaroro in 1940 by modern forensic anthropologists indicate that the individual was most likely a white female of northern European extraction who stood approximately 5 feet, 7 inches tall. (Paper prepared by Dr. Karen Ramey Burns, Dr. Richard Jantz, and Dr. Thomas F. King for the annual meeting of the American Anthropoligical Association in 1998.) 16. The remains of a shoe found on Nikumaroro by TIGHAR in 1991, in the same part of the island where tradition holds that the bones were found in 1940, has been judged to be of the same vintage, style and size as the shoes worn by Earhart on her final flight. (Analysis by the BiltRite Corporation in 1992.) I've probably missed some points of evidence. There are getting to be rather a lot of them. LTM, Ric ========================================================================= Date: Thu, 2 Dec 1999 19:41:17 EST From: Birch Matthews Subject: human error Please don't forget that Amelia attempted to run a check on her DF while at Lae. She was unable to do so attributing the failure to being too close to the Lae radio station. If DF was so important to Noonan's navigation plans, Earhart should never have taken off for Howland without positive confirmation that her system was working, and that she was proficient in its use. In that context there was definitely human error on the part of both parties. ************************************************************************** From Ric I suppose we can't say for sure whether the DF was working during the test flight or not. Perhaps Amelia was right, but it does seem negligent for her not to have gotten a positive check on it. It also seems negligent for neither her nor Nonan to have been proficient in Morse or to have insisted upon better coordination with the Coast Guard. If Lindbergh had failed to reach Paris I wonder how many instances of negligence we'd be able to come up with.

LTM, Ric ========================================================================= Date: Fri, 3 Dec 1999 09:53:13 EST From: Birch Matthews Subject: Fuel Exhaustion Descent In context with the absence of any Mayday from Amelia at to point of fuel exhaustion, consider that she was probably still flying at 1,000 feet when the tanks ran dry. (To have climbed higher again would have depleted her fuel supply at an even greater rate.) She would not know precisely when the fuel would be exhausted, only that she was extremely low on fuel with each passing minute. Certainly she must have been simultaneously still searching for any safe haven to set down. One can imagine she would have been rather busy at the moment the last drop of fuel passed through the engines. She would have been trying to extend her glide and then set up for a crash landing while working the wobble pump in a vain attempt to coax a bit more fuel into the engines. Unless Noonan was up front too, it would have been difficult to find time to send a last message. At a rate of descent of 100 ft/min, she would be at sea level in only 10 minutes from the point at which the airplane started down. At a downward rate of 150 ft/min, the descent would have been about 6.7 minutes. At 200 ft/minute she had only 5 minutes to do anything. Not much time. There is also the likely possibility that at some point she stalled the airplane trying to stretch her glide path. This could easily reduce the time values mentioned above. I don't know what the power-off sink rate of the Model 10 was, but I doubt it was less than 100 ft/min. Superimpose fear and fatigue on this situation and I find it entirely plausible that no Mayday message went out over the airways. I also understand that this is speculation on my part, but I would argue at the same time that it is not an unreasonable scenario. ************************************************************************* From Ric And I woud argue that to speculate that Earhart permitted the tanks to run dry in flight is to: 1. Make the assumption that she and Noonan were unsuccessful in their attempt to find land. 2. Make the assumption that Earhart was either unaware or chose to ignore the fact that her chances for survival in a water landing would be greatly increased by deciding to execute a ditching under power rather than wait until the engines failed. Speculation about why Earhart did not make a distress call is no different from speculation about why the Navy's aerial search of Gardner did not see the airplane on the reef. Each is an aspect of the hypothetical scenario that doesn't seem to make sense so we try to think of possible explanations. In the case of the crashed-at-sea scenario, the cessation of radio transmissions is the only indicator that the flight may have ended that way. To make it work one must argue, as you have, for the crew's incompetence. In the Nikumaroro scenario there are abundant indicators that the flight did reach the island and there is no need to ascribe to the crew any unprofessional behavior.

In the wake of the shocking news that the aviators were missing, a rumor arose in France that the American weather bureau had intentionally withheld word of a storm over the Atlantic to lure the French heros to their death. Things got pretty ugly in the streets of Paris. Some American flags got burned and Ambassador Herrick urged American contenders for the Orteig Prize not to take off for a few days.

For example, are the things we consider poorly done or negligent today, applicable to the standards in effect then? Some things, of course, are unchanged since Orville and Wilbur. However, I have the impression we now have a more highly developed sense of aviation professionalism Vs aviation "foolishism." This does not denigrate yesterday's aviators, it's just the nature of maturation. So, should historic figures be evaluated against the standards of their times, or, current standards, through the looking glass of comfortable perspective? (Thomas Jefferson --though not an aviator so far as I know-- is a good example of this "applicable standards" conundrum.) Thanks. E.G. Kindley, 2131 ************************************************************************** From Ric Excellent point. If historians, and especially historical investigators, had a mantra it would be "Context. Context. Context." Today we have much, much higher expectations of safety and security than were prevalent in the 1930s (heck, we put helmets on kids on tricycles!). Earhart wrecked at least 11 eleven airplanes in the course of her career. She and Noonan flew around the world in an uninsured airplane. They never filed a flight plan because there was no such thing as a flight plan (in any formailzed sense). To get some sense of the mix of pioneering bravado and budding professionalism that pervaded 1930s avaition I would urge anyone to visit a good library and leaf through the aviation periodicals of the day. It was a different world. ========================================================================= Date: Fri, 3 Dec 1999 10:53:44 EST From: Jim Razzi Subject: Re: Facts of the case Thanks for the extensive summary and I think many other newcomers will appreciate it also.

There surely were a number of people who witnessed the little mishap when the Electra was lumbering along the ground, so wouldn't they investigate the area to see if, in fact, something HAD been dislodged from the plane? Regards, Jim Razzi ************************************************************************** From Ric The most likley time for the ground strike to have occurred was during the turn around at the far "approach" end of the runway which was easily half a mile from where the spectators stood. This is when the aft antenna mast was at risk from sideloads for which it was not stressed. We do have one second-hand anecdotal account which indicates that the antenna was later found on the runway. Bob Fullenwider, TIGHAR 0126, says that while he was stationed in Lae during World War II an "old timer" who had worked at the airfield before the war told him that he wasn't a bit surprised when Earhart went missing because "we found her antenna wire laying on the runway after she left." Bob related this anecdote long before we had established that the antenna was missing in the photos. If such a discovery did take place, neither Collopy nor Chater was apparently aware of it when they wrote their respective reports a few weeks later.

McGee #0149CE ************************************************************************** From Ric Now, mind you, I've never done this and I hope I never have to, but this is what I've read about ditching and it makes a lot of sense. So there you are, faced with the prospect of putting a land airplane down in the open ocean. Your "runway" is not going to be flat. If you're lucky it will be a series of rolling hills (swells) and valleys (troughs) which may or may not be aligned with the wind. At the speed you're going to hit them (in an Electra, roughly 60 mph) they're made of concrete, so it makes sense not to smack into them but to land along their long axis on the "back" of a swell, even if it means a crosswind approach. You also don't want to make a three-point full stall arrival. Much better to come in nose-high and drag your tail before you hit. You're almost certainly going to skip once before the nose digs in and you come to an abrupt stop, so the slower you can be going the better. You might even come in below your power-off stall speed "behind the power curve" with full flaps and carrying quite a bit of power. It's a hairy prospect and it might take several tries to get everything lined up just right, but if you sit up there trying avoid the inevitable until the engines quit you're going to be faced with taking whatever you can get - dead stick and out of options.

Good point. At the other hand, Frenchmen Nungesser and Colli failed to cross the Atlantic (flying west) only two weeks before Lindbergh succeeded (flying east). Nobody accused them of anything, certainly not of negligence. They simply ran out of luck. In 1927 people believed aviation was not yet ready for that kind of exploits. The crossings by US Navy Commander Read in hops via the A=E7ores and Lisbon in a Curtiss NC-4 proved the crossing was hazardoud. And the other succesful crossing that year by Brits Alcock and Whitten-Brown in a modified Vickers Vimy bomber in May 1919 won them the Orteig prize for the first crossing but had proved only that airplanes could fly from New Foundland to Ireland. Both flights had been such hazardous achievements that by 1927 it was generally believed aircraft were insufficiently reliable to link continents. Lindbergh proved them wrong, thanks to his dependable Wright Whirlwind engine and the big fuel tanks of his Ryan NYP. And being extremely lucky for not icing-up and waking up in time before crashing into the ocean. Having flown non-stop from New York to Paris he was the first to link the continents by air and became an instant hero. Nungesser and Colli, who almost succeeded, were soon forgotten. They were not blamed for enaything. They probably iced-up and crashed, either in Canada or in Canadian waters, having succesfully crossed the Atlantic. We'll never know for suere as long as their airplane hasn't been found. Being made of wood and canvas there is little chance anything of it can still be found. As with AE/FN indications are they almost reached their destination, their ultimate fate remaining unknown. The "indications" are basically Canadians declaring having heard an airplane around the time Nungesser and Colli could be expected to be in that area. >Earhart was female and famous, which for good and bad is also a great >recipe for public fascination. Correct. Isn't that why we are still trying to find out what happened at Howland and Gardner ?

With two props windmilling that pig would probably glide like a toolbox - and AE probably knew it. On top of that, the big engines of the 10E tended to make it noseheavy. The 10E that ditched off Massachusetts in 1967 lost power in the right engine and the pilot couldn't maintain altitude with the left engine operating (that's how bad it is if you don't have full-feathering props). He made a successful ditching but the water was calm near the shore and he still had the left engine. To say that AE waited until the engines quit to land the airplane (whether on land or water) is to call her an idiot.

I did not imply, nor should you infer from my comments, that I presume to know where the airplane came down. I do not. When I noted: "At a rate of descent of 100 ft/min, she would be at sea level in only 10 minutes . . ." the use of the words sea level is an altitude reference, not a spatial location. I deliberately chose my words carefully to encompass the Gardner Island possibility. The intent was merely to illustrate that from 1,000 feet, it doesn't take much time to reach the earth, and that this fact alone may account for the lack of any Mayday. I don't claim that's what happened, only that it is a rational scenario. In response to your first comment, I did not "make the assumption that Earhart and Noonan were unsuccessful in their attempt to find land." To the contrary. My scenario includes this possibility. With respect to your second response, aircraft ditching at sea was, I believe, not widely studied until the advent of World War II. I have not seen any reference indicating Amelia was trained or studied the art of ditching an airplane with or without power. If she was in proximity to Gardner Island, you may be entirely correct in your speculation. And finally, please tell me specifically how you reached the conclusion that I have argued on the side of crew incompetence or unprofessional behavior? That is a pretty harsh retort in view of the fact I was merely attempting to give some perspective of how little time it takes to descend 1,000 feet. *************************************************************************** From Ric I'm sorry if I responded too harshly. You began your posting with: "In context with the absence of any Mayday from Amelia at to point of fuel exhaustion, consider that she was probably still flying at 1,000 feet when the tanks ran dry." That seems pretty clearly to make the assumption that the tanks ran dry. My point was that it would have been foolish ( incompetent, unprofessional ) for her to allow the tanks to run dry. Subsequent postings have made the case that the descent, in such asn event, could well have been considerably more rapid than you postulated. In other words, there is a consensus that you are correct in saying that an inflight dual engine failure at 1,000 feet would make things pretty exciting in the cockpit and might preclude a distress call, but (and for that very reason) there is also a consensus that such a scenario is less likely than a landing under power. While it is certainly true that ditching procedures became formalized and much more widely disseminated during WWII, the notion that it is better to make a precautionary landing with power than to wait until you run out of gas probably goes back to the Wright brothers. Amelia herself exercised that option on numerous occasions and thoughout her career as a long-distance flyer I'm aware of no instance in which she ran out of gas in flight.

Earhart and F. Noonan loading NR16020 depicted in the photograph taken by Dustin Carter at Burbank Airport on May 20, 1937 (may20dep.jpg). This letter addresses the relationship between 2-4-V-100 and the rightmost canister-like object located in a group of four canister-like objects located on the ground to the right of A. Earhart's feet. While the JPEG image may20dep.jpg shows this canister-like object to be overexposed, the original negative is properly exposed. Several structures present in 2-4-V-100 are absent in the canister-like object in may20dep.jpg. These are: 1) 6 metal bands that wrap around 2-4-V-100, and 2) what appears to be a handle located at the top of 2-4-V-100. Further, 2-4-V-100 has a transition area from its neck to its body that is flatter (has a smaller angle relative to vertical) than that shown in the canister-like object of may20dep.jpg. This difference cannot be due to damage to 2-4-V-100 because the required deformation would not result in the smooth surface seen in this part of 2-4-V-100. While there are additional differences between 2-4-V-100 and the canister-like object of may20dep.jpg, these reasons are sufficient to establish that these are different objects. Therefore 2-4-V-100 does not match the canister-like object seen in may20dep.jpg. Best Regards, Jeff Glickman Board Certified Forensic Examiner Fellow, American College of Forensic Examiners Jeff Glickman PHOTEK 209 Oak Avenue, Suite 202 Hood River, Oregon 97031 ************************************************* I had a couple of questions for Jeff, to whit: There are no metal bands that wrap around the artifact. Those are impressions stamped into the metal. The body of the cannister is a single sheet of metal. I can see one "ring" around the object in the May 20 photo but it does seem to be a slightly different distance from the top of the cannister than is a similar "ring" on the artifact. The handle on the artifact rotates freely and we had speculated that a similar handle on the cannister in the May 20 photo might be oriented edgewise to the camera. The differences in the transition area from the neck to the body do, however, seem to be a disqualifier. Ric **************************************************************************TTo which Jeff replied: Ric, Here are clarifications to your questions: By "metal bands" I also mean "impressions stamped into the metal". I did not mean to imply that sole source of the metal bands could be seperate pieces of metal applied to the body of the canister, but rather they are visual features present on the canister. may20dep.jpg has a circular top, possibly a cap, composed of a polished metal containing a complex reflection. It is the reflection of adjacent items in the circular cap which gives the mistaken impression of a handle. Best Regards, Jeff Glickman Board Certified Forensic Examiner Fellow, American College of Forensic Examiners PHOTEK 209 Oak Avenue, Suite 202 Hood River, Oregon 97031 *************************************************************************** Okay. So 2-4-V-100 is not the thing in the May 20 photo. That doesn't mean that it's not Amelia's fire extinguisher but it does mean that the photo is not a reason to think that it might be.

And five minutes is a very long time when you experience an emergency of any type. This is a comment from actual in-flight emergency experiences in various antique aircraft. Just sit and watch the clock for five minutes and you will see what I mean. The human mind works very fast and the model 10 was a good flying aircraft so the demands on a pilot, in my most humble opinion, would not have been such that it would have prevented a radio call. Although this opinion is offered, it just illustrates the fact that there is no black and white answers for now except that they didn't make it. Ty N. Sundstrom *************************************************************************** From Ric The fuel system schematic for NR16020 does seem to indicate that both engines always fed off the same tank - a bit weird but it does simplify fuel management. However, as you say, other factors make a truly simultaneous silence be pretty unusual. As for the way time goes into slow motion in an emergency: I couldn't agree more. I'm sure we all have our own stories ========================================================================= Date: Fri, 3 Dec 1999 18:54:14 EST From: Ross Devitt Subject: Re: Fuel Exhaustion Descent If Amelia Earhart was at 1000ft and IF the engines failed at that height, she would not have descended at 100 or 150 ft per minute. The aircraft is just too heavy to sustain that rate of descent without power. Ask anyone who has been practicing forced landings in a Cessna or Piper what their R.O.D. is in a glide... I gather Ric is/was a pilot (I think I read it somewhere). Anyway there must be lots of other pilots on this forum. Rate of descent is controlled by power, you add power you go down slower. Without power, you have to actually get the nose DOWN to keep flying. I haven't seen the Electra's flight manual, but I doubt it would glide better than say a modern Beech Baron (twin) and remember they were supposedly carrying a lot of freight (spares). I believe they would not have had more than 2 minutes to descent in glide configuration from 1000ft. What gets me is "KHAQQ CLNG ITASCA WE MUST ON ON YOU BUT CANNOT SEE U" - At 1000feet, if Earhart was say 30 or 40 miles off track or had somehow overflown Itasca at that time, she would be unlikely to see Gardner Island or Itasca. All it would take was for the sun to be low, or a little haze... We know from her reports at this time she still had at least an hour of fuel. "BUT GAS IS RUNNING LOW BEEN UNABLE TO REACH YOU BY RADIO WE ARE FLYING AT A 1000 FEET 42" On her frequency - in fact on any frequency - her chances of being picked up by ITASCA were bad. Anyone who flies would tell you, the radio will work better, higher, say 3 or 4 thousand feet. There are only two reasons she would logically descent to 1000ft. 1 Due stress of weather. (She may have encountered low cloud some distance out that was not apparent to ITASCA) - I believe this is most likely (been there, done that). As close as she was to Howland, she would not want to waste fuel climbing again. 2 She may have had some relatively minor engine problems especially if she'd had to lean the mixture excessively. We know there were some plug problems with the type of engine and they had to be changed regularly - For her to remain at 1000ft meant she was pretty certain she was close. I fly around islands in the tropics. I would not attempt to look for a small island from below 3000 feet. From 1000ft a small island might be "just over the horizon" or "just under the aeroplane". It's unlikely the Electra would have a glide descent of better than 500ft per minute. 2 minutes is plenty of time to make a distress call. "Mayday, mayday mayday - KHAQQ, KHAQQ, KHAQQ, out of fuel, on line 157 337, ditching in water" If I say that slowly, and clearly it takes about 15 seconds (try it). There's not a lot more she could have said. Of course if she was a fair distance from ITASCA by the time she supposedly "ran out of fuel", and if they were transmitting at the time she made the call - they would not have heard it. On the other hand, If AE still had her reserve 20% when she arrived near Itasca (and at sig strength 5 she had to be fairly near) she could have given up in frustration and flown to the nearest alternate island. Sorry to "waffle on" but the following points have been bugging me for some time. Why was AE at 1000ft. when she had: Less chance of her radio being effective, Less chance of seeing the island and Less time to plan a descent if something went wrong. Ross (Who had no intention of doing anything but read this stuff) ************************************************************************** From Ric Well Ross, your first guess was correct. The reason was almost certainly weather. ITASCA's deck log described "blue sky with detached clouds" throughout the morning and an observation taken on Howland puts the scattered deck at 2,650 feet. It may well have been a bit lower earlier. Those are very typical conditions out there, and as you know, if you're above even a widely scattered cloud deck you can't see anything except what is right below you. ========================================================================= Date: Fri, 3 Dec 1999 18:58:00 EST From: Dan Postellon Subject: Re: Fire extinguisher Ric wrote: <> I agree.

I don't want to begin another off-topic discussion here. But I think it is useful to remind a number of things have changed since the old days. Ric summed it up very well. You can't just fill'er up, kick the tires and fly to Paris. You have to file a flight plan if you intend to make any international flight and it has to be approved first. Most airspace on this side of the ocean is class B or C today. Airspace is controlled from 4,500 ft up, not uncontrolled up to 18,000ft as in the US. You're watched by radar all the time by the aviation authorities and the military of the countries whose airspace you use. That's why they insist you inform them you're coming. Your aircraft has to be equipped with a number of compulsory instruments, including two-way radio, transponder and ELT. All these things Lindbergh didn't have to bother with. He didn't want radio to save weight... For overwater flights life saving gear is compulsory (lifevests at least and you have to wear them if you're flying a single engine). For international flights you need your private pilot license endorsed for "working knowledge of IFR", after an examination. This is not an IFR qualification, merely a safety safeguard to keep you from flying into hills or ditch in the water in poor visibility while flying VFR abroad. The endorsement is issued by the national civil aviation authorities after an oral and a practical examination about instruments, familiarity with IFR and radio procedures. Radio license is compulsory of course. There's no flying without radio any more. You'll have to prove you're able to fly blind safely for 50 minutes, executing ATC procedures as told, getting your aircraft out of "unusual situations". Generally you have to prove you know the ropes, won't get lost in cloud or fog or crash into a mountain. Before passing the test you have to prove you've had at least 10 hours instrument practice. Just to fly VFR. They won't let you fly the Atlantic, though (it would be foolish to try) if you're not fully IFR qualified. When filing your flight plan you have to stipulate your route, flight level or altitude and provide the list of diversion fields. In France they have you sign a document in which you promise to pay for the cost of looking for you when you ditch and for fishing you out of the drink should you want to make an overwater flight... Suppose you fill up your Cessna 172 and go as Dennis suggests. You cross the Atlantic succesfully (you may need some extra fuel). Well, then you'd have a lot of explaning to do when you land at the other side and you'll lose your license for having entered airspace without permission and probably for having violated all the rules in the book of international flying... Ric, I have no intention of going into the details any further lest this becomes another off-topic discussion. My pint was that if Charles Lindberg and Amelia Earhart were still around and would like to do again what they did in their day and in the same way, they wouldn't be allowed to take off by the authorities because so many rules have been invented since that didn't exist then. And because aircraft have to be equipped in a way their's was not. Most of the equipment that is compulsory now wasn't even invented. And they defenitely wouldn't let Lindbergh leave his radio behind to save weight.

I just became more then a little interested in AE. I'm reading a book intitled 'Flying Blind' a fun bit of fiction written by 'Max Allen Collins'. I was curious about AE's ability as a pilot, was she only 'average' as some have stated?. Was there any truth to the rumor's that AE engaged in some 'biplane' activity? Thanks! John ************************************************************************* From Ric Your question about AE's flying ability is not at all silly but it is difficult to answer and a hotly debated topic. I guess the first step would be to define what constitutes a "good pilot." For me, the standard has always been "Would I let this person take my kids for an airplane ride?" From what I know of Earhart's career and character I would have to say, "No" (but then, I'm rather attached to my kids). I have heard no rumors that she engaged in "biplane" activities (if I correctly interpret that you mean bisexual activity). The only real information we have about her sexual value system is the note she handed Putnam just before the marriage ceremony in which she advised him that she had no intention of remaining faithful to him or vice versa. In any case, such questions have no bearing on our investigation of her disappearance.

That's the entire reference. But I just thought of something. Maybe I'm reading too much into this but I get an implication that the provisions were not just casually left behind but were more or less neatly "placed" in the shelter.>> In order to avoid any 'confusion', I have in the past tried to limit my personal thoughts about Daniel Hamer's statement. However, on this occasion I have to say that whilst I completely understand your caution in analysing his words too closely, I am firmly of the belief that they are accurate, i.e. a true account of events, as he saw them. The way I see it is that whatever the purpose, if he had gone to the trouble of writing those words, then he meant what he said. Therefore, I can only conclude that this was a deliberate act. My father comes from a family in which for the last 2 generations all the men have shared a life at sea, and consequently I have an understanding of such a lifestyle. My opinion is that as Master, Dan would have taken his responsibilities seriously, and if that included an act of good intent, then he would have done it. Such an act would have been an entirely appropriate exercise of his duty. Maybe he did it with the thoughts of those who 'couldn't' be saved, in mind? This too makes complete sense to me. He certainly knew the Steward and his wife personally and the idea that a small, deliberate act could possibly assist anyone in the future, would be an entirely appropriate mark of respect, given that little else was possible. In conclusion, my belief is that if analysis of 'suspected survivors campsite photo' demonstrates that it was 'haphazardly abandoned', then something or someone disturbed it in the intervening years. (The question then being, who or what?) As for the apparent possibility of locating the remains of that campsite sometime in the future......? - fair boggles the mind! Additional Thoughts (Purely THOUGHTS!...) My father suspects that is was highly likely that alcohol could have been included in the 'provisions' sent from Capt. Swindell of the Trongate. (Could this be a source for your Benedictine bottle...??? - Sorry - I'll have to go back and read about that bit again!) Regarding the sextant....... He feels that it would have been extremely unlikely that such a valuable possession, often privately owned, would have been left behind, unless in error. Furthermore, he believes it unlikely that it would have been rescued without it's box. (Am still making enquiries for information relating to the possibility of a connection with Reardon Smiths.) The Rescue Site/The Lee Shore I'm still not sure if I'm clear about this, but are you concluding that this location was to the South (East?) of Bauareke Passage? (I ask only out of interest and not because I have any other view.) That's all, (and I'm sure enough!), for now. Janet ************************************************************************** From Ric Just my opinion, but I think that the Norwich City supply cache is an excellent candidate for the source of the Benedictine bottle as well as the "corks with brass chains" thought to have come from "a small cask." In fact, I think that these possible corelations and the disheveled appearance of the camp in 1938 can be seen as evidence suggesting that the castaway found by Gallagher in 1940 had found and used the Norwich City cache. Obviously, these are not items of hard evidence but they are jigsaw puzzle pieces that happen fit our hypothesis very neatly. My reading of the various descriptions puts the evacuation site somewhere in the neighborhood of Bauareke Passage but it's hard to be more specific than that.

It's a good possibility. Regarding the untidy condition of the cache when it was photographed in 1938, it may be useful to bear in mind that the castaway(s) found by Gallagher were not the only potential customers. Undocumented visitors could have passed through the area in the late 20s and early 30s and gradually, carelessly, picked through the supplies. Storm activity could have also left its mark. A visitor in July 1937 may have found the site already in a state of chaos. william 2243 *************************************************************************** From Ric True. ************************************************************************* From Ross D, And to serve its purpose it (the cache) would have to be somewhere obvious. Is there fresh water in many places on the island? If you were leaving a cache of supplies I imagine you would site it somewhere near water, close enough to the wreck site to carry the supplies and for the wreck to be a reference point. I imagine you would also leave writing implements "just in case". Who knows what you might find. If I pranged an aeroplane on a reef, and assuming my injuries were not too severe, I would drag food, medical kit, flares and rope etc from the aircraft. I would then search for water. If I found a cache of supplies I would make camp close to water and not far from the cache. On the other hand, if I or my partner only just managed to struggle ashore..... I am looking forward to you discovering the cache from NC. A castaway with a Benedictine bottle... Hmmm. I'd say there had to be more goodies where that came from. RossD. (who spilled burning Benedictine on his beard once...) ************************************************************************** From Ric There is no fresh water on the island that can be reached by a castaway, (Later settlers used dynamite to blast wells that produced water of marginal quality.) The only fresh water available to a castway would be what he brought with him, what he found cached on the island, and what fell from the sky in sporadic showers. Finding the NC survivors' campsite is going to be a b--ch. Our only real shot is if we can spot it in the old aerial photos, but the one photo we have of it up close (and we only have that in the form of a photocopy so far) shows it to be back under the trees (naturally).

The Colorado Civil Air Patrol recently spent more than 300 flight hours during the Thanksgiving holiday looking for a Bellanca Viking piloted by a 6000+ hour pilot CFI and his pilot wife, with a brand new hand held GPS, cell phone, etc., who disappeared during beautiful weather without a trace. He did not file a flight plan, and there was no signal from the ELT aboard the plane. The search was unsuccessful even though we had a rough idea of where they disappeared from a position report he made to ATC and NTAP radar return data. Veritable needle in a haystack looking for a green and white aircraft in the pine trees and snow. Just because you have lots of technology in your aircraft doesn't mean that you can't get lost, will get an SOS message off successfully, or assure that you are going to be found. When things go bad they usually go bad quickly, and there is little time to do more than just react to the situation. A cell phone can be useful for the post crash survivors, but establishing credibility these days is just a difficult as it was for the post loss AE messages. We had one crash last January that managed to reach via cell phone the Sheriff's department dispacher who refused to believe that they were the victims of a plane crash, and kept asking if they had witnessed a plane crash instead. After several subsequent calls of unsuccessful attempts to convince the dispachter that they were the victims, their cell phone battery died. If it weren't for the efforts of an intrepid XC skier who heard the plane go down and finally located the wreck after searching for two hours in a blinding blizzard (why they werer flying in the mountains during a blizzard is another question), they would surely have perished due to exposure.

There is a boatload of good information regarding ditching aircraft to be found at: Equipped to Survive http://www.equipped.com/ and in particular a very good case study by a guy who flew from Ohio IFR only to have to ditch in the Chesapeake due to engine failure: Equipped to Survive Ditchings http://www.equipped.com/ditching.htm His research revealed that 63% of ditchings recorded in the NTSB files occured during "non-overwater" flights, much like his own fligt from Ohio. Well worth reading, especially for the pilots in the crowd who think they don't fly over water enough to worry about ditching. Next on the hit parade is a video of a Mooney ditching found at : Rif's Place to Visit http://www.rifkin.com/ scroll down to "Rif's digital photo album" and look for the Mooney ditching video in three different resolutions. Start with the 850K version unless you have a supercomputer with lots of memory and MHZ. In this video you will see quite clearly what Ric described earlier, ie " You're almost certainly going to skip once before the nose digs in and you come to an abrupt stop... " Doesn't look like fun, but in this case survivable. Enough on ditching. Seems to me that since TIGHAR's main theory does not include ditching, and any ditching theory is impossible to prove/disprove until those underwater guys spend the next 100 years searching the Pacific and come up with some hard evidence, we should spend less time talking about something we cannot make any realistic progress on.

Foua Tofinga and Emily Sikuli say that this is where they went off the island in 1941, for what that's worth. LTM TK ************************************************************************ From Ric Here's what we have. Capt. Hamer says in his statement: "The two (rescue) vessels now cruised along the reef in search of a suitable place, the surf near the wreck being far too dangerous. A place was found about 1 1/2 miles south of the wreck, the breakers being not quite so bad, but bad enough to make it anything but a joy ride to get over. We then crossed the lagoon in the boat to where the vessels were waiting on the outside and transported the boat to the edge of the reef." That last phrase is the key. Can you imagine anyone dragging a several hundred pound lifeboat through the scaevola or over the coral rubble rather than walking it through Bauareke Passage? I suspect that Emily and Tofiga left the island from the same place for the same reason. They left in December - Westerly season - so they had to go around to the south side. There had to be a place to get the island surf boat out to the reef. Bauareke Passage is the only game in town.

Since they have that interesting history page on their web site, I hoped they might know what the bottles were like in about 1930. This is the response received: ********************************** Thank you for sending the photo of Amelia Earhart. It is fascinating. I'll try to answer your questions. First, I cannot tell for certain if the pictured bottles are the genuine Thermos brand vacuum bottles. Based on my investigation into our archive product from that era, I believe most, if not all, are Thermos brand bottles, however, I can't be sure. As for the 4th bottle in question, it is also a vacuum bottle. Many bottles of this era had very small cups which, from a distance, look like a simple stopper for the bottle. In fact, the first vacuum bottles had a cork. Then came a more refined stopper and cup. So it was not unusual to see a bottle with a shot glass sized cup/stopper. Thank you again for your interest. John Lanman Vice President of Marketing The Thermos Company ********************************** So... I continue to believe that we are looking at four Thermos, or other make, vacuum bottles. There is no point in tryin to match what we see in that photo with a fire extinguisher. We don't have a picture of the fire extinguishers that were on the Electra. This leaves wide open the possibility that the extinguisher (PYRENE1,JPG) found on Niku is, in fact, from the Electra. It may also have come from the LORAN station, or it may be of some other presently unknown origin. *************************************************************************** From Ric I agree entirely.

I would have thought that with one Yankee buck buying almost $1.50 Canadian right now, it would be a bargain to travel in Canada, and certainly a lot closer than Niku! In the ten years that this project has been on your back burner, what new technology has has cropped up that might help you find the engine? I suppose ground penetrating radar is no good because of the water in the muskeg, but what about ultrasound, or even taking water samples in a grid pattern and then having them analyzed for trace amounts of metallic elements? What about the low-flying-heli- copter-mounted sensors that the USAF was using a few years ago to try and find (unsuccessfully, as it turned out) the missing bombs from that A-10 that the guy used to commit suicide? I thought I'd heard that it was a Canadian invention (the chopper had Canadian registration letters); and heck, that company may even have an office in Newfoundland already! Here's another thought: The Canadian government's Heritage department was able to provide some money ($30,000 Canadian as I recall) to help dig up a Halifax bomber in Belgium a couple of years back, and the results were several proper military burials (the German night fighter pilot responsible was even there all the way from south America!) and many recovered parts to assist in the restoration of another Halifax back in Canada. The entire process was widely publicized here in Canada, especially in aviation circles, and really raised the profile of aviation archeology. My point is that if you've got good evidence to pinpoint where you think the engine will be found, you could very well be able to get some money out of the French government. Perhaps if you lay all your cards on the table for the French Ambassador, you could play to the French sense of pride! Think what a huge find it would be! Mon dieu! Herman was right on the money (Francs or dollars?) about the hoops to jump through for flying the pond. One of my friends living in Ottawa was goofy enough to fly his 172 to London, England and back one summer with his brother. Their planning began many months ahead of time, and they needed all sorts of special equipment on board, especially survival gear (cold-water immersion suits, buoyant ELTs, etc.). Maybe the FAA lets you Yanks gas-n-go, but up here, Transport Canada is a less wild-west minded outfit, and demands that you have a full and current IFR rating, plus you have to get your aircraft inspected and certified by a government official at a certain airport in New Brunswick, before you can even depart. On and on it goes with international paperwork, but I won't bore you with the rest of it all. Basically, although my friend and his bro had the trip of a lifetime, their conclusion was that if you want to cross the Atlantic at far less cost, more easily, faster, and with a much higher margin of safety, take an airliner! By the way, if AE and FN were alive today, AE would be a motivational speaker making the corporate feel-good team-spirit-building weekend-retreat circuit, and FN would be developing GPS software for his own navigational consulting company. They'd probably have met up at some point while she was giving a stress-relief seminar to Fred's overworked outfit. Since both of these characters mesh into the corporate world so well, they'd probably be living at Tokyo addresses now, having been "captured by the Japanese" years earlier. Fred's love of Saki (rice wine) would undoubtably be the subject of great speculation around the office. One last thought, seriously. In concurrence with what others have already postulated, I would be wildly astounded if the gliding rate of descent in the 10E would be any less than 1,000 FPM. Last July, I had an oil-related engine failure in a Cessna 182. It bled out all 11 quarts in the first seven minutes of flight due to an incorrectly installed oil filter - and it was not installed by me! The first sign of trouble was an oil pressure reading of 0, so I shut the engine down and started trimming for best glide speed. Yes, I got the full Mayday out, and was even courtious enough to let the four skydivers on board bail out! Although I was at 4,000 feet AGL when things started to go bad, I was rolling to a stop in a farmer's field less that three minutes later! Fortunately, there wasn't a scratch on the aircraft, myself, or anything else. The plane had been retro-fitted with a three-bladed prop, and a larger 300 hp engine (versus the original 230 hp), so although it's rate of climb was spectacular when everything was working, it's gliding ability was certainly degraded compared to the handbook's distance graph. As far as the Electra goes, even with flaps and gear retracted, I'd say that with two windmilling props and those big draggy radials hanging in the slipstream, it would almost come down like an anvil chained to a piano!

The ability to fund any given project is directly proportional to the public knowledge of the question and desire for the answer to be found. Amelia is on of those names like Winston or Adolf where you don't even need to say the surname. To most people, Nungeeser and Coli sounds like a law firm in Montreal. I'm hoping that eventual success on the Earhart Project will create an appetite for an encore that will let us really go after a truly historic lost airplane - l'Oiseau Blanc.

However, I don't recall anyone factoring Noonan into why there wasn't an SOS with position report final message. He spent 20 years at sea and was a Master who could captain any size ocean going vessel. I don't think he would have ended up in the water without providing a last position report if it was humanly possible. He would have been acutely aware of the fuel situation (can't plot a course anywhere without knowing what it is). And, as I understand it, he plotted navigation positions in advance of the actual location so he wouldn't have needed to wait until the last ten minutes to start furiously calculating. Even if he thought he was within 10 miles of Howland, given his background, I can't see him going into the drink without a final position report. Of course, if the equipment failed... blue skies, -jerry LTM (who just spent $0.02 she probably shouldn't have) ========================================================================= Date: Sun, 5 Dec 1999 11:08:55 EST From: Don Neumann Subject: ditching Ditching an aircraft in water might be likened to paddling a canoe though white water, you try to maintain the same rate of paddling to keep in front & on top of the wavewash created by the rushing water so you don't _drop_ (bow first) between the uneven crests & to maintain enough control to avoid being turned sideways. If you don't keep-up the same paddling rate you have little control of your craft & will quickly flounder & risk capsizing in the rough water. Since AE mentioned..."gas running low:.. on at least one occasion during her broadcasts, as recorded by Itaska, it doesn't seem likely she would be caught by surprise when the fuel tanks coughed-up the last drop of gasoline. Don Neumann *************************************************************************** From Ric In my experience, once you get down to the last dregs it's very hard to predict just when she's going to quit. Gas guages are not particularly accurate when the needle is bouncing on zero. As a kid, I had a co-pilot job flying a semipro ice hockey team around the northeastern U.S. and Canada in a DC-3. We used to routinely burn the auxillary tanks dry before swtiching to the mains, but if you let the engines cough once you immediately had 23 panicked hockey players in the cockpit with you. This tended to make the aircraft noseheavy and difficult to trim and so was to be avoided. The procedure was to watch the aux tank fuel guages until they started to bounce on zero then you switched your attention to the low fuel pressure warning light. At the first flicker you switched to the main tank and hit the boost pump. The engine in question never missed a beat. Once, many years later, I was ferrying a Piper Arrow (light single engine retractable) and was stupidly trying to minimize refueling stops. I was bucking a headwind and, consequentally, was flying at only about a thousand feet above the ground. I had burned one tank down as far as I dared and thought I was on the last quarter of the second tank when everthing suddenly got very quiet. I tapped on the fuel guage and the needle, which had hung up at the one quarter mark, abruptly clunked to zero like it had been shot. I immediately swtiched back to the "empty" other tank and hit the boost pump. The engine reawoke to my immense but only temporary relief. I knew that it would die again any minute and I decided that the next level thing I saw was going to get landed on (because you never, ever make a dead-stick, off-airport landing if you can avoid it). As it turned out, I spotted a windsock on a barn and put her down on a farmer's distressingly small private airstrip where he kept a J-3 Cub. He begrudgingly sold me enough gas to get to the next real airport. I can recall a few other occasions where my own rank stupidity left me chugging along staring at fuel guages that read "You're screwed" but each time the airplane made it to the next airport (although one time it did quit on the taxiway). The point of all this "there I was" nonsense is that you have to be even stupider than me to find yourself faced with a dead-stick landing.

As for Tofiga and Emily, though, they were pretty specific about having come off around the Ritiati/Noriti border opposite Kanawa Point. I'll make it a point to check with Tofiga the next time we correspond. Of course, they weren't travelling under the extreme weather conditions that plagued the Norwich City survivors, and they may have been using a canoe. TK ************************************************************************** From Ric Yes. It may be that the over-the-reef ferrying was done in a boat provided by the VITI in which case a canoe might have dropped them off on the lagoon side near Kanawa Point and there may have been a trail cut over to the ocean side. However, I can tell you from experience that you DON'T want to try to land a canoe in that pretty little cove just east of Kanawa Point. It's too shallow to get right up to the shoreline and when you step out of the boat to walk it to shore - GLOOP - you go right out of sight in quicksand unless you manage to grab the gunwale of the boat on your way down.

Malvone Subject: Re: ditching I have a question, has anybody thought that the plane may have come apart in the air and crashed either from a structure fault or maybe fuel explosion? ************************************************************************** From Ric Okay, let's consider those two hypotheses. 1. Inflight structural failure. Airplanes come apart in the air due to extreme forces that exceed their design limitations, or from a design or manufacturing flaw. Exreme forces can be caused by weather or by violent manuevers (sometimes spelled "manouevres"). There were no extreme weather conditions reported in the region and I know of no indication that the airplane engaged in violent ... thingys. The Lockheed Model 10 was, if anything, overbuilt and extremely strong. I've never heard of one coming apart in flight and NR16020 had already flown 2/3 of the way around the world safely. Seems like we can eliminate inflight structural failure as a likely explanation. 2. Fuel explosion If it happened it would sure bring things to an abrupt stop but, in the absence of any evidence to suggest that such a thing happened, it seems like a dead end as an investigative thread.

Good point. By the way, I saw the Halifax or what was left of it, after its recovery. There was hardly anything that could be used to help restore another Halifax but the twisted metal did have exhibition value. I remember one of the huge wheels was still intact and inflated... I mentioned that Halifax some time ago in the forum because the way it was recovered showed similarities with what TIGHAR is trying to achieve with the Electra. In this case a group of dedicated aviation enthusiasts with an interest in "aviation archeology" knew more or less where the airplane crashed. Some older inhabitants of the village recalled that it crashed in a bog one night in 1943. The Germans had tried to recover it but had given up as it sank deeper in the bog, although they did succeed in extracting some of the aircrew for burial. Then the airplane disappeared in the bog. It was in a densely populated area, unlike Gardner Island. Nobody cared to look for it for the next 50 years. But learning it was there, the entusiasts convinced the Canadian government to help them recover the bomber and the Canadian government indeed paid for the rent of a crane to raise the wreck, in order to give the missing crewmembers a proper burial. They were indeed buried as David described. The enthusiasts were the same bunch of motivated people members of the TIGHAR expeditions are. They believed they would succeed and they did. With some help from the Canadian government, which was mainly interested ingiving the missing crew members a decent burial. In addition they got their Halifax back for exhibit in a war museum. Couldn't the US government be convinced that TIGHAR can find the Electra and found willing to provide some support for the recovery from Gardner Island ? Let me cite two examples of government aid that both happened here. Some years ago the Brussels Air Museum learned they could have a Canadian CF-100 for free for the museum, provided they took charge of transportation from Canada to Brussels. As the Belgian air force had operated the type in the Fifties, the Ministry of Defense simply ordered a navy ship to Canada to go and fetch the airplane. Officially the vessel was sent on a "goodwill tour" to Canada... The aircraft is now on permanent exhibit in Brussels. Some ten years ago the same museum learned it could have a Westland Lysander airplane, of the type used by the RAF for covert operation in WW2. As Belgian agents were flown into occupied Europe in such airplane, again the ministry of Defense was found willing to help. It ordered the air force to send a C-130 to Canada to collect it. In fact it was a wreck. It has been lovingly restored to FLYING CONDITION by a number of dedicated volunteers. I saw it flying over my home only last week. . Perhaps in Europe we are more attached to relics of the past. But I remember having seen beautifully restored historic airplanes in the US also. Couldn't the US government then be convinced AE is part of American heritage and that therefore it would be worthwhile using some of the formidable resources at its disposal to go to Niku and comb the place ? LTM from Herman (who loves old airplanes, even if they're bent a bit) ************************************************************************* From Ric We have, from time to time, received help from the U.S. government in the form of donated expertise and laboratory work by the FBI, the NTSB, and even the CIA (but don't tell anybody). On other occasions we have been unsuccessful in getting help from other government agencies. Aviation historic preservation in the U.S. is, as it is in Europe, the exception rather than the rule. Rare indeed are the museums who understand that you can't preserve something by throwing most of it away and building something new that looks like the old thing. In this country the National Museum of Naval Aviation is doing some good preservation work and in England the RAF Museum at Hendon and the Imperail War Museum have some good examples of preserved aircraft. On the continent, the Netherlands Military Aviation Museum at Soesterberg has been a leader in the field. In Australia the Australian War Memorial Museum has pioneered some important preservation techniques and in Canada the National Museum in Ottawa has a couple of interesting projects going.

Earhart's accomplishments, and her failures, are a matter of record. What's true for her flying ability is even more true of her character. Some see her as a hero and role model. Others see her as less than that. What is beyond question is that she has become legendary. ========================================================================= Date: Sun, 5 Dec 1999 18:06:53 EST From: Greg Subject: More Odds and Ends I have been thinking a little about the radio related items here and at the risk of covering old ground and boring people to sleep I offer the following thoughts. 1) You said that the radio system was in two boxes at disparate points ie receiver up front and transmitter in back. So musing a bit, in many of the earlier avionic systems the receive antenna and the transmit antenna were separate and the receiver system was used both to navigate and to receive incoming messages during communication. In one version of the concept there is no antenna changeover switch from receive to transmit because it does not use a common antenna for communication. In fact King Radio made the last of these as the KX145 up to about ten years ago. Genave also made a unit called the A200. It is an efficient way to put navigation and communication in the airplane. I do not know that this was the case here but it seems plausable. In the 1930's the reasons would be; WEIGHT, POWER CONSUMPTION, and COST. I put these in capital letters because the penalties were huge then. Perhaps someone has the actual equipment manuals for these components including the suggested antenna arrangements. It could be that the design of the antennas aboard the 10E were taken directly from the radio manufacturers manuals. 2) We know AE could effectively transmit and ineffectively receive. The records show this. It implies that the airborne transmitter system (the antenna is a part of the system) was functioning significantly better than the receive system during communications. We also know that the navigation receiver was not functioning correctly. Could this system installation have been the common receive antenna for nav and com as noted above? 3) If all that was left of the receive antenna (electrically viewed from the radio) was a small part of the feed exposed past the sheet metal then, the receive sensitivity would be hugely diminshed. That is, the required field strength for audible reception would have been increased by easily 40 dB (each 10 dB corresponds to a factor of 10 so 40 dB is a factor of 10,000) and perhaps an much as 60 dB (a factor of 1 million). What this implies is that in order for her to have received anything she would have had to have been very close to the sender. Exactly how close cannot be known but there is a bit more information here in that there was enough signal to be heard intermittently but not to null or point. By the way, could it be that the receiver was mounted under the right front seat in order to shorten or effectively eliminate the lead to the antenna? A smart idea if one is trying to get the most out of a receiver. If so then the antenna was electrically coupled to the end nearest the cockpit. This might help explain why AE could hear anything with only the stub as the actual receiver input impedance may have been high enough to allow the stub to operate nearly unloaded (but also unmatched). Similar to todays LORAN antennas which are unloaded by the preamplifier either in the antenna base or in a preamplifier nearby. 4) I also think that it is reasonable to believe that if all that was left of the antenna was a stub, then the antenna sensitivity may have had a large null in the pattern caused by the fuselage obstructing the incoming wave from the pilots side, thus making turns necessary to find a strong enough signal to hear. The additional null(s) may have grossly interfered with any attempt to use the loop. 5) There have been comments here about line of sight and the difficulties of communicating at VHF. But AE was not transmitting at VHF and the propagation charactistics of 3 and 6 MHz are not the same as those which pilots experience at VHF. The guys who use HF up in Canada, Alaska, over the Atlantic or Pacific can perhaps share what they have experienced using it. In addition as noted here previously the expected propagation at 6 MHz is not the same as 3 MHz. I remember that Northwest used something around 7 MHz for transatlantic communications. \_ Greg _/ ************************************************************************** From Ric This is, I'm afraid, very old and well-trampled ground.

The best response to these contentions is the fact that AE/FN had flown over three quarters of the way around the world, under what at times could be described as less than optimal conditions, with no reported instances of any problems directly related to any breech or lack of piloting/navigational skills. I seem to recall that those observing the takeoff from Lae expressed their admiration at AE's ability to handle the heavily, fuel laden Electra & get it airborne within the constraints of the somewhat primative conditions of the runway at Lae. From the various reports from the flight, subsequent to takeoff, that are available, the flight appeared to be going well, giving the impression they were probably on course through the Gilberts. Whatever problem caused them to _miss_ Howland Island, would seem to have developed or become apparent, during that last 600-700 mile portion of the 2500 mile (longest) overwater leg of the flight. While AE's piloting skills may have been subject to question before the round-the-world flight attempt, there seems to be little doubt that she was an expert at handling the Electra & all it's idiosyncrasies by the time she lifted off the runway at Lae. Don Neumann ************************************************************************** From Ric I agree. ========================================================================= Date: Sun, 5 Dec 1999 18:20:12 EST From: Ross Devitt Subject: Navigation I received this in answer to a post to Ric and agree it would be good to see what forum members thought (It started out as just a photocopy of a map......) My comments are next to the ***. The full text of the original post is right at the bottom. The text with a map (300kb) is at: http://www.ross.devitt.com/amelia Ross, If the 5:18 p.m. position report of 4.33 South, 159.7 East is accurate, it places the aircraft on the direct Great Circle from Lae to Howland and almost exactly over the Nukumanu Islands at 4.30 South, 159.30 East. My trusty Encyclopedia Britannica puts the Ontong Java Islands at 5.20 South, 159.30 East. Just about exactly one degree of latitude to the south of the Nukumanu group they seem to be a possibility but it would mean that Fred isn't where he thinks he is. *** My point exactly. for the reasons below and in the text I think he was out a bit. 1 it was dark 2 there was reported bad weather 3 they had to detour (absolutely NO PROOF that this happened, but....) As for what route they really followed to get there, I've seen several different opinions. Some say they diverted south to avoid high terrain on New Britain. That's a possibility but it seems like an awfully big detour if the 3:19 position is accurate. Your idea of avoiding the "dangerous rain squalls" is another possibility but it assumes that they heard the weather report that there is no evidence that they heard. *** The documented evidence points to the fact that they didn't get the weather report that came in as they took off, but they didn't have to hear. You can see bad rain storms for quite a distance. Cu clouds go way up, and they would not fly through them (the dangerous rain squalls) as heavily laden with fuel as they were, in fact I suspect they would not fly through them at all, as the reports seem to indicate that the aircraft was overloaded and the structural stresses placed on the airframe by turbulence - well i guess you've flown through it , you know what I mean. *** They would try to use the "1 in 60 rule" or whatever was applicable and go around and back on to their planned track. Or they could keep flying out at about the lattitude of Lae until they thought the squalls to their left were thinning and turn North East for Nukumanu. The other possibility, of course, is that they didn't deviate at all and that the 3:19 position was just heard or copied wrong. *** As suggested above, if (another "if") they saw bad weather ahead, they would probably contunue as close to due East (an easy compass bearing to follow) until they cleared the storms. I suggest that you put your ideas in a posting to the forum and invite people to look at your website. Should promote some interesting discussion. Ric *** OK, here is the text from the page. To the forum - this is "pure speculation" and the guesswork is done from an atlas not a chart, so the fact that I was only about one degree out on the location of Ongtong Java shocked me. The full text of my babbling can be found at the temporary web page on http://www.ross.devitt.com more interesting to new forum members might be the copy of the map from the atlas. It shows the direction of the "337/157" line that AE reported herself as flying. You can clearly see why TIGHAR expect to find she landed at Nikumororo (Gardner Island on the old atlas map). I have scribbled in the names of the other islands mentioned in the TIGHAR documents so you can see their relevant positions. Also, don't take too much notice of the ideas on navigation - unless as an active celestial navigator you would be kind enought to correct my errors. I did cel. nav theory (and a little prac) a very long time ago. ********************************** (This is a long post) Amelia Earhart and Fred Noonan departed Lae at 10am (Local Time) on July 2nd. All air navigation times are kept in UTC now, or Greenwich Mean Time back then. Lae is GMT + 10 hours, so Fred Noonan would have found the 10:00am local time convenient due to it being exactly midnight GMT. This would make calculations (up to the crossing of the International Date Line) relatively simple. Howland on the other hand is GMT - 11 hours. Some people calculate it as - 11hours 30 minutes, however normal practice is to use the "whole hour" for the time in a zone. It is often forgotten that the time zones do not follow the longitude meridians. A log was kept by Placer Dome, a mining company with an office at Lae, of most aspects of AE's operations at Lae. This report is in TIGHAR's web site and the times and reports below are taken from that. Amelia had arranged to transmit at 18 minutes past each hour to Lae station. For the first 4 hours the transmissions were not clear enough to make out her reports, then at last one partly intelligible report came through. At 2:18pm, AE reported her height as 7,000ft, her speed as 140 knots and something else that could not be heard. By this time she was 4.3 hours out from Lae. At 140 Knots/no wind she would have travelled just about 600 nautical miles. If the wind she reported later was a headwind, and was current for the early part of the flight, she would have been only about 440 nautical miles out. At 3:19pm, Earhart's reported position was received as "150.7E, 7.3S". This is strange, as that position was about 150 nautical miles South East of Lae. If the time was logged in Local Time, it would mean they were covering about 28 nautical miles an hour over the ground for the first 5.3 hours. The 150.7East is certainly wrong, probably due to the radio interference reported on AE's earlier transmissions. The 7.3South is interesting however, as when the Electra was taking off, a weather report was received at Lae warning of 24/25 knot easterly winds and "dangerous rain squalls" about 300 miles east of Lae. This put bad weather between The Island of New Britain and the Solomon Islands. No pilot in their right mind flies through "dangerous rain squalls" intentionally, so it appears that AE might have kept south of the bad weather for about 5 hours (assuming the 7.3S is correct.). That would put them about 157.7East, which is much more likely. From there they would have to divert back on to their planned track, and there was only one land mark available on the track that did not involve flying back in the direction they had come from. Turning to a heading of somewhere around 020 would have brought them over a scattered group of atolls and islands in about 2 hours. At 5:18pm, they reported to Lae that they were at "4.33South, 159.7East at 8,000 ft over Cumulus Clouds wind 23 knots". This places them (if it is accurate) about 750 nautical miles out from Lae and probably just over the Ongtong Java Is. Which would be convenient as if he could see them would give FN a visual fix on a small group of tiny island atolls. If FN's position was correct, and if he used Ontong as a visual fix (remembering that cumulous cloud does not always cover the whole sky) then the 23 knot wind they reported was a head wind as the Electra had only covered the ground at an average of about 103 nautical miles per hour. (This tallies pretty well with a 23 knot headwind, and an indicated airspeed of 140 knots. Also, if Fred Noonan did get a visual fix on Ongtong, his time and distance calculations would have confirmed an average headwind of 23 knots. I my personal theory is that this is exactly what he has done. It seems just too much of a coincidence that his position reports him almost exactly over this group. And without knowing his exact position he had absolutely no way of calculating the wind. Ongtong is pretty much the last landfall before the Gilbert group about 900 nautical miles away. Another reason why I believe Fred Noonan would have used Ongtong as a visual reference for his ded reckoning. That was the last transmission received by Lae station, although they listened unsucessfuly for the Electra for another three hours. Now, if FN was using Ongtong to get his last definite visual fix before heading out over the deep blue sea (and as it is almost in a direct line from Lae to Howland I'm sure I would). And If his position report at 5:19pm ws correct (it puts him pretty well right there), and IF my theory about staying south of the "dangerous rain squalls" for almost 3 and a half hours was correct, then FN had a little problem. If he could fly a straight line from Lae to Ongtong, he would not only be able to work out his ground speed, but also his "drift", the distance the wind was blowing him from his planned track for the first 1/3rd of his flight. If, on the other hand, AE had to stay south of the weather (a not uncommon occurence around heavy rain), then the next chance he would have of getting a visual would be over the Gilbert group. It is recorded that the lights at the mines on Nauru were going to be left on all night for the aviators to pick up a visual reference, but depending on the weather that night, a soft glow about 150 miles to the north of them would not provide a "fix" of his position. It is also unlikely that FN could get an exact fix over the Gilbert Islands at night either. That means his drift calculations depended entirely on Celestial Navigation. Not something I'd like count on too much in an aircraft at night. Another reason I believe FN would have picked Ongtong for his last landfall is that a direct line from Lae, through the group seems to come out pretty close to the line between Howland Island, and Baker Island (just to the S.E of Howland.) It would be a safer bet to aim for a spot right in the middle between those two islands so close together that they would be bound to see one or the other as they flew through. I don't believe it is a coincidence that the bearing and reciprocal of 337/157 just happens to be as close as I can get to the bearing and reciprocal of the Howland/Baker combination. Once the sun came above 20 degrees over the horizon, FN would have used the sextant to get a "sun shot". That would tell him how far North or South they were. Another one some hours later would be needed to give them a longitude fix (East/West). This assumes that he could get a clear shot at the sun. Clouds can foul up sextant sun shots like you wouldn't believe. If the head wind dropped to around 13 knots during the night, the Electra would be over Howland some time around 18:30 GMT or 18 and a half hours flying time at about 125/130 knots during the night. Now For The Fun Part.... If FN and AE missed sighting Howland, and obviously they knew they had to be close to 176.38 Longitude by then there was really only ONE viable option. If FN calculated the LOP that they were on, then using his calculated average ground speed, advanced it to Howland, he would then have an estimated time to arrive over the island. When they could not see Howland or Baker at that time, they had to be either North or South of Howland by a fairly large distance (visibility was reported at 20 miles at sea level in the vicinity - of course sometimes in the morning in the tropics, there is a haze over the sea and horizon, and you actually can't see as far as you can at sea level). Bear in mind that Howland is only 10 feet high at its highest point, and only a mile and a half long by half a mile wide. Most of it is no more than a metre above the water. The whole thing is reported to be almost 3 times the size of The Mall in Washington, DC. If they were anywhere North on longitude 176.38E , then there was no way they would turn LEFT to 337 degrees. There is nothing out there but water. To find either Howland or Baker they would need to know exactly how South they were to know how far to fly PAST the LOP to turn North West. If they knew that, they would not be in the predicament in the first place. Turning RIGHT to 157 on the other hand virtually anywhere within 150 miles either side of Howland's position on Lattitude 176.38 , and especially if they flew "past" Howland, WOULD bring them into enough islands to at least get themselves a visual fix on more than one island. Flying a little over 2 hours at 140knots would bring them into the middle of a group of islands, and a chance of setting down intact. I believe it was NO COINCIDENCE that they were flying the 337/157 line, and under no circumstances would they consider heading out at 337. So there it is. A little story to go along with the picture above of the general area where the flight and searches took place. This is my reasoning based on what I'd plan for the same trip, and compared with the reports received by the US Coast Guard Cutter Itasca and the radio operator at Lae. There are numerous variations - almost everyone has a theory. Some day I'll get hold of the full set of charts covering this area and check this out more accurately. For an "in depth" view of the search for Amelia Earhart, and up to date information on research and actual searches go to http://www.tighar.org There you'll find information on artifacts that have been recovered during an extensive search for Amelia earhart's Locheed Electra along with documents and reports from the period.

During AE's crossing of the Pacific towards Hawaii, she gave several position reports, none of which contained a time associated with the position. Reconstructing the maps used (to be reported in the 8th Edition), I was able to determine that none of the position reports were celestial: all were dead reckon positions. All were determined prior to the actual time of the report. and represent projected positions at such and such a time (which didn't correspond to the scheduled radio broadcast). Examining FN's chart of the Atlantic crossing and of maps across the US, he simply took the nominal flight speed and course and plotted estimated positions in the future for cross-referencing should a landmark be sighted. Obviously, this doesn't always work across water, but the plots are there for the Atlantic. Since the Nukumanu Island position report is so close to the great circle/rhumb line of the projected course, I feel that this position report is a projected dead reckon position, and given to AE to give her some semblance of where the plane was. I don't believe her modus operandi was to provide information sufficiently detailed nor accurate enough for flight reconstruction. OK, I'm ready to take the hits. ************************************************************************** From Ric I agree with Randy. Earhart doesn't seem to have ever gotten the idea about what a postion report is supposed to be.

Ric summed up a list of very interesting aviation museums. For the benefit of forum members who are interested in the Lockheed 10, I'd like to add an information which is hot from the needle. Anyone who'd like to see a rare Lockheed 10A Electra will be able to do so soon in the new section of the London Science Museum at Kensington now being prepared. The historic airliner will be part of a new permanent exhibition entitled "The making of the Modern World" and the display will extend exhibition areas by a third and illustrate "History of Industrialisation and Technology" from 1750 to the present. It will also include the Apollo 10 space capsule and the Stephenson Rocket (which is not a space rocket but happens to be the world's very first steam locomotive). The exhibit opens in June 2000, so make a note in your agenda, gentlemen. This is a must on your next trip to Europe... I also like to add to Ric's mentioning the the RAF Museum at Hendon (London) that I believe the latter is rather of a temple where aviation is worshipped than just of museum. I consider it one of the best in the world. As for the Imperial War Museum at Duxford (near Cambridge, England), it is home to practically anything that flew in WW2, both in European skies and over the Pacific. It also houses the Museum of the us 8th Air Force. Most of it is in flying condition. Each summer they do WW2 over live with all these historic airworthy airplanes, including Spitfires, Hurricanes, Messersmitts 109, Blenheims, P-40 Kittykawks, P-47 Thunderbolts, P-51 Mustangs, B-17, B-25, Lancasters, Grumman F4F Wildcat, F6F Hellcat, Grumman TBF Avenger, Chance-vought F4U Corsairs, PBY Catalina, the lot... They have recently acquired a Mitsubishi Zero. Anyone interested let me know. I can let you know the dates of the shows, so you can plan your next trip to Europe accordingly (yes, you can fly in with your own airplane if you want to and save time. Mind you, you'll have to file a flight plan...). To Ric's list I'd like to add two more : the Smithsonian Air and Space Museum in Washington, which is arguably the most comprehensive on development of flight, and the USAF museum at Marshfield AFB, California. The latter is part of a USAF airbase and seems to have one example of anything that flew in USAF livery since 1945 until this day, including SR-71. But that, I'm sure, most US forum members may be aware of. I just wanted to add them for good measure. LTM from Herman (who loves old planes) ************************************************************************* From Ric This is pretty off-topic but it was my impression that the Imperial War Museum does not attempt to rebuild its artifacts to airworthy condition. The airplanes that fly at the big WWII airshow at Duxford belong to private collectors like Stephen Grey of The Fighter Collection. Be assured that no World War Two aircraft fly in modern airshows. Surviving examples of World War Two types are often used as the foundation for rebuilt replicas of themselves. It's a multi-million dollar entertainment industry and it's great fun, but it's not historic preservation. ========================================================================= Date: Mon, 6 Dec 1999 11:48:06 EST From: William Webster-Garman Subject: aviation progress Dave Porter wrote: > after going to the moon, our space program consists of: >A. losing hardware in the vicinity of Mars, and >B. doing laps around the planet in an > outer-space pickup truck that was designed in the 1970's. Interestingly, while most of the avionics and control elements of the shuttles have been totally redesigned, modernized and upgraded repeatedly throughout the 80s and 90s, the basic airframe of today's space shuttle was actually designed in the late 60s, when NASA knew that one way or another congress would force them into some sort of effort at more economical space flight after the Apollo program. There is a parallel with the Boeing 747, which first flew regularly in 1969. The same basic airframe design is in use, which in the case of this aircraft has been enormously safe and successful, but a 747 pilot from 1970 wouldn't at all recognize the cockpit of a 1999 model 747: Inside, 30 years later, it's a very different aircraft. That the same airframe is still being manufactured for new planes probably indicates enormous skill on the part of aviation designers at Boeing in the 1960s. I wonder what Earhart would have felt if she had lived long enough to fly non-stop from LA to Tokyo in a 747? william 2243 (who feels more secure out over the Pacific or Atlantic ocean in a 747 operated and maintained by a reputable airline than on a local freeway, and has recently become fond of the 777) ========================================================================= Date: Mon, 6 Dec 1999 11:57:27 EST From: Jim Razzi Subject: Re: forum statistics I think "lurkers" was rather an unfortunate term to use to describe those who for one reason or another can't afford to pay or choose not to .

Jim Razzi ========================================================================= Date: Mon, 6 Dec 1999 19:24:54 EST From: Herman De Wulf Subject: preservation Ric, Contrary to what you believe they do have authentic WW2 airplanes in flying condition at Duxford. They have been overhauled or restored of course. The Spitfires are mostly former RAF gate guardians restored to flying conditon. They crashed an authentic Me-109G last year. It had been captured in the Lybian desert in 1943. It was flown by an RAF Vice Air Marshall. At this moment they are restoring an Avro York transport to flying condition. Many aircraft in the show are indeed privately owned indeed. On the 60th anniversary of the first flight of the Spitfire (1936) they managed to put 20 into the air. P-51s too are authentic, as are PBY's, TBM, F4F, F6F and F4U. Some of these are ex-French. Many are indeed owned by private collectors, like the nearby Shuttleworth Collection at Old Warden. In addition the RAF still has -believe it or not- at least one Spitfire, one Hurricane and one Lancaster in its inventory. Herman *************************************************************************** From Ric Herman, you completely missed my point. Historic preservation is the saving and safeguarding of relics from the past - that is, the physical material that was there then and is here now. If archaeologists found the remains of a chariot in a pharoah's tomb nobody would say, "Well, the harness has got to go but we can build a new one and we'll have to replace most of the wood, but with some work we should be able to make this baby as good as new." If somebody did that no one would say, "Wow, look at that. An authentic Egyptian chariot in horse-worthy condition." Airplanes, like automobiles, are still too new to be valued by the public as historic properties. Most of what passes for aviation and automotive preservation is, in fact, the creation of reproductions using some original material for the sake of nostalgia, education and entertainment. I hasten to say that there's nothing wrong with that. A World War Two airshow can be genuinely educational, tremendously moving, and tons of fun. However, the cost of failing to recognize the difference between the real thing and a play actor is to risk destroying artifacts of great rarity in the name of "preservation." A classic example is the P-38 Lightning removed at great risk and expense from the Greenland icecap several years ago. Other than being a bit squished, the aircraft was almost perfectly preserved - paint, leather, everything - but because the intent of the salvors was to end up with a flyable airplane, very little of what came out of the ice has been saved in the process of rebuilding the machine. It's a question of economics. A flyable P-38 is worth a million dollars or more. The only all-original WWII P-38 in captivity wasn't worth anything. Many years ago, TIGHAR adopted as its motto a quote adapted from the Stonehenge Manuscripts of 1660 by John Aubrey: "Let us bend our best efforts to the preservation of antiquites that they might escape the teeth of time and the hands of mistaken zeal." LTM, Ric ========================================================================= Date: Mon, 6 Dec 1999 19:28:16 EST From: Don Neumann Subject: Dead Stick Landing >The point of all this "there I was" nonsense is that you have to be >even stupider than me to find yourself faced with a dead-stick landing. > >LTM, >Ric Remind me not to allow my grandchildren to fly with you! I must agree that given any choice in the matter, AE would have (speculation) elected to ditch the electra with full power, however, I must say that if she were pushing to reach an island landfall (Gardner) in the Phoenix chain & if the fuel guage(s) didn't accurately record when the engines were actually breathing fumes, it remains a _possibility_ that she could (speculation again) have hit the water (dead stick) just short of her objective, leaving she & Fred with a swim to the beach, assumng the Electra didn't splashdown nose first . In any event, she'd have been too far out of radio range to SOS the Itaska (steaming NNW of Howland) anyway. Of course, that scenario nixes any post landing radio transmissions. My own personal, undocumented, purely emotional opinion is that if she got within sighting distance of Gardner ( or, to accomodate all the other theories) any other landfall, she would somehow have coaxed the last drop of fuel out of those tanks, in order to make a wheels down landing on any available reef flat! One more thing, after viewing the Electra model schematic drawings, I would be inclined to think that lateral view from the cockpit of anything to port or starboard would have been nigh impossible, with two big P & W engines hanging forward of the wing, limiting visability to the horizon, straight ahead. Best lateral visability would have been from the two midship windows adjacent to Fred's navigational table. Don Neumann ========================================================================= Date: Mon, 6 Dec 1999 19:56:34 EST From: Ross Devitt Subject: Re: Navigation Randy would have to be correct here, for the flight over water. Deduced reckoning was the only navigation technique available to private pilots up until a few years ago. Radio Direction Finding and visual or celestial fixes simply allow you to check your navigation and correct it. So my point is that the first longitude position report has to be wrong (probably written down incorrectly) for the time flown - but the lattitude is probably correct. That would get them around the storm near New Britain. For FN to get them so far wrong that early in the flight is very unlikely. (There's no way they did 4 hours at 28 knots.) And the second one would have been their last "visual" fix (the actual sighting of Nukumanu) to put them back on their planned track for Howland. Navigation requires that they actually "knew" where they were on the starting end of their planned track, and what direction "heading or bearing - depending how you look at it" to fly to get there. They needed a visual fix before leaving land - and the last possible visual fix is Nukumanu. Passing Nauru in the darkness they may (or may not) have seen the glow from the lights way off to their left. That would give FN a confirmation of his Longitude (perhaps) and even some vague confirmation of Lattitude. Remember, as well as huge mine workings being lit all night, there was a 5000 candlepower (pretty bright for those days) light set up a long way off the ground. We can see the ordinary lights from our coalfield draglines and coastal towns for a long way at night and often use them to confirm our ground speed. I imagine the Gilbert islands at night would be another matter though. I still can't see FN being too far from where he thought he was when he reached the Howland end. RD ************************************************************************** From Ric My only comment is a cautionary one. We don't have any evidence of a storm near New Britain. All we have is a forecast which starts with the words "Accurate forecast difficult account lack of reports your vicinity" and mentions "no major storm, apparently partly cloudy with dangerous local rain squalls about 300 miles east of Lae...". ========================================================================= Date: Tue, 7 Dec 1999 08:41:14 EST From: Herman De Wulf Subject: Re: museums Thanks for corracting me Jim, I wasn't sure of the spelling.

Herman ========================================================================= Date: Tue, 7 Dec 1999 08:47:11 EST From: Herman De Wulf Subject: Re: preservation I guess I won't be able to convince you. Of course you're right in your criticism of the "aircraft preservation industry", as you know it to exist in the US. Some museums and some companies indeed rebuild historic aircraft using one original and canibalizing other airplanes to make one new one. The same happens over here. But... But the Messerschmitt Me-109G that the RAF Vice Air Mashall crashed last year ( pilot overshooting the runway at Duxford in an emergency landing because of trouble with the ORIGINAL engine) was not privately owned. It was British government property and a genuine German Me-109G that had been captured by the British in Tunis in 1943. It had been brought to Britain for flight trials at Boscombe Down and had been stored at the end of the war until the Imperial War Museum decided to bring it out again, because it was in good condition after all, and fly it after an engine overhaul (this being the original Daimler Benz 601 and not the British Rolls Royce Merlin you'll find in some Spanish license-built examples). It flew in its original 1943 Luftwaffe desert scheme colours. I saw it. I made pictures of it. There are guys out there in England who fly authentic Consolidated PBY Catalina's. Of course the engines have been overhauled. But those are not rebuilt airplanes. The Spitfire, the Hurricane and the Avro Lancaster bomber I mentioned are owned by the RAF. They are not part of an "industry". They're just well maintained at great expense, by the RAF and fly, not for commercial reasons but to remind the British nation they won WW2. Compare them to the US Navy keeping the USS Constitution as a piece of American Heritage in Boston harbor, if you like. I know a guy in Belgium (one Karel Bos, who lives in Brasschaat) who owns a 1945 built Vickers Supermarine Spitfire XIV with an original Rolls Royce Merlin engine. Of course it has been overhauled since TBO of those engines was only 250 hours... But the airplane as such has not been "rebuilt", it has simply been maintained in flying condition. You can see and touch it in its hangar at Antwerp airport. Karel Bos (now 70) flies it purely for fun, mostly on sunny Sunday afternoons. I reckon he's the oldest Spitfire pilot in the world. He's not a professionl pilot. He has a PPL. I feel it will be difficult to convince you, probably because you have so many examples around you in the US where historic airplanes that are really replicas. But over here we have some authentic Boeing B-17 Flying Fortresses flying around. Those too are privately owned. They have never been rebuilt. They have been extensively repaired, their engines have been overhauled according to requirements. These aircraft are genuine. They have not been "restored" by canibalisation of others, nor have they been rebuilt like some of the Lindbergh Ryan NYP replicas or the Vicker Vimy that flew to Australia.

Again, I am forced to conclude (speculate?) that the position was simply a point on the great circle route, pre-plotted, and that the position relative to an island was pure coincidence. ************************************************************************* From Ric I tend to agree with you on this. somewhere along the line somebody noticed that the position given was close to those islands and suddenly it's received wisdom that Fred saw the Nukumanu Islands. ========================================================================= Date: Tue, 7 Dec 1999 10:17:51 EST From: Tom Cook Subject: Preservation / Restoration Ric: I know that we've been over this before, but what do you do if the artifact has been modified before you get it, do you attempt to return it to the condition of historic significance, or do you preserve it just as you received it? Example: The Hughes HK1 (AKA SPRUCE GOOSE) It had to be disassembled to be moved from Longbeech CA to McMinnville OR. While it was at Longbeech it was painted with a thick white "fireproofing" paint so it did not look like it did when new, or when it made it's one and only flight. I have been told that he engines had been changed from 3000 hp R4360's to a later model that developed 3500 hp, because Howard Hughes considered it underpowered, he also had an airconditioning system installed to keep the pilot cool and there is a spiral staircase that was installed after the flight to replace the extension ladder that can be seen in pictures taken at the time of the flight. The linen fabric that covered the control surfaces which had been painted has been replaced with new polyester fabric (and a good job it is) and I have been told that they are sanding the white paint off the hull and wings. BTW they have made progress on the new permanent museum, they have graded the site and poured a lot of concrete in the past year. The plan is to reassemble the Hk1 and exhibit in the new museum along with the rest of their collection which includes a Me109g, a Spitfire a C47, a B 17, a Ford Trimotor, a BD5, a Dehaviland Vampire, Howard Hughes personal Hughes helicopter (serial#2) and many more. Their website is www.sprucegoose.org With regard to tension in the cockpit, I wonder how accurately A/E could tell how close to fuel exhaustion she was with all those one of a kind fuel tanks, I would think that if she had never run them dry, she might not know EXACTLY how far the needle would go before the engines cut out. Could she read the levels in the various tanks without actually switching tanks? I have a friend who crash landed a F6F Hellcat near Portland OR a few years ago because he couldn't get his fuel switch over valve to work, Both he and the A/C survived, but with considerable damage. Dead stick landings are HELL!! My brother had a engine failure in a Tripacer over a city in CA several years ago, when he called "MAYDAY" he was directed to a small nearby airport where he was able to land safely. A while back we discussed post loss radio signals and how much A/E would have had to run the engine to keep the batteries up enough to operate the radio and ensure enough power for a restart the next time. The manual for the HK1 says not to run the engines below 1400 rpm for more than 15 minutes unless an APU is hooked up to keep the batteries charged, I know, a 10E and the HK1 are different airplanes, but they both used P&W Wasp engines (different sizes, OK, a LOT different) They were built about 10 years apart. LTM who knows a 10E from the HK1 TC 2127 *************************************************************************** From Ric Before I reply to your preservation question I want to emphasize that this stuff is not just my purist opinion. Standards, procedures, and definitions for historic preservation have been hammered out over the past hundred years or more by scholars, curators and conservators in museums around the world. The problem is that most air museums and aviation enthusiasts are not familiar with this immense field of study or, if they are, somehow feel that airplanes are exempt from the rules that apply to everything else. In an attempt to make this information more accessible to the aviation community we have published The TIGHAR Guide to Aviation Historic Preservation Terminology which is now used by many air museums in the U.S. and Europe. We should probably put it up on the TIGHAR website in the Preservation section. Okay. Here's a short course. "Original" means the same physical material ("fabric" in the parlance of the discipline) that is passed down from a particular time in history. It does not mean new stuff that is just like the old stuff or old stuff from some other object). Lindbergh's "Spirit of St. Louis" in the Smithsonian is not original to his transatlanitc flight. It is largely original to 1928 when it arrived at the museum following Slim's grand tour of the U.S. and Central America. Saying an aircraft is "original" is meaningless unless you provide a reference date. The older an airplane is, the less likely it is to be all "original" to its manufacture date or it's period of historical significance. "Restoration" means returning the existing "fabric" of an object to a known earlier state through the minimal introduction of new material. This is what your'e talking about with the HK-1. Sand off a later layer of paint, replace some headliner, clean it up, etc. You can't make it "original" to the famous test flight unless you find the old engines (not engines just like the old engines but the actual engines that were on the airplane) and tear out the air conditioner and staircase and find that old extension ladder. Probably ain't gonna happen. The HK-1 will, at best, be a "restored" version of the airplane as it was whenever they stopped messing with it. The "Spirit of St. Louis" has been restored through the replacement of the clear overhead panel that had yellowed and split over time. You can return something to a known earlier appearance through repair and the introduction of substantial new material (new skins, new wiring, overhauled engines, new paint, etc.) but now you have a "reconstruction." If you decide to make it look like something it never was (paint an airplane in the colors of a famous ace, for example) then you have a "conversion." In both cases, the object has lost it's "historical integrity." If you decide to return the object to service rather than preserve it you have a "rehabilitation." Like I said originally, there is very little aviation historic preservation going on anywhere. It's getting better, but very slowly. LTM, Ric ************************************************************************** From Dennis McGee A short version of Ric's recent preservation/restoration speech aired here would be a statement I heard several years ago from a carpenter who came from a long line of woodworkers: "This is my grandfather's hatchet; dad replaced the handle and I replaced the blade."

As I live in what is loosely referred to as the tropics (around 20deg South) and as I previously lived in the proper tropics (closer to 10deg South - and not far from where all this happened), I know what happens to the weather up here. Perhaps I shouldn't be defending poor old Fred so much, but really, on a long distance flight like this it is the navigator's flight - not the pilot's. All the pilot has to do is point it where the navigator says! I can take off here in beautiful clear weather for a flight that's around 1.5 hours in the Baron at say 160 - 180 knots (Yep, I know it will go faster, but so does the fuel...) Not much different in speed from the Electra. 200 miles out, and I arrive at an airport I can't see, let alone land at. It is not at all unusual to be around 10 miles away in the local training area, and have to return to the airport because of weather closing in and a ceiling of 700ft and closing, when it was CAVOK half an hour before. When sailing, we have "Whitsunday Whiteouts". We can be smack in the middle of one of the busiest waterways in the world, and land withing 6 miles in all directions, and not able to see anything. This can happen in minutes. My point is not that there was a major storm, rather that no-one in their right mind flies through rain squalls up here... Especially around New Guinea - the clouds reach incredible heights, and they tend to have rocks in them... Not that there were any problems with that on AE's path, but the squalls would be very hard on even a strong looking aircraft like the Electra.

(sorry) ========================================================================= Date: Wed, 8 Dec 1999 15:05:31 EST From: William Webster-Garman Subject: difference between preservation and maintenance One of the differences between "preservation", as Ric describes, and "maintenance", as Herman has been describing, is very simple: By definition, one doesn't preserve an historic aircraft by flying it and exposing it to risk, as in Herman's example of "the Messerschmitt Me-109G that the RAF Vice Air Marshall crashed last year ( pilot overshooting the runway at Duxford in an emergency landing because of trouble with the ORIGINAL engine)". That Me-109G wasn't being preserved, it was being maintained for flight (original equipment not withstanding), and since flight was the priority, the aircraft was ultimately degraded, not preserved. By definition, one doesn't fly aircraft that are under preservation. For example, in the very unlikely event that the Earhart Electra was somehow found pristine and intact, and somebody managed to "overhaul" the engines etc and get it into the air, this act would be the antithesis of preservation (i.e. protection) and would cause great discomfort to many aircraft historians and others among us who appreciate the educational and cultural benefits of true artifact preservation. LTM (who was well maintained if not well preserved) william 2243 *************************************************************************** From Ross Devitt In the Queensland Museum, Brisbane, Australia about 10 - 15 years ago (Brissy is a hell of a long way south) I saw the aircraft belonging to one of our Australian pioneer aviators. It was a steel & timber frame, fabric covering, and had crashed in the desert back in the thirties. I can't remember without checking - I think it was the Kookaburra which went missing in the Kimberley (like a larger version of Death Valley - much larger). It was found not all that long before I saw it. Point is it had been "preserved" as it was found. Crumpled, sand abraded, tattered bits of fabric. It hardly looked like an aircraft. The museum has taken photos of the site from all possible angles, treated the metal, wood and fabric with preservatives and displayed it as a diorama in as near to the original setting as possible. I think they may have left the pilot's remains out of the display..... I have seen examples of "restored" aircraft from a similar wreck. I suspect that this is close to what you would mean, Ric by "preservation" rather than "restoration"... Am I close (for a change)? RD ************************************************************************** From Ric Yes, the RAF Museum at Hendon has similar displays of a Hurricane and a Halifax but a thing doesn't have to look decrepit to be preserved. Sometines we get lucky and, due to some extraordinary circumstance, something survives for a long time in excellent condition. The point is, it what it is. There is no way to turn back the clock. *************************************************************************** From Tom King The Offishul U.S. Gummint definitions of things like "preservation," "restoration," and "rehabilitation" -- discussed with reference to historic buildings but generally applicable to airplanes too (and generally consistent with Ric's usage, though damn, Ric, do you have to be so snooty about it?) can be found at http://www2.cr.nps.gov/tps/secstan1.htm.

This is a VERY difficult and emotional issue and there is tremendous potential for misunderstanding and shoot-the-messenger feelings. As I have said many times, I have nothing against fixing up old airplanes and I love flying old types, but I do think that it's important not to kid ourselves about what constitutes preservation. ========================================================================= Date: Thu, 9 Dec 1999 09:09:52 EST From: Ross Devitt Subject: Re: Navigation End of thread...

One thread doesn't make a whole, but weaved together properly, we find a complete picture - its just knowing how to weave the threads together properly thats the trick. By the way - my daughter, a freshman in high school, had a project to do in history and (with a little nudging from ol' dad) decided to do one on our heroine. Thanks to TIGHAR for the fabulous website, she used many of the pics from "our" website, as well as the info and hypothesis. The project consists of two "project boards" back to back (most use only one) - she found fabric with little clouds all over it for the background, blank paper with clouds on it and then glued, pasted, taped, stapled all of it together into a very dramatic and interesting project - the grade isn't back yet, so I don't know what she and her team earned, but I'd give them an A+. Of course, I'm prejudiced, but those are the grades she typically gets on these things, so she has a track record that I can go by.

RESPECTFULLY, EVERYONE. ************************************************************************** From Ric As you'll see from the following postings, not everyone got the word that you speak for the entire forum. I tried to avoid this thread but it's apparent that at least some subscribers to the forum not only want to talk (fight?) about it but also feel that it is very much on-topic. Respecting their wishes, I'll post and respond to their comments. Fair warning - the rest of this posting deals with preservation. Anyone who feels as Chuck does should avail themselves of the delete key now. *************************************************************************** From Natko Katicic: Ric writes: "Herman, let's just drop the subject. It's completely off topic and it's pretty apparent that you just don't get what I'm talking about." Ric??? Off Topic? Do _I_ have to remind you what the acronym TIGHAR stands for? The International Group for Historic Aircraft Recovery. NOT The International Group for finding AE or educating the public. As I understand it, what Herman is talking about is your PRIMARY objective above all other projects. No Sir! To my mind this discussion is not off topic - not even on this forum. Regarding your dispute, I believe Hermann understands quite well that you mean "freezing" an airtifact [sic ;-)] in it's "as is" condition for future reference. Probably the word *Original* is the culprit for it is not an unambiguous notion. Herman is just talking of a differnet aspect of the notion *original* which in my opinion is quite as valid in the discussion about historic preservation in general. Last but not least, such a curt (to put it mildly. 'Rude' would probably be more adequate) reply to the impeccable posting of a regular, distinguished and until now aparently appreciated contributor intimidates and puts-off other forum participants as well - and Mother too. LTM (who has spoken - Haugh) Natko. ************************************************************************** From Ric Settle down Natko. Perhaps a little frustration but no rudeness was intended in my reply to Herman, and as you'll see from the posting below, none was apparently taken. Aviation historic preservation is certainly on-topic for TIGHAR in general and that's why we have a Preservation section on our wevbsite. For this forum, I'd like to limit the discussion to issues directly effecting the conservation and eventual curation and exhibition of artifacts found or hoped to be found in the course of the Earhart Project. Most words have many meanings ("freezing" for example) and the first step in communication is agreement about the meaning of the words we use. In the aviation world terms like "preservation", "restoration" and "original" have taken on quite different meanings than they carry in the traditional museum world. It's like the old joke - If you call a tail a leg, how many legs does a horse have? Four. Calling a tail a leg doesn't make it one. *************************************************************************** From Herman De Wulf Just in case anyone is interested in what happened to that Me-109G since, it is under repair (or should I say it's being restored ?), to be brought to static display standard. This had originally been planned. But having been stored for half a century in flying condition, it had been decided by the Imperial War Museum to bring it to airworthy standard before exhibiting it in the museum and let it fly at the Duxford airshow for ONE SEASON, just to prove it still flew. However, the rare airplane proved such a success and its engine is such fine condition that it was decided to let it fly ONE MORE but FINAL SEASON before putting it on static display for good. The RAF Vice Air Marshall who flew it on its LAST FLIGHT thought he had an engine problem when he saw smoke coming out of the exhaust and decided to get down as quickly as possible. As he was in downwind, he turned sharply, pushing the nose down in final. As we all know that causes an airplane to pick up speed and since an Me-109G was designed for speed, it needed all of the endless runway to throw off speed and settle. At the end of the runway it literally fell out of the sky, bounced over the fence and across the adjoining freeway, to land in a field across the road. Its conventional landing gear being incompatible with a potato field, the plane nosed over, landing on its back. Luckily there was no fire. From here on the preservation-mindedness of the British showed. The pilot refused to be saved from his precarious position by lifting the plane with a crane as this would... damage the plane. He insisted it be handled with great care. When it was eventually righted, the Vice Air Mashall climbed out, dusting off his flying suit. The Me-109G that survived a world war but was almost destroyed when flown in peacetime, is now under repair (or should I say under restoration, Ric ?). It is being brought to static display standard but will not fly again. ************************************************************************* From Ric In historic preservation terms "Black 6" (the Me-109G under discussion) is a "rehabilitation" and therefore not a historic property. That doesn't mean it's a piece of junk. It's an extremely rare aircraft, to be sure, and certainly worthy of attention and exhibition. "Repair" in the aviation maintenance sense of the word, is probably the correct way to describe what is being done to Black 6. The decison whether or not to fly the airplane once it's fixed is purely one of risk management. ************************************************************************** From Clyde Miller Stepping away from the issue of ownership etc. I would vote to preserve and display whatever large portions of the Electra survived in a near habitat diorama. Backdrop of the island, even a campsite reconstruction. Live crabs etc. Maps, pictures, artifacts, perhaps even the surf lapping onto the beach where the parts were discovered. Best of all TIGHAR expedition member cardboard cutouts peering from the jungle. Clyde Miller (who believes once a plane crash always a plane crash) *************************************************************************** From Ric RAF Hendon has just such an exhibit of what's left of a Hurricane found on a beach. Very evocative interpretation. The National Museum of Naval Aviation in Pensacola, Florida has an exhibit of an SBD and and F4F (as I recall) in as-found but stabilized condition. They're in a room intended to simulate an underwater environment. An exhibit of Electra wreckage would depend a lot on how much we find and where we find it. Having a full-size replica near-by seems like a good interpretive feature also. ************************************************************************** From Alan << I have not yet found a gentle way to point out that "fully restored" as used by the aviation community means "fully stripped of its historical integrity." This is a VERY difficult and emotional issue and there is tremendous potential for misunderstanding and shoot-the-messenger feelings. >> I well understand your point. For most of my adult life I have been intrigued by the Sopwith Camel. Periodically I would find a small plastic kit and build one. I have no idea where they went. I now have a flying model kit with about a 6' wingspan - still unbuilt unfortunately. I read everything I could about the plane. I talked to a WWI aircraft historian - self styled. He told me the flight characteristics (not all that safe) the numbering and markings. Then I found an old book describing Sopwith building the plane and turning the first one over to the RAF for a test flight at Aerodrome #1 in England. It was test flown on a day in 1917 by 2/t Alan K. Caldwell. (No, it wasn't me. I'm old but not that old) A few years ago I found there was one at Wright-Patterson Air Museum. I was really excited when I got there only to read the sign that it was totally remade from pictures, etc. It was never a real Camel. That plane now meant nothing to me. If I had come across a wreck in a field in France THAT would have been a real Camel. Alan L. Caldwell, not to be confused with............. *************************************************************************** From Ric But at least the sign told the truth about the exhibit. Many museums don't happen to mention that the airplane on display is not what it appears to be. As a general rule, the more information provided about "this particular airplane", the better the museum. The value of "living history" displays using rebuilds and replicas is illustrated by the Old Rhinebeck Aerodrome in Old Rhinebeck, NY. On any summer weekend you can watch a Sopwith Camel chase a Fokker DVII around the sky (plus performances by about a dozen other WWI vintage types). Of course, you're not watching "real" WWI airplanes but you're getting a visual, auditory, and olfactory approximation of what they were like. The buzz of rotary engines and the smell of burnt castor oil alone are worth the price of admission. ************************************************************************** From Dick Pingrey Ric, Yes, I can agree with your definitions but not fully with the purpose or perhaps it is the reasoning you state with those definitions. Museums serve the public in many ways and it is not just to preserve static history. They must entertain the public as well as educate them and preserve artifacts for them to study. Some times it is desirable to present an airplane as it looked and functioned the way it was at the time it was operational. That is also educational and it preserves an additional technology. The technology of how things work. When we destroy one of the few remaining ME-109s we have lost a major part of history but if we carefully repair a Piper Cub to original specifications and put it on display it does more to educate than the same airplane with fabric in shreds and parts falling off. After all these are hundreds of Piper Cubs still around. If that same Cub flies so people can see the technology of the 1930s in operation they learn more about our aviation history than if they only saw it as a static display. There is a balance in all this and it goes beyond just saving or preserving things as they are found. Dick Pingrey 908C *************************************************************************** From Ric You're getting into some interesting issues that go beyond the question of what does and does not constitute preservation. The first job of a museum is to preserve and exhibit relics of the past. Education is a secondary mission, but an important one. The Cub reconstruction you describe sounds like a valuable interpretive tool. Entertainment is also a necessary aspect of museum science because you have to get people to come see what you have. You're absolutely right about the need to seek a proper balance. In any museum there is always tension among preservation concerns, interpretation (education), and marketing. Volumes have been written on the subject. In some cases, most notably the Enola Gay fiasco at NASM, the conflict is played out on a national scale (and I'm already sorry I mentioned it). LTM, Ric ========================================================================= Date: Thu, 9 Dec 1999 13:09:07 EST From: Andrew McKenna Subject: Re: difference between preservation and maintenance Think of it as saving the artifact as found in the wild, like the Tyranosaur skull that is encased and crushed inside a large chunk of sandstone, and reconstructing the skull from the fragments, filling in the missing pieces with plastic, and putting braces on the teeth to make them look like they are "supposed to". One maintains its historical "in situ" significance, the other is still of historical interest, but is no longer "original" (although a whole lot more interesting to look at). A McKenna 1045C ************************************************************************** From Ric The re-assembled skull would be a "restoration" because it would "return the object to a known previous state through the minimal introduction of new material " (like maybe some plastic and some glue). This, of course, presumes that most of the skull is there and that the way an intact skull looks is "known." Such a restoration is, as you say, still historic (well, actually, prehistoric). But if you take a few skull fragments and reconstruct a whole skeleton and then cover it with styrofoam flesh and plastic hide you have a potentially educational exhibit, but it's not a dinosaur. ========================================================================= Date: Thu, 9 Dec 1999 18:47:58 EST From: Ric Gillespie Subject: New on the website A new Research Bulletin about the Lost Antenna is now up on the TIGHAR website at http://www.tighar.org/Projects/bulletin12_7_99.html and an expanded version of the summary of evidence recently posted to the forum is up as "The Next Step: TIGHAR's Earhart Project: Hypothesis and Plan".

There is some very good propagation analysis software available that can model a particular system and plug in the many variables (location, time of day, sun spot activity, etc.) and come up with information far better than an on-site experiment that would not be able to duplicate all that.

Uhhh, Ric, there are innumerable perfectly good historic buildings that have been rehabilitated and are still included in or eligible for the National Register of Historic Places; I'd certainly call them historic properties (as does the National Historic Preservation Act). When an airplane, or a boat, or a house, or anything else gets so changed that it stops being historic is an unresolved and probably irresoluble question, and any time we have to make decisions about how to treat a historic property we have to face real-world, practical questions about what's feasible, cost-effective, in the public interest, etc. Sometimes we do things that destroy the property's historic integrity because on balance, it's the best thing to do. Other times the balance gets struck someplace else. There just aren't any absolutes in the historic preservation business, however much some people would like it to be otherwise. LTM (who likes old stuff fine, but says change is inevitable) Tom King ************************************************************************* From Ric You and I have both struggled with the National Park Service's efforts to publish guidelines for nominating historic aviation properites to the National Register and it's like trying to drive a nail with a screwdriver. My comments were based on "The Secretary of the Interior's Standards for Historic Vessel Preservation Projects" published by the National Park Service (the same folks who run the National Register of Historic Places). It's the closest thing we have to guidelines that would be applicable to aviation preservation projects and it says (on page 12): "Regardless of their quality or use, and notwithstanding the degree to which they might serve the purposes of historic preservation, reconstructions, reproductions and conversions do not meet the criteria of the definition of a historic vessel." Some boats that have been made usable ("rehabilitated") retain enough of their original fabric to be considered historic, but returning an old airplane to airworthy condition necessarily entails the introduction of so much new material that it becomes a reconstruction and, therefore, no longer a "historic aircraft." You seem to be arguing for a fuzzy, politically correct, if-it-feels-right-do-it approach to historic preservation. I'd like to think that intelligent standards can be set and have been set (for vessels anyway), but you can't set standards of any kind without upsetting somebody. That's how we end up with high school graduates who can't find England on a map and museums that show us a shiny new 1918 airplane and tell us that it's "all original." LTM, Ric ========================================================================= Date: Fri, 10 Dec 1999 11:15:19 EST From: Vern Klein Subject: Fire Extinguisher For: Tom King Did Pyrene claim the Niku extinguisher as possibly their own? Did they indicate that they had ever made anything like it? I've looked at a lot of old fire extinguishers of various makes, and including a lot by Pyrene, on e-bay. The thing that seems to be unique about the Niku extinguisher is the nozzle end with what appears to be sort of a guard around the nozzle - a continuation of the outside diameter with what looks like three slots 120 degrees apart surrounding the nozzle protecting it and also making it possible for it to stand up on that end. At this point, I'm inclined to believe a particular handle shape is unique to Pyrene extinguishers. If this is valid, then the handle of the Niku extinguisher says, NOT Pyrene. I think we need to find an extinguisher with that kind of end, and perhaps that kind of handle, to identify its maker. Maybe that will lead to some idea of where it may have come from. ========================================================================= Date: Fri, 10 Dec 1999 11:57:28 EST From: Jim Razzi Subject: Re: Experimental communications Let me preface this by saying that it would be terrific if irrefutable proof were found that AE and FN landed on NIku. BUT, and at the risk of getting caught between a "kill the messenger" and the "Emperor's new clothes" syndrome, I don't understand how ruminations about antenna losses, or navigational errors, or fuel consumption could have anything to do WITH that proof other than leading to the "NIiku landing" theory which has already BEEN in place for years. ( ? ) Regards, Jim Razzi ************************************************************************* From Ric Good question - and I have a good answer. Although the "Niku landing" theory has been in place for years that doesn't mean that it's sacrosanct or frozen. It is under constant review and subject to amendment or total trashing at any time. We want to know everything we can learn about all aspects of the Earhart/Noonan flight and if, for example, new information about fuel consumption makes a compelling case that there is simply no way that the airplane could have reached Niku it will save us several hundred thousand dollars and a couple dozen bottles of sunblock not having to go back there. LTM, Ric ========================================================================= Date: Fri, 10 Dec 1999 12:17:41 EST From: Dennis McGee Subject: preservation I think both Tom King and Ric are correct (what did you expect from a guy who works in Washington D.C.?). If one plans to use the artifact, then it probably will not remain "original" because it needs to meet certain standards for safe use. If one plans to only display the artifact, then it probably will not be viewed too often because the public doesn't like looking at shabby, ratty, dirty "historic" artifacts. When I was a docent at the National Air and Space Museum's storage, restoration and presentation facility in Silver Hill (whew, what a mouthful) in the 1980s we had on display an unrestored "original" Spad XIII that still had unrepaired battle damage from World War I. The plane alleged was still in its original fabric covering with the original markings, which included linen patches (with an Iron Cross on them to signify enemy battle damage) covering approximately 20-25 bullet holes. However, when the NASM curators removed the plane's fabric covering they sometimes found patches where there were no bullet holes underneath. (Oops!) Also some of the holes that were covered by patches apparently were "inconsistent" with the ammunition used by either side during the conflict (anybody ever hear of a .30-caliber or 7.9 mm pencil?). They did find one hole in the structure of the horizontal stabilizer that apparently was the real McCoy. The last I saw the airplane it was in NASM's downtown WWI Gallery looking very "restored." The point is, if NASM displayed the airplane "as is" a great cry would rise from the masses to "do something," yet in meeting the demands of the public they have destroyed or degraded (depending upon your view point) the value of the artifact. It just goes to prove, you can't please 'em all. LTM, who has no battle damage Dennis O. McGee #0149CE ************************************************************************* From Ric It all comes down to education. Nobody complains that the ancient Greek pottery in the British Museum is chipped. In fact, if it wasn't people would say "Now wait a minute....". The common sense that it's okay and even manadatory that something old should look old somehow doesn't apply to air museums. The same person that would doubt the authenticity of a piece of pristine pottery will stand in front of "Smith IV" (the like-new Spad mentioned by Dennis) and say "Gee, an authentic WWI fighter." Go figure. It should also be said that preservation is not accomplished by neglect (which is how Smith IV got to the point where it was ready to just collapse in a heap on the floor). If you expect fragile material to last a long time you have to take very good care of it. It's called "conservation" and it's a huge part of museum science. LTM, Ric ========================================================================= Date: Fri, 10 Dec 1999 12:53:24 EST From: William Webster-Garman Subject: map comment, Noonan >>That's how we end up with high school graduates who can't find England >>on a map And, I might add, often don't even know how to read one. I enjoyed reading the new hypothesis page at http://www.tighar.org/Projects/AEhypothesis.html . When you have a moment, could you briefly elaborate why you believe Noonan might have died near the wreck site, and how his remains might have come to be buried on the western side of the island? william 2243 ************************************************************************** From Ric It goes like this. Assuming that he was there in the first place, he had to have died somewhere, and only one person's remains (most likely female) were found at the campsite even though there seems to have been part of a man's shoe there. Most likely explanation? Spare shoes salvaged from her dead partner. She could wear his but he couldn't wear hers. Other objects found at or near the campsite (Benedictine bottle and "corks with brass chains") seem to link the campsite person and, by definition the man's shoe, to the Norwich City survivors' camp which is near the putative landing site. Several independent anecdotal accounts describe bones found near the Norwich City wreck by the island's first settlers. After seeing the environment on that shoreline first hand, TIGHAR's forensic anthropologist Dr. Karen Burns feels strongly that unburied bones would not survive there for long at all. So whose bones were found? Possibly one or more of the three shipwreck casualties who were buried by their shipmates in 1929 and whose graves may have been uncovered by subsequent storms, or Noonan who may have been buried by his shipmate in the same area and similarly uncovered. Gallagher makes no mention of the bones found near the shipwreck so we must presume that he was unaware of them. We do have pretty good indications that what the settlers did with bones they came across is bury them, and there does seem to be at least one, and possibly a second, grave on that part of the island. LTM, Ric ========================================================================= Date: Fri, 10 Dec 1999 13:08:30 EST From: Greg Subject: Re: Experimental communications Better yet, seeing and doing rather than just thinking and surmising force an understanding at a different level. I offer the following as an example. In Europe it has been a part of the studies of prehistoric life to try to live in the habitat and with the tools and resources that are known to have existed. One item of study was copper in the use of axes. It was ASSUMED that the value of copper was minimal because it was so easily dulled but what was found when it was used in situ was that copper was also easy to sharpen and was very useful and much could be accomplished with it. \_ Greg _/ ************************************************************************** From Jim Razzi OK, good answer to good question received, Thanks.

LTM, Ric ========================================================================= Date: Fri, 10 Dec 1999 19:37:40 EST From: Ross Devitt Subject: Re: Experimental communications When I was in the RAAF, I trained as a radio tech. I used to know the formula for calculation the half and quarter wave lengths for different frequencies. This made it possible to string a plain wire antenna for anything, even a 27Mhz CB, which I think was 1/4 wave around 7 foot six inches, and 1/2 wave, around 15 foot. (roughly) There are bound to be a couple of "Hams" on this forum. If they calculate the wave length of 6210Khz and 3105Khz and 7???Khz, we can probably find the length of the antennas on the Electra (top of fuselage and bottom) nad divide into the wave length to see which is close to a 1/4 or 1/2 wave. Then you might know which one "fell off" as that is what seems to have happened. I would guess that the culprits were 6210 on top and 3105 on bottom. The length of wire has to be divisble into the wave length by 2 or 4 or 8 preferably. You may also find it is between the actual "posts" that hold the wire away from the fuselage, rather than the distance from where the wire comes our of the Fuselage. Sometimes the front bit is just for bracing the antenna mast against the slip stream, so there might be a few differnt calculations to do for the possibilities. From the pictures you have, and the plans for the Electra you should be able to find the distances involved. At the very least it may be just another technical detail "added" to the growing information base.

How are we doing with organizing them into understandable format? I am particularly interested in three at the moment. The "281" message is still gnawing at me! I should have kept a copy of it when Ric put it on the forum, but alas I didn't. Is it on the web somewhere? There was also a message that was supposedly picked up by the H.M.S. ACHILLES, which made them turn to the south and continue searching. Do you know what the bearing was of that message and it's content. The last one contains the phrase, "Can't hold with you much longer" Is the full text of that one somewhere on the site? Ric, thanks for putting Tom T. in touch with me. I think I understand now what you and Pat must be going through each day. How do you have time for the forum? The B-18 crew chief and I will be examining the artifact as soon as I get a copy. The Castle Air Museum is always willing to cooperate in my endeavors involving their aircraft. I am even allowed inside for pictures when necessary. I return the favor by keeping an eye out for usable parts from the wreck site I visit. If anybody needs any B-29 main landing gears for stocking stuffers, I can fix you up.

It contained fragmentary phrases in very badly sent morse code: 281 NORTH HOWLAND CALL KHAQQ BEYOND NORTH DON'T HOLD WITH US MUCH LONGER ABOVE WATER SHUT OFF Intriguing as this message is, preliminary results of the propagational analysis seem to indicate that it is nearly impossible for the message to have originated from Earhart's aircraft if it was on Gardner. The Achilles heard two stations talking to each other. One said, "If you hear us give us a few dashes." and the other replied with some dashes and then sent KHAQQ in code. The Achilles did no searching for Earhart.

Someone better tell the Mercedes museum. What about the prototype DeHavilland Mosquito which sits in Salisbury Hall in London, where it was built in 1940 as a wooden, unarmed bomber. It is the only prototype DH98 ever built, and flew with various engines and experimental loads and crashed heavily at least once, which unintention- ally demonstrated it could be repaired in the field. By the way, the DH98 type had the lowest casualty rate of any combat plane in WW2(highest number of sorties per loss) and the lowest fatalities per ton of delivered bombs. It was the fastest bomber of WW2, and successfully performed missions impossible by any other aircraft, such as flying in at 15 feet to pinpoint bomb the walls of the Amiens prison to release hundreds of resistance workers due to be executed. The yellow prototype serial W4050 that sits in Salisbury Hall in the "Mosquito Museum" set the DH98 level flight speed record of 437 mph at 29,000 feet using Merlin 77 engines and also set the DH98 altitude record of 40,000 feet with Merlin 61 engines. Now, to an Archaeologist's way of thinking, W4050 may not be preserved, but to my way of thinking it is probably the most interesting and fascinating single aircraft of WW2 extant, and is no reproduction. LTM(who likes the black DH98 airliner used to ferry spies), HAG 2201. *************************************************************************** From Ric It depends a lot on when the new fender was put on the Mercedes. The maintenance and modification issue that you raise is often a source of great confusion. Let me see if I can explain it. Any man-made tool (and airplanes, cars and boats are tools) undergoes maintenance and modification in the course of its service life. Most tools eventually reach a time when their usefulness in performing their intended purpose (in the case of an airplane - carrying people around the sky) is exhau sted and they get junked. However, in rare cases, the technology of the tool or some task the tool performed or someone's enthusiasm for that type of tool, give the tool a new purpose - that of a repository of information, or as a reminder of the task it performed or as a tribute to the people who used it and others tools of its type. That change in purpose from a machine used to carry people (and perhaps bombs) around the sky, to a device whose primary value is as a relic of the past, can occur at any time in an airplane's career. It might be a prototype retired after its first flight (the Hughes HK-1 "Spruce Goose") or after a long record-setting career (the DH98 you mention) or it might be a tattered wreck that is the last surving example of its type. No matter. Whatever the airplane is like at the moment the decision is made that the airpane is "historic", that is the "original" that the preservationist is starting with. So, you see, the DH98 is not a reproduction or reconstruction, it is an "original" of what it was when its purpose changed - unless, of course, somebody has decided to try to make it look like they think it once looked at some time in its storied past. Once the decision has been made to "save" a particular airplane, further decisions must be made about just what it is we're trying to save. If what we want is to keep the thing that was there at a particular moment in history either for sentimental or informational reasons, or both, then it's a no-brainer that we carefully safeguard whatever is there. If what we want is to recreate the look, and in some cases the feel and sound and smell of the past, then we throw away the stuff that is no longer attractive or safe or does not represent the time period we're trying to recreate and we replace it with new stuff or salvaged old stuff from other aircraft to create the illusion we're after. Both are legitimate ends and its always a judgement call as to what is the best way to deal with a particular old airplane (or car or boat or gun or you-name-it). The important is to recognize that we're making a choice and not think that we're doing one thing when we're dong something quite different.

Continuing the car thread on the question of originality. Are you familiar with the #2 Ferrari? The second Ferrari was built as a coupe, prototype for their first road cars. After not quite a year it was taken back to the factory to be rebodied as an open wheel racer to join the number 1 and 3 cars on the European circuit. While racing it suffered a serious "unintentional off track contact" (what the rest of us would call a crash). During rebuild the frame was replaced with a stronger stiffer item. Subsequently the engine and tranny were replaced with later components, newer wheels and brakes were installed, etc. Finally the old #2 car was retired to the company museum. Meanwhile back at the ranch. The original coupe body, after sitting in the works yard for some years was sold as scrap, and eventually wound up with a collector. He subsequently found the bent frame and the original motor. If memory serves he acquired a correct, but not original, transmission and differential etc. He repaired the damaged bits, bolted it all back together and now has a complete car. The question is, what car is it? Neither the coupe or racer have all original parts, but the coupe has far more original parts. On the other hand, the factories #2 car has had that identity continuously (and legally) for its entire existence. No easy answers. Robert Klaus ************************************************************************* From Ric Egad! The issue of "continuous identity" is an interesting one. The American warship "Constellation" is a case in point. She has been repaired so many times that there is now almost nothing left of the original ship but she has always been the Constellation. But if someone found the old timbers and cobbled together a ship, what would it be? I don't think it would the Constellation anymore than the re-assembled Ferrari coupe is the No. 2 Ferrari. Bizarre as it sounds, I think its a replica of the original using original parts. The underlying principle in all of this is that it is impossible to turn back the clock. ========================================================================= Date: Sat, 11 Dec 1999 17:44:12 EST From: Don Jordan Subject: Radio messages <> But did they take a bearing?

How sure are you that it's a fire extinguisher? Might it be some sort of hand operated pump? There's a pump in either case but is that possibly all it is? If what is taken to be the outlet nozzle is actually the intake, the extended outer diameter would allow it to rest on the bottom of a container witout blocking the inlet -- IF there's a slot. What is that light rectangle I see near the bottom end in the photo? It does look like there might be writing on it. Is that your own identifying label?? Hence, no slot(s)?? If it's a pump, then there has to be an outlet, presumably at the top - the handle end. I presume there is none such present. And I would certainly expect the handle to be in the center, if it's just a pump. Tom mentioned that the nossle is off-center. The handle appears to be off-center also - lined up with the nozzle, I presume. That seems odd. It would be easier to make with the pump in the center, the way Pyrene does it. The American penchant for simplicity - minimization? That makes it easier to form the end pieces. I see no good reason to place the pump part of a carbon-tet extinguisher off-center. To me, a concentric arrangement just seems natural. A curious, possibly unique, aspect of this artifact but I don't know what can be made of that. ************************************************************************** From Ric Worth thinking about.

Human beings can never be counted upon to react in a specific manner all of the time [even AE and our assumptions of her likely behaviour in a crisis]. And for witnesses in a cross-cultural setting [including with a local interpreter] when examined on matters of recall, particularly of what may be a seeming non-event or any significance in the past, any response - to register a high credibility rating - has to be balanced on the framing, environment and even the grammatical structure of the question posed; often down to the tonal and body language of the questioner. Having spoken to ni-Vanuatu in Espirito Santo in relation to missing WW-II P-38s, and who with willingness and politeness can still "read" and produce an answer desirable to the questioner. My observation and main query: Notwithstanding above, Emily Sikuli and Otiria O'Brian clearly have information nuggets and the closest as living witnesses to the mother lode. But has there ever been any similar active research to identify/locate members of the New Zealand Survey team of 1938/39? There is certainly corroborative value in the formality of the NZ report but the lights could really go on if an actual expedition member could be located and interviewed. LTM Peter Vincent ************************************************************************** From Ric Excellent observations Peter. We are very aware of the hazards inherent in gathering anecdotal accounts when we're interviewing folks. We even go so far as to lay little traps for them to see if they're "reading" us and just telling us what they believe we want to hear. We feel very good about the information we've gotten from the folks on Funafuti and in Fiji - not to say that what they told us is an accurate rendition of what happened, but that what they told us represents their best recollection of the events in question rather than their best guess of what we wanted to hear. We've been trying for some time now, with the help of several of our New Zealand members, to track down any surviving members of the survey party. So far, as luck would have it, the only one we've found is Henderson who got sick just as they arrived at the island and was evacuated immediately. Still looking.

I realize you do your best to make them as factual as possible, so there must be something I am missing. For example in the "Would the Electra Float" question. We have long thought that the Electra would float for a long period of time, if not indefinitely. As early as July 2, 1937 the "Experts" were saying the Electra is a floating raft with all those empty tanks. I read in the FAQ's that the empty weight of the aircraft was 7,000 lbs. and that it would be 1,200 lbs. buoyant. So far, so good. Then I turn to the Hawaii inventory list of parts shipped back to the states after the crash. It says the approximate weight of the damaged Electra and all of it's miscellaneous cargo, less fuel and oil is 14,114 lbs. estimated. They would not ship an airplane back full of fuel. I realize that some of that weight is packaging, but that is a hell of a long ways from 7,000 lbs.. What am I missing? It would seem to me that as soon as the air spaces in the fuselage were full of water, the Electra would sink like a stone. Maybe they were forgetting about all the non fuel and oil items on that airplane that day. So, do we know the weight of the aircraft on take off from Oakland? It would seem that we could do the math and subtract the weight of the fuel on board to arrive at a fairly accurate weight on July 2, 1937 at fuel exhaustion. Then we come to the "Did Amelia have an alternate plan" question. She, at one time said she would turn back to the Gilberts if she could not find Howland. She must have thought she could make it or she would not have said it. Also, as for not having enough fuel to return to the Gilberts. That depends on where she was when she made the decision. And that is what we don't know. If she was in fact on the 157/337 line which ran from Howland to Baker and Niku, then she would have had to be about 100 miles south of Baker. She said she was flying north and south on the line looking for an island and none appeared. (that we can prove). So she didn't go very far north on the line or she would have hit Baker! With an estimated three and a half hours fuel remaining at that point, then she could have just made Niku and not the Gilberts. But, what if she was on a direct course for Howland, but came up just 50 miles short. Then, she could just barely make Niku but would be in range of about three islands in the Gilberts. Arorae, Nikunau and Beru. It would have been a stretch, but she must have thought she could do it, or she would not have said it. Looking at the wall map it looks like the only land fall on the 157 course to the south is Niku. miss it by ten miles either side and you are all through! But the Gilberts are far more islands, closer together and almost all in a row. She would have a much better chance of land fall, I would think. The FAQ would lead you to believe that a turn back would be impossible. But I wonder if it would have been impossible. Don J. *************************************************************************** From Ric You raise a good point about the discrepancy between the aircraft's empty weight of 7,000 lbs. and the 14,114 lb. total weight of the material shipped back from Hawaii. A photo of the fuselage being slung aboard a ship shows that no huge crate was constructed around it. It's hard to see where all that extra weight came from. Figuring an accurate takeoff weight for the Lae departure is problematical because we don't know the effect of the many changes that were made in the airframe between the time of the Luke field crash and the second world flight attempt. Elgen Long says the empty airplane was 342 pounds lighter but he doesn't say how he arrived at that number and, if his other research is any indication, it's a meaningless guess. <> Well, no, not at all. Virtually every Earhart book you pick says that her final words were "We are running north and south" but the original Itasca radio log is not clear about what she said. What IS clear is that whatever she said caught the radio operator off-guard and he had to go back several minutes later and insert what he thought she said. What he crammed into the available space in the log can be interpreted as "We are running on north and south line" or "We are running on line north and south" but it's just as likely that she said something slightly different, perhaps. "We are running on line north to south." After considerable attmepts to find the original source, the whole turning-back-to-the-Gilberts thing appears to be pure folklore. There's no proof that Earhart ever said it and, if she did, it was not based upon the real life situation she faced when she was over the Pacific, and it was not Noonan talking. What makes following the line of postion make sense is that you don't need to know where you are on the line in order to find land. Just run to the southeast and you'll run into Howland, Baker or Gardner. Turning back to the Gilberts makes no sense unless you know exactly where you're starting from (in which case you're not lost in the first place). On your wall map the Gilbert's might look like a densely packed group of islands, but they're not. They're tiny atolls with vast stretches of empty ocean between them. A turn back to the Gilberts would not be impossible - merely suicidal.

To make a long story short......the scene where our hero has commandeered the German truck and is in the process of kicking his German passenger out of the vehicle, the camera pans clearly by, what looks like, our favorite fire extinguisher.

It's freeze-frame time. ========================================================================= Date: Mon, 13 Dec 1999 11:31:58 EST From: Dave Porter Subject: website updates/historic preservation Great job on the website updates. I encourage everyone who hasn't yet done so to check it out. I particularly like the instant links to documentation/supporting evidence. Pat deserves to be singled out for high honors for redoing the FAQ section. FAQs sorted, organized, grouped and presented by topic/heading. Outstanding job. Folks, the Earhart Project portion of the TIGHAR website is not the same site it was last week. It was great--now it's better than great. Tell your friends. Regarding historic preservation, Ric, since you mentioned it, and I have a teensy bit of expertise in the area, I'd like to elaborate very briefly on the historic preservation of firearms, hoping that doing so will help illuminate the overall preservation discussion. Most of the firearms on the Antique Arms Collector market just barely predate cars and airplanes, so some of the same problems arise. However, the sheer numbers of items in private hands does mean that the rules are rigidly adhered to because there is no other way to determine value when the items are bought/sold/traded/etc. Known manufacturer proof-marks and manufacturer letters of provenance and known dates of production for various batches of serial numbers establish what is or isn't original. Beyond that, condition dictates price. A beat-up specimen in original condition is worth far more than a pristine specimen that has been restored or modified. Thus, my uncle's Model 1873 Winchester, bought by his grandfather after it left the factory in 1891 (I have the letter of provenance) for about $15.00, which now has almost no bluing left on the metal, and no varnish at all remaining on the stocks, but still wears all the stuff it left the factory with, is worth something like $1,500.00. You can easily double that for one in better condition, and just as easily halve it for one that has been modified or restored. To get some idea of the value of the thing as a tool, a replica of current manufacture goes for about $300.00. Since the "market" for historic cars is considerably smaller, and is smaller yet for historic aircraft, the number of people who understand and wish to keep the historic value of artifacts by preserving them rather than restoring them is smaller. As I understand it, Ric and TIGHAR stand with that smaller, but historically more important group. While I know nothing of dollar values for old airplanes, I'd suspect that the relic in the Carrington wreck photo, if found somewhere and recovered, would be worth far more to historians than Linda Finch's modified 10A/E. If anyone wishes to discuss historic firearms, please contact me off-forum. LTM, who is still in original, unmodified condition. Dave Porter, 2288 ************************************************************************** From Ric Dave, thank you for that. I was aware that the historic firearms community is far, far ahead of the cars and planes community but I had never thought of sheer volume and market forces as the explanation. Unfortunately, while historians might value the airplane in the Wreck Photo, historians historically don't have any money. If that airplane were discovered today and looked just like it appears in the photo, it would probably be salvaged and rebuilt either for museum display or to be flown, or it might be parted out to supply "original" parts for other rebuild projects. Eventually it would end up just like Finch's airplane - a modern re-creation of an old type which incorporates some material that is original to its earlier service life.

Do we know it's a fire extinguisher of some sort, or just that it's an object that looks more like a fire extinguisher than anything else? The handle on top looks like it might belong to some sort of bug spray, which one might suppose a colonial outpost would be keen on. If it is an extinguisher, the size does suggest something for stowing in an enclosed space, eg aboard a plane. ltm, Phil Tanner 2276 ************************************************************************** From Ric No, we don't know for sure that it is a fire extinguisher but I tend to think that it's not a bug sprayer because there's no apparent way to refill the thing (unless maybe you emersed the bottom end in a bucket and just sucked it full by pulling on the handle).

They could continue for up to about 400 miles east if they overshot Howland, turn onto 157 and finish up smack in the middle of a collection of islands, mostly bigger than Howland. (For reasons shown below they didn't have to go that far). The fact that if they overshot Howland, continued on for a while and turned Due South They would also hit the islands was mentioned to me yesterday, HOWEVER, they would have to go a long way past Howland to do that. If they were South of Howland, when they thought they were at Howland's Longitude, and turned "left" to 337 or "right" to 157, they would still miss it or Nikumororo. So whatever happened, they could not reasonably be expected to turn to 337 unless they knew the distance they were south of Howland and the distance past (East). (If they knew that, they would have arrived exactly where they wanted.) On the other hand, turning to 157 "anywhere" that they could reasonably believe they were at or past Howland's longitude put them on either a direct track for Niku, or the shortest possible direct line to the other islands in the Phoenix group, thereby limiting the fuel wasted searching for the tiny Island. Howland is about a mile long and a half mile wide. According to CIA listings it is only 10 feet (3 metres) high at the one high point on the island. Most of the island averages about 3 feet high. (have heard Howland reported as 20 feet high - but everything I can find in print lists it as 3 metres). Niku and most of the other islands in what was the Phoenix group seem larger and would be easier to spot if one was flying around looking for somewhere to land. They would have to leave the vicinity of Howland with about 2 hours of fuel to allow them to fly towards Niku, locate it and land. From their last reports to Itasca, it sounds as if they might have done that in time... Ross D ========================================================================= Date: Mon, 13 Dec 1999 18:49:42 EST From: Herman De Wulf Subject: website updates/historic preservation Ric replied to Dave Porter : > National Fire Protection Association (NFPA), publishers of the National Electrical Code, the Life Safety Code, the Fire Prevention Code, the National Fuel Gas Code, and the National Fire Alarm Code. The mission of NFPA, which was organized in 1896, is to reduce the worldwide burden of fire and other hazards on the quality of life by providing and advocating scientifically-based consensus codes and standards, research, training, and education. The Massachusetts/Call Volunteer Firefighters Assn have a bulletin board related to rare and antique Fire Extinguishers. http://www.mcvfa.org/wwwboard/messages/842.html Is there a picture of this "fire extinguisher/thermos bottle"? I missed the start of the thread, but it sounds like a fire extinguisher was found on Niku. I know the one on Earhart's aircraft was one quart, but what is the capacity of the one you found? Ross D ************************************************************************* From Ric Read all about it and see the pictures at http://www.tighar.org/Projects/bulletin11_28_99.html Since that bulletin was posted we have determined (actually Jeff Glickman at Photek has determined) that the object found on Niku is not the same as the object seen in the photo of AE and Noonan loading the Electra. The object found on Niku is probably a fire extinguisher. The object about to be loaded aboard NR16020 is probably a thermos bottle. We haven't determined the capacity of the Artifact 2-4-V-100 but a quart and a half seems about right.

RossD ************************************************************************** From Ric A few nights after the disappearance, when Itasca was searching far to the northwest of Howland, lights were seen in the sky that were at first taken to be flares but were later determined to be a meteor shower. Nobody knows whether there were flares aboard the aircraft for the Lae/Howland flight, but the kind of flares the Electra carried were flares intended for dropping from the aircraft to illuminate the ground for a night landing.

What information did AE/FN have regarding the habitability of the islands of the Phoenix Chain, for instance, did they know that Hull Island _was_ inhabited & that Gardner Island was _not_ inhabited? Seems unlikely that AE would have had such knowledge (unless she had established an alternate landfall before the flight & made some pre-flight inquiries regarding habitation of the Phoenix Chain islands or FN still had some recollection of these islands from his Pacific charting days with PanAm). Since AE/FN had no prior knowledge that their disappearance would touch-off the greatest air/sea search in history (until that time), it would seem that their only anticipation of being found & rescued (should they _miss_ Howland) rested with being able to somehow establish reliable radio communication with the Itaska. The thought must have occurred to AE/FN that the possibility of establishing reliable radio contact with Itaska (given their unsuccessful efforts _in the vicinity_ of Howland) would probably _diminish_ the further away from Howland Island they flew. Their dilemma: 1) Ditch the plane, in what they perceived to be the immediate vicinity of Howland & trust that the Itaska would launch a search for them in the waters in the general area surrounding the island; 2) Try to determine an accurate course (not knowing exactly where they are on the LOP FN had established) to turn back to the Gilberts (which they knew _were_ inhabited, with the possibility of finding a radio available they could use to try & establish contact with Itaska ) & probably have to ditch anyway when they ran out of gas short of landfall, but hopefully close enough to be picked-up by island inhabitants; 3) Turn SE on the lower leg of the LOP toward the Phoenix Chain (a more certain target, directly on the LOP, than trying to ded reckon a course to the Gilberts, from an unknown position on the LOP) which is several hundred miles closer to Howland than the Gilberts, with the _possibility_ of making a wheels down landing & then using their own radio to try & contact Itaska, even though they have no sure knowledge that they could long survive on an uninhabited, isolated island; when they really aren't sure there are any other inhabited islands close enough to assist them in any rescue attempt or any radio equipment that could be used to let Itaska (and the rest of the world) know they had survived. Given these choices, I'm thankful that such a decision wasn't left-up to me! Don Neumann ************************************************************************** From Ric It's actually possible to make the argument that Earhart and Noonan considered landing the Electra at sea to be so suicidal that they intended to evacuate the airplane in flight rather than ditch, should the occasion arise. The evidence for that is the fact that a contemporaneous Darwin, Australia newspaper article says that (contrary to what was later published in the heavily-edited book "Last Flight") Earhart and Noonan picked up two parachutes that had been shipped ahead to Darwin. Why fly two thirds of the way around the world without parachutes only to collect them prior to the long overwater legs unless you felt that a water landing was out of the question? LTM, Ric ========================================================================= Date: Tue, 14 Dec 1999 18:20:26 EST From: Ross Devitt Subject: Re: flares It is the gun I was referring to. The flare gun (and one round of ammunition) is on the Luke Field Inventory. Obviously, (when?) they landed on Gardner, there are certain things they should have brought ashore. Water and food (we know the aircraft had survival rations, at least at Luke Field) and the flare gun and flares. It seems odd that I can only find one flare listed, but that's all I can see. It would seem very strange for an aviator to leave behind that basic survival aid. (But then anectdotally, AE & FN did a few strange things). I'm trying to think of obvious "metallic" things that should turn up on the shore other than buttons & cloth. Finding something as small as an eyelet was great though. We know there is an inverting eyepiece sonewhere. That will be at least an inch or so of metal & glass. It is also strange in itself. The eyepiece is used to flip the sextant image so it is "more natural" to look at (a sextant as you know will show the imabe upside down). An experienced navigator probably wouldn't bother using it, hence finding it with the box. So where is the sextant. No navigator would keep such a valuable instrument out of its box... So many enigmas.... So there it is. I believe you are going to find a sextant laying around there somewhere. And it will be the "personal" backup one, not the Electra's one. FN would have brought his "old faithful" ashore if he brought one...

Given the distances flown, and that most aviators then tried to carry a flask of hot coffee (or tea if British?) four flasks of hot coffee may be a sensible assumption. The back one however has a wider neck. In the old days when we had metal flaskt (mostly Thermos or Stanley brand) there were several neck sizes. The wide one was commonly used for hot "food" like a good stew. The middle size for soups etc., and the smallest for coffee or tea only. The theory being that the smaller the opening the less heat escaped each time you opened it. As all four objects have cups on top (over the opening) I wonder where the idea one of them might be a fire extinguisher came from??

Having worked with several major exhibitions in the US, including Napoleon, Imperial Tombs of China, Titanic, etc. I have learned something important. There will always be some jackass who knows the price of everything and the value of nothing. For instance, during the Napoleon exhibition we had a portion of the jewelry he bestowed on his women. As I would walk through the galleries checking on this or that, someone, at least once a day, would stop me and ask me the value of a certain diamond necklace that was on loan from the Smithsonian. It rounded out at about 200+ carats. I would respond "It is priceless." and they would always say, "Yes, but what is it really worth?". And I would explain the historical value of the piece and how it could never be replaced, etc. And still, "Yes, but how much is it worth?". By this time I was wondering about the future of the human race. So I just made up a figure and they were happy and went on their way. (How frightning these people are loose!) 2.) I am currently working in a regional history museum and I have plenty of school age children. They are fascinated by unrestored, original equipment ONLY as long as they can associate it to a major historical event. For instance, we have a Conestoga wagon that is 160 years old. The ancestors of the family who loaned the piece traveled in this wagon from South Carolina to settle in Tennessee. Kids are mesmerised by this wagon. But yet, the pieces we have from everyday life have no interest to these children. On explaining the mechanics of a rope bed, a child was overheard to say, "why didn't they just get a new one?". Further on, we have some Civil War muskets and clothing and let me tell you, I have to pry those kids off that glass with a scraper. What am I trying to say? I am trying to say that the public is very finicky about historical objects. TIGHARs do not represent the majority of the public (unfortunatly). Once you get out among the hordes it can be very surprising at how selective the interest of the public is as to how authentic an artifact may be. Some will admire at face value while others must have a dollar amount. Yet others will only be interested in an artifact if it is connected to major event with which they are familiar. You would be amazed at some of the things I have heard in museums over time. Just last week a nine-year-old boy tried to buy an artifact off me. He could not understand it was priceless and not for sale. He said, "Everything has a price." How frightening this is for the future. LTM (who knows the value of everything) MStill the head TIGHAR's #1 fan. ************************************************************************ From Ric Fascinating subject. It seems to me that all historic preservation relies upon the informed observer understanding the connection an object has to PEOPLE. Objects are not interesting. Only people are interesting. Dead people go away and never return. Objects don't necessarily go away and, thus, provide us with a visible, tangible link to people who are irretrievably gone. The Great Pyramid is just a pile of cut stones until you know something about the people who built it. The folks who insist upon knowing the monetary value of an object are, for whatever reason, unable to make that connection or simply have no interest in the people of the past. They seek to connect the object to themselves by putting it in a context they understand - money - but the concept is the same. The object must be connected to a person in order to have value. Original objects which show the effects of time provide the strongest sense of connection to the people of the past. They stand in defiance of the mortality we all face and say, "Yes, they are gone, but I am still here to tell you about them." Other objects have been repaired and rebuilt so that they appear to deny rather than defy "the teeth of time." Like Peter Pan, they take us to a nostalgic Never Never Land, and like Peter, they are necessarily works of fiction. Ideally, we should all be able to enjoy and recognize the value of both of these manifestations of our desire to expand our experience beyond our own alotted time and connect with those who have gone before. (Ya know, that's the first time I've been able to articulate that. Thanks.)

Okay Ric, so are you fairly sure that they had these 'chutes on the Lae-Howland leg, and if so, what would be left of them to find on Niku today? Do you know if they were organic (silk) or synthetic (nylon, though I don't think this came into widespread use until a few years later), and if we do know what they were made of, how would they have 'aged' in the tropical climate? What about the buckles, etc. - if they were stainless steel, they might be around in good shape, but would they have serial numbers stamped into them? Have any attempts been made to trace the manufacturer of these rigs? ...since parachutes generally do have serial numbers and a paper trail. Also, do you know if AE/FN had taken any training in using these devices, since body position in freefall does make a big difference. LTM, (Who only cares that her 'chute works when required!) David :-) ****************************************************************************** From Ric Well, first let's be clear that we don't know that the 'chutes were carried on the Lae/Howland leg. We can be quite sure that they were picked up in Darwin because the newspaper article says they were there waiting for her and we have a photo of them, and some other stuff, stacked in front of the Electra's cabin door in Darwin. Here's the passage from the June 28, 1937 article: (describing the flight's arrival at Darwin) ** Although Capt. Noonan appeared to be little affected by the long flight, Mrs. Putnam looked tired when she appeared smilingly before the crowd. She was hurried away to a quiet room in the civil aviation administrative block to discuss with her agents the arrangements for her short stay. One of her first actions was to ask the Civil Aviation Officer (Mr. Alan Collins) whether two "Irvin caterpillar 'chutes'" had been delivered from America. Fully tested and ready for immediate use, the parachutes were waiting in Mr. Collin's office. As a safeguard against emergency, they will be carried on the hazardous final stages of the flight. ** Unless I am very mistaken, a parachute in 1937 was absolutely silk and was probably packed in a cotton pack. Such organic materials have a short life on Niku, but - as you say - the buckles, especially if they were stainless - might well survive IF the 'chutes made it to shore. I certainly would have brought the 'chutes ashore for use as shelter (but remember that AE and FN were not expecting an aerial search so spreading out a parachute as a signal doesn't make much sense). IF they brought the 'chutes along on the Lae/Howland leg and IF they brought the 'chutes ashore and IF they used them to construct some kind of shelter from the sun, could these be the "markers of some kind" that Lambrecht later told Goerner were the "signs of recent habitation'" he had referred to in his newsletter article? At the very least, this whole bit about the parachutes is yet another example of how original sources directly contradict events described in Earhart's posthumously-published book "Last Flight."

Back in 1989 during our first trip to Niku we came across a big ol' safe in the remains of the Government Station. It was locked, or at least rusted firmly shut (no way to tell which). Now, bear in mind that the island had been abandoned in a very orderly manner and it is hardly surprising that a several hundred pound safe did not get taken along. It would also be extraordinary if anything of any interest or value was left behind in the safe. But the very fact that it was an unopened safe drove some of our, shall we say - more imaginative - team members absolutely nuts. Tom and I found ourselves constantly saying, "No, we're not going to open the stupid safe. It would cost at least half a day to cart the tanks and equipment for a cutting torch all the way to where the safe is, cut the thing open, and lug the equipment all the way back to the ship. The hypothesis that the safe contains something important is not sufficiently supportable to justify the cost of testing it." The safe remained closed. As I recall, on a subsequent visit ( I forget which) we noticed that the safe had rusted though. The was nothing inside.

These instruments were made of brass & aluminum & could quite possibly survive all these years because when they were not in use, they would be packed in a wood storage case that was well made from a finished hardwood. I have several in my collection that are vintage WWII era and none have had corrosion. Granted they were not usually sitting in a salt air enviornment, but up until the late 1960's they used a lubricant derived from whale oil. I still find smears of this lubricant when I add another to my collection. It tends to gum up over time but it also kept I believe corosion away. If Fred took care of his equipment this way, I think some beach combing & a metal detector could possibly find these tools of his trade. I do not know if the beachcombing w/ metal detectors technique had been done on previous expeditions. Any comments Ric? Doug B. *************************************************************************** From Ric Some sections of beach have been metal detected extensively. Others (read most) not at all. Niku has about 10 miles of beach which ranges from about 100 to 200 feet in width. One person with a metal detector can thoroughly search perhaps 100 feet of beach in an hour, not counting digging the hits.

Unless the sextant and box belonged to the Master of the Norwich City. I think that's unlikely however as a sextant was a VERY expensive (and a brass one still is) piece of treasured equipment, and there's no way the master of a ship would leave the sextant or even its box and an eyepiece (that is more commonly used in the air) lying around in the scrub.

None the less, a wheels down landing on Terra Firma would always seem more acceptable than ditching in the ocean! Don Neumann ************************************************************************* From Ric The closest AE ever came to making a parachute jump, as far as I know, was a publicty stunt she did on a parachute tower that Putnam was involved in marketing as an amusement park ride. I would be very suprised if she ever made an actual jump. Amelia's thrill seeking did not run to physical sensations. She was a very conservative pilot and reportedly did not even care for steep banks, let alone aerobatics. Likewise, I can't imagine where Noonan might have gotten any parachute training. That said, I've never made a parachute jump but I've worn a 'chute many, many times. For evacuation purposes there's not much of a learning curve. Jump out, count to ten, pull the handle, change your underwear. LTM, Ric ========================================================================= Date: Wed, 15 Dec 1999 13:06:50 EST From: Alan Caldwell Subject: Re: FAQs - The significance of 337 - 157 << If they were South of Howland, when they thought they were at Howland's Longitude, and turned "left" to 337 or "right" to 157, they would still miss it or Nikumororo. So whatever happened, they could not reasonably be expected to turn to 337 unless they knew the distance they were south of Howland and the distance past (East). >> I've seen several comments similar to this one which leads me to believe the LOP is not fully understood by all. Noonan did NOT need to know whether he was north, south, east or west of Howland to turn in either direction on the LOP to correctly over fly Howland or navigate on to the Phoenix group. It would have made the choice much easier and if he turned in the correct direction he could not miss Howland or the Phoenix except by visually missing them. Let me explain how the LOP is made and used. For sake of argument and referring to the diagram below let's assume Fred was around 200 miles west of Howland and flying a course (a) of due east. (so my drawing below will come out) Fred shoots a 2 minute sunshot giving him the altitude of the sun and its azimuth. In this case 67 degrees of azimuth. Using that information he plots his LOP (1) angled across his course. He knows now that he was on that line some place at the mid time of the shot. Ten minutes later he takes another sun shot and again plots the LOP (2) angling across course. Using the distance between the two LOPs and the time between them he now has his ground speed in addition to a new position. Next he draws a line parallel to the first two lines so that it will pass through Howland Island (LOP 3). Now he measures the distance between the second LOP and the line running through Howland and applying his ground speed to that distance he arrives at an estimated time to the Howland LOP. He still does not necessarily know where on the line he is. Now let's say he believes he is north of Howland so on his ETE he will turn right to 157 corrected for what he believes is his wind from the ground speed calculation. He will have Amelia lead the turn onto the LOP by a number of seconds calculated using her rate of turn indicator (turn and bank) and the number of degrees to turn. Perhaps ten minutes later Fred will take another sun shot which will NOW tell him whether he is drifting right or left of his LOP course. He now has a good wind to navigate by but still no north -- south position -- maybe. If Fred thought he was south of Howland he would do exactly the same thing. Remember the LOPs are all parallel so again when his ETE arrives he has Amelia start her turn and again leading the turn but this time left to 337. When his ETE comes up he is ON the 157-337 LOP that goes through Howland no matter WHERE on the line he contacts it. In either case he has only two problems. One, where he is on the line and two, visually spotting Howland. As to knowing where he was on the LOP he could know that because he offset his course either north (b) or south (c) on the way in or because he also shot a moon shot to cross an LOP with his sun LOP or because he shot a running LOP on the way in. The running LOP takes into account the sun's azimuth changes over time thus making a subsequent LOP at a slightly different angle. By moving an old LOP up to the newest one the LOPs would cross at a very narrow angle and give him a rough idea of his position. The timing involved in doing a running fix leads me to believe there was insufficient time to do that in the approximately two hours from sunrise to his last radio call. The bottom line is that Noonan had to know he was on an LOP that ran through Howland and they were ON that line unless he was unable to get a ground speed as noted below. He had the capability of fixing his position north and south and knowing reasonably how far they were north or south. I think they just flat could not see the island visually. 1 2 3 b __\ _____________ \ ___________________________\ \ \ \ a____ \_____________ \____________________________\*_Howland______ \ \ \ c______\ _____________\ ____________________________\ \ \ \ LOP LOP LOP (157-337) As you can see in the diagram above the distances between LOPs are the same no matter whether they were on course (a) north of course (b) or south of course (c). For the sake of explanation assume LOP 1 was taken at 6:30am and LOP 2 was taken at 6:40am and the distance between the two is 20nm. That gives a ground speed of 120k. Now Fred draws LOP 3 through Howland and measures the distance between LOP 3 and LOP 2. Let's say the distance is 120nm so he now knows he will hit the LOP 3 some place in one hour or at 7:40am. It is at that time (less turning time) he has Amelia start her turn to 157 or 337. The point is that getting on the LOP 3 passing through Howland was simple and I can think of no reason he wasn't on it. He had to be able to shoot the sun or he couldn't have obtained the 157-337 LOP. There remains the question of whether he could figure his north south position. If he could see the sun he could see the moon. It was up and at a good cross angle. That would give him a fair fix. It is also possible, of course, that because of weather he was only able to get one sunshot and so had to "guesstimate" his ground speed and thus his ETE to the LOP through Howland would not necessarily be all that accurate. I hope this was clearer to you guys than it appears to me after I have reread it. One caveat here is that I have over simplified the procedures by leaving out all the DR figuring but the explanation still holds.

The biggest risk would be getting smacked by the tail. Why jump? It's all a question of percieved comparative risk. If I was flying an airplane at night in instrument conditions over rugged terrain and i had an engine failure or ran out of gas, you better believe I'd bail out rather than ride it down if I had the option. Linda Finch expressed profound concern about the prospect of having to ditch her Electra. The nose and cockpit section are so lightly constructed that they might be expected to crush, trapping the occupants as the airplane sank. Of course, theres no way for us to know just why AE and FN wanted those parachutes, but it does seem to be the case that they wanted them. LTM, Ric ========================================================================= Date: Wed, 15 Dec 1999 13:40:42 EST From: Patrick Gaston Subject: Gilberts and Gilbeys (?) The Dons (Jordan and Neumann) echo my thoughts. While charting a course for Niku may have made the most sense from a strictly navigational standpoint, there were other factors to be considered. -- specifically, people and water. The Gilberts had both and Gardner had neither. Let's not forget that nobody knows precisely where Our Heroes were when they turned right or left on that line of position. Was a turnback to the Gilberts >>necessarily<< suicidal? No, since AE could just as easily have been 100 miles north of Howland as 100 miles south. Was it worth the risk? Only if you think your chances of rescue are greater in an environment containing actual human beings. In any event, I for one am unwilling to dismiss the puported "Gilberts backup plan" as Earhart folklore until the Vidal papers have been searched box by box and page by page. Speaking of folklore, I am reminded of what was said about U.S. Grant, another Famous Alleged Drunk, by one of his contemporaries: Grant didn't drink any more than anybody else in the Army, so the story went. He just couldn't hold it. Which got me to wondering about Fred Noonan. Is it possible that Fred didn't drink more than anybody else, but simply ran afoul of a Boss Lady who disapproved of alcohol in ANY form? Certainly AE had an alcoholic parent, and she seems to have become less tolerant of the stuff as the years went by (going so far, I believe, as to ban it from her California home). We know that on at least two occasions during the last flight, AE complained of "personnel problems" and "personnel unfitness." This has entered Earhart lore as code for Fred's On The Sauce Again. Still, it is difficult to reconcile these complaints with Fred's cheery, upbeat letters from enroute (copiously quoted in "East to the Dawn") and the chipper Noonan who fairly sprints up the Electra's wing in the Lae takeoff film. This is a guy who was supposedly getting blind drunk on a regular basis? One wonders if Fred was no more than a social drinker (by the standards of his day), while AE, freethinker and pioneering feminist, was just a bit of a bluenose in the alcohol department. Ric, any chance of making available in CD form the NZ Survey Report and all 78 photos, together with all of Bevington's and Maude's Niku diaries and photos? Perhaps you could even get permission from Maude's publisher to excerpt relevant chapters from "Of Islands and Men." I dunno if I'd pay $100 for it, but maybe 25.... Patrick Gaston ************************************************************************** From Ric We just don't seem to able to get across why it is that following the LOP was greatly preferable to turning back to the Gilberts. Perhaps William Webster-Garman's recent posting will have more success than have my meager efforts. I can think of no reason why Earhart or Noonan would have had any better information about the population situation in the Phoenix Group than did the U.S. Navy. If they turned back for the Gilberts, for whatever reason, it seems pretty certain that they went down at sea because (as you point out) the Gilberts were densely populated. It's a possibility, but like every other possibility we can think of except a landing at Gardner, there is a rather impressive absence of evidence to support it. LTM, Ric ========================================================================= Date: Wed, 15 Dec 1999 13:44:46 EST From: Mike Meunich Subject: Re: fire extinguisher I have reviewed my oldest source, 12th edition, 1962 volumn of the fire protection handbook to look for similar units. The handbook is not an exhaustive reference, quite the opposite, but it does have a section on portable fire extenguishers, (18) and there are some photographs. The photo on the Web site does not reveal in detail the arrangement on the "top" of the unit. There appears to be a handle on the "top" with some type of orifice that lines up with the stem of the handle. I assume that a shadow of the handle appears on some type of backdrop. I think it would be unusual for the handle to located so near to what has been referred to as a "nozzel". Anyone carrying the unit would be subjected to the contents of an accidental discharge and if the "handle" is actually an activating device, the operator couldn't "point and shoot" the unit and control the flow simultaneously. But for the "plumbing"and some additional piping, there is a photograph of a unit on page 18-36 of the handbook which depicts as very similar extinguisher. I don't have a scanner, but would fax a copy of the photo if you like. The handle is actually a pump handle or control valve and what has been referred to as a "nozzel" is actually a nipple to which a hose is connected. The base of the unit on the Web site and the photo is flat and is designed to stand on a floor or flat surface allowing the operator to actuate the handle and direct the agent through the hose in a "point and shoot" method through a nozzel on the end of the hose. The photo has a classification plate located exactly where the classification plate seems to have been on the unit on the Web site, assuming it is, in fact, an extinguisher. The unit depicted in the handbook is a vaporizing liquied extinguisher, usually a specially treated form of carbon tetrachloride or chloro-bromomethane. When the liguid stream was directed as the base of a fire, the liquid rapidly evaporated and formed a smothering vapor blanket. This type was effective on both Class B (liquid hydrocarbons) and Class C (electrical) fires. It was not effective on Class A (ordinary combustibles such as wood or papar) fires, thus would have been suitable for the AE mission. The handbook indicates four types of pressure units and one type of pump unit within this catagory of extinguishers ranging in capacity from one quart to 3 and 1/2 gallons. Pressure units are pre-charged with Carbon Dioxide, Nitrogen, or medium pressure air. The other type is literally a manually operated pump. Examination of the unit should reveal the method of actuating, charging, discharging etc if it is, in fact, an extinguisher. ************************************************************************** From Ric Thanks Mike.

Lincoln was quoted as saying, "I can't give up this man. He fights!". Only when his drinking began to run to the excess did Lincoln become concerned.

Of course if the sun and moon could both be shot, he'd have two sides of the triangle and be very close to a North / South fix. FN was a very experienced navigator with considerable over water experience. I think I previously mentioned a technique used some years earlier by Sir Francis Chichester on solo over water flights. Don't try to find a "speck in the ocean", aim for a position to one side of it and turn towards it when you reach the line it should be on. The point I'm trying to suggest is: 1 Noonan would have known of Chichester's methods as they had been used by other aviators. 2 If (and only If) Noonan used a similar technique, would he aim for the Southern side of the probable position, or the Northern side where turning in a Southerly direction would at least give him optional islands if he missed Howland.

Ric wrote, "We just don't seem to able to get across why it is that following the LOP was greatly preferable to turning back to the Gilberts." Because Ric, most of us don't believe she was on the LOP which ran down the middle of Howland, Baker and on to Niku. Think about it for a minute. She said she was running north and south on the line. That means maybe thirty or forty miles north and then maybe a hundred miles south, or visa versa. To have Noonan be on that line he would have to be pretty damn far off course north or south but not east or west. In other words, he figured the head/tail wind perfectly, but forgot the cross wind component. If he were north of Howland, they would have seen it when the turned south. If they were south of Howland, they would have seen Baker when they turned north. The only way they could have been on that line and miss Baker or Howland would be if they hit the line almost one hundred miles south of Howland. I don't think Fred was that drunk! But what if they did hit the line a hundred miles south, do you think they would say to themselves, "Well. . . Howland is not here. I don't think we know where we are, so let go south for three hours and see what's down there" In my opinion, they simply could not have been on the Howland LOP and not found Baker at least. With maybe four hours fuel left, they could have almost gone to Niku and back. Don J. ************************************************************************* From Ric This is like Miranda.

I am coming around to the idea that Fred had enough confidence in his ability that he may well have navigated straight to Howland. I'm not seeing any evidence yet that he offset. I don't think he needed to if he had any decent star, sun and moon shots. I am not convinced he was expecting a good DF on arrival but the mere fact Amelia called for one lends support that they DID in fact expect a DF steer. The report they were running north and south (IF that is accurate) is still not troubling. I had enough confidence in our celestial navigation to go direct and not offset. We DID have an LOP through destination and running back and forth over a short distance was not a problem. Admittedly we had radar and Vortacs but on exercise only celestial and DR could be used.

You guys have already gone through this I suppose but I have checked historical weather data from the Pacific and little is available from the Phoenix area but that may well be because it is out of the beaten path for heavy duty storms. I would imagine Niku has been hit hard a few times since 1937 but I can't support that yet. Alan ************************************************************************** From Ric I can. For example: First week of January 1939 - the New Zealand survey party experienced "exceptional westerly swells" which resulted in tides that were "4 feet above the ordinary spring tides of December 6th." November/December 1940 - Gallagher reported "severe and almost continous North-Northwesterly gales" which did considerable damage to the newly established colony. Sometime between when we left the island in October 1989 and returned in September 1991, severe westerly weather had taken out a massive concrete and rebar beacon high on the beach which had marked the landing channel. About 50 feet worth of beachfront vegetation was piled like cordwood against large trees inland, and the seaward side wall of the Co-Op Store (well back off the beach) had been knocked down by waves. And then there was 1997 when we cleverly managed to be there for some westerly weather. I don't want to talk about it. LTM, Ric ========================================================================= Date: Thu, 16 Dec 1999 10:14:41 EST From: Dustymiss Subject: Re: parachutes Because you have never heard of Amelia making a parachute jump, only means that she never had to exit a disabled aircraft while in the air. In those days it was not necessary to take training in jumping, as far as I know, it was just necessary to have one while flying, and if you had to jump. It was on the job training as far as how to use it. At least that is how it seemed when I heard Fay Gillis Wells talk about the time she was forced to jump back in the late twenties(I believe - or very early thirties) To the best of my knowledge, Amelia was not a member of the Caterpillar club, but it was SOP to carry a parachute any time you were flying in the late 20's and into the thirties - So, I am certain that she was familiar with having to wear one, even though she may never have had to use it. Some examples are Marvel Crossen who jumped out of her damaged aircraft during the 1929 Air Derby, with parachute; Fay Gillis Wells who became the first woman to join the Caterpillar Club and Charles Lindbergh, if I am not mistaken jumped with one in the story where the plane followed him because he forgot to cut the engine before jumping. Plus, as you recall, in the information I got from the University of Wyoming, while doing the research on Gene Vidal and a potential plan B that there was a newspaper article about Amelia being the first woman to test a stationary parachute jump platform. The photo that accompanied the story shows her in the air, under canopy. If you wish, I shall endeavour to find out from Fay Gillis Wells if she ever remembers Amelia jumping, the next time I speak with her. ************************************************************************* From Ric Yes, that would be interesting, but I have to take issue with your impression that pilots routinely carried parachutes during the '20s and '30s. Military and airmail pilots routinely wore parachutes, but airline and general aviation pilots did not. Earhart wore a 'chute when flying the Pitcairn autogiro in 1931 and seems to have carried a seat pack on at least some of her long distance flights in her various Vegas. There's a photo of her wearing a parachute (actually, just the harness for attaching to a seat pack) taken immediately after the completion of her Mexico City to Newark, NJ record flight in 1935. That long crossing of the Gulf of Mexico in her single engined Vega is supposedly where she got the idea that it would be much better to do overwater flights in a multi-engined airplane. As you've noted, AE was not a member of the Caterpillar Club (Lindbergh set an unenvied record as a triple member) and in those days "sport" parachuting was limited to exhibitions at fairs and airshows. Amelia's supposed testing of a stationary parachute jump platform was a publicity stunt staged by GP. He was involved in a venture to market the towers as amusement park rides and military training aids. One tower ended up at Coney Island and another at Camp Benning, Georgia. Amelia's "test" was the subject of a newsreel. She sits in a swing-like seat and is hoisted to the top of the tower. When the 'chute reaches the top it drops a few feet before inflating and Amelia screams (it's not clear whether the sceam was real or dubbed in later). In summary, Earhart was certainly familiar with parachutes but there is no evidence that she had ever made a parachute jump. LTM, Ric ========================================================================= Date: Thu, 16 Dec 1999 10:39:41 EST From: Dana Sibilisky Subject: on parachuting lets remember the adage, for those of us who fly, 'any landing you can walk away from, is a good landing'. I find it impossible to believe, with 5 hours of fuel remaining, albeit an exhausted crew, still an experienced one, AE and FN are trying to find this fly speck of an island. After trying for a few hours, they had to be thinking of the alternatives. One of them had to have known something about the other islands, if nothing more than that they could look out the window and see a few, simple pilotage. I'm sure three things came to mind, first AE is looking for enough field, then they are thinking about habited islands, of course enhancing their chances of being rescued, and then I wonder whether they knew about the SS Norwich running aground. If they had any idea this island was the site of an earlier search and rescue, that may have been why they decided to put down there. On the other hand, has anyone actually flown over that area, I might just try it someday. Say you are up there, you cannot see Howland, what can you see? Certainly you see some land, and where there is land, there is a chance to land on it. I could never believe FN and AE would have chosen, I mean chosen, to say well, "lets keep looking for Howland until we run out of gas, then parachute into the deep blue shark infested sea". No I think the parachutes were there for emergency evacuation in the case of total engine failure, and a plane plummeting out of control. The facts do not seem to bear this event out. AE would have landed the plane not jumped out of it. Dana L. Sibilsky MD ************************************************************************** From Ric To see more than one island at a time over that part of the Pacific you'd need to be at - oh - 30,000 feet or so at least. You'd also need a sky free of the scattered cumulus deck that forms at about 2,000 feet nearly every day. From 1,000 feet, where Earhart said she was, land is an extremely scarce commodity. As for flying over that area, if you'd like to give it a try you'll need an airplane with about 2,000 miles of range to do it safely.

Was there any evidence that they were on a LOP, in addition to that garbled message which could have many different meanings? If they were following the LOP, was his navigtion so bad that he missed his destination by 100 miles? If he was closer to Howland (which the "must be on you" received as a strong signal implies), why did they miss both Howland and Baker? LTM Harry #2300 *************************************************************************** From Ric Once more - with feeling.... There was nothing garbled about Earhart's statement "We are on the line 157 337" The questionable part is her subsequent comment about "running on north and south line" or "running on line north and south" and the only thing that makes it questionable is the way the entry was crammed into the available space by the radio operator who was typing the log and the clear indications that he was caught off-guard by this last part of the message. Nobody in 1937 who understood celestial navigation techniques had any doubt that the "line" Earhart referred to was a Line of Position that fell through her intended destination. The same is true today. There is no other rational explanation. Let me try to explain. On that day, in that place, the sun rose at 67 degrees. (You're flying along and you look out at the predawn horizon. Look at your compass, correct for variation, and find 67 degrees True. That's where the sun is going to come up.) Because the Earth is round, exactly where you are on this ball determines exactly WHEN you see the sun rise. Obviously, anyone to the left or right of you is going to see the sunrise at the same time you do, but somebody in front of you will see it sooner and somebody behind you will see it later. In other words, the precise moment you see the sunrise tells you (and your buddies along a line to your left and right) very accurately where you are in an east/west sense, but you don't have much information about your north/south position. That line you and your left/right buddies are on is a Line of Position. Noonan knew ahead of time that the sun would rise at 67 degrees. A Line of Position is always 90 degrees to the observed body (in this case, the sun), so he knew in advance that the rising sun would give him a Line of Postion that ran 337 degrees one way and 157 degrees the other way. All he had to do was note what TIME the sun rose for him and he'd be able to draw a 337/157 line on his map and say, "Okay, we're somewhere on this line." That line is going to fall somewhere (200 miles more or less) west of Howland. Now he draws a parallel 337/157 line through Howland and measures the distance between the two lines (let's call it 200 nautical miles). He now determines how fast the aircraft is travelling (let's say 115 knots). He now knows that in an hour and fortyfive minutes he'll be somewhere on that 337/157 line that passes through Howland. If he doesn't see Howland right out there in front of him, he at least knows that it's somewhere on the line to his left (337 degrees) or right (157 degrees). Fortunately, there are other islands on or near the same line (Baker, McKean, and Gardner), all of which are on the 157 degree side of Howland. That means that he can't afford to look in the 337 degree direction very long because if he is already north of Howland there is nothing out there but the deep blue sea. Running down the line in the 157 degree direction, on the other hand, virtually guarantees that he'll find land of some kind before he runs out of fuel. Think of the Line of Position as an interstate highway (spelled "dual carriageway" in Britain) with four exits but no signs. Noonan doesn't know where he is on the highway but he does know that as long he heads southeast while he still has at least three hours of fuel left he is bound to come to an exit. Turning back to the Gilberts would be abandoning the only sure bet he has. Could Noonan have hit the LOP as much as 100 miles from Howland? Sure. Would that be terrible navigation? No. That's an error of less than 5 percent in a 2200 nautical mile flight with virtually no landmarks. Radio Direction Finding to "fine tune" the navigation for the last 200 miles or so was essential, but that part of the plan failed. The strength of the transmissions heard by the Itasca does indicate that the aircraft was "close" to Howland, but how close is "close" is purely a judgement call. That's about as simple as I can make it. I hope it helps.

(my guess is 3/16" to 5/16" by 1" to 1 1/8") Does this appear to be where a manufactures tag of some sort may have been affixed? Any evidence of small brads or rivets? A very intriguing piece of somebody's history How large is the original negative of the May 20 picture? When I look at the refection in the side of the aircraft, I can make out the light colored suitcase, and the tops of the two taller thermos bottles. Adjacent to the larger refection of the thermos bottle, there is a shape or lighter area inconsistent with the detail visible with regard to the suitcase. Could this be a refection of a similar handle to 2-4-v-100? Or are the geometry's wrong to see the top of the object in this photo? At the degree of resolution I am able to construct with regard to the May 20th picture, I cannot tell for certain, but I believe the angle is wrong to be able to see any appreciable detail in the reflections in the cap of the larger thermos bottle.

Zorn 1562C *************************************************************************** From Ric For those who missed it when it was posted November 30th, here is a professional assessment of the photos in question: ************************************** FINAL LETTER OF OPINION Dear Mr. Gillespie, Thank you for sending the negatives of TIGHAR artifact 2-4-V-100 and of A. Earhart and F. Noonan loading NR16020 depicted in the photograph taken by Dustin Carter at Burbank Airport on May 20, 1937 (may20dep.jpg). This letter addresses the relationship between 2-4-V-100 and the rightmost canister-like object located in a group of four canister-like objects located on the ground to the right of A. Earhart's feet. While the JPEG image may20dep.jpg shows this canister-like object to be overexposed, the original negative is properly exposed. Several structures present in 2-4-V-100 are absent in the canister-like object in may20dep.jpg. These are: 1) 6 metal bands that wrap around 2-4-V-100, and 2) what appears to be a handle located at the top of 2-4-V-100. Further, 2-4-V-100 has a transition area from its neck to its body that is flatter (has a smaller angle relative to vertical) than that shown in the canister-like object of may20dep.jpg. This difference cannot be due to damage to 2-4-V-100 because the required deformation would not result in the smooth surface seen in this part of 2-4-V-100. While there are additional differences between 2-4-V-100 and the canister-like object of may20dep.jpg, these reasons are sufficient to establish that these are different objects. Therefore 2-4-V-100 does not match the canister-like object seen in may20dep.jpg.

Those are impressions stamped into the metal. The body of the cannister is a single sheet of metal. I can see one "ring" around the object in the May 20 photo but it does seem to be a slightly different distance from the top of the cannister than is a similar "ring" on the artifact. The handle on the artifact rotates freely and we had speculated that a similar handle on the cannister in the May 20 photo might be oriented edgewise to the camera. The differences in the transition area from the neck to the body do, however, seem to be a disqualifier. Ric ************************************************************************** To which Jeff replied: Ric, Here are clarifications to your questions: By "metal bands" I also mean "impressions stamped into the metal". I did not mean to imply that sole source of the metal bands could be seperate pieces of metal applied to the body of the canister, but rather they are visual features present on the canister. may20dep.jpg has a circular top, possibly a cap, composed of a polished metal containing a complex reflection. It is the reflection of adjacent items in the circular cap which gives the mistaken impression of a handle.

If he only got one he would have trouble with ground speed and that could put his LOP projected through Howland off but he would still have a good idea of over all ground speed from Nauru to the LOP so he was not totally without input.

Ric, I will give it a try. Draw a line (Line Of Position) from Cincinnati to Vicksburg. You can verify when you reach that line, but you don't know WHERE along the line you are for absolutely sure. You could be north of Cincinnati or south of Cincinnati. You DO KNOW you are on that line or within plus or minus 5 miles of the line. At 1000 feet under an overcast, it is difficult to see far. Cincinnati airport is only two football fields long and one football field wide with NO bleachers. Good luck in finding it! So you know that there are five or six other, even larger airports along that line and if you don't find Cincinnati, you have a very good shot at finding the others or reaching Vicksburg itself. Vicksburg, by the way is about 10 times the size of Cincinnati and it's painted bright red! Now change the names to Howland (Cincinnati) and Gardner (Vicksburg) and see if it doesn't make some sort of sense, especially given that they are the only landfalls within your current fuel range and the only other option is to "ditch" in the middle of Lake Michigan (re: Pacific Ocean).

I'd like to see that statement backed up by some verification. Until then, the statement is so categorical that it undermines the credibility of the accompanying statements, which I'll briefly respond to anyway. > To have Noonan be on that line he would have to be pretty damn far off course > north or south but not east or west. Ric is correct, Don, when he says you don't understand what a line of position is. The whole point of the LOP is that Noonan's accuracy north or south is irrelevant-- spot-on, or hundreds of miles off course, he would still hit the calculated LOP without fail. > If he were north of Howland, they would have seen it when the turned > south. If they were south of Howland, they would have seen Baker when > they turned north. This idea is incomplete. There is no assurance that they would have seen either island under any circumstance other than an almost precise flyover below cloud cover. It is more likely that, whatever their final fate, Earhart and Noonan were within nominal visual range of Howland (and later, presumably Baker), and failed to see either of them because of scattered cloud cover and cloud shadows. It helps to have the experience of actually having flown over the trackless and immense Pacific to fully appreciate how difficult it is to pick out a small island from hundreds of dappled cloud shadows. Without a good DF bearing, spotting your target from more than a few miles at any altitude can quickly become a lottery. > But what if they did hit the line a hundred miles south, do you > think they would say to themselves, > "Well. . . Howland is not here. I don't think we know where we are, > so let go south for three hours and see what's down there" Whether or not they actually made an attempt to follow the LOP to Gardner, Noonan had no reason to ask what was on the southern extremity of the line: As one of the foremost experts of Pacific aerial navigation of his time, he certainly knew the answer: The Phoenix group, including Gardner. There is no evidence that he hit the LOP several hundred miles to the south (on the contrary, the evidence indicates that he guided Earhart to a point on the LOP rather close to Howland), and as has been explained countless times here in the past, he didn't need to be several hundred miles south of Howland in order to hit the LOP. However, in the very unlikely event that they were off course by several hundred miles to the south, it would have placed them that much closer to the Phoenix group and made a course of 157 even more compelling. > In my opinion, they simply could not have been on the Howland LOP > and not found Baker at least.. With maybe four hours fuel left, they > could have almost gone to Niku and back. This is false, for two reasons. First, as I mentioned above, visual conditions could have precluded them from seeing Baker unless they were virtually on top of it. Second, it is possible that they reached the LOP south of Howland or Baker, and despite an attempt to run the line north for several miles, saw nothing. Knowing that with 4 hours of fuel remaining they were virtually assured of reaching the Phoenix group by following their known LOP (and, if they were unknowingly north of Howland, reaching Howland or Baker long before that), there remains a very strong possibility, even probability, that they ultimately chose to fly a course of 157 degrees. Combined with the strong physical and anecdotal evidence that has built up over the years, it is, in the absence of hard physical evidence otherwise, impossible to reasonably deny the possibility (note "possibility") that they reached Gardner and landed there, dying of injuries and/or exposure in the weeks that followed.

My guess would be that the airplane would have to buzz the ship to be heard by anyone on deck. Can you see an Electra that's 10 miles away at 1,000 feet? Dream on. Could the people on Howland or Baker have heard a Lockheed Electra that was 10 miles downwind at 1,000 feet? Ever been on an atoll? Any idea how much ambient noise is created by the surf on the surrounding reef? We didn't hear the "phantom" airplane on Niku until it was very close. Those of us onshore didn't see it because we were back in the bush and couldn't see the sky. I don't know why the people aboard Nai'a didn't see it. But you're right about one thing.

He needs both sun lines. That means that unless the sky was clear enough of clouds (a possibility) between abouut 5.15am to 5.54am local to let him take 3 star shots, (and that assumes he is lucky enough to catch stars exactly on the meridian at twighlight), he can't get a reasonable fix until around 10.30am local. Also, any navigation relies on knowing how long, how fast, and in what direction they were travelling. Noonan had around 9 hours when he: 1 Would find it difficult to get a celestial fix. (No horizon - and yes, an inverting eyepiece may help, but trying to keep the aeroplane dead level at night is not like having a horizon to reference so any readings would be inaccurate). 2 Had to rely on Amelia flying at a perfectly constant ground speed (he couldn't use the drift meter at night to get drift and ground speed so that's not likely) 3 Had to hope the wind remained constant (also unlikely over that distance) 4 Had to know the wind speed and direction to start with (the last reading would be with the drift meter before dark on 1st July - and then only if they were low enough) He could not know with only one sun shot, just where along the its LOP he was. In fact he could not even know his longitude i.e. the distance he had travelled from Lae. He should be somewhere in the vicinity, but even if Howland was "just over the horizon", he was stuffed without the Radio Direction Finder until he could get two sun shots. And he could not get a simple lattitude shot until noon, when the sun was at its highest overhead. >Obviously, anyone to the left > or right of you is going to see the sunrise at the same time you do, but > somebody in front of you will see it sooner and somebody behind you will see > it later. In other words, the precise moment you see the sunrise tell you > (and your buddies along a line to your left and right) very accurately where > you are in an east/west sense, Close, but it only works like that on the South of the equator. North of the Equator for your buddies to see the sunrise at the same time they would have to be on a line more like 023/203. When the sun rose on the 2nd of July: At 10 degrees North of the equator and 90 degrees angle to the equator it was about 5.55am. At 5 degrees North of the equator, sunrise was about 5.45am At the equator 0deg on the 2nd of July the sun rose about 5.35am. At 5 degrees South of the equator, sunrise was about 5.45am. At 10 degrees South of the equator it was about 5.55am. So the line of "beginning of daylight" is a vee with the point at the equator. Using the tables and the sun sight, that is part of how you determine your latitude, unless you wait for a noon sight when the sun is at its zenith (directly overhead). So Ric's LOP and time his buddies see the sunrise is correct if it does not cross the equator. The line that passes through Howland and Niku only just crosses the equator so the difference would be negligible. It would be interesting to see exactly what direction the sun comes from at Niku in July. I've just taken altitude and direction at about 20deg South and in December it is 98 degrees magnetic. That's 90 degrees true, or Due east. So next time you are on Niku in July how about a sunrise direction??? So whether 337/157 was a "Line Of Position" or "the Line they were flying along" which is probably more likely, owing to it passing through Howland and Niku is debatable. That they reported being on the line 337/157 is logged. Exactly what was said in the running north ??? south message has been questioned. If they said they were running north TO south, then it's a fair bet they were heading towards the Phoenix group. Running north AND south suggests darting back and forth along a heading and sounds really unlikely.

Fred's LOP was in effect a 'band' due to the inherent errors inherrent in most LOP's. In the instant case, the astronomical data was rounded, a second or two in noting the rise of first light, and again when the lower limb cleared the horizon, ditto the second line to determine ground speed since the first line, the assumption of what the ground speed would be to the advanced line thru HOW, and the fact that Fred's HOW was several miles west of its actual position, results in a line that has 'width'; a cumulative error easily between one and ten miles; for even the best of navigators. Since an error that positioned the line further east would put them even closer to Howland [acct. error of Howland's position], increasing the possibility of seeing Howland [initiallty or when flying the LOP] it is more reasonable to believe the line was a couple miles at least, short of Howland's '37 position. Thus increasing their actual distance from Howland initially, and while flying the LOP. It would thus be farther from Bak as well, and perhaps fortuitously right on Gardner. {the LOP thru Howland's position passes about 5 - 7 mi. [as I recall] east of Gardner. Conclusion: Flying the LOP along its westerly limit of accuracy would decrease the possibility of seeing Howland and Baker, but increase the possibility of seeing Gardner.

Niku Per Ric: "We just don't seem to able to get across why it is that following the LOP was greatly preferable to turning back to the Gilberts" Think you missed my point. I probably didn't make it very well. Assuming AE had absolutely no idea what she was going to do if she failed to find Howland, then certainly it made sense to follow the LOP. On the other hand, if she had a preconceived Plan B (and 3.5 hours of fuel remaining) then it would not have been out of character for her to follow that plan. That's why I consider the Vidal papers so important. Sure wish we had a Forum member in Laramie! (By the way, I agree that if they DID turn back to the Gilberts they didn't make it, but a documented backup plan could open up new areas of inquiry.) Alan's explanation of LOP navigation is the best yet, but the fact remains that FN's sunrise LOP still had to be advanced to Howland by dead reckoning. There is no evidence that Fred was able to take the additional sun and moon shots that would have allowed him to get a better fix on their position. If FN was able to get only a single sun shot (remember AE reported cloudy weather), the margin of error increases the farther the LOP is advanced eastward by DR. This would seem especially true if Fred was having trouble gauging headwinds or drift. (And if he wasn't having trouble with one or the other of these items, they should have found Howland.) So it is well within the realm of possibility that AE was considerably short of (or past) Howland when she turned onto the 157/337 line -- in which case said line would not run through Niku. If Alan's theory is correct, then two people who were desperately seeking land -- any land -- not only flat out failed to see Howland, but probably missed Baker as well. I suppose in sunrise conditions this, too, is possible. BTW, a contemporary news account, written during the search and datelined Honolulu, reported the total population of the Phoenix Group in July 1937 as three (count 'em) people. Another reason Earhart MAY have thought her chances were better in another direction, even if Niku was closer. LTM (who realizes all this stuff was hashed and rehashed some months ago) Pat Gaston ************************************************************************** From Ric The only comment Earhart made about weather was "partly cloudy" logged by the Itasca at 04:53 (and probably sent at AE's regular transmission time of 04:45). The other alleged reports of "overcast" conditions do not appear in the original log and seem to be the later invention of Warner Thompson, captain of the Itasca, as part of his campaign to exonerate himself from blame. Let's remember that the alleged comment about turning back to the Gilberts was made by Amelia Earhart, not Fred Noonan. Let's remember also that the happy coincidence of the sunrise LOP, advanced through Howland, falling through several other islands was entirely a function of when the flight took place. The world flight was far behind schedule and neither AE nor FN could have known, until the night before the flight, exactly what day they would be making the trip. As long as we're debating anecdotes, I'll mention that Martin Aircraft Company representative Francis "Fuzz" Furman, who in 1937 was based in Bandoeng , Java, spent quite a bit of time with Fred while the Electra was there having maintenance done. Fuzz (whom I interviewed in 1989) remembers that Fred was concerned about the Lae/Howland leg and was almost obsessive about repeatedly checking the accuracy of his chronometer. Conversely, Chater describes Earhart and Noonan as being very confident about the flight immediatley prior to departure. Of course, by that time, Fred knew that he'd be approaching Howland on the mornng of July 2nd and precomputing his sunrise LOP showed him that he'd have a line that would give him three other islands as alternates. Couldn't be better.

A self-promoting journalist named Sylvanus Cadwallader alleged that he saw Grant roaring drunk during a behind-the-lines boating foray up the Yazoo, but Charles Dana, Assistant Secretary of War, was on the same trip and reported nothing untoward. Dana had been dispatched by Stanton specifically to check on reports of Grant's intemperance.

Can you guarantee that Fred was able to get good celestial fixes during the night, and that he knew what the wind was during the last few hours of the run for the island.

Ships log;. . . Sky Conditions; Clear! Ric said that it would be difficult to see the island if they were at 1,000 feet and within 10 miles. OK. They were not in between Howland and Baker and if they ran 10 miles north without seeing either one, then they had to be south of Baker by more than 25 or so miles. That would put them over, or close to 100 miles off course to the south. To do that, they would have to know the ground speed from the last known position and not figure in any cross wind component. I doubt they had a perfect 90 degree cross wind which would change the track, but not ground speed! >Knowing that with 4 hours of fuel remaining they were virtually assured >of reaching the Phoenix group by following their known LOP . With four hours of fuel remaining, it doesn't seem logical that they would only search to the south. With that much fuel, they could have gone one hundred miles to the north, then one hundred miles back to the starting point and still had enough fuel to reach Gardner and circle for 45 minutes. (Based on what we think we know about fuel flow and airspeed of the Electra) Also, if they were on the Howland based LOP, the only island they would be assured to hit in the Phoenix Group would be Gardner. They'd miss all the rest! But there are two islands to the north. All things being equal, would you give up two for one? >Combined with the strong physical and anecdotal evidence that has built >up over the years, it is, in the absence of hard physical evidence >otherwise, impossible to reasonably deny the possibility (note >"possibility") that they reached Gardner and landed there, dying of >injuries and/or exposure in the weeks that followed.

There are entries for "Weather by Symbols" and for "Clouds" which are broken down as to "Form", "Moving From", and "Amount." There is a log entry for every hour of the day. The entries for 1 a.m, 2 a.m., and 3 a.m. under "Weather by Symbols" are "B" which is defined as "blue sky - cloudless." From 4 a.m. through noon the entries are all "BC" which is defined as "blue sky with detached clouds." The cloud descriptions for each hour are as follows: 4 a.m. alto cumulus moving from east, amount "2" 5 a.m. cumulus moving from east, amount "2" 6 a.m. strato- cumulus moving from east-northeast, amount "4" 7 a.m. cumulus moving from east, amount "3" 8 a.m. cumulus moving from east, amount "3" 9 a.m. cumulus moving from east, amount "2" 10 a.m. cumulus moving from east-southeast, amount "3" 11 a.m. Strato-cumulus moving from northeast, amount "5" 12 noon cumulus moving from northeast, amount "5" (Note: At 10:40 a. m. Itasca left Howland and headed northwest to search for Earhart because it looked like there were more clouds in that direction, so the cloud conditions at 11 and 12 do not necessarilly reflect what was happening at Howland.)

But I 'm not willing to bet the farm on it. Actually, the idea here, using your metaphorical device, is that Earhart and Noonan, if they did decide to fly a course of 157, did it because they knew that not the "farm", but their lives were "on the table", and that a heading of 157 was probably their "best bet" for keeping them.

That azimuth of the sun would be approximately the same for a fairly wide area, even a little south of the Equator. A sunrise Sun Line is very nearly a great circle, with the azimuth toward the Sun changing by a degree each 69 miles or so. Howland is very near the Equator; the Sun's LOP for the early daylight hours was about 157-337 for that vicinity, both north and south of the Equator. To see the sun rising perpendicular to where its LOP is 023/203 that day, the observer would have to be well north of the Sun's (North 23 degrees) track. ========================================================================= Date: Fri, 17 Dec 1999 19:07:29 EST From: Alan Caldwell Subject: Re: LOP's, Gilberts, Good Gracious,ETC.

When they get in closer they need to descend below the cloud bases in order be able to look for the island (hence Earhart's later comment that she is at 1,000 feet). Once they're down low and the sun is up, they'll have to make do without further sun shots. The question is, how far out did they descend? If I was Noonan and I was still about 200 miles out when the sun came up, I'd want to stay high long enough to shoot some "speed lines" to confirm my groundspeed.

"So the line of "beginning of daylight" is a vee with the point at the equator." This is utter hogwash. The LOP obtained locally is good for about 100 miles in either direction, and is, in reality, a tangent line to a great circle around the earth. Look at any picture of earth from space, and you will see the terminus, or the edge of light and shadow. It is a smoothly varying position (and angle) relative to its position. The LOP angle changes slowly with latitude, but does not become a "V" anywhere, nor does it change angles to 23/203 degrees until nearly a change of 90 degrees latitude. As stated, the LOP is locally valid, and all aerial navigatiors, including FJN, knew their best fixes were good to about 10 nautical miles, which is good enough (usually) to get you close to visual range. FJN knew that the LOP was valid wherever he observed it, and that it was valid for approximatley 100 miles to either side of him. The errors associated with an inaccurate latitude within 100 miles or so is well within the 10 nm error limit. There are really two critical questions that can't be answered. (1) Did FJN really observe the sun at daybreak, or did he pre-calculate the LOP without an actual observation that would fix his longitude? (2) Did he take another sun shot later on to determine if his dead reckoning navigation of the previous LOP to Howland was still accurate?

So maybe year round average of over 80deg was not totally accurate, however since I know you prefer the "scientific method" to a good guess I'll amend my statement to read: "year round average of 81.66deg F". Now to the support for my hypothesis: Item 1.. PACIFIC ISLANDS REPORT Pacific Islands Development Program/Center for Pacific Islands Studies EL NIÑO INCREASES WATER TEMPERATURE IN THE PACIFIC. TOKYO, Japan (April 10, 1998 - Radio Australia)---The Japan Meteorological Agency says temperatures in parts of the Pacific Ocean have reached record levels. The average water temperature in the eastern equatorial region rose to 29 C (84 F) in March... However you'd be surprised how little the (measured - not guessed) water temperature varies through the year in the tropics. Item 2.. In the exact region where TIGHAR is searching (170E to 170W & 5N to 5S) (Howland is 176.38W & 0.48N and 180 is actually right in the middle between 170E & 170W) the WATER temperatures for 1994 (the last for which I have complete records) was: Jan 82deg Feb 82deg Mar 81deg Apr 82deg May 83deg Jun 82deg Jul 80deg (whoa - getting down near my average) Aug 83deg Sept 81deg Oct 82deg Nov 81deg Dec 81deg These figures are courtesy of (wait for it)... The Ocean Climate Laboratory (OCL) at the National Oceanographic Data Center (NODC) And I'd expect their guess to be at least as good as mine :-) Item 3.. As of 3 Hours ago (1800UTC), the temps at Tarawa/Kiribati according to our VERY PRECISE measuring equipment located AT Tarawa was: Water: 81degF Air: 79degF The outside air temperature where I live in Australia at 6.00am local was 81degF. I haven't collected a local sea temp this morning, but based on yesterday's figures it should be around 82degF at this time at the surface in deepish (over 30 feet) coastal waters. I only get Kiribati sea temperatures when i want them, but I can average them out over a year to see how far out my guess was :-) I also have hourly reports of wind speed/direction and gusting at Kitibati and a few other things less likely to interest people. (From an Australian University measuring station). However as I suggested, and Tom I think also suggested - even in warm water you will eventually suffer from hypothermia - (just ask the survivors from the Titanic).

Lambrecht's report on the website. One of the things that occurred to me was the fact that Lambrecht & his flight seemed to experience no difficulty in locating or identifying any of the islands in the Phoenix chain (except for Winslow Reef, which was probably awash when they searched for it) or in navigating their way back to their ship, which was apparently underway during the search. Now I realize that although they were out of visual contact with the ship for most of the search, Lt. Lambrecht did specifically comment upon the excellent radio communications they experienced (something AE/FN obviously did _not_ have as they approached Howland) & that they were probably never more than 100 miles away from the ship at any given time; Never-the-less, they did navigate a somewhat circuitous route, changing course & direction on numerous occasions in order to reach each of the islands in the chain. However they were able to make such landfalls in very close proximity to the headings recorded on their charts, having no more available navigational equipment (maybe less) than AE/FN had aboard the Electra. Lambrecht also reported no difficulty in seeing any of the islands upon their approach, other than occasional rain squalls that were apparently quite common to that area & usually these were very local occurrences. He also reported being able to see the ship some 30 miles away. (Maybe she was smoking?) While there is always the possibility that Lambrecht & his flight experienced more pristine weather conditions than AE/FN, a week after their flght terminated, it would seem that if AE/FN, did elect to fly southeast on their LOP & if their fuel consumption estimates were reasonably accurate, they should have been able to spot these islands at the same locations on their charts as the Navy flyers did, the only _IF_ being whether they did have sufficient fuel reserves to actually _reach_ one of the islands & then pick out a reasonably safe appearing stretch of reef flat to negotiate a wheels-down landing.

RD (the dead horse lives?) ========================================================================= Date: Sat, 18 Dec 1999 09:17:16 EST From: Ross Devitt Subject: sextant/octant I've been ferreting around for information again. Octant vs Sextant - How did Noonan navigate at night? At its simplest... (and most of this is pulled out the encyclopaedia). A sextant uses the horizon as a reference point. When you look through the telescope part at the sun, you move a lever, which moves a mirror, and adjusts the reflected image of the sun downwards until the bottom of the sun just touches the image of the horizon. If you look through an inverting eyepiece, when you move the mirror, instead of the image of the sun looking like it comes down to meet the horizon, the image of the horizon looks like it is moving up to meet the sun. In practice the inverting eyepiece would be more likely to be used when trying to sight a faint object like a star. To use a sextant, you MUST be able to see the horizon. At night away from civilization, the horizon is very unlikely to be seen distinctly. A "bubble octant" on the other hand does solve one problem - partially. In aerial navigation a bubble octant, sometimes called a bubble sextant is used, in which a spirit level is reflected into the field of view in such a way that the center of the bubble indicates the true horizon. It still requires clear enough skies to take sights on at least 2 and preferably 3 stars with as wide an angle as possible between them. At night navigation with no visible horizon can never be as accurate as a daytime sun sight or a twilight star shot because the navigator has to take his height above the earth into consideration. Even taking sights using a sextant from the deck of a small yacht, you have to correct for the height of your eye above the surface of the sea. Imagine trying to obtain that sort of precision in an aeroplane (ever flown in absolutely no turbulance?). So what does the sextant / octant do? Basically it measures angles very accurately. At any given moment in daylight, the sun can only be over ONE spot on the earth's surface. When you shoot the sun with the sextant you get an angle between the horizon and the sun. Picture the sun sitting on the top of a "cone". The angle is the steepness of the sides of the cone. Using this, and the direction to the North or South pole and a few other things you can calculate where on earth you are at the moment. This might make this whole thing simpler for people who don't want to learn about azimuth, zenith, intercepts, declination and so on.... For a nice one page explanation of how all this works, look at: http://www.nav.org/cel/introduction.html RD ========================================================================= Date: Sat, 18 Dec 1999 09:43:26 EST From: Alan Caldwell Subject: Re: LOP << The Moon had risen very high around the time of sunrise, and sighting it might have been impossible without an overhead window, but if it was visible it would have been useful later in the morning for a cross-LOP. >> Good comments, Beth. I'm having a little trouble understanding the point of our LOP discussion unless some would have a master navigator not having much of a clue as to what he is doing. Unless I am misinterpreting some of the postings it would seem there is a determination to "prove" Noonan headed out into oblivian not knowing where he was or where he was going so we all ought to just pack it in. Or am I being too harsh? There have been good LOP explanations on the forum in addition to my posting which apparently was not as simplified and clear as I had hoped. I'm not certain everyone understands LOP yet. To post celestial procedures doesn't get us any where and that's why I tried to boil it down to only make a couple of points -- how to get a ground speed and how to know when one is on an LOP going through destination. I'm missing the point on the rest of the arguments. No one has claimed that they know Noonan did or did not take star or sun shots. We can not know what altitude he was at or what altitude the clouds were or their extent. We only have the Itaska log giving an indication of cloud cover and those entries looked to me as though sun shots were possible. If the sun was visible I would almost believe the moon was also. That morning the moon's azimuth allowed for a good cut on Noonan's sun shot -- at least 30 degrees and the highest altitude was 76.7 degrees. One posting by Ross said, "Don't forget that to determine the sun line Noonan has to not only see where the sun comes up, but also to take a sight for the angle of the sun over the horizon - something he cannot do until at least 7.30am on the 2nd of July, followed by another one about 3 hours later (to give the sun time to move -well the earth to move- far enough for an accurate second sight." Not exactly, Ross. First of all I don't know how to take a sun shot when the sun is over the horizon. The sun as it peaks over the horizon is basically good only for an azimuth to reset DGs. Until the sun is about ten degrees altitude the LOP would not be very accurate which would not stop a navigator from shooting for LOPs, however. They'll refine as the sun gets higher. Also it doesn't take 3 hours to get a second shot. The sun rises fairly rapidly and ten minutes is sufficient. Below, courtesy of the Naval observatory is the selected sun table for Howland on the morning of July 2, 1937. Time Altitude Azimuth 06:20 0.7 67.0 06:30 2.8 67.0 06:40 5.0 66.9 06:50 7.2 66.9 07:00 9.5 66.8 07:10 11.8 66.6 07:20 14.1 66.4 07:30 16.4 66.2 07:40 18.6 65.9 07:50 20.9 65.6 08:00 23.2 65.2 08:10 25.4 64.7 08:20 27.7 64.2 08:30 29.9 63.7 08:40 32.2 63.0 You will note the sun peeped at about 6:20a local with an azimuth of 67 degrees. That was not good for very long. You will also note the altitude changed about two degrees every ten minutes. That's a sufficient change to use as a plot. By 8:40a local the azimuth had changed 4 degrees. Granted that makes a skinny convergence but better than none. While I'm at it here is the moon table for the same period. Time Altitude Azimuth Fraction illuminated 06:20 72.5 40.7 0.37 06:30 74.0 34.1 0.37 06:40 75.2 26.4 0.37 06:50 76.1 17.5 0.36 07:00 76.6 7.6 0.36 07:10 76.7 357.3 0.36 07:20 76.3 347.2 0.36 07:30 75.6 338.0 0.36 07:40 74.4 329.8 0.36 07:50 73.1 322.9 0.36 08:00 71.5 317.1 0.36 08:10 69.7 312.3 0.36 08:20 67.8 308.3 0.36 08:30 65.8 305.0 0.36 08:40 63.8 302.2 0.36 Ross, I'm not clear why you think Noonan needed a three star fix between 5:15 and 5:54a. The significance of those times escapes me but it is late and I'm tired - Christmas shopping. I also don't understand why you think he couldn't get a reasonable fix until 10:30a. By 7:00a he ought to have obtained a Hell of a fix with the sun at almost ten degrees altitude and the moon, albeit high in the sky, at about a 60 degree cut. Where am I wrong? Someone will say Noonan could not see the moon at that altitude because of the cockpit configuration but they will be incorrect. I guarantee I could see the moon from the cockpit and if you'll think about it you'll figure out how to do it. I think Ric answered the no horizon comment and how to keep the airplane level so I won't. We apparently don't know if Noonan had drift flares aboard so we can't say he couldn't use the drift meter at night but if he could get any star fixes in those 9 hours he was OK. The wind didn't need to stay constant. I know of no place where it does. Noonan would have been the last person to expect it to do so. Also he didn't need to know the the start wind speed and direction. That was easily computed as he was in sight of land periodically for a long way out. We know he went past Nauru so he was doing OK at that point and his problem now was from Nauru in to Howland. It is possible he could get a position over flying the Gilberts. I sure would have tried if I had visibility and there were ANY lights. Ross, you are correct that one sun line would not tell Noonan where he was on the LOP nor would it give him his exact longitude. He still needed to cross the LOP with another to know that but I have a feeling he didn't wait till noon to get another sun shot for latitude. Alan ************************************************************************ From Ric A couple of quick comments - one investigative and one administrative. Because the 67 degree postion of the sun, from which a 337/157 LOP is derived, was only valid at sunrise and for 10 minutes thereafter, we are pretty much forced to assume that IF the 157 337 "line" that AE referred to is an LOP, he had to get it in those first ten minutes. We must also assume that it is that LOP and not a later one that he advanced through Howland, otherwise AE would have said, "We are on the line 155 335" or some such. Why would Noonan cling to an early, and perhaps less accurate, LOP unless there was something about it that he really liked? Such as the fact that it offered alternate destinations? And now for something completely different. When someone submits a posting but doesn't sign their name I generally just use an abbreviated version of their screen name. I can see, however, that this practice can create some confusion as when Alan refers to Mark P. (abbreviated screen name "bethpage89") as "Beth." From now on I'll give everyone at least a first name and last initial if you don't sign the message yourself.

Any airplane 5 miles away at 1000 feet altitude would be almost impossible to see or hear based on my own personal experience.

I could see the charter going L.A., Honolulu, Fiji, then flying the reenactment as a separate mission out of, and back into, Fiji. Then home. Or maybe it would be cheaper to charter only the reenactment portion of the flight and have people travel scheduled service to and from Fiji (it's only about $1,000 round trip from L.A.). That way we we could charter an airplane out of New Zealand or Australia and have them meet us in Fiji. Or if we were going to charter an Aussie airplane anyway, maybe it would be more "marketable" to recreate the whole flight and have everyone meet in Sydney for a flight to Lae, and then do Lae/Howland/Niku and then maybe down to Pago Pago to refuel before heading back to Sydney. We'd time it so that we'd do the reenactment on July 2.

When I was around 9 years old and first read that line, "We must be on you but can not see you", it seemed to me that they were convinced they were very close to the island, and probably were. I still believe it to be very probable. And it seems to me that if they had the skill to get to the vicinity of Howland, especially without a working DF, and didn't see it because of cloud shadows, which to me is most likely, then they probably had the ability to fly a calculated (and advanced) LOP on a heading of 157 and reach Gardner. william 2243 ========================================================================= Date: Sat, 18 Dec 1999 12:52:01 EST From: Alan Caldwell Subject: Re: Reenactment << This silliness has gotten me thinking (always dangerous).

Sorry about the Beth comment. Ric, you will notice in the sun chart that although 67 degrees held only for the first ten minutes an azimuth minutely close to that held for much longer - say until 7:00a or possibly even 7:10a where the azimuth was within 4/10 of 67. Also that 67 degree azimuth was for someone exactly over Howland and we don't know that is where and when Fred took his sun shot. A 67 degree azimuth could also be obtained in other areas near Howland but at different times of course. The block of time we are working with is from 6:20a when the sun rose to 8:44a when Amelia announced the 157-337 report.

First question: are we sure we've got that right? Remember the Itasca was using that screwy 11.5 hour time zone. 06:20 Itasca Time would be 17:50 Greenwich. Zat what the tables say? Assuming 06:20 is the correct sunrise time for on-the-ground at Howland, is that the time that the first "limb" (I think it's called) peeks over the horizon or when the whole ball clears the horizon? How would being at 10,000 feet directly over Howland effect the time you saw the sun rise? Would you see it a few seconds or a few minutes earlier than the folks on the ground? Now go 200 hundred miles to the west. When you gonna see the sun? At 06:15 AE told Itasca that she was approximatley 200 miles out. That was her regularly scheduled transmission time so the estimate may or may not have been current, but assumming that it is, Is there anyway that they could have seen the sun at, say, 06:10 (17:40 Zulu) from 200 miles west of Howland at 10,000 feet?

The three areas I wanted to check using an accurate mask of the part are below and above the aft fuselage, and the top of the outboard wing skin. The first area is a spot near centerline on the lower aft fuselage about one to two feet aft of the tail wheel well. The second area is on top of the aft fuselage, one to one and a half feet off centerline between the upper gun turret and the fin. Finally, the outboard panel upper wing skin which starts about 14 inches out from the butt joint. The specific area I think might match is the forward inboard corner. There are several other areas of wing skin on the McChord B-18A that have similar rivet spacing and taper. The areas all had crossing lines which ruled them out. An earlier B-18 or DC-2 might not. I'd like to suggest that any forum member near the Air Force Museum at Wright Paterson look over the C-32 (DC-2) in the annex for other possible matches. My reason for thinking this might be a chunk of a Douglas rather than Lockheed airplane is based on the spacing of the rivets in their rows, and the spacing and taper between rows which agrees with several late '30s and early '40s Douglas aircraft, but does not apparently match the Lockheed 10.

Robert Klaus ************************************************************************* From Ric The lack of a crossing line of rivets on 2-2-V-1 is one of the features that makes it so unique. There are no finished edges present on the artifact, so it's a hunk broken or blown (but not cut) out of the middle of a larger sheet. That means you need a "throw" of at least 25 inches with no crossing line of rivets. On a fuselage, crossing lines of rivets are usually dictated by the presence of bulkheads or "circumfurentials." There are a few places on a Lockheed 10 fuselage that qualify, but I think you'll find that such unbraced spans are hard to find on most aircraft of that era (including the B-18 and the DC-2). Another hard to match feature of 2-2-V-1 is the combination of itty-bitty #3 rivets (shaft diameter of 3/32s of an inch) with 1 inch pitch (distance between rivets) in a .032 thickness skin. I've only been able to find that particular formula on the Lockheed 10. You usually find #3 rivets in thinner skins and spaced farther apart. I think you'll find that the similarly spaced lines of rivets in the DC-2/DC-3/C-47/B-18 wing are bigger rivets. The artifact has a very specific and complex rivet pattern. We've never been able to match it on any airplane, but we've come closest on the Model 10 Lockheed. Remember - "Almost don't count 'cept in horsehoes and hand grenades."

He didn't have to measure any angles hence didn't need to use his sextant (nor octant). All he required was a chronometer that was correct and an eye-ball view of the edge (limb) of the sun first peeking above the horizon. Sunrise was almost dead ahead. (He would need to make some minor adjustments for their altitude and for atmospheric refraction but he knew all about that stuff.) Once he had that time observation, his tables told him where he was in an essentially east-west sense. (Somewhere on a not quite north-south line) The tables also told him the exact direction of that line on that date -- The 157 - 337 line Amelia mentioned. That is the Sunrise LOP for July 2, 1937 and clearly the only way she would have known how to specify the line. They were somewhere on a line directed southward at 157 degrees and northward at 337 degrees. (Note that those are 180 degrees apart. It's simply a straight line running approximately north and south. It's slanted 23 degrees off from north-south. Just about the tilt of the earth's axis of rotation. Isn't that odd? ) ========================================================================= Date: Sat, 18 Dec 1999 18:19:47 EST From: David Subject: climb or stay low? I assume that AE dropped to 1,000 feet to find Howland which she couldn't locate at a higher altitude. Since she had several hours of fuel remaining and not finding the island, would she then began to increase altitude to continue looking or stay close to the deck? Wouldn't she have been better off to stay at a somewhat higher altitude, or did she descend because she was fairly confident that the island was near? LTM (whose # is in the mail - hopefully you received my check!) David ************************************************************************* From David Indeed we did. Thank you. Your membership materials will go out Tuesday. Eahart was at 1,000 feet almost certainly in order to get below the scattered cloud deck. Whether she later climbed back up to a more efficient altitude is a matter of conjecture but there are two compelling reasons not to do that: 1. It burns precious fuel. 2. You can't see any island that might appear. I would have stayed low.

Don J. *************************************************************************** From Ric Lockheed 10E Special c/n 1055 was delivered on July 24, 1936 with P&W R1340 S3H1 engines numbers 6149 and 6150. The Bureau of Air Commerce Aircraft Inspection Report which was signed upon the completion of repairs on May 19, 1937 shows those same engines still in place. Similarly, the aircraft was delivered with Hamilton Standard 12D-40 propeller hubs numbers 26333 and 26334. The same hub serial numbers appear on the May 19, 1937 report. The only documented change is to the propeller blades. The aircraft was delivered with Hamilton Standard 6095A-6 blade sets numbers 58831-32 and 58833-34. The May 19th report shows blades sets 66570-71 and 66572-73 installed. I agree that, from the look of the props after the accident, I would have suspected crankshaft damage. The prop tips on both engines were bent forward - a dead give away that both throttles were still advanced when the props hit the ground. However, the paperwork is quite clear that they just put on new prop blades. Must be tough engines.

Alan ========================================================================= Date: Sun, 19 Dec 1999 09:55:31 EST From: Alan Caldwell Subject: Re: sunrise Ric, I WAS using the screwy Itasca 11.5 hours off Z and that's what the tables are based on. Your altitude question certainly makes good common sense that the higher one is the earlier one would see the sun and that is true but the effect is fairly negligable. I found this comment in celestial navigation information. Altitude (negligible to 2 degrees) This factor is normally negligible. According to the IGRF, a 20,000 meter climb even at a magnetically precarious location as Resolute, 500 kilometers from the north magnetic pole, would result in a two-degree reduction in declination. While altitude may not have a significant effect the observer's east/west postition clearly does. If Noonan is several hundred miles West of Howland he will see the sun at a later time than an observer AT Howland. In checking the tables I found that at 180 miles west of Howland Fred would see the sun ten minutes AFTER an observer at Howland. If the sun rose at 6:20a at Howland Fred would not see it until 6:30a if he was 180 miles west of Howland. As to the screwy time between the Itaska and Howland I elected to use Itaska time of 11.5 off Z solely for illustrative purposes and have given no thought yet to resolving the difference to determine what someone at Howland would actually see. When I have some more data of possible positions for shooting 67 degree azimuths I'll worry about real time. I have given a lot of thought to the "200 mile out" call also and I think you are dead on that it had to be based on pre dawn celestial or maybe just DR. There is no possibility Noonan could have taken a sun shot at 6:15. Alan #2329 ========================================================================= Date: Sun, 19 Dec 1999 10:03:26 EST From: Roger Kelley Subject: Info on Amelia Last month the question of where Amelia had her L-10-E repaired following the Luke Field crash provoked me to do a little research. As a result, I discovered information which might provide answers. I discovered newspaper articles in the Glendale News Press which were published in March and April, 1937, which quoted Amelia as stating that her L-10-E was being repaired at the Lockheed Burbank facilities. One article in the Glendale News Press, dated April 1, 1937 related to Amelia and her mother, Mrs. A. O. Earhart, while they were shopping in downtown Glendale. This article mentions Amelia's residence and the repair of the L-10-E. It states, "At her Valley Spring Lane home in North Hollywood this morning, Mrs. Putnam verified the report that she and her mother had been in Glendale to "do some shopping." Later in the article, "Her airplane, which crashed at Honolulu on her proposed world circling flight two weeks ago, is being repaired a the Lockheed Aircraft Corp. factory in Burbank." To date, I have found nothing which indicates that the L-10-E was repaired in shops located at the Grand Central Air Terminal, Glendale. The Glendale News Press article of April 1, 1937 also confirms previous information that Amelia was residing on Valley Spring Lane at the time of her second World Flight attempt. I discovered some other neat stuff about Amelia. Although most, if not all, is known to Amelia's followers. First, I discovered two pieces of upholstery, approximately 5" x 4" each, dark red or maroon in color with a hand written note stating, "Pieces of upholstery used in Amelia Eheart's plane. Gift of Mrs. Max Green, March, 1975." Nothing more than this brief statement. Note that Earhart was misspelled. Could it be that Max was employed by Lockheed and snatched some scraps after the seats were completed and installed (or re-installed)? I'm searching for Max or his survivors at the present time. No luck so far. Second, I discovered the obituary of Neta Snook Southern, dated March 26, 1991 and published in the Los Angeles Times. She died at the age of 95 and was a flight instructor in her youth. Southern claims to have taught Amelia how to fly in 1921 at Kinner Field in what is now South Gate, CA. Third, I discovered another article in the Glendale News Press dated July 10, 1929, announcing the arrival at Grand Central Air Terminal of the first Transcontinental Air Transport planes to complete the New York to Los Angeles air/rail commercial trip. By rail and air, the trip took two days. The lead aircraft was piloted by Co. Charles A. Lindbergh and one of his passengers was Amelia Earhart. Amelia was listed as the "Assistant Traffic Manager of T.A.T." Help me out here folks. Was Transcontinental Air Transport the forerunner of Trans World Airlines? Does anyone know what became of T.A.T.? And last, I discovered several photographs of Amelia. One such photo was a non-professional snap shot depicting Amelia, a small girl, (approx age 5?), and a gentleman about 40 years old standing near each other ,in front of a wood frame house. Between the house and the three people is the upper and lower wing, and right landing gear, of an unknown type bi-plane. The caption reads, "Bert Kinner and daughter Dorothy with their favorite customer. Amelia Earhart's first airplane was Kinner-built in 1920. The Kinner residence, located on Flower Street, permitted easy access to the runway. (Cora B. Kinner)" Flower Street is located on the .west boundary of Grand Central Air Terminal, Glendale, CA Another photo appears to be a professional 8 x 10 depicting a young (25) Amelia standing next to the engine and prop of a bi-plane. The caption reads, "Amelia Earhart promoting Kinner aircraft and engines." One photo depicts Amelia in flight suit, wearing leather helmet and goggles, standing with her hand on the prop of a bi-plane which has "Kinner" painted on the tail. The caption reads, "Amelia Earhart beside her Airster, 1921." Although well composed, this photo appears to be a snap shot. Two other photos which appear to be professional 8 x 10, depict a bi-plane with a three cylinder engine and two bladed prop. One photo depicts the entire aircraft from the left side and the other depicts the entire aircraft from left front. The word "Kinner" is not painted on the tail. Nor can I detect any other writing on the aircraft. The hand written caption on one reads, "Built for Amelia Earhart in 1923 (but not delivered to her, due to health problems.) Had to quit flying because of sinus infection. However, she did fly it occasionally. See John Bark's book, shows A.E. with this job, tho incorrectly captioned as Canary." The statement "(but not delivered to her due to health problems.)" has a line drawn through it as if it might be a strike out. This same photo has a stamp on it stating, "JOHN W. UNDERWOOD." The other photo has three captions on the back. The first is hand written and states, "Kinner Airster for Earhart, c 3/23." The next caption is typed and reads, "Amelia Earhart's second plane built by Kinner aircraft in March, 1923. Built in Glendale." The third caption reads, " Amelia Earhart's second airplane was this Glendale-built Kinner Airster, c. March 1923. It was very much an experimental proposition. The engine was a Kinner-copy of the Wright L-2, forerunner of the Whirlwind, but it was fraught with eccentricities. It threw more oil than it consumed and vibrated excessively. Even so, it gave A.E. great pleasure to be a part of the development program. The experience gained from her flying helped Kinner build a better engine and by 1930 he was a leader in the field." Does anyone know what became of Kinner engines? Can anyone on the forum tell me if this info is new or just rediscovered?

True he will get an azimuth for his LOP but he needs an accurate altitude of the sun to PLACE the LOP. To get an accurate sun shot the sun needs to be between 20 and 70 degrees altitude and the ole I-ball will never get an altitude even close. What he CAN do as the sun just barely peeps over the horizon is get a great azimuth to reset his gyros and he needs to shoot the sun to get that. We don't want him turning the plane just to eyeball in a heading. Next, we would only know if the sunrise was dead ahead if we knew what course they were flying and we don't. Finally, you are correct that Fred needed to deal with refraction error but that's routine. Altitude is not going to make a whole ton of difference.

In principle, by observing and measuring the azimuth of the sun at sunrise, and comparing this reading to the correct date column on a table (reflecting altitude too), Noonan was able to determine the latitude (NS) of the Electra. It is not necessary to know the time of day to successfully accomplish this first step-- but it is necessary to have a sextant and a set of printed tables (azimuth/date/latitude/altitude) to consult. After this step, using a very accurate chronometer (to read the correct time of sunrise in hours, minutes, and seconds), consultation of another column on a table, based on pre-calculated times of day of progressive sunrise at a given latitude, would have given him his longitude (EW). One would assume that they were above cloud cover when they spotted the sunrise. The sun sighting is distorted by the atmosphere as the sun appears over the limb of the earth but there are techniques for compensating for this, including timing a wait until the sun is high enough for an undistorted view and then taking the angle and subtracting the wait time. To sum up, with a sextant, a good chronometer (which is a very accurate clock or watch), a relatively unobstructed view of the sunrise, and a set of printed tables, Noonan would have been able determine both his latitude and longitude within roughly 30 miles. He could have done some additional double checking against any nocturnal celestial sightings he might have taken earlier, combined with an estimate of distance (and bearing) traveled, calculated as a function of time and average airspeed. A line of position is a "sun line", directly related to the axis of the earth and the orientation of that axis to the sun according to the earth's position in solar orbit, along which the sun will rise at the same moment across all latitudes. On the morning of 2 July 1937 in the central Pacific, this line was approximately 157/337, irrelevant to latitude or longitude. As an absolute, it became a convenient known line which could be advanced by "dead reckoning" along their course to Howland. From Howland, this line extended at a bearing of 157 degrees to the vicinity of Gardner island). This means that on 2 July 1937 the sun rose at about the same time on both Howland and Gardner, but at a different azimuth (slightly more northerly at Gardner). Because their flight gradually progressed to a more northerly latitude, the anticipated azimuth of the coming sunrise would have increased slightly as they traveled along their route. As a matter of trivia, historically, the primary economic motivation in past centuries to develop really accurate timepieces was that knowing the time of day (or elapsed time over long periods) was essential to calculating longitude (EW) on long ocean voyages made by merchant vessels. I hope this helps-- and I welcome corrections on anything I've missed. william 2243 ========================================================================= Date: Mon, 20 Dec 1999 09:49:10 EST From: Randy Jacobson Subject: Re: LOP forever Sun shots (or stars, for that matter) never are done for azimuth directions (direction from north), but for altitude. At sunrise, one has three choices for times: upper limb, middle of sun, and lower limb to measure time of that limb breaking the horizon. The LOP direction is pre-determined by azimuth, and can be obtained from any almanac. The position of the LOP is determined by the time compared to what one expects based upon a dead reckon postion. Any difference moves the LOP back or forward to update your DR position. The same can be done for other times, but that does require a sextant/octant to measure altitude. ========================================================================= Date: Mon, 20 Dec 1999 09:53:46 EST From: Alan Caldwell Subject: Re: sunrise Vern asked: << Would not the sunrise be seen at the same azimuth, within the accuracy of observation, all along their route?

It is true the sunrise azimuth would be essentially the same IF their latitude did not change. Any change in latitude would have a corresponding change in the sun's azimuth. We don't know what their course was inbound to Howland. If their flight deviated from planned course because of weather (winds, storms, cloud cover) then their inbound course could vary greatly. Even more so if Noonan felt a need to correct back to course rather than set a new course direct to destination. Also the only part of their course we are concerned with as far as sunrise is concerned is from 6:20a to 8:44a. Otherwise it is dark. You are also correct that the sunrise moment would tell them where they were as to their east/west position -- but at sunrise that information is not accurate. Again to get an accurate LOP the sun must be between 20 degrees and 70 degrees altitude. At ten degrees the accuracy is OK for a reasonable position but not any great accuracy can be achieved until the sun is higher. I can see your reasoning that if the sun peeps up at 6:20a then they had to be ON or NEAR the line of LOP going through Howland because the table says at that time the sun will have an altitude of 0.7 degrees. But such is not the case. Perfect time to get an azimuth as just the tip of the sun's arc shows above the horizon but because of refraction and atmospheric disturbance the accuracy at that low altitude cannot be determined with significant reliability. Thus they could not get a speed line nor an LOP to advance. I also checked my maps and depending on whether they over flew Nauru or passed considerably south of Nauru and whether they came in over Howland or as much as 100 miles north or south of Howland their inbound course could have varied from about 64 degrees to as much as 97 degrees. And THAT we don't know. Making assumptions is OK for the sake of gaming out possibilities but not for much else. Your comment, "They were flying almost directly toward the point where the sun would rise and their latitude changed by only a couple of degrees during the last few hours," cannot be supported with the information available. Celestial navigation is highly precise in spite of inherent errors. Relatively small changes mean a great deal in fixing a position. You will note the azimuths in the table are in tenths though shooting to that accuracy is dubious. You can see that it is easy to make statements based on what we think, what we thought we read, or what someone else erroneously wrote. Unfortunately those statements take on a life of their own. Thankfully, Ric does a good job of getting us back on track as well as do the comments and questioning from each of the members. That's what we do well -- question each other. If I'm not mistaken what we know about Amelia's inbound leg to Howland is that it came from a westerly direction of unknown course, at an unknown altitude and unknown ground speed. We believe at some time and place between 6:20a and 8:44a Noonan was able to get a sun shot. DRing from a pre dawn star fix would NOT give the 157-337 LOP. We don't know whether they obtained more than one sun shot, obtained a moon shot or drift information. It DOES seem clear to me they thought they had an LOP going through Howland and they thought they were on it. Rough fuel consumption exercises indicate they may have had about 3 1/2 hours of fuel reserve at 38 GPH. On the trip to Hawaii Amelia indicated she could meter back to 20 GPH if she had to. The only point of this is that there is a reasonable chance they had fuel to make it to Niku. Keep in mind the fuel problem is far from being resolved and at this time is only an educated guess. With the LOP they had an almost certainty of reaching one of the Phoenix group but not the slightest clue how to get to the Gilberts without a latitude position.

It may well be possible to make it part of a separate charter from Australia, New Zealand or some other point of departure. Let say a charter (non TIGHAR) is organized for a group to spend a few days in Fiji. TIGHAR then charters the airplane from Fiji for its flight which returns to Fiji. The airplane is now used for the return of the original non TIGHAR group to the country of origin. All that the TIGHAR group pays for is the portion to and from Fiji and to get to Fiji what ever way they can work out individually.

Time relationships are best considered in terms of GMT. Sunrise for an observer on the ground at Howland Island on July 2nd occurs at 1746 GMT. An observer at 10,000 feet has a geometric horizon distance of 114.4 nautical miles. The sunrise terminator moves at 15 degrees per hour which, at or near the equator, corresponds to a speed of 900 knots. This means that a stationary observer at 10,000 feet will, assuming a clear horizon, see sunrise approximately 7.6 minutes earlier than an observer on the ground at the same geographic position. An observer 200 miles west of Howland will see sunrise approximately 13.3 minutes later than an observer at Howland, at the same altitude. To get the time of sunrise at 10,000 feet 200 miles west of Howland, subtract 7.6 minutes from the surface sunrise time, giving 1738.5 GMT. Then add the correction factor, 13.3 minutes, for an observer 200 miles to the west. This gives sunrise there at 1751.7 GMT, or 1752 GMT which is close enough for government work. Wherever Noonan was when he saw sunrise, he saw the sun at an azimuth of 067 degrees, and his sunrise LOP would be parallel to the 157/337 LOP through Howland. Noonan had plenty of time between his sunrise and arrival at the Howland LOP to take sun shots and estimate his ground speed and ETA at the LOP. Even though the Sun's azimuth was shifting counterclockwise with time, it didn't shift more than a few degrees between 1752 GMT and 1912 GMT, which would be the latest time of arrival at the Howland LOP. Consequently, his ground speed calculations were not significantly impacted by the shift in the Sun's azimuth, and he could accurately time his turn onto the Howland LOP. The sunrise calculation procedure is only slightly more complicated in the case where the airborne observer is known to have been at some position before sunrise and it is desired to know when he will intercept the terminator. In that case, one uses the relative closing speed between the observer's platform and the terminator to compute the sunrise differential. Bob ************************************************************************** From Ric So, if the sunrise from 10,000 ft 200 nm west of Howland is seen at 1752 GMT, then Earhart's statement at 1745 GMT that she is "approx. 200 miles out" can not be based upon an LOP established by observing the sunrise - OR - she's closer than 200 nm. How much closer? We're only talking a difference of 7 minutes. How far is she from Howland if she sees the sunrise at - say - 1740? Or what if she's at 12,000 feet? My point here is that the 1745 transmission may be a very important clue to where the airplane was at that time. Itasca hears Earhart at her regularly scheduled transmission times at 02:45 local (1415 GMT), 03:45 (1515 GMT), 4:45 (1615 GMT) but never gives any estimate of her position. Nothing is heard from her at 5:45 local (1715 GMT) but then at 06:14 local (1744 GMT) she comes on with her first request for Itasca to take a bearing on her. A minute later she says that she's "ABOUT TWO HUNDRED MILES OUT/ APPX." and begins whistling into the mic. Sounds to me like 200 miles is the magic number. Once she is that close she expects to be able to get the all-important DF bearing that will allow her to find Howland. The question is: Does the sunrise have anything to do with the 200 miles out estimate?

This is possibly caused by the rotational contact intervals being closer together at higher rpm, which would provide a somewhat smoother contact than the lower rpm would. This is not the same as a real sudden stop where the prop stops turning upon impact even though most power prop strikes are referred to as "sudden stops". The likelihood of damage is also determined by the particular model of engine/crankshaft in question as some are definitely worse than others for ending up as a non-serviceable part.

It would be interesting to learn what refraction tables or formulas were available in 1937.

I am under the impression that refraction is considerable for very low sights--for a sextant altitude of 0 degrees the refraction being about 32 minutes of angle at Sea Level, and about 22 minutes at 10,000 feet MSL. We have tables now to give us a prediction of refraction; maybe working from experience Noonan had a very good idea of what refraction correction to apply. ========================================================================= Date: Mon, 20 Dec 1999 10:52:11 EST From: Michael Lowrey Subject: T.A.T.

I would think that Noonan would be up front helping to sight the Island, probably with binoculars. Could he do all his navigation work in the front seat, or would he have to go back and forth from his place in the back? I heard from somewhere that he would have to crawl over the fuel tank to get up front; sounded like it wasn't real easy. Monty Barnett #2224 ************************************************************************** From Ric We really have very little information about what the aft part of the cabin was like following the repairs. Prior to the first world flight attempt there was plently of publicity about the rather elaborate "navigator's station" designed by Harry Manning and Paul Mantz. That set-up has passed into legend as the way the airplane looked, but there is no indication that it was retained by Noonan after both manning and mantz were out of the picture. Nobody seems to have taken any photos of the cabin area immediately prior to or during the second world flight attempt. We can only presume that Noonan had some kind of surface back there where he could spread out a chart. We do know that the fuselage fuel tank arrangement was unchanged. Crawling back and forth over the tanks between cockpit and cabin looks like it would be a bit awkward but not difficult. I'm guessing, but it seems reasonable that Fred would want to take his sunshot/observation from up front then go back to lay the lines on the chart and do the arithmetic to predict their ETA. Then, as you say, he'd want to be up front to look for the island. He should have plenty of time to do that.

Very true, but the story said both lifeboats were swept away, meaning everyone that got to shore did so the hard way, by swimming. Very, very unlikely they would try to swim with something as big and clunky as a sextant in a box. Ergo, the sextant found on the island was either washed up from the wreck of the NC (possible separating the box from the sextant and the inverting eyepiece, etc) or else it was scavenged from the NC at a later time by the local islanders, but I see no reason for them to claim to have found it somewhere else other than the wreck, unless there was some tabu associated with approaching the wreck. I find it very plausible that the sextant box found by Gallager would be from the NC because it is unlikely that the captain was able to take the sextant off with him. Considering that they knew where they were, they didn't need a sextant. They would, most likely, take only those things that would insure their survival until help could arrive. That's my story and sticking with it.

Besides, it's hard to explain how a wooden box would survive a fire. That means that IF the sextant box came from the shipwreck it almost had to go into the water at the time of the evacuation. It certainly seems possible that, even though Capt. Hamer had already gone for an involuntary swim, the box with sextant was placed aboard the second lifeboat and the sextant itself was lost when the boat capsized, leaving the wooden box to be washed ashore and later found by the mysterious castaway(s). ========================================================================= Date: Mon, 20 Dec 1999 12:59:11 EST From: Dave Bush Subject: Re: LOP Don't you think its time to LOP off this particular thread?

Seasons greetings to all, In response to Roger Kelley's of 12/19 questions about Transcontinental Air Transport, the Centennial History of the Pennsylvania Railroad by Burgess & Kennedy, 1949, says T.A.T. was launched in the spring of 1928. Purpose was to provide 48-hour service from coast to coast using rail travel by night and flying by day. Night flying was not indulged in except by some of the hardier air-mail pilots. The backers of the new company were Wright Aeronautical Co., Curtis Airplane & Motor Co., National Aviation Corp., the Pennsylvania Railroad Co. and a banking group headed by Blair & Co. of New York. PRR invested $500,000 for a one-fifth interest...Following the joint award of a coast-to-coast airmail contract to T.A.T. and Western Air Express, a new corporation, Transcontinental & Western Air, Inc. was formed for the purpose of unified operation and T.A.T. accepted 47 1/2 percent of the stock of the new company for its equipment and other assets, and was thenceforth a holding company. Cancellation of all the airmail contracts by President Roosevelt in February 1934 led to reorganization of TWA later in the year. The PRR retained its interest until 1936 when its stock was sold.

I think you're overplaying the fire. This wasn't an airplane fire, with everything going up in a big ball of flame; it was a big old burning ship, with lots of opportunities for stuff to go unburned because there wasn't enough oxygen around its location, it got wetted by the sea, etc. etc. There must have been enough of the (presumably wooden) decks left for Maude, the Kiwis, et al to get across the wreck when they tied off to it. I don't think there's any reason to think that wooden objects like sextant boxes couldn't have survived to be scavenged by the colonists. LTM (who's burning with interest in this) Tom King ************************************************************************** From Ric Here are Second Officer Henry Lott's references to the fire: "After a considerable time (following the grounding) I noticed smoke coming from the fiddley. I looked down in No. 3 (hold) and I could just see flames down below. I went quietly to the Engineers and told them. They went down below and reported that the ship was on fire." (After unsuccessfully trying to lower the port lifeboat) "By that time the ship was a furnace in the Engine Room and No. 3 hold....We had the intention of waiting aboard until daylight. She started exploding down below." Captain Hamer described it this way: "Shortly before 4 a.m. smoke was seen issuing from the engine room and in less time than it takes to tell the engine room, stokeholds, and number three hold burst into flames. Fanned by the strong winds it wasn't long before the vessel presented an alarming spectacle. Minor explosions were occurring at frequent intervals...." Examining photos taken aboard the wreck in 1937 and 1938 I can't see any fire damage to the deck nor can I see the striations that are typical of a wooden deck, but that doesn't mean it wasn't wood. About all we can say about the fire beyond the descriptions by the eye witnesses is that it was bad enough to motivate all of the crew to abandon ship into the teeth of a storm. LTM Ric ========================================================================= Date: Mon, 20 Dec 1999 19:33:49 EST From: Doug Brutlag Subject: Tropical vis, reenactment, cel nav from a jet, etc. Greeting to all AE sleuths. I just got home from a Carib trip & I get avalanched by all these emails-62 to be exact! Wow- we all got too much time on our hands! Anyway.... I flew a 757 to the carib this weekend. I was holding at a fix to the NW waiting for my turn to get into to St. Thomas. The humidity was much higher than normal(even for the tropics). A few small rainshowers in the area. I observed alot of scattered cloud cover and the visibility was advertised as 10 miles+. Holding at 3000 ft. 10 miles from my island target I could not see it. The vis may be 10+ on the surface but in the air it varied a few miles plus/minus. Lucky for me my airplane has 3 laser-ring gyro Inertial reference systems along with a flight mangement unit, 2 vor's, & 2 ADFs. For AE & FN to have missed seeing Howland which is much smaller than Thomas makes perfect sense although unfortunate for them. If they were searching at 1000 above the waves their prevailing vis would likely be even worse. I have no doubt whatsoever that FN was one of the best if not the best navigators in the universe at this time and if anyhone could have nailed a rock in the middle of the pacific no bigger than Howland he could do it. It must be understood by those who have not done cel nav or island hopped in an ocean enviornment that the danger of a navigation problem or missing your target this small was very great. Weather reporting then was crude in the civilized world but for their part of the globe not existant. Celestial nav can work very well but you still must be able to eyeball your target. It's accuracy for aviators was not as precise as it worked for mariner due to aircraft speeds, sight reduction methods, moving platforms, and equipment limitations to name a few. What's my point? Give Fred his due and a break at the same time. Put yourself in Fred's boots. If I knew the risks of missing my target in a pond as big as the pacific were that great, my backup plan would be to hit some real estate where my odds would be better to make a landfall and the Phoenix islands would be a very good (multiple)target. Fred could have also deduced a northly wind aloft that would aid them in their diversion to the SE-make their fuel reserve stretch a little further. Disagree if you wish, but my instincts go with Gardener. A 767-300ER for the reenactment? A possibility. Some problems though. It could certainly get the job done of going from point A to B with lots of range but it would be next to impossible to fly it anywhere close to Electra speed for the landfall & diversion. You would be carrying 10's of thousands of pounds of fuel to do that portion of the trip. Add that to the empty weight of the airplane, passengers, bags, and you could not slow it down enough. Even if you could, your fuel flow would go up exponentially (gear, slats,& flaps hanging out). I also see a problem of some of these island airports(i.e. Kanton, Tarawa, Christmas island) not being equipped or unable to service a wide-body aircraft. I personally would favor a prop aircraft. It could fly much lower & slower and do it much more efficiently. C-130 as suggested might be a good candidate. Got a few other candidates but prefer to research their performance & range first. I have shot celestial from a 767 though with an A-10 sextant. It can be done. You have to know what part of the windshields to shoot from for the least refraction error. There are curves toward the corners that will throw your sight off 20-40 miles. I have fixed the standard refraction error on a good observation at a -4 minutes of arc. Whatever you put together Ric, my gear is ready to go. Let's do it.

I agree. If you are abandoning ship with lifeboats, then the sextant is probably the most important piece of gear necessary for survival and navigation. If the NC folks hadn't made contact with another ship, and were ensured of rescue, then they might have to take to the lifeboats and navigate someplace where civilization exists. You can't do that without a sextant. Thus, sextant in lifeboats is one of the first orders of business in abandoning ship. It certainly is not the last thing to take! Sorry, Janet, but that is my $.03 worth (inflation, you know, is robbing us all!) Randy Jacobson *************************************************************************** From Ric For what it's worth, the preparation of the lifeboats for launching was done before the fire got bad.

Grooch then an Operations Manager for Pan Am in the late 30's commented about Fred Noonan's navigation skills. When describing the survey flights across the Pacific to Midway & Wake Island he writes quote" In the Clipper, (Fred) Noonan shot the sun every hour: his fixes agreed with the direction-finder bearings. (Captains) Sully & Tilton (Clipper Pilots) hit Wake Island on the nose". He is also described training navigators for Pan Am. In another section, Fred was descibed able to quote"shoot the sun standing on his head". Everything said about FN is entirely complimentary and reguards him as nothing short of a skilled professional. All the information of him written at the time says nothing negative. The alcoholism stories to me are pure unadulterated BS. You cannot have a problem as that and do the job of an airial navigator at all-and doing it with Fred's reputation for skill & accuracy-forget it! I think it can be agreed that he navigated the Electra very close to Howland Island judging from the strength of the radio transmissions. Factor in though fatigue, days of flying and crossing many time zones, and possibly fumes from all that 100 octane in the cabin could only compound the problems they were encounting. Working around petrol fumes gave me a big headache once and tylenol was not invented back then. ************************************************************************* From Ric Picky detail: While I certainly agree that gasoline fumes are no fun to work around, the notion that the Electra was plagued by that problem is another example of various authors blowing a single comment by AE way out of proportion. On the South Atlantic crossing AE complained that gasoline fumes made her sick, but that was because the tanks had been overfilled. And the gas used on the Lae/Howland flight was mostly 87 octane (not that it smells any different). ========================================================================= Date: Tue, 21 Dec 1999 08:51:59 EST From: William Webster-Garman Subject: Re: Sunrise > Mark Prange wrote: > Which altitude--the Sun's or the observer's--is referred to > in the table you mention parenthetically?

Itasca certainly had a ship's chronometer that was quite accurate but whether the clock in the radio room was set preceisely is another question. The only way I can thnk that we have to check is to compare their time notations in the radio log with Earhart's pre-stated radio schedule. She said she would transmit at quarter past and quarter to the hour. Itasca logs her transmissions at 0345 0453 (but this is almost certainly a delayed entry) 0614 0645 0742 0800 0843 Looks like they were pretty close. LTM, Ric ========================================================================= Date: Tue, 21 Dec 1999 09:33:14 EST From: Randy Jacobson Subject: 200 miles? 100 miles? Sorry, Ric, but someone has provided possible 'bum' information. At 1811GMT, AE says she was 100 miles out. If true, she was at 25.5'N, 178o, 15.4'W. Sunrise at that position was at 1755GMT, just about enough time between sunrise and the later radio report for FJN to work up the LOP. At 200 miles out, sunrise would be even later. At 10k feet elevation, there is an 8 minute advantage towards sunrise, so it would have been seen at 1748GMT. It is simply impossible for Noonan to calculate the fix, give AE the information in time for her to broadcast the 200 miles out at 1744GMT. Times are based upon middle limb of the sun, so a minute or so advance beyond above is possible if FJN was making measurements at the leading edge of the sun (upper limb). Based upon readings of all prevous FJN charts, it took him at least 15 minutes to work up LOP's into a fix. If FJN did sight a sunrise prior to 1744GMT, and worked it up so AE had a decent distance to go, then why was the next broadcast 30 minutes later state only 100 miles out? LTM, who never looks directly into the sun. Randy Jacobson ************************************************************************** From Ric I think we're all pretty much in agreement that the 200 mile estimate was probably not based on a sun shot. The Itasca radio log entry which has traditionally been interpreted as an estimate by Earhart that she is 100 miles out was recorded at 06:45 local (1815 GMT) - not 18:11 (not that it's any big deal). I agree that the timing suggests that this estimate could much more likely be based upon a sun shot and LOP calculation. However, there are two possible problems with that hypothesis: - If they're 100 nm miles out at 18:15 GMT and they have covered that distance at the time Earhart says "We must be on you.." at 19:12 GMT (57 minutes later) they're making only making 105 knots. I suppose that's possible if they've already made their descent down to 1,000 feet, they're playing it real conservative on the power, and they have a bit of a headwind. There's also the point that Earhart's scheduled transmissions can be conveying old information. - The original radio log entry looks very suspiciously like the appended notation " - abt 100 miles out" was not intended as a quote but was the radio operator's own estimate based upon the strength of the transmission.

I don't think so. None of the descriptions of the sextant box mention damage that would most likely be caused by tumbling in the surf - especially if it was severe enough to force the box open and eject the sextant. From other wooden instrument boxes I have seen, there is a pretty good latch or lock, and some device to secure the instrument inside the box. (Is that the case with the known sextant box?) Had there been damage, I believe that Gallagher, as thorough as he was, would have mentioned it at some point. Besides, it was used as a container to hold the other "pieces of evidence" being sent to the High Commissioner, so it couldn't have suffered much. That's my conjecture for the day.

The catches on the box are simple hooks and the device is not secured within the box. As for how beat up the box found by Gallagher was - I don't think we can draw any conclusions except to say that the numbers were still legible and the box was, as you say, intact enough to be used as a container. ========================================================================= Date: Tue, 21 Dec 1999 09:53:48 EST From: Jon Greenberg Subject: Re: LOP > Noonan's trade was a complex combination of science, skill, and art.

A signal strength of 5 means the Electra was very close to Itasca and therefore Fred's navigation was pretty much spot on! At Lae a few days before she found she could not get a minimum on the signal from Lae and thought it may be because the signal was too powerful and too close.

Same old sun you'd see anytime. ========================================================================= Date: Tue, 21 Dec 1999 19:05:16 EST From: Dennis McGee Subject: Sextant boxes This is long, so get a big cup of joe before you start reading. In June I inspected, at TIGHAR's request, about two dozen sextants/octants and their carrying cases that are part of the Smithsonian Institution's collections of navigation equipment. The sextants were formerly owned by Capt. P. V. H. Weems, a noted navigator of the 1930-40 era. Weems and FN were friends, and the reason for the inspection was to see if there was any link between the Weems collection sextants and the sextant box found by Gallagher on Niku. There were no obvious connections. In all, I inspected approximately 12-15 sextant carrying cases. Generally, the carrying cases were wooden boxes about 10 inches wide, 8-9 inches deep and 5 inches tall. They were all durable and well-constructed, but were far from indestructible. The construction techniques were strait forward, dove-tailed corners on all four sides with the top and bottom panels nailed on. The latches tended to be simple hook-and-eye or hook-and-post affairs and the hinges were generally a pair of one-inch piano-style on the inside back of the top cover. This technique, with few exceptions, was generally the same whether the manufacturer was British, American, Japanese, or German. The wood used for the boxes surprised me. I am not a woodworker, so I'm not qualified to identify definitely the types of wood used. However, generally (again, that word) the wood was wide-grained, light weight, light color, and about one-quarter to three-eight's inch thick. My inexpert opinion is the wood is pine, poplar or something similar. Personally, I expected heavier/thicker wood due to the intended purpose of the box. Some of the boxes were painted, some varnished, some stained, but the underlying composition, construction, and materials of the boxes remained constant, i.e.. light-weight relatively thin wood. These boxes were sturdy, but not would not survive deliberate abuse. As an example, if you dropped one of these boxes containing a sextant and its eye pieces etc. onto a hard surface, (steel or concrete decking for example) from a height of say 6-8 feet, I believe the box probably would be damaged. They were certainly adequate to survive day-to-day bouncing, jostling, bumping, etc. but they would not survive heavy hitting (a good solid kick for example), in my estimation. So, could a sextant box from the Norwhich City (if one existed) have made it ashore to Niku? Yes, if it was constructed similarly to the ones I saw in the Weems collection, BUT only if it were carried. The construction of the boxes are such they would have easily survived, I believe, being dropped overboard from a life boat by a sitting passenger (2-3 feet to the water) and may even survive being dropped from the deck of the ship itself. So it is possible the box could have survived entering the water, loosing its sextant, and being washed ashore. I believe also it is doubtful a box could have survived any sustained surf action, much less surviving being rolled up and down the reef during tidal periods. They simply are not that sturdy. Also, all of the boxes I saw were painted, stained, or varnished all of which would have suffered greatly under the harsh conditions of sun, sand, wind, and salt water at Niku. Gallagher makes no mention of his box having any weathering damage, suggesting to me it was in "relatively" good shape. The fact he could still read numbers written and stenciled on it suggests at least those portions of the box were protected from the elements. All of this suggests to me that Gallager's sextant box was deliberately brought to the island and did not arrive by happenstance. I would also guess that its previous owners on the island made it a point to keep the box protected and intact for whatever use it served. LTM, who's winded at the moment Dennis O. McGee #1049 *************************************************************************** From Ric This same argument says the the box is not just a piece of flotsam that happened to wash ashore after having been lost in a mishap somewhere else. No. I agree with Dennis (Lord help me). The survival of the numbers on the box, and of the box itself, strongly suggest that is was deliberately brought ashore and not all that long before 1940.

If they were in the area of Howland they could be on either the north or the south with no way to know which was correct. The only thing they could know was that heading south on the 337 line would take them to some Islands eventually". The whole point of my questioning is not what they would have done once they found themselves on the line between the islands, but rather if they were on the line at all. If they were in fact in that position, then the 157 degree heading would take them to only one island, they would miss the rest of the Group by hundreds of miles. They would have to over shoot Howland by two hundred miles to have the 157 degree heading take them to the main group of islands. Since my questioning began on this point, there have been over 40 posts explaining what an LOP is, the time of sunrise, cloud cover, surface visibility quote after quote from some of the best pilots and navigators in the business. If I missed the post which said,"I guarantee they were north of Gardner Island on a bearing of 337 degrees, less than 300 miles range for this reason. . . . " please repost it. Don J. ************************************************************************ From Ric Hope springs eternal.... 1. There are no guarantees and no one ever suggested that there were. The best we have are hypotheses based upon (we hope) an intelligent assessment of the available evidence. 2. AE said they were "on the line 157 337." We take that to mean that she, and presumably Noonan, believed that the aircraft was on the 157 337 sunrise LOP advanced through Howland and, coincidentally, through Baker and Gardner. 3. The strength of the radio transmissions heard by Itasca indicate that the aircraft was probably very close, almost certainly within 100 miles. 4. Noonan certainly had the expertise and probably had the wherewithal to establish such an LOP with considerable accuracy. We, therefore, conclude that the aircraft was probably where Earhart and Noonan thought it was - that is "on the line 157 337" passing through Howland, Baker and Gardner. 5. Such a line, if followed in the 157 direction, provides the proverbial "highway in the sky" to land. To abandon it to head for the Gilberts or the other islands of the Phoenix Group would be foolish in the extreme. We do not think that Earhart and Noonan were foolish in the extreme. 6. Quite clearly, the aircraft did not reach Howland or Baker. Therefore, if Earhart and Noonan were where they said they were and following the most intelligent course of action to insure their survival. they must have been south of Howland and Baker and proceeding 157 toward Gardner. In short, while it is of course possible that something else happened, the available evidence argues strongly in favor of the flight following a course that would bring it to Gardner. The building body of physical, documentary and photographic evidence that the flight did reach Gardner greatly reinforces the above interpretation of the navigational evidence.

It also could be that at the time AE said 100 miles out (1815GMT) and "must be on you but cannot see you" (1912GMT), that she had already reached the LOP and was moving north and south on it when she had broadcasted. ************************************************************************* From Ric If she had already reached the advanced LOP at 1815GMT why would she say she was 100 miles out? To me, the 1912GMT "We must be on you but cannot see you" message makes the most sense if they have just recently reached the advanced LOP and have looked around without seeing any islands. Noonan may even have had time to recheck his arithmetic ("We MUST be on you..") They've been trying in vain to get Itasca to take a bearing on them all during the run up to the advanced LOP. Now they've reached the line and there's no island there. Getting some DF information is now of paramount importance and this is when Earhart starts thinking about using her loop. At 1928GMT she asks for a long count on 7500. Noonan knows that they can only afford to run up the line (337) for a little way and he probably has AE fly that course (348 magnetic) while she tries to use the loop. By the time AE makes the final transmission heard by Itasca at 2013GMT, Noonan has had her reverse course to 168 magnetic. Earhart may not entirely understand what Noonan is doing. She may be reading the phrase "We are on the line 157 337" from a note Fred has handed her in the deafening cockpit. Her subsequent comment about "running on north and south line" or "running on line north and south" are probably her own general descriptions of what she has been doing.

Now imagine a splotch of open grass in a remote corner of one of those airports. Howland Island would fit into that. One benefit of a TIGHAR flyover of Howland would be that the sponsors would be able to see first hand what a tiny little target that island presents to someone in the vicinity trying to find it, especially without a working DF. Also, the idea of watching the sun slip over the horizon on July 2, and seeing first-hand that a course perpendicular to that (67 degrees plus 90 degrees equals 157 degrees) leads straight to the vicinity of Niku could greatly reinforce the compelling nature of the the LOP available to Earhart and Noonan when they couldn't resolve Howland from all the cloud shadows below them that morning. Preaching to the converted? Probably, and personally I have no idea if the idea of a re-enactment is economically feasible, but the experience would certainly be educational for most people on the flight.

On any tropical Island in my home area, if you left the box on the sand even in the shade for over a year, it is very inlikely that you'd recognise its original purpose, let alone read any stencilled marks especially if it had been doused in salt water. If it came from the surf, chances are it was lying in the water for a while, then in the tropical sun on the shore at the tideline as it was gradually washed higher up with each tide until it was found and brought under the tree. Of course it could have been collected right away by a Norwich City survivor, but it would still have suffered a couple of years of tropical deterioration before being found. Bearing in mind that the "Niku Jungle" picture on the web site shows what looks almost like a typical piece of our local scenery.

In my previous posting I was expressing a *genuine* interest in Dave Bush's comments about the possible origins of the sextant box, and certainly did not intend to appear to disagree. My only point was that I didn't believe that Capt. Hamer was attempting to leave by the port boat at that time, and consequently doubt that it had been 'equipped' with anything. (There was no 'hidden message' behind my remarks.. honestly!) For what it's worth, I agree with Ric in that *if* the sextant box originated from the NC, then it would likely have got to Gardner in a manner such as he describes, i.e. after originally being placed the starboard lifeboat. I'd go further to express my personal belief that the probability of anyone carrying anything during their reach for safety is unlikely. Anecdotal accounts support the available official documentation in stating that many of the survivors felt the need to discard boots and clothing to aid their swim ashore. I suspect that they didn't much care for any possession at that particular time and were exceedingly grateful to find what had been washed ashore.

We theorize that they made a reasonable safe landing on the reef flat at low tide mainly because of the post flight radio transmissions and because Lockheed said that in order for them to have made those transmissions they had to be on land and to have one engine running. But I still find it very hard to believe that The entire Airplane on the reef flat being tore up by the wave action went unseen or unrecognized by the visitors just a very few months later. Trying to work this theory so it would fit leads me to believe that possibly there was not that much aircraft debri on the reef flat to begin with. If it wasn't for the radio transmissions I would think that they crashed on the reef its self and that a good portion of the aircraft ended up on the ocean side of the reef, under the turbulent waters, and is still there. We don't know when and if they arrived at Gardner, if it was high tide or low tide. What if it was high tide? How would they try to land then? Aircraft parts like a wing and fuselage were seen on the reef flat and possibly the dot and the dash is from Earharts plane. But no report of much more in that location. I can only think of two possible ways to land at high tide to fit the evidents and witness accounts that we have, [except for the radio transmission reports.] At high tide no way would be safe, but they wouldn't have much choice. One is to belly land on the reef flat in the 4-5 feet of water of the surf. This attempt could of ended up on the reef where much of the plane might still be, under water even at low tide. Or she could of tried to make a direct approach straight in from the ocean, just north of the ship wreck, trying to ride the surf in to the beach, but hitting short and hanging up on the reef. I know all this is wild, but I am trying to make reports that we have fit, and to propose that the lack of aircraft parts found might be due to much of the plane being out of sight and in a very hard to get at place on the ocean side of the reef, under water. Of course this theory is way off if Amelia did make radio transmissions two days after July 2. Unless Lockheed is wrong, or she was able somehow to turn an engine out on the reef. Or if the transmissions heard were all hoaxes and mistakes. I don't know much about the radio stuff back then but there were a lot of ships and planes looking for her and a lot of radio communications among them. I wonder if some of the radio signals they thought might of came from Amelia, actually came from the seachers communications in the area? Happy Holidays Everyone. Monty Barnett #2224 ***************************************************************************Fro m Ric Some of the alleged post-loss signals probably were misunderstood messages from the searchers themselves.

OK, let's try this again. At 1742GMT, Earhart says "200 miles out" At 1811GMT, Earhart says "100 miles out" At 1912GMT, Earhart says "must be on you but cannot see you" It takes less than an hour to transit 100 (statute or nautical) miles. Thus, if AE was really 100 miles out at 1811GMT, then she must have arrived at the LOP passing through Howland prior to 1912GMT. Between that time of arrival on the LOP and 1012GMT, she must have been doing something, most likely flying north and south on the line of position. One cannot arbitrary state that AE arrived at the Howland LOP at 1912 GMT, simply based upon her broadcast schedule. ************************************************************************* From Ric I have no argument with that except that I think you mean 1912, not 1012, and you have the other two times slightly wrong.

Yet, they raised a million dollars at the drop of a hat and start a search in the opposite direction. It would seem that a million dollars would equip and support a team on Niku for a heck of a long time. I'm not trying to be facetious here, but just think about it. What is it that they don't know, or maybe I should ask, what is it that we don't know? Don J. ************************************************************************* From Ric 1. Dana Timmer made up his mind that Elgen Long is right at least eight years ago. What on earth makes you think that anything we put on our website would influence him at all? 2. Elgen Long has (finally) published his explanation of how he reached his conclusions and we feel that it is deeply flawed. Not everyone agrees with us. That's okay. 3. Dana Timmer did not raise a million dollars at the drop of a hat. He says it took him eight years to find his "investors." He did it by acquiring the title to the airplane and turning his search into a treasure hunt. That's not the way TIGHAR operates. We have conducted our investigation publicly and solely in the interest of history and education. 4. In the course of our 12 year (to date) investigation TIGHAR has raised, and spent, something over 1.6 million dollars assembling the information we have posted publicly on the website (plus much more that we haven't gotten to yet).

I think the perfect airplane for the reenactment flight would be the Lockheed L-1011 model 500. This is the long range shortened version of the standard L-1011. We can simply pretend it is the Lockheed 10 (mark out the 11). It has the range and the extra engine for over water safety and it is a great airplane. Finding one available for charter work might be a problem however.

The strength of the radio transmissions heard by Itasca indicate that the >aircraft was probably very close, almost certainly within 100 miles. I wasn't going to post on LOP again, but this one is a problem. I trained as a radio tech in the Air Force. I also fly (though not as often as I'd like, and not commercially). We use a signal strength of 1 to 5 and a similar readability scale. Is there anyone on the forum that can say for certain that such a scale was used on Itasca. If a 1 to 5 scale was used I doubt very much that AE was anywhere near 100 mles distance from Howland regardless of what frequency she was on. A readability of 5 and signal strength of 2 or 3 could put her almost anywhere with a good radio and antenna, given nice atmospheric conditions and different times of the day. Mid morning, a signal strength of 5 regardless of readability means that "must be on you" is pretty accurate. Once again none of us were there, so we don't know the power of the set. I have sat in IDA on VHF and talked to the tower from a 10 miles away and been given a signal strength of 3. The other thing to think about is that the antenna ran lengthwise down the fuselage. When Itasca got a reading of sig strength 5 AE was probably passing them right at that moment, either overhead, or more likely to one side. Of course that might suggest that AE was heading directly towards Itasca for most of the morning and the antenna was too directional to receive Itasca's signals very well. (AE couldn't get a "null" on her DF antenna, but she unintentionally had one of the comms one). More speculation , but that's all we can do really - come up with theories and discuss them... RossD *************************************************************************** From Ric A little knowledge is a dangerous thing - and when it comes to the Earhart case none of us have much knowledge and we're all dangerous. Signal strength judgements are very much a part of the information recorded in the Itasca radio log and it was the opinion of the authorities at the time that the strength of the signals received indicated that the aircraft was probably within 100 miles. We know that the Electra's transmitter was rated at 50 watts but that the actual output of the aircraft's antenna array (a dorsal vee) was much less than that. Just how much less is presently being researched by Bob Brandenburg through computer modeling.

They all show a wide expanse of coral rubble around the island. In most of the pictures it (scaled agaist the NC) is wide enough to land on. That's where I'm going to land, despite the drag on the U/C. I want to land somewhere where the tide won't reach me for a few hours... And where holes on the reef won't tear my U/C off (since I can't quite make out the exact condition of the surface of the reef as I overfly it.

RossD ************************************************************************** From Ric The tide is high at Gardner and the tide is low at Gardner with the same frequency that it is everyplace else. When the tide is high the water on the reef is, on the average, about four feet deep - way too deep to land in. When the tide is low the reef is dry and it's easy to see where it's smooth and where it's not. A hypothesis that requires a landing on the reef, by definition, requires that the tide be low or very nearly so. There is no way to know for sure what the tidal state was at Gardner around noon on July 2, 1937 (Trust me on this.

By that I mean exploiting the adventure as well as possible before the "give up we couldn't find it" point comes.

Changing to a high airspeed would have really messed Noonan up. Alan #2329 *************************************************************************** From Ric It's a given that the 200 and 100 mile estimates can't both be right if taken literally. One of the problems with trying to interpret what Earhart said is that we tend to dissect individual messages without regard to the context provided by all of the messages. At 1745 the entire log entry is: WANTS BEARING ON 3105 KCS//ON HOUR// WILL WHISTLE IN MIC ABOUT TWO HUNDRED MILES OUT// APPX//WHISTLING//NW A half hour later at 1815 the log entry looks like this: PSE TAKE BEARING ON US AND REPORT IN HALF HOUR-- I WILL MAKE MOISE (sic) IN MIC - ABT 100 MILES OUT She almost certainly did not say "IN HALF HOUR" but rather "ON HALF HOUR" which would be her next normal listening time. But Itasca, contrary to AE's instructions, was using local time. For them, the message came at 06:45 so the reference to "half hour" didn't make any sense. The "- ABT 100 MILE OUT" entry is clearly a later addition to the log becuase the platen is not aligned with the rest of the message. It could have been added 10 seconds or 10 minutes or 10 days later. There's no way to tell for sure, but I don't think it's something Earhart said at all. I think it's the operator's own estimate of her distance based upon the strength of the transmission.

Bellarts has it at 1815GMT (all times converted to GMT, of course!) The 1745GMT AE transmission is first recorded at 1742GMT by the non-Leo G. Bellarts radio transcript, again at 1743 GMT. Bellarts has it as 1744 to 1745GMT. While we both agree that Bellart's version is more contemporaneous (it is the raw, uncorrected version), one must give credence to the other record as far as times are concerned. I doubt that anyone would deliberately change the times of transmissions forward/backward or to match the two radio log versions. Both radio receiving stations aboard ship were trying to jot down what AE said. ************************************************************************ From Ric By the non-Leo G. Bellarts radio transcript I take it you mean Warner Thompson's "Radio Transcripts Earhart Flight" compiled later and O'Hares notations in the other Itasca radio log.

What makes Elgin Long think he's even going to find anything left of the Electra if it turns out that it did take the Nestea plunge into the Pacific 60+ years ago? The Titanic has been in the drink for 85 years disolving away at such a rate that experts say in 70 years or so that it will be gone just like an alka-seltzer. Granted it was made of iron & the Electra aluminum. Comparing the two metals, the mass, weight, & density, the Electra in my mind would have become metal fizz a long time ago. Same salt water-different ocean. I also thought I saw some mention that the airplane metal was not zinc-chromated-more bad news. Bob Ballard only looks for sunken ship. Who are they hiring with what equipment to do this job? Doug B. *************************************************************************** From Ric Elgen Long is a paid consultant to Nauticos (formerly Meridian Science). They're not doing anything right now except hoping that NOVA finds a sponsor for them and that Timmer doesn't find anything. Dana Timmer and company hired Williamson Associates of Seattle to perform the remote-sensing search that has just ended with some possible targets. Both Nauticos and Williamson are search technology companies, not metals conservators. That aluminum airplanes in deep salt water can survive relativley intact for over 50 years has been amply demonstrated. The problems start once you disturb them. Over the years the chlorides in the sea water actually become part of the alloy, making it extremely unstable in a more oxygen-rich environment.

Finding a Lockheed L-1011 should not be a problem. There are quite a few in Ireland waiting for charter work. The problem may be their age. Ask Virgin Express about their experience with one they chartered in Ireland last year. At the peak of the holiday season (besides scheduled services from Brussels, Virgin Express also flies charters to the Mediterranean) it broke down several times, causing angry comments from passengers and getting headlines in the newspapers. The cause was a broken fuel pump in no 2 engine. It was repaired. Then it broke down again. Rolls Royce sent some mechanics over to Brussels to replace it. Then the engine had a tail flame when it started up at the tarmac and everybody had to be evacuated. Then the Belgian civil aviation agency grounded it, saying they took that measure "before it crashes". The newspapers went wild over it and Virgin Express ended its contract with the Irish and swore never to charter an L-1011 again (Virgin Express is a well-reputed and succesful Brussels-based low-fare airline with a fleet of 16 brand new Boeing 737-300/400 but in need of large aircraft from the charter market during the summer holiday season). Ric might not have serious when he suggested a Zeppelin might do the job and I was not really serious when I reminded there were again Zeppelins availabe today. But on second thought I think the Zeppelin NT007 might indeed be right to do the job. Ric thinks at 70 knots and an endurance of 14 hours it would only get from Fiji to Niku. Well, can't they refuel ? At Canton perhaps ? Or indeed on any other tiny island big enough to hold a few fuel drums ? After all they don't even need an airfield. They could even refuel from a tanker at sea. Technically it should be feasable. I think the problem might be financial. Positioning the airship at Fiji would take a flight around half the world from Germany (at 70 knots). Might be time consuming and therefore expensive. Still I think it's worth asking them if it can be done and what it would cost. Tehy have set up an organisation who does their marketing for just this kind of operations. Maybe they give TIGHAR a good price to get publicity.

If a lot of things. LOCKHEED ELECTRA 10E FACT SHEET (From: http://wwwedu.ssc.nasa.gov/htmls/tseierc/electra-fs.htm ) ------------------------------------------------------------------------ Number Produced 15 Number Existing 2 Engines 2 Pratt & Whitney Wasp S3H1 Wing Span 55 feet Wing Area 458.5 square feet Body Length 38 feet, 7 inches Body Height 10 feet, 1 inch Empty Weight 6,454 pounds Loaded Weight 15,700 pounds Maximum Speed 202 mph (at 5,000 feet) Cruising Speed 90 mph Rate of Climb 1,140 feet per minute Service Ceiling 19,400 feet Normal Range 810 miles -------------------------------------------------------------- Scenario: Amelia and Fred have been flying all night. Fred calculates that they are only 200miles from their destination. They are in radio contact with Itasca. They are tired. They still have over 4 hours of fuel. Perhaps Amelia decides to open the throttles for a half hour and get within 100 miles more quickly so they can concentrate on the DF. Then around 100 miles out where they should have a clear signal, she slows down as they begin to try direction finding. Having said that, they would have been talking "nautical miles" so her 200miles was really 230 "statute miles" If she pushed the Electra it was apable of 202mph. (100 miles in half an hour) Now according to the fact sheet below the Electra's cruise is 90mph. I have a hard time believing that it cruised at 78kts. I think it is much more likely that the sheet is talking 90kts cruise. That gives us a 202kts maximum speed and there we have our 100miles in half an hour! On the other hand, the fact sheet might be literal in that it quotes statute miles per hour. It can still be done. My high school math tells me 202mph is about 175kts. So if she opened up to 175kts in no wind conditions, she would cover 84miles (nautical) in half an hour. 100 nautical miles would come up in 34 minutes and that is not far off half an hour. Now, a "force 2" breeze is 4-6kts. (4.5-7mph) IF the wind was similar where she was, and IF she had that BEHIND her (and we don't know if she did), her 175 kts could be around 180. At 180kts, 100nautical miles slips by in 33 minutes. Not much difference, but closer. Perhaps she wasn't flogging the Electra, but had a 20kt tail wind up where she was (probably 5000ft at 200 miles). 155kts plus a 20kt tailwind (very common in the tropics and not necessarily able to be detected by Itasca) would give her 175kts ground speed and still keep her pretty close to the half hour for 100 miles (nautical or statute). In the unlikely event that she reported statute miles she could do 100 miles in far less than half an hour with ease. So 200miles out at 17.44 - 100 miles out at 18.15 - could be done comfortably and might cost them some fuel, but they had heaps. Even if they doubled their worst planned consumption it would only cost them 26 gallons extra (half an hour of their 4-5 hour reserve). The next 100 miles could really take about an hour if they slowed to just above economical cruise (90kts) say to 100kts. If Amelia stuck to recommended in flight settings, she should have had 320 gallons left at 17.44GMT (enough for about 6.2hours at worst planned fuel flow and almost 8.45 hours at best flow). In that case, she should have had 260 gallons left at 19.12GMT (enough for 5 hours at worst planned fuel flow and 7.2 hours at best flow). If she did in fact do the 100 miles in half an hour, she may have burned up to half an hour extra out of her reserve fuel. That would still put her near Howland with 4 to 5 hours fuel available! Beetling around at 1000ft for an hour searching, she used at least 50 gallons (she would have the mixture rich at low altitude). This will leave her with 170 gallons at 20.13. At 50gph she still has over 3 hrs and 270 miles available to her. If she pulls back to economical cruise and leans out a bit she could extend that. So 100miles in about half an hour is not beyond the realms of possibility even without using the maximum speed of the Elecrtra, and it would not kill her chances of still having sufficient fuel to get to the Phoenix group. RossD ************************************************************************** From Ric Uh, Ross? The spec sheet you cite (linked from The Flight of the Finch website) is dead wrong. According to Lockheed publication EE1135, revised 5/1/36, the cruising speed of the standard Model 10E was 189 mph at sea level, 197 mph at 5,000 feet, and 205 mph at 9, 600 feet: in each case using 412 h.p. per engine (75 percent power). Economical cruise speeds, using 350 h.p (65 percent power) are correspondingly lower. None of these numbers has much to do with the way Earhart flew her 10E Special. She flew at 150 mph using power management profiles specially provided for her by Lockheed's "Kelly" Johnson (see http://www.tighar.org/Projects/Documents/Kelly_Johnson.html) If you really want to find a way to make NR16020 cover 100 nm in a half hour all you have to do is speculate that, during that time, Earhart descended from 10,000 feet to 1,000 feet by leaving the power at cruise, trimming nose down, and letting the speed build up. LTM, Ric ========================================================================= Date: Thu, 23 Dec 1999 11:02:29 EST From: Doug Brutlag Subject: Cloud Cover-Octas In answer to Ross's question on the term "octa's". It is a meteorological term, part of a guideline developed by the ICAO(International Civil Aviation Organization) to describe cloud cover. Actually spelled "oktas", it mean cloud cover in eighths. One okta is 1/8th sky cover. Numbers from 1 to 8 describ the amount of cloud cover with 9 meaning obscurred sky. It is also followed by two letter cloud type code-Ci meaning cirrus, Cu-cumulus, ect. Ceilings are not explicitly indicated by any special symbology. A ceiling is considered either the lowest layer of clouds that cover 5/8th or more of the sky, or an obscuration. If you see CAVOK it means "ceiling & vis ok"-horizontal vis is 10 km or better, no clouds observed below 5000 ft. or below the highest minimum sector altitude(whichever is higher) and no other clouds or obscurations present. If there are no clouds and CAVOK not appropriate they use the term "SKC"(sky clear). That having been said, I do not think the ICAO was formed back then. Met reporting was very crude then and the US only elected to switch to ICAO standard a few years ago. I hope this helps. Happy holidays Ross & all the rest of the AE sleuths.

The key to understanding the discrepency of time and distance of the 200 and 100 miles out is that Earhart never (I repeat never) provided a time and position for her position reports. Based upon analysis of the Oakland to Honolulu crossing, all reported position reports were dead reckon projections, based upon course/speed and a celestial fix, and basically represented the latest projected informatoin provided by the navigator. These positions were not the position at the time of reporting, but were up to 45 minutes prior to the radio transmission. Everyone speculates that the navigator gave AE a position update for radio broadcast just prior to the schedule, but that is not the case at all. So...AE's reported position of about 200 miles out may be 15-30 minutes old, as is the 100 miles out, but probably more recent than the former. Thus, the time difference is more like 45 minutes, not 30. ************************************************************************** From Ric Can't argue with you, but sure makes you wonder what she thought she was accomplishing. ========================================================================= Date: Thu, 23 Dec 1999 11:18:34 EST From: Randy Jacobson Subject: Re: Entertaining passengers on reenactment flight I guarantee all of the forum members that you DO NOT want to hear me sing: I am quite tone deaf. ========================================================================= Date: Thu, 23 Dec 1999 11:25:21 EST From: Doug Brutlag Subject: Apologies To Ross D.

LTM, Ric ========================================================================= Date: Thu, 23 Dec 1999 11:43:59 EST From: Tom MM Subject: 157 Alternatives In yesterday's digest you assert that "Such a line, if followed in the 157 direction, provides the proverbial "highway in the sky" to land. To abandon it to head for the Gilberts or the other islands of the Phoenix Group would be foolish in the extreme." I think that this overstates the case somewhat. Once the turn is made on the 157 LOP, there is basically nothing but dead reckoning to get you the 350 NM +/- to Niku. Opportunities to verify that you remain on that LOP are tough to find and exploit - further sun shots will yield LOPs, but not prove that you remain on the 157 course. You are at the mercy of cross winds, compass/gyrocompass errors and piloting "error", which can be considerable. Not a done deal at all. An additional sun shot near Niku would help, but it will take some luck to hit dead on. Very similar to finding Howland. As to abandoning the 157 line to head for other islands in the Phoenix group - from a pure navigational standpoint, there is no reason not to apply the very same sun LOP technique that is used to support the Niku alternative to ANY other island in the Phoenix group. For example, after searching the 157-337 line for some time, they could have decided that their best chance of making landfall of some kind would be to head for an island near the eastern side of the Phoenix group with the idea that the cluster of islands would backstop their navigation. They would then head in that direction (I'm not picking an island in order to keep this conceptual), based on Noonan's best estimate of their present position, right or wrong. As soon as practical, Noonan will take another sun shot - this time the LOP will lie somwhat more E-W than the 157-337 LOP. Noonan then advances (or retires) the new LOP thru the island(s) of choice. They fly to the advanced LOP, turn, and are now headed (again with DR) for their desired destination. In principle, very similar to following the 157 line toward Niku. The point of the above is not to "knock" the Niku hypothesis, but simply to illustrate that there are actually several reasonable navigational scenarios. Using similar reasoning, one can construct a (reasonable from a purely navigational standpoint) scenario that also includes the Gilberts using in flight sun LOP's or sun-moon fixes. You don't have to know where you are at the start, but you need to be able to at least get some sun shots in along the way. As interesting as the nav aspects of the flight are, I have shifted to thinking that the real guts of the mystery lies in the fuel endurance issue. With enough fuel, many things are possible. Once the fuel endurance analysis is out (how is it coming along?) it will hopefully be possible to screen out many options on that basis. Regards, Tom MM ************************************************************************* From Ric Your point about following the 157 line by DR is well made. The biggest reason I can see for NOT abandoning the 157 LOP in order to duplicate the exercise in a search for some other island in the Gilberts or Phoenix is that the 157 LOP is the ONLY one that includes the place they really want to find - Howland. I don't think that at any time they said "Well, the heck with Howland. Let's just head down to Gardner." I think they said, "Let's do the only thing that might bring us to Howland and, if it doesn't, will still get us to land of some kind." On our fuel analysis: we're still searching for a qualified aeronautical engineer to put on the team. I'd also like to recruit someone from P&W who worked with Finch.

I wasn't going to make any more posts until after I returned to from my Christmas Holiday, but in checking the mail one more time before leaving I see that the LOP thread is still alive and well. I thought we weren't sure the 157/337 line was an LOP. To me it seems the line is just a 90 degree turn, left and right from the assumed 067 degree inbound heading to Howland. As we know, the Azimuth of the sun at sunrise was 067 degree at Howland that day. Maybe a coincidence that is just trying to confuse us about what the 157/337 line really is. I think is is safe to say that they were not over, or abreast of Howland at sunrise, so therefore they must have pre calculated that "Line" early on. If they were able to get a sun shot, when the sun was higher I would think they would have stated the revised LOP and it would not have been 157/337. . . right? At about 7:30, it would have been 156/336 and so on as the day progressed. Would they have advanced an LOP based on the sunrise time at Howland or their ETA over Howland? At their ETA over Howland, the sun LOP would have been about 155/335. . . right? > I don't think that at any time they said "Well, the heck with Howland. Let's > just head down to Gardner." I think they said, "Let's do the only thing that > might bring us to Howland and, if it doesn't, will still get us to land of > some kind." I would think that would only work if they were in fact on a Howland sunrise LOP 157/337 and not on a line 157/337 based on DR and advanced from some point far to the west. They thought they were close, I can't imagine them turning south and flying for some three hours in a straight line, hoping to hit the only island in the Phoenix Group that was possible. Sure there was McKean, but I can't imagine AE saying, "I don't like that one, let's look farther south". Don J. *************************************************************************** From Ric Where did you get the idea that their assumed inbound heading to Howland was 067? If they were on a straight course from Lae, with no corrections enroute (not too likely), they should have been on a magnetic heading of 068 degrees (77 degrees True) according to the charts prepared for Earhart's first world flight attempt. What heading they were actually on by that point in the flight is anybody's guess. We do know that the sunrise was at 067 and that Noonan knew that, and that the first LOP he could get after dawn was 157/337, and that such a line advanced through Howland provided three other islands for possible landfall. In short, we are as sure as we can be under the circumstances that the 157/337 line referred to by Earhart in the last transmission heard by Itasca is the sunrise LOP. Nothing else makes any sense. ========================================================================= Date: Fri, 24 Dec 1999 09:56:14 EST From: Ross Devitt Subject: Re: 157 Alternatives Wouldn't AE be flying a magnetic heading?

Earhart never says anything about what heading she is flying except a vague reference to running on a north and south line. Her statement that "we are on the line 157 337" is probably being read off a note handed to her by Noonan. The magnetic variation in that area in 1937 was 9 degrees East.

With the sun at an azimuth of 67 degrees and it is still morning so the sun will be off the left wing about 90 degrees off the nose depending on actual heading.

"Variation East, Magnetic Least" South of the equator. My Jeppeson CR2 has a big "E" marked over the W under the wind scale to remind my son not to use the MagVar scale as is taught in the instruction manual. Our var is 8.5E so we use 8. If I use the scale for the US I get 157 var 9E=166. If I used that as a mag heading I'd finish up lost (more often). South of the Equator we SUBTRACT an East Variation. That makes 157=148 Mag. Now the tricky part. Howland is almost ON the equator. Which did they use for Howland? What happens when they cross (In a few minutes) to South of the equator? (In practice not a lot for the first part of the trip, but as they get further south, that 18 degrees takes on some sort of meaning.) They would ave been subtracting the variation from Lae to Nauru, but what did they use on the equator? Did they FN remember to change from 166M to 148M once he was below the equator? (He was a navigator, so I thik he did). So I'd suspect that they were flying "148M". Not that it made any difference to landfall. 166M Would put them on 329/146 on the chart. RossD (who stands ready to be corrected - but DOES have to pick Mag from True South of the Equator). ************************************************************************** From Ric No, Ross. If you're converting from Magnetic to True "East is Least and West is Best" no matter which side of the equator you're on. In this case we're talking about converting True back to Magnetic so the process is reversed, hence we ADD 9 degrees to the True heading of 157. ========================================================================= Date: Mon, 27 Dec 1999 13:04:21 EST From: Ric Gillespie Subject: Mystic Musings Over the Christmas weekend I indulged myself by playing a computer game that I had picked up several months ago but hadn't had time to even look at. It is, supposedly, a very popular fantasy detective game called MYST and I wonder how many forum subscribers are familiar with it. You travel to a small, remote, uninhabited island strewn with the abandoned structures of the former inhabitants. On one side of the island is a wrecked ship. By carefully inspecting and deciphering the clues on the island you unlock its secrets and are transported to various "ages" in the island's past where you find more clues to ultimately solve the island's great riddle. Sound familiar? MYST is actually an excellent training device for the scientific method of inquiry. You collect data, form a hypothesis, and test it. If your hypothesis is correct you are rewarded by obtaining access to another level of mystery to work on, but if you don't pay close attention or if you just flail around in unfounded speculation, you get nowhere. But beyond that, I found it interesting that the game's creators chose an island as the setting for the mystery and it got me thinking about islands as cultural symbols of mystery and escape. Atlantis, Bali Hi, Never Never Land, Robinson Crusoe, etc., etc. A few years ago, just for the fun of it, I cut together video clips from the Niku II expedition with scenes from theatrical films as a humorous spoof to show at a team meeting. What struck me was how easy it was. Expeditions to mysterous islands are a Hollywood staple. Perhaps, then, what makes the Earhart Project so captivating (at least, for some of us) is that the story we're uncovering, piece by piece, taps into something very basic in human experience and resonates as a tale we've heard many times before - except this time, it's real. LTM, Ric ========================================================================= Date: Mon, 27 Dec 1999 18:41:25 EST From: Mark Prange Subject: Variation Is the east magnetic variation being applied correctly? 157 degrees True minus 9 degrees of variation gives a heading of 148 degrees Magnetic. But even so, adjusting for variation doesn't change the direction the plane is aimed. If the navigator was unable to sight the sun once on the LOP, and flew 157 True along the advanced sunrise LOP then the Sun would slowly get behind the wing. That would be the case with the LOP stationary, as with an advanced sunrise LOP and no new sun shots. But if he could sight the sun, then his LOP would slowly move just as the Sun's azmuth moves. Counterclockwise. Rotating slowly about Howland. The LOP and the Sun's azimuth would be perpendicular, and the sun wouldn't in that case shift behind the wing. Also, to be technically correct, the LOP would be called "156/336," "155/335," "154/334," etc. as the azimuth changed. But this exact change in the alignment of the LOP is scarcely noticeable. Around sunrise the azimuth change is so slow that the LOP might be called the "157/337 line" for a while even after it was really a 155/335 line. When referring to the "LOP" I have usually had the second case in mind, with the Sun always perpendicular to the LOP, and with Noonan able to make course corrections based on sun heights; although Earhart still called it the "157/337 line" after it would have changed a little from that alignment, the difference is small. A few degrees of error in plotting the alignment of an LOP wouldn't keep that LOP from crossing right over Howland. Mark ************************************************************************** From Ric I think I screwed up my explanation to Ross Devitt about correcting for variation (sorry Ross). I got the conversion backward. To convert True to Magnetic you SUBTRACT Easterly variation and ADD Westerly variation. So - yes - a True heading of 157 degrees would be a Magnetic heading of 148 degrees. I can't agree with you, Mark, about Noonan using a series of LOPs and AE calling them all the same name. It doesn't make any sense to me as a navigational technique and it's not what Weems recommends. The technique is to shoot one LOP then advance it by DR through the destination. LTM, Ric ========================================================================= Date: Mon, 27 Dec 1999 18:44:49 EST From: Birch Matthews Subject: Range of Earhart's Electra Some time ago you asked me if I thought Amelia's Electra had sufficient range to reach Gardner Island. At the time I had not looked at that possibility and wasn't sure; however, I thought it might be possible. Since that time I have done a much more systematic engineering study of both engine fuel consumption, and aircraft performance for each element of her flight. Based upon my calculations, there was insufficient fuel to reach Gardner Island. At best, the airplane had a theoretical endurance of about 22 hours corresponding to a range of approximately 2,800 miles. To reach Gardner, she would have needed an endurance of around 24 hours and a range somewhere around 3,000 miles. My work assumes the following: 1) Amelia was indeed bound for Howland Island. 2) Fred Noonan was a skilled navigator and insofar as possible, pursued a great circle route. 3) Amelia followed the recommendations of both Kelly Johnson and the Pratt & Whitney S3H1 engine operating manual with respect to engine power settings. 4) Amelia's airmanship was excellent and she used good fuel management techniques. *************************************************************************** From Ric What assumptions did you make about total fuel load, route of flight, and winds encountered enroute? ========================================================================= Date: Mon, 27 Dec 1999 19:11:05 EST From: Randy Jacobson Subject: Re: Mystic Musings Once you've figured out Myst, you can graduate to Riven, a 5-CD follow-on which has 5 islands and about 5 times as many puzzles to figure out!

For weeks while I played it, Myst scenes appeared regularly in that state of consciousness between waking and sleep, solutions just slightly out of reach. Sound familiar? Infectious, fun, compelling, frustrating, and a delightful toy. It is also, as you point out, an excellent training device for the scientific method and having gone through both games, I'll go one step further. It's also, with hindsight, a tribute to simplicity. Or maybe things just look simple once we figure them out. I kept notes on and tried to decipher or at least assign meaning to those darn hieroglyphics for the longest time.

One component of mystery (film, literature, etc.) is Suspension of Disbelief*. If the story is presented well enough, we can suspend our disbelief in the story and enjoy it more. An aspect that helps is Limited Scope* or, in this case, Limited Geographical Scope*. The wilder the subject, the easier it is to believe in it if it's far away in a small location with limited access. This "explains" why it's a mystery and why you haven't heard of it in your every day life. For a fairly recent example, this was used to good effect in the beginning of Hunt for Red October. ---------------- * "Suspension of Disbelief" is the actual term normally used in the field. The other two, I can't recall the normal terms used, but they're something like that. ************************************************************************** From Ric Of course, the "willing suspension of disbelief" is a prerequisite for the enjoyment of any theatrical presentation. The interesting thing about the Nikumaroro mystery is that no such suspension is required. It's a classic case of life imitating art. ************************************************************************* From Alan Caldwell Ric, the important thing I got out of your note was that I'm not the only adult playing computer games. Actually I BUY computer games. I have yet to do much in the way of playing. I DO have Myst so you have peaked my interest in it. Do you have "Around the world?" I HAVE played one game which my son brought over and you are right it DOES require some heavy duty logic and good reasoning to play these things. Good experience for the job at hand. My legal training and experience has certainly taught me a lot about putting together a good argument. Probably the most important lesson that also applies here is to be so very careful about misstatements and repeating anecdotal bits and pieces as facts. It is not so important that someone does that as it is that others pick them up and they take on lives of their own. A good solid case is built on tiny scraps of supportable evidence until they begin to eliminate other possibilities. Eventually one is left with an almost inescapable conclusion. It is also good practice to game out possibilities in the hopes that some will obviously be eliminated. The worry is that we have to watch out for false rabbit trails and not get too carried away with irrelevant issues -- except for fun of course.

Our World Aeronautical Charts all show True North, and every day I have to convert 8 deg East Variation to Magnetic Heading by Subtracting the Variation East. I have even gone over old flight plans. Every one shows the same thing. However it really makes no difference to where AE would have finished up, but if she was flying 157 deg TRUE she was flying a compass heading of 148 Magnetic... On the other hand, if the line AE reported flying along was Magnetic (which we have already decided is unlikely) in which case she was flying 166 deg True, and Bruce's engine was found on another Island...

He goes on (Bear in mind that Sir Ian doesn't know much about what we've already learned): "I presume that you are aware of Bruce Brown's biography of Harold Gatty.

In it there is mention of Amelia Earhart's ill-fated journey with the 'boozy ex-ship's navigator named Fred Noonan'. To have made such an uncomplimentary comment I fancy that Bruce Brown must have had some papers regarding Amelia's flight with Fred, especially concerning the construction of an airfield on Howland Island, some 200 miles north of Gardner (Nikumaroro). The U.S. Department of the Interior and the State Department in Washington were heavily involved with questions of sovereignty in the Central Pacific Islands surrounding the Equator at that time, and there is reference in the Gatty biography to that. Having had an airfield constructed to accommodate Amelia's aircraft, there must surely be available to you from the departmental archives some reference to they outcome of the ill-fated flight and, perhaps, mention of the sextant and bones.

LTM (who never goes out into the fog) Roger Kelley, #2112 ========================================================================= Date: Tue, 28 Dec 1999 11:00:06 EST From: Birch Matthews Subject: Fuel Consumption Assumptions With respect to assumptions in my analysis, I selected a volumetric fuel capacity of 1,100 gallons, and a fuel weight density of 5.756 lb/gal at a bulk temperature of 80 degrees F. The weight density number is derived from Pratt & Whitney data. A useable fuel fraction of 96 percent was chosen. In other words, a 4 percent loss due to evaporation, overboard venting, leakage, tank ullage volumes (due to the 3-point attitude of the airplane), and residual fuel in the feed system that cannot be pumped to the engines. In context with the latter, I was guided by a technical report from Bell Aircraft Corporation wherein a useable fuel fraction of 96.9 percent was measured on a P-39 (internal and external tanks). The increased complexity of the Electra fuel feed system warrants a slightly larger number. Eight route scenarios were examined. Interestingly, the total mileage from Lae to Howland varies only a little bit depending upon what intermediate points along the route are selected. In any event, this analysis suggests that Amelia flew around 2,585 miles in 20.2 hours (her last radio transmission) at an average ground speed of 128 mph. My analyses demonstrate that in theory Amelia should have had something like 442 pounds of fuel remaining after 20.2 hours. Similarly, her burn rate at 1,000 feet was about 247 pounds per hour (mixture ratio = 0.07, MAP = 24 in-Hg, rpm = 1,600). This gives a remaining endurance of around 1.8 hours, not enough to reach Gardner. I believe Gardner Island is about 400+ miles south of Howland. At a ground speed of 128 mph, it would take a little over 3 hours to reach this destination. Winds aloft were not considered because the analysis was based on total time and total distance. This yields average ground speed. ************************************************************************* From Ric I agree with you on many points. I agree with you that we have to assume that: 1. Howland was the intended destination (no spy flight detours). 2. Earhart flew the airplane competently according to Kelly Johnson's recommendations. 3. Noonan performed his navigational tasks competently and did the best job possible given the failure of an essential piece of technology (the radio/DF). 4. We agree that the intended fuel load was 1,100 U.S. gallons. 5. I think we agree that route of flight and headwinds are fundamentally unknowable and don't really matter anyway. We know where they started from and when they took off. We can reasonably assume that they reached the vicinity of Howland and we know when they got there. What happened in between doesn't matter as long as the airplane was flown according to Johnson's recommendations. (This is where we differ from Elgen Long's assertion that Earhart departed from Johnson's powers settings.) I question 3 assumptions you have made. 1. Your estimated 4 percent unusable fuel (44 gallons) is based upon one example drawn from a single engined fighter and arbitrarily increased from that figure. I don't know, and you don't know, how much of Earhart's 1,100 gallons was unusable - but we do know that NR16020 was set up specifically as a long-range, record-setting aircraft. We also know that the fuel system schematic shows a "stripping valve" and a "strip wobble pump" in addition to a "hand fuel pump." This certainly gives the impression that considerable attention was paid to making sure that the aircraft didn't carry around any more unusable fuel than was absolutely necessary. While it is true that some fuel may have been lost thorough evaporation and venting between the time the aircraft was fueled on July 1st and the takeoff more than 24 hours later, it is also true that the tanks may have been topped off prior to departure. (Remember, one of our assumptions is that Earhart and Noonan are competent.) In short, I think your 4 percent unusable fuel assumption is pretty shaky, and those 44 gallons represent about an hour of flying time. 2. I'm a bit puzzled by your assumption that the "Amelia flew around 2,585 miles in 20.2 hours (her last radio transmission) at an average ground speed of 128 mph." It seems quite clear from the 19:12 GMT transmission ("We must be on you but cannot see you...) that the crew believed that they had reached the immediate vicinity of Howland Island and had looked around enough to convince themselves that it wasn't right there. The transmission comes very close to Earhart's scheduled quarter-past the hour transmission time so it seems reasonable to presume that they reached what they thought was Howland's position sometime right around 19:00 GMT. Everyone seems to be in agreement that Noonan was attempting to find Howland by the only means available to him, that is, advancing the sunrise LOP - and everyone seems to agree that he should have been able to do that with some degree of accuracy in an east/west sense, but not in a north/south sense. In other words, it seems most reasonable to assume that at about 19 hours into the flight the aircraft was on a 157/337 LOP running through (or near) Howland Island but was either to far north or too far south to see the island. This is the time that represents the end of the enroute portion of the flight, not the final transmission heard an hour later. From 19:12 on they're searching for Howland, or any place to land. The 157/337 LOP running through Howland is roughly 2,550 statute miles from Lae (a little less if north of Howland, a little more is south). An airplane covering that distance in 19 hours has made an average groundspeed of 134 mph. For Earhart, cruising at the recommended 150 mph, that would mean an average headwind component of about 16 mph for the entire trip - not at all remarkable. 3. I don't understand how you conclude that, at the time of the last transmission heard by Itasca at 20.2 hours, the aircraft is 400+ miles from Gardner. If the aircraft was directly overhead Howland at that time it would be 410 statute (356 nautical) miles from Gardner, but that's the one place we know it wasn't. What we do know is that, for the past hour, the airplane had been searching for Howland and, when last heard from at 20:13 was "running on the line." Because the rational direction to search farthest on the line is to the southeast, and because the flight did not reach Howland, it seems most likley that the aircraft was south of Howland and perhaps quite a bit closer to Gardner than you theorize. I respectfully submit that the endurance calculations need more work before anyone can conclude that the aircraft could not have reached Gardner.

We weren't too sure for a while. In the first days we were all very worried, but we just had to wait and see. They sent out lots of search parties and we were all hoping, but we just had to wait. We know that she was close to Howland Island because of the radio calls to the Itasca. There were clouds to the northwest, which is the direction she'd be coming from. The water was reported to be smooth and glassy that day. She was flying into the sun, so maybe she got too low and went in. I knew a fellow that was taking a CW class, and in walked Amelia. She only stayed for two classes. So she didn't know it, and Noonan didn't know it. She had the brand new radios so she could talk, but she couldn't make out what they were sending back [in Morse code]. ************************************************************************* From Ric Of course, the flight would not be coming from the northwest, the scattered clouds were only slightly less scattered in that direction, and the sea was not glassy smooth. ========================================================================= Date: Tue, 28 Dec 1999 14:53:46 EST From: Ross Devitt Subject: Range of Earhart's Electra Birch, This really interests me as I've worked the figures available backwards and forwards and can't come up with anywhere over 18 hours for an arrival time and 3 hrs remainng fuel. I've been looking at all the suggested distances for weeks and the estimates of distance from Lae to Howland vary tremendously. The most frequently quoted seems to be "over 2500 miles". I have checked with software, and various other references and the only way I can get anywhere near that is by using Statute Miles. I've just been over the figures again (this time with my trusty computer) and I still get the Great Circle Bearing as 079 deg and the Great Circle Distance to be 2263 Nautical Miles. (close to 2600 Statute miles). I even went whole degrees in opposite directions to factor in some extra distance. (the real figure comes up around 2240+) Early in the flight AE reported "wind 23kts". The only wind a pilot is interested in reporting is either a Headwind (which if she was sitting on a planned 150kts would drop her back to around 125 ground speed) or a tailwind (which would see her speeding along at around 175 kts (200Mph). So, assuming a 25kt headwind for the whole flight, and using Statute Miles (2600 from Lae to Howland (Great Circle), we have to convert knots to miles per hour (125kts = 144mph). 2600/144 = 18 hrs Lae - Howland. (checking... 2265nm/125kts = 18hrs) it works. 52Gph (worst KJ figures all the way) x 18 hrs = 936gallons. 1100gallons - 936gallons = 164gallons remining near Howland 164gallons/52gallons_hr = 3.1hrs. Leaned out 164/40 = 4hrs. All at the worst figures from the Kelly Johnson telegrams.. If AE was able to fly at 10,000 at full throttle for the last 9 hours as recommended she was expected to use 100 gallons less fuel. What am I not seeing? (This is a serious question - I'd like to know what I missed.. and why it doesn't work). RossD *************************************************************************** From Ric I would like to suggest that we all throttle back for a minute. The question of the airplane's probable endurance is, of course, central to any hypothesis regarding its fate. Our earlier calculations, based upon a 1,100 gallon fuel load and Kelly Johnson's recommendations, gave us an estimated maximum endurance of around 24 hours and 10 minutes. Others, including Elgen Long and now Birch Matthews, have offered dissenting viewpoints. We had contemplated commissioning a "blue ribbon panel" of experts to look at the problem but I'm beginning to think that this question mught be best addressed, step by step, right here on the forum. For one thing, if a panel of experts did come up with an answer we would demand to see their work anyway. Step 1 The first thing we all need to agree on is the methodology - i.e. how are we gong to calculate the aircraft's endurance? Step 2 Next, we'll need to decide what information we need to have in order to carry out those caluculations. Step 3 Then we'll need to see how much of that information we have and what, if any, we still need to get. Step 4 Some information we wish we had is simply not available, so we need to identify what we don't know and decide what assumptions are reasonable to make. (This could be the tricky part.) Step 5 Finally, once we know what information we need, what information we have, and what assumptions we're going to make, we'll be able to run the numbers and see where we come out. I don't think that it's reasonable to expect that we're going to end up with a single hard number but we should be able to establish a best case/worst case spread that represents a reasonable assessment of the available evidence. Before we start: Is there anyone out there who thinks that this is a dumb way to approach this issue or sees a need to modify the steps outlined above? ========================================================================= Date: Tue, 28 Dec 1999 14:54:53 EST From: Ross Devitt Subject: Re: Virtual Reenactment / Mystic Musings....

I'd like to comment that although these instruments may be "old fashioned", they are functionally virtually identical in concept to modern sextants, and certainly were in no way out-of-date in the 1930's. The only major design change in fine sextants in the last century has been the incorporation of the drum micrometer for fine adjustment, replacing the previous microscope scale reader. My sextant has the drum micrometer, as presumably did Noonan's. It would have been entirely logical for Noonan to carry a marine sextant as a backup to his aviation sextant. The principal difference between the former and the latter is that the latter incorporated a spirit level, which relieved the navigator from the need to have a clear sight of the horizon, which would be a problem for an aircraft flying above clouds. In clear weather, either device would serve the navigator's purpose. (With either instrument, the navigator would need to have an accurate estimate of his altitute above sea level.)

I appreciate your perspective because it made me think and reconsider what I have done thus far. Following are my thoughts to your items 1 and 2, the 4 percent fuel fraction that could not be used, and the 2,585 mile assumption. As to your comments in item 3, last radio transmission and assumed position, let me defer responding at the moment. You made me rethink this situation. 1) I agree that the useable fuel fraction value I chose is open to debate. However, I stated my estimate and the basis for this number. If anyone has a more realistic number I am more than ready to reconsider. Of one thing I am certain. The useable fuel fraction was not 100 percent. For instance, in all probability some or all of the tanks had small ullage volumes. Typically this is a design consideration to allow for some fuel expansion due to heating. Tank ullage on Amelia's airplane could also occur simply due to the aircraft three-point attitude with respect to the tank filler port position. If this caused some ullage volume, topping off the tanks on the day of departure would not changed this condition. From a more general perspective, I applied the "useable fuel fraction" concept to account for various uncertainties that come into play to one degree or another. This is a common engineering approach in many if not most analyses. You also mention the modification to the fuel tank feed system made in the spring of 1937. Someone, quite possibly Kelly Johnson, recognized that not all of the fuel could be drained from the all of the tanks. In fact, the residual amount was probably appreciable and something had to be done. The engine-operated fuel pump could not provide sufficient suction to maximize fuel removal from the greatly expanded fuel system. This resulted in the addition of a "stripping valve" and "strip wobble pump." The stripping valve is simply a two-position control device integrating the additional wobble pump into the existing fuel feed system. The strip wobble pump acts as a hand-operated booster pump. It no doubt improved the situation, but would not have achieved the 100 percent goal. I am probably preaching to you about things with which you are already quite familiar. If so, please forgive me. 2) Your comments about my assumption that "Amelia flew around 2,585 miles" (to Howland) in 20.2 hours is well taken. I tend to agree that this understates her average ground speed based upon her radio transmission of 19:12 GMT. I do not think a distance of 2,250 miles is the appropriate measure, however. Earhart and Noonan did not fly a great circle route towards Howland, not exactly at least. They deviated slightly to the south early in the flight. Depending upon which track one prefers (after the initial position fix report to Lae, some mileage was added to the nominal great circle route. I considered eight navigation scenarios (one each of which included a 30 nautical mile offset - one to the north and one to the south of Howland). The mileage spread between the minimum and maximum distance for the eight scenarios was 71 miles. Because they were searching for Howland at the old coordinates, I used a great circle distance of about 2,550 (statute) miles. I took the midpoint of the 71 mile variance and added it to the 2,550 figure. Rounding this to a whole number gives 2,585 miles. If Amelia was in close proximity to Howland at 19:12 GMT, you are correct and her average ground speed would have been around 135 mph. (This is a long winded way of saying you have changed my mind.) Regarding your item 3, last transmission and possible location of the aircraft at that time, I wish to do some more thinking. Your comments stimulated me to review my conclusion. More later. ************************************************************************** From Ric Earhart's initial position report, heard at 15:18 Lae time (05:18 GMT) as recorded in the Chater letter, is a problem. Taken at face value, it doesn't make any sense so everyone has to change it in some way. If you accept the postion reported - 150.7 East, 7.3 south (only about 186 nm from Lae) - you have to not only assume that they made a huge dogleg in their Great Circle route for some unexplained reason, but you also have to assume that the position reported is several hours old and actually predates the report heard an hour earlier at 14:18 (04:18 GMT). The alternative is to accept that the aircraft made an average groundspeed of under 50 knots. I find it much easier to accept that the coordinates were either heard wrong or transcribed incorrectly somewhere along the way and that the airplane was, in fact, proceeding along the Great Circle at a "normal" pace. Like the great "circling" debate, there's no way to know for sure what actually happened and I don't have any trouble with your assumption that 2, 585 is a good compromise to use as the distance traveled up to the point that they started searching for Howland and it sounds like we're in agreement that that point in the flight came at sometime just prior to 19:12 GMT. We're therefore in agreement that the plane's average groundspeed during the enroute portion of the flight seems to have been in the neighborhood of 135 mph. That's progress. How, I wonder, can we get a handle on what kind of "stripping" efficiency was possible in Earhart's fuel system? I certainly agree that 100 percent is unobtainable but I can't help but feel that your 4 percent is a bit stiff. She had 12 tanks in the airplane. If a gallon of fuel in each tank was unusable that's 12 gallons or about 1 percent of the 1,100 gallon load. Is that within reason for a fuel system with a stripping provision? Or is that hopelessly optimistic? Somebody knows this stuff.

As to methodology, I suggest that there are three components to the analysis: 1) Basic to the process is an approximation of Amelia's flight profile. This can be constructed using the radio transmissions and the known starting time of 10:00 local. It has to be rough at first until elemental times calculated from steps two and three below can be added to adjust the first approximation. 2) It is necessary to calculate aircraft performance. (Any standard aeronautical engineering text will describe the necessary steps and equations.) Of particular interest is time-to-climb and descend. I would suggest a starting gross weight at Lae of between 15,000 and 15,400 pounds. You will have to calculate a zero lift drag coefficient. Use the method presented in Quest for Power (NASA). Assume a range of lift coefficients and calculate the corresponding drag coefficients. From these data you can construct a drag polar diagram. Consider doing this for various flight conditions. You will need this in subsequent aircraft performance calculations. 3) It is necessary to calculate fuel consumption for various power settings at various altitudes from sea level to 12,000 feet. The first calculation to make is with the S3H1 operating at 5,000 feet, full throttle. You can get a handle on a couple of variables because you are dealing with a known condition and known results. Kelly Johnson's data gives you four additional known data points or results. You start by determining RAM air pressure (suggest 132 mph to start) and the stagnation temperature at the carburetor face; account for a pressure drop across the carburetor, mixture cooling due to fuel evaporation; compression heat addition to the mixture due to supercharging; supercharger recovery pressure; and, heat addition to the mixture in the manifold pipes to the cylinders. Manifold pressures, engine speeds and mixture ratios are known quantities. Iterate assumed values of supercharger pressure recovery and heat added to the mixture in the pipes until the correct answer is obtained for the known conditions mentioned above. Plot engine rpm vs supercharger pressure recovery and vs temperature additions in the pipes for the known conditions. Curve fit the data points. This allows you to select values for these two parameters for other power settings for which you do not have known data. Refine the end results by using a local atmospheric temperature at sea level and applying a temperature lapse rate to obtain upper air temperatures. Substitute these values in your fuel consumption calculation spread sheet to get a bit closer to what happened on July 2 and 3, 1937. One of the solutions needed is the rate and total amount of fuel expended during climb operations. Although Kelly specifies a power setting for climb, he does not indicate an estimate fuel consumption rate. Nor does he provide fuel burn rates for engine warm up and takeoff. These have to be calculated once the basic program is set up. Thank goodness for the computer! ************************************************************************** From Ric What a relief!

TIGHAR is not about flying. TIGHAR is about aviation historical investigation and preservation. Anybody can learn to fly (heck, I did). Learning to think is a lot tougher (I'm still working on it). The only winds aloft information we have for Howland comes from Richard Black's observations (Black was the Dept. of the Interior representative) at local noon. Cloud cover was five tenths cumulus Surface wind was ESE at 16 (but he doesn't specify kts or mph) 1,000 feet ESE at 15 2,000 feet E at 17 Cloud bases were at 2,650 feet so he couldn't track the balloon any higher than that. The Itasca deck log records only surface wind. Throughout the morning the wind is out of the East at force "2" (1 or 2 knots) except for the 10 o'clock observation where the wind is ESE, and the 7 and 8 o'clock observations record a wind speed of "1" (defined as "light air"). The noon observations shows no significant difference between surface wind and winds at 1 or 2 thousand feet. If that also held true for the early morning hours it certainly looks like wind was not a factor in the last few hours of the flight. LTM, Ric ========================================================================= Date: Wed, 29 Dec 1999 10:07:56 EST From: Ross Devitt Subject: Re: Electra Endurance Just a note. Now My experience as a pilot is limited, but it is current. Looking at the ACMs for several aircraft here there is a definite trend. Allowance each tank HAS an unuseable fuel quantity. It IS specified. It is NOT taken into account as a part of the fuel load either for flight planning or for Reserves. I agree with Birch that an allowance would have to be made for some volumetric expansion, and would like to know how it is worked out. Our visible fuel losses to evaporation here (at 80deg + shade temps and who knows what in the sun, with the aircraft standing in the sun all day) seem negligible (looks like somewhere in the order of 1% per 4 days in the sun If That - in reality you can't see the difference.) I'd suggest, that very close to 1100gals "by volume" actually did start the trip. My question? does the weight of the fuel change with temperature, or is the weight constant through the change of volume. (yes I did science - I just want to see someone else's answer..) Also, I am prepared to do some actual "tank dipping" on an aircraft sitting in the same tropical conditions as in my parachute postings. It is not being used very often at present and sits a week or more at a time in the tropical sun with vented tanks. I'm sure I can get some pretty accurate evaporation figures. Bearing in mind that the greater the volume of fuel, and the fuller the tanks, the lower the evaporation rate. Also at a 10,000ft cruising altitude, evaporation would be considerably lower than ground level. RossD *************************************************************************** From Ric The density of the fuel will change with temperature and so warm fuel will take up more volume than cold fuel. Because the airplane only sat for one day between the time it was fueled and the time it departed Lae, I can't imagine that evaporation played any significant role. It has been alleged that, because the airplane was fueled in the morning and sat around all day, expansion would cause overflow through the vents which could amount to a loss of as much as 8 gallons. But to suppose that such a loss, if it occurred, was not replaced prior to take off would seem to imply a level of ignorance, inexperience, or incompetence on the part of the crew that is unjustfied. In short, I agree with you. I think the airplane went out of Lae with 1,100 U.S. gallons of fuel aboard.

This species also appears to be rather delicate in captivity. In a paper on the subject, Robertson (1991) gives some recommendations on husbandry and points out many of the problems known for this animal. This animal comes from the Indo-Pacific tropics and parts of the Japanese Ryu Kyu islands. It ranges from the Aldabras to the Solomon Islands, Guam, and Fiji. It is threatened by invasive animals, by humans as a food and medicinal source, and habitat destruction. Husbandry: This species should probably be kept singly, as aggressiveness has been reported. A permanently moist sand substrate and a half clay pot (used as a hideaway) are recommended. The crabs will burrow into the sand. A large bowl of fresh water is necessary. High humidity is recommended. (These are not salt-water animals.) Robertson reported using an 11 hour light/13 hour dark schedule, with a 27-29°C daytime temp and 23-26°C nighttime temp. Feeding: These crabs are omnivorous, and Robertson reported the acceptance of coconuts, dead mice, fruits, fish, and small crabs. Cuttlebone was provided as a calcium supplement. Problems: Mites were cleaned off with a water sprayer to remove any chance of damaging the crab's respiratory system. Stress appears to be a big problem with these invertebrates, and much care should be taken to keep traffic low around their cages. Bacteria (Vibrio) is a known pathogen. Moulting can also be difficult for these animals. Citation: Robertson, M. 1991. Husbandry and moulting behavior of the Robber or Coconut crab Birgus latro at London Zoo.

It appears the foregone conclusion of going back to square one is that the best the exercise can do is to produce yet another estimated range with yet another plus/minus factor. Whether that plus/minus factor is 100 miles or 400 miles seems to be a moot issue. Either she made it or she didn't. TIGHAR has already established an estimated range with a plus/minus factor and hypothesized that she made it. Does it really matter if that plus/minus factor is larger or smaller than TIGHAR's earlier estimate? The only value I see of going back to square one is to establish that the Electra indeed COULD NOT reach Niku.

LTM, Ric ========================================================================= Date: Wed, 29 Dec 1999 14:47:22 EST From: Birch Matthews Subject: Fuel Estimate at 19:12 GMT I have taken another look at my figures, this time from the perspective that at 19:12 GMT, Amelia was in proximity to Howland Island. (It seems pretty clear from her radio message that she thought she should be very near Howland.) Using my methodology, I calculate that Amelia should have had around 740 pounds of (useable) fuel remaining. Similarly, she was burning fuel at the rate of 247 lb/hr assuming she remained at 1,000 feet. At an average ground speed of 135 mph, she could have flown a distance of 405 miles or 3 additional hours from that point onward. This says that if she was within 405 miles of Gardner, she could indeed have reached the island. (I am using statute miles unless otherwise noted.) On this basis, I retract my earlier conclusion that it would have been impossible for Amelia to have landed on Gardner. I am glad you made me go back and take a second look. Whether it is probable that Amelia reached Gardner is another question. It seems, however, that it is feasible. Another perspective is also intriguing. If her average ground speed was approximately 135 mph, it could mean she overshot Howland (135 mi/hr x 19.2 hr = 2,592 miles). And finally, I come back to the 19:12 GMT message which also indicated . . ."but gas is running low." My methodology may understate her fuel consumption. Certainly there is a +/- tolerance associated with my calculations as with any engineering estimate. I can think of more than one reason fuel consumption may have been greater. Problems with one or both Cambridge Fuel Analyzers or inadequate carburetor heat would be significant reasons. Running leaner mixture ratios would have shown up in the cylinder head temperatures even if the Analyzers were biased or malfunctioning. Even small temperature variations in the charge mixture make a dramatic difference in fuel consumption. ************************************************************************* From Ric I agree. Many scenarios would result in less than optimum endurance and few would net in better results (like maybe an unexpected encounter with a KC135). Still, historical investigation - like politics - is the art of the possible, and with so many independent factors pointing toward something wierd going on at Gardner Island, a realistic assessment of the fuel situation which makes the arrival of NR16020 a possiblity is interesting, to say the least. We'll go ahead with our own reassessment of the aircraft's endurance. It'll be interesting to see how closely our figures match yours.

If the plane was south of Howland (let's assume 50 to 100 miles, just to see how the 'numbers' work out) at 19 hours into the flight, the Itasca could have been hearing Earhart's radio transmissions via ground wave. If, over the next 1.2 hours, Earhart flew 'on the line' south, towards Gardner (figuring an average ground speed of about 130 mph), then this would have placed her 200 to 250 miles from Howland at the time that her last radio transmission was heard. I think 'skip conditions' that time of morning, on 3105 khz., might be just about right for very good signal propagation over a 200 to 300 mile path. This would also have placed Earhart within about 160 to 210 miles of Gardner, which at 130 mph, would have placed her at Gardner in about another 1.23 to 1.6 hours, after her last transmission was heard. (By the way, skip conditions, using frequencies in the 6000 khz range, might not likely work for a path of only 200 to 300 miles, during that time of morning). Interestingly, considering my 'assumptions' above, and even using the "remaining endurance" time of 1.8 hours that Birch came up with, this would still allow time for Earhart to have reached Gardner, and maybe still have enough fuel left, after landing, to run the starboard engine (I think that was the one?) enough to keep the batteries charged for the radio to work over the next couple of days.

I have a suggestion - given the uncertainties in the inputs, it might be wise try to define a range of values (rather than a single value) for the flight endurance. Since all the values which make up the analysis are estimates, I think that it is appropriate to estimate the error of these estimates, and report this as well. The end result would be a best estimate +/- an error estimate. There are at least two (maybe more) ways to do this - either do a sensitivity type of analysis, ie, a reasonable "optimistic" and "pessimistic" analysis in addition to the "best estimate", or use a Monte Carlo analysis with appropriate error distributions on the input variables to generate a cumulative probability curve. In either case, a lot can be gleaned from even the simpler of the two analyses. For example, there is a big difference in an estimated range of xxxx +/- 10NM and xxxx +/- 200NM. Even better is the shape of the cumulative probability curve from a Monte Carlo analysis. Either process can also identify the sensitive inputs - those which deserve the most care and effort in estimation. Regards, Tom MM ************************************************************************** From Ric I agree that it's important that, whatever numbers we end up using, we make it clear how confident we are that those numbers are correct. For example, the distance between geographical features probably hasn't changed much since 1937 (plate tectonics aside), so those will be pretty hard numbers. Other numbers will be a bit softer and some will be downright mushy. So - yes - that all needs to be stated up front. Let's also keep in mind that the point of this exercise is not to determine what happened (or even probably happened) to Amelia Earhart. All we're trying to do is establish is whether the aircraft "should have" had enough endurance to reach Gardner Island. I don't know enough about Monte Carlo simulations to know whether that's a good way to approach this question.

How would anyone plan a flight accurately if the number of USABLE gallons was not known?

First, why is unusable fuel a percentage of the fuel loaded? If you start with tanks half full or completely full the usable fuel (that fuel which can not be transported to the engines due to the fuel system design) is the same in either case. Second, 44 gal. seems like a lot of unusable fuel for any relatively light two engine airplane. That is 90% of a 50 gal. drum. I would think 10 gal or possibly 20 gal would be much closer. My two tank Cessna has only 4 gal that are unusable, This needs to be checked and compared to similar aircraft or any L-10s that may be available. I would have thought the unusable fuel figure would be in the manufacturer's literature. Dick Pingrey 908C ************************************************************************** From Ric Unfortunately, I can't find any mention of usable/unusable fuel in the Lockheed literature we have, and besides, that would be for the standard airplane rather than the "special" with the elaborate long-range tank system. ************************************************************************* From Christian Hello!

Ie like the total quantity of gas needed for the INITIAL fill of the DRY brand new tanks out of the factory? Or is it the actual volume needed to RE fill the tanks after subsequent uses? Aren't aircraft actually tested for volume, until they "run dry", until they suck fumes? Wouldn't that be where the 1100 figure comes from? Even if this was not actually tested formally at the factory, AE/FN "should" have run their tanks dry, a few on each of their numerous previous flights. And on careful refilling the next time they would have learned the ACTUAL PRACTICAL volume of ea tank... Or is it impossible to run an aircraft tank dry, even if one has another half dozen full tanks left?

By the way, who are those two dead frenchmen you are serching for Ric? ************************************************************************** From Ric Charles Nungesser and Francois Coli attempted to fly nonstop from Paris to New York on May 8, 1927. Had they arrived (as everyone expected) Charles Lindbergh would not have made the trip in the opposite direction twelve days later - and the world would be a rather different place. Imagine an American aviation industry without the inspiration of Lindbergh's flight. Nungesser and Coli vanished, in Lindbergh's words, "like midnight ghosts." Their disappearance was a hingepin in aviation history and their aircraft, l'Oiseau Blanc (the White Bird), is history's most important missing airplane.

On the other hand, water is very scarce, and cuts become infected rapidly, so both dehydration and death from an infected cut (easy to get on the coral, sharp sticks, broken up airplanes,etc.) are dangers. It would certainly be possible for people at one end of the island not to know that a bunch of other people had arrived on the opposite end, particularly if one were sick, injured, or otherwise not very mobile. On the other hand, it's a bit harder to imagine live people being missed by the British/Gilbertese team that walked clear around the island only a few months after Earhart's disappearance. Not impossible, but it seems unlikely. LTM Tom King ************************************************************************** From Ric The walk around the island was made by Eric Bevington and a handful of Gilbertese. Eric's diary, and his oral account of the journey as related to me in 1991, make it quite clear that what started out as an exploratory hike turned into an "adventure", the sole purpose of which was to make it back to camp alive. The island was far larger than they thought it was and, incredibly, they had brought along no drinking water. *************************************************************************** From Ross Devitt >Is it >possible that two people could be on the island and not know that a ship had >arrived and that over twenty people were ashore? Absolutely. Ric has obviously spent a little time on a deserted tropical island and found out it is not necessarily "Bali Ha'i". You could be at one end of the island the size of Niku and have a group of people at the other and if you were weak or holed up somewhere you'd never know. The problem with tropical islands is that they only get rain for a short period each year and unless there is a well or fresh water catchment you have to be fit enough to (and know how to) climb coconut trees for water (milk) the rest of the year. That is assuming your island supports coconut trees. There are other ways of obtaining fresh water, but.....? RossD ************************************************************************** From Ric In 1937 there were, reportedly, 111 coconut tree in bearing on the island.

We'd like to know (a) whether crabs actually scatter bones at all (If they don't, then the bones must have been scattered by something else -- e.g. dogs brought with the colonists, which would give us a handle on when they were scattered; and (b) if they do scatter bones, how far they scatter them (horizontally and vertically); and (c) is there any sort of pattern to the scattering? Unfortunately, for some strange reason nobody seems to have given these fascinating questions a whole lot of research attention. Re: Crabzilla And then there's the song called "The Crab of Aukaraime," which is not fit for family consumption (as it were). Re: the crab website That's a pretty wonderful web site.

The latter scenario, which would be clear evidence that Birgus latro does go off with his dinner, seems unlikely.

LTM, Ric ========================================================================= Date: Thu, 30 Dec 1999 12:56:08 EST From: Robert Klaus Subject: Fuel Venting On the question of possible fuel venting. If 1100 gallons were put in, and the fuel subsequently warmed, expanded, and spilled through the vent system, then there would not be eight gallons less, or any gallons less. There would actually be more gallons of fuel than had been pumped in (but fewer pounds). If there wasn't more volume then it could not spill out. The point of this is that range is not based on how many gallons of fuel were in the aircraft, but how many pounds. The original data is unfortunately based on gallons of fuel rather than pounds. To determine the actual fuel load some estimate of the fuel temperature will have to be made. Robert Klaus *************************************************************************** From Ric Yes, and I suggest that we use 80 degrees F as that temperature, as did Birch Matthews. The aircraft was fueled on the morning of July 1st following the test flight. Presumably that fuel, stored in steel drums, was cool from the night before. During the day the airplane can be expected to have heated up and the fuel expanded, with some unknown amount (poundage) being lost to venting. That night, the airplane cools down again, as does any gas remaining in the drums. On the morning of July 2nd anyone sticking or visually inspecting the tanks should notice that they're down some. In accordance with our assumption that Earhart and Noonan are neither stupid nor negligent, we must also assume that the tanks are topped as part of the preflight preparations. 80 degrees F seems like a conservative temperature for the fuel at the time the flight departs at 10 a.m. local time. LTM, Ric ========================================================================= Date: Thu, 30 Dec 1999 12:59:26 EST From: Ross Devitt Subject: Re: Electra Endurance Plus perhaps a little more than 1100 if you include fuel listed as "unusable". As you are probably aware typically some fuel is designated unusable. I just happen to be typing up a new copy of the handling notes for the Warrior. In section 1 - DESCRIPTION sub section 2. "(ii) The capacity of each tank is 20.8 Imperial Gallons, with .8 gallons in each tank unusable, giving a total usable fuel capacity of 40.0 Imperial Gallons. A visual measuring tab........ ..... (40 Imp Gallons - 181 Litres)." According to my trusty whizz wheel, 0.8 Imp gallon = 3.7 litres. per side x2 = 7.4 litres unuseable. If that fuel could be scavenged with a wobble pump I would have an extra 12 minutes of flying time. The point is, we don't know how much unusable fuel was available to be scavenged in an emergency. Also, this fuel is often contaminated with water (a considerable amount at night in an empty tank on the equator). If they had to try scavenging it could cause problems. One of the last things a pilot does before a long trip is to top up the tanks and check for water. If the Electra had been sitting all the previous day in the sun and the fuel had expanded and vented - surely prior to the fuel contamination check in the morning they would have topped off the tanks. By 10.00am the temperature change would be negligible. By 2pm it was getting very hot, but by then they were well on their way and had space in the tanks for expansion. RossD ************************************************************************** From Ric And long before that they should be up where it's not so hot. ========================================================================= Date: Thu, 30 Dec 1999 13:37:16 EST From: Ross Devitt Subject: Re: Fuel Estimate at 19:12 GMT 135mph still assumes a head wind all night.... and 115kts. Finch's published journal over the same area shows 120 - 125kts or 138 - 144mph (not a lot of difference) which, compared to oither speeds maintained over the route would suggest (1) fuel conservation or (2) prevailing easterlies... RossD ************************************************************************** From Ric Where can we access those journals? ========================================================================= Date: Thu, 30 Dec 1999 13:40:33 EST From: Birch Matthews Subject: Re: Kelly Johnson & Fuel Consumption Alan Caldwell asks if we have any better source on the subject of fuel consumption than Kelly Johnson. That's not the question to ask, for Johnson was an undoubted expert. It's what Kelly didn't leave us in the way of information that is important. Consider or remember that Kelly's data was based upon a standard atmosphere. Amelia did not fly in a standard atmosphere and therefore, these differences have to be taken into account. Fuel consumption will therefore vary slightly over Kelly's findings. Remember also that Amelia flew at one or two different altitudes than planned for by Kelly. Thus you have to view Kelly's recommendations as a general guide as to the flight profile and power settings she should employ. Weather could easily force her to vary from the plan that Kelly envisioned before her first world flight attempt. In addition, Kelly gave Amelia a climb power setting, but that doesn't tell us what the engine consumed during any and all climbing flights. A small amount of fuel was also consumed in engine start and warm up and taxiing. This is why it is necessary to assess the last flight in elemental detail. Others puzzle over my terminology and/or use of "useable fuel fraction." If this is not a term used in the aviation world, I apologize. Some background. Interest in just how much of the fuel loaded onboard an airplane could reach the engine(s) certainly came to the foreground in the U.S. during the early part of World War II. With the destruction of the Army Air Corp fighter aircraft at Pearl Harbor on December 7, 1941, aircraft resupply became paramount. The quickest way to replenish fighters was to fly them across the Pacific. This prompted Bell and Curtiss to study the problem of extra long range operations. Bell made the test I referred to earlier. Curtiss did also, although I don't have their data. Other manufacturers probably did similar work. The same consideration was made with regard to getting fighter aircraft to England as fast as possible. I don't think (but admittedly don't know) that people studied the useable fuel concept prior to World War II. As to tank volumetric capacity, this is often calculated by the tank designer based upon his drawings. I have been through every Lockheed technical report existing in the Lockheed archives that was generated for the Model 10 and Model 12. None addressed verification of tank volume. These tanks, including the special ones made for Earhart, were shaped to conform to the envelope in which they were installed. They may or may not have incorporated an ullage volume. I don't know; however, it not an uncommon practice. One cannot simply attribute trapped residual fuel to the tanks. There were a lot of lines, fittings, valves and controls associated with the Earhart fuel system. I assure you that World War II manufacturers took into account trapped fuel and oil in their systems. You will find this information on many detail weight statements. Trapped fuel on the P-39 amounted to 3.1 percent. Somewhere I have a similar figure for the P-51 (can't lay my hands on it at the moment). Memory tells me it was just slightly greater than the P-39. Hope this helps answer some questions as well as explain some of my thought processes and considerations. ========================================================================= Date: Thu, 30 Dec 1999 13:47:43 EST From: Ross Devitt Subject: batteries >still allow time for Earhart to have reached Gardner, and maybe >still have enough fuel left, after landing, to run the starboard engine >(I think that was the one?) enough to keep the batteries charged for the >radio to work over the next couple of days. > > John Rayfield, Jr. - KR=D8Y Just how many batteries were on the Electra and what were they.

I tied two 6V dry cells toghether and kept the 27Mhz marine set working for two more nights and days for scheds only with another battery change. Dry cells are not as good as accumulators and modern radios don't have valves - but many old valve sets ran off batteries....

NR16020 carried a second, and presumably identical, battery. The opinion that the airplane must be able to operate an engine to recharge the battery(s) was based upon the length of time that the alleged post-loss signals continued. ========================================================================= Date: Thu, 30 Dec 1999 13:51:57 EST From: Ross Devitt Subject: Sideways Off topic - Radio and searching from 200 miles. This is from a flight in 1928. Probably before Amelia thought of her attempt. Kingsford-Smith and Ulm believed their critics wrongly identified their Pacific effort with other attempts that they saw as ill-advised, ill-prepared and therefore ill-fated. For instance, they put the Fokker through a number of testflights with increasing overloads and had the Douglas company strenghten the parts most afflicted. Also, they severely tested their ability at blind flying and radio navigation, both still quite a novelty but essential for their success. To prepare themselves for the long flights, they frequently went out driving for fifteen hours, then flying for four hours, running for two, back to flying and so on for a total of some forty hours. Apart from their fixed radio transmitters, they had a watertight, battery-powered emergency radio, the aerial of which could be lifted with a kite or some gas balloons they carried. First across the Pacific In short, their preparations covered every eventuality. And so with complete confidence in their aircraft, its engines and their own ability Kingsford-Smith, Ulm, Lyon and Warner awaited the right moment. It came on May 31, 1928, with favourable weather predictions for the route to Hawaii and the advantage of a full moon during the night. The take-off from Oakland, close to 9 AM, went well and Kingsford-Smith describes how, flying over the Golden Gate which lay glistening in the morning haze, he felt relieved that after all their preparations they were finally under way. The flight itself was quite uneventful. In fact, to the two pilots who could hardly move and were sitting in the horrendous roar of the engines, it was probably boring more than anything else. Kingsford-Smith, a hopeless addict, continually longed for a cigaret. But the sunset was spectacular and for the first hours of night, the moon lighted their path, and stars filled the sky. At ten, Lyon threw out a flare, to check for drift. At close to midnight, to avoid some rainclouds they climbed to 4,800 feet, but otherwise the weather was as perfect as predicted. Shortly before two, they noticed some lights far below. Kingsford-Smith used his spotlight, fitted with a Morse key, to make contact with the ship and let them know the "Southern Cross" was doing fine. Within an hour, they passed another ship, from which Warner received a radio bearing. They were the only two ships they encountered on their entire Pacific crossing. When dawn finally came, Kingsford-Smith decided to descend below the clouds, as it had become rather chilly in the cockpit. At 8 AM, Lyon estimated Hawaii was just over 200 nautical miles away. A number of times, the land Kingsford-Smith or Ulm spotted turned out to be yet another cloud bank, until finally, close to 11 AM, Mauna Kea came into view. At 12:17 PM, the "Southern Cross" touched down at Honolulu's Wheeler Field, after a flight of more than 1,700 nautical miles. The full text is at: http://home.worldonline.nl/~lbb/smith.htm It is not a direct quote, but I have read the published journals of Ulm and Smithy and it is pretty close especially the descriptions of looking for Hawaii. Notice that looking for a tiny island (Hawaii) from a 200 mile estimate they faced at least as difficult a time as Earhart and Noonan would have faced looking for another tiny island (Howland). Interesting given the similar radio equipment, and that Kingsford Smith's worked - and that he knew morse code... Rossd ************************************************************************ From Ric Compared to Howland or Niku, the Hawaiian Islands are like continents. ========================================================================= Date: Thu, 30 Dec 1999 14:25:55 EST From: Doug Brutlag Subject: Reenactment Flight I've been running some numbers to try figure what would be the best aircraft candidate(s) for the reenactment flight. A question I have is what kind of data would you like to collect if or when this becomes a "go". Right now the field of candidates is slim. Problems are going to be distances involved, range vs payload, airports/alternates available, fuel availability & prices-turbine &avgas, services, etc, etc, etc(from the "King & I"). If data collection is a priority a 767 isn't going to do anything for you I'm afraid. Depending on what kind of data you want-winds, celestial sights, topography on an island flyby, you need a low & slow aircraft-preferably a turboprop although a 4 engine recip would be ok. You could still use the jet to sell seats on and possibly make some coin to finance the next expedition. The jet could then rendevous with a smaller data collection ship. Right now I favor a DC-4/C-54, turbine powered DC-3, or possibly a DHC-7 with long range tanks & higher gross weight mod. I am most familiar with the Dash 7 as I have a type rating and 1000 hours in it. Outstanding machine w/STOL capability-could almost hover! I got some time in piston DC-3 and was an "honorary FE on a DC-4 once. If you wanted one aircraft to do both jobs of data collection & haul bodies I'd favor another Lockheed classic and namesake-a L-188 Electra but I don't think you would ever get one chartered with seats in it without buying it yourself. Anyway, what kind of data would you need to collect? Doug B. *************************************************************************** From Ric Here's my suggestion, subject to comment and correction from the Celestial Choir. The purpose of a reenactment flight would be to answer these questions: 1. You are an experienced celestial navigator on course over the Gilbert Islands on a Great Circle route from Lae to Howland Island. The time is prior to dawn under celestial conditons very simialr to those that existed on the morning of July 2, 1937. With no help from electronic navigation aids, can you find Howland Island within the time allowed? 2. What does Howland island look like from 1,000 feet under sky and light conditions similar to those that existed on the morning of July 2, 1937? 3. Running down a 157 LOP that passes through Howland Island what do Baker, McKean, and Gardner Islands look like from 1,000 feet? 4. Coming up overhead Gardner Island and contemplating a landing in a Lockheed 10, what options present themselves? These are limited objectives. We may or may not be able to duplicate speeds safely and there are many conditions that we won't be able to duplicate at all, but simply re-flying the route and wrestling with problems similar to those facing Earhart and Noonan should prove instructive. We're not going to "prove" what happened with such a flight, but no reenactment can ever "prove" what happened in the past. All we can do is gain a better understand of what might have happened. We can dream all we want to about the cool airplanes we'd like to use, but the fact is that, unless somebody out there is ready to stroke a big check, we'll need to fund this with paying passengers - and that means a big, safe, comfortable airplane.

Was the fuel measured as it went into each of the tanks just as we measure the number of gallons we put into our autombiles or was the fuel just pumped in up to a specific mark in each tank?

There have to be some records of consumption / fuel purchased during the flight. Didn't she fuel up at the military airfield after her flight from Calif to Hawaii?

There is at least one fuel receipt (Darwin) from the second world flight attempt and other bits and pieces of information, but nothing as technical or comprehensive as Johnson's telegrams. ========================================================================= Date: Thu, 30 Dec 1999 14:54:30 EST From: William Webster-Garman Subject: Alternative hypotheses >Lacking a guarantee, he sees all alternative hypotheses as equal. It's a >very common problem. In simple and stark terms, what many folks forget is the role of probabilities. For example, it is possible that Earhart and Noonan were plucked out of the sky by a spacecraft from a distant planet. It is possible that they simply ran out of gas and ditched in the ocean. It is also possible that they landed on Gardner and died later from exposure related problems. However, based on documented history and what we know about our corner of the universe to date, it is vastly (and I mean quite vastly) more likely that they either ditched or landed somewhere. If they landed somewhere, Gardner is by far the most likely candidate, based on the evidence of all the interesting things that have happened there. Some of us believe that at this time a landing at Gardner is a more probable solution to the mystery than a ditching at sea. This estimation of probability is open to change: For example, TIGHAR's own hypothesis on the Earhart disappearance has continued to evolve as new information has been found over the years. william 2243 ========================================================================= Date: Thu, 30 Dec 1999 15:08:45 EST From: Dennis McGee Subject: Midnight ghost I don't know Ric . . . if you can't find a couple of dead Americans on a tiny, little-bitsy, dinky island how do you expect to find dead Frenchmen in the wilds of a humongous place like New Brunswick, or wherever the hell St. John's is? :-) (With sincere apologies to our forum subscribers from "our northern-most state"; I know you're up there, I just don't know where everything is at.)

I sure wasn't going to spend any of my own money for it! I just read the first chapter, and waded through a whole pile of poetic license. The Longs' main thesis is that AE planned her trip based upon maximum range for fuel available, which in turn, is dependent upon head winds. Given the very bad state of knowledge of headwinds across that entire route, why would AE want to do that? Wouldn't it be better to conserve as much fuel as possible under whatever headwinds are out there, provided there is sufficient fuel to reach Howland? If this was really a problem for AE, why did she insist on a West to East journey, where a East to West voyage across the equator gives you the benefit of tail winds, instead of head winds? Based upon my analysis of the Oakland to Hawaii segment, AE used the 150 mph/130knot nominal speed, and did not alter engine speed to maintain a particular speed over ground. Why would she change during the flight later on? I'm sorry, but I cannot accept their basic assumption. Can one of you pilot-eers help me out of this seemingly contradictory puzzle?

There was also a large garbage bag, with food inside left several feet towards the jungle from the fish. What I remember is that the crabs broke into the bag, but didn't carry things out. The crabs also ate the remaining soft parts of the fish, and picked the bones clean, but didn't scatter the bones. Something I also remember was that the crabs which attacked the bag and fish (again, both left on the beach and outside the jungle) were small ones, not the large ones. Could it be that the larger crabs (which in theory would be more likely to be able to scatter larger, heavier human bones) remain in the jungle and don't come out on the beach? When I think of it now, I don't remember seeing larger crabs anywhere on any of the beaches, even though I remember seeing the smaller ones. Hmmmm.... --Chris Kennedy *************************************************************************** From Ric You're right, the delicate skeleton of the fish was left intact. In 1989 we found the remains of a cat in the co-op store (that tumbled down structure just inshore from the landing that wasn't tumbled down in 1989).

Folks, much of what I will say here is based upon my modeling simulations (shared with TIGHAR) and recent material uncovered for the 8th edition. What is beginning to fall into place is that AE and FN might well be on the LOP passing through Howland, but are very far away, well to the SSE of either Howland or Baker, possibly 80 miles away! My monte carlo simulations of the flight indicate a southerly excursion due to the changing wind direction (from the time of 1030 GMT onwards) from that predicted, so that a slight northerly cross-wind component drove them south of the intended flight path. By itself, its kinda interesting, but can also be misleading. Now, Bob Brandenberg has done a marvelous job of radio signal strength analysis, which indicates AE was about 80 miles away at her closest approach to Howland (at one of her radio transmissions). If all of this is true, this makes a lot of sense: why AE and FN didn't find Howland or Baker or see the smoke from the Itasca, it also fits the lack of radio reception after her last message (both frequencies were basically out of range during those times), and it helps AE get to Gardner quicker than expected, as she seems to be well south of Howland, helping out the fuel situation. I'm beginning to become convinced that this might be the right scenario. I wonder how Noonan could be so far off in a N/S direction: the only explanation is that he wasn't able to take a celestial fix at all during the latter half of the flight. That seems sooo strange, but stranger things have happened. The 8th edition is just about done by the co-authors, isn't that right, Ric? and will definitely be worth the price of admission. We're sitting on a veritable gold mine of information, so when will it be ready for publication? I cannot wait!

If I were in AE & FN scenario I would also be leaning the mixtures out just above causing detonation & preignition. The airplane would be many pounds lighter after serveral hours of fuel burn. If lets say they burned off 850 gallons of the useable fuel that would be 5100 lbs less weight the motors have to pull through the air. While I cannot quote anyfigures here I do see a great possibility that they had more fuel available than what previous doomsayers may understand. Did the Electa have EGT gauges for accurate leaning? IT is very well known that as weight is reduced throttles can be moved back for same true airspeed, and higher altitude can also be attained. Any evidence that they might have accomplished this enroute?

Agent Patton's investigation disclosed "no evidence that AE landed at Saipan". Patton,however,cites two Saipanese sources claiming they overheard the Japanese military in 1937 "talking about the crash of AE's plane at Jaluit Atoll". You probably have his full report dated 23 Dec 60: ONI-2345-7(b). I know the current mission of TIGHAR is to prove (or disprove) with credible evidence,either physical or by witness testimony,the hypothesis that AE flew on to NIKU after failing to locate Howland and crashed on or near the Island. I must agree with forum member Dennis McGee.No matter what the millions of hours it will take to estimate within whatever reasonable parameters the Electra's range,if the artifacts and bones can be conclusively linked to AE she made it! If none of the TIGHAR'S investigation yields any viable ,concrete evidence,then move on to other theories. One for instance:re your evidence: a. What is the final expert evaluation by the Cat's Paw people of the Niku heel. Did AE normally with these shoes.Were similiar shoes found in her effects after the crash. Your photo says it was taken ten days before the crash. Did she have more than one pair. Other reserchers say she wore a size 7? What inquiries were made with living relatives? Any effort to locate shoe repair shops ? Any documentation from checkbooks,relatives,friends that she had a replacement heel added? Who took the photo?Many potential inquires left. This evidence may be your best single and irrefutable link to NIKU and AE. This is probably old stuff to you but as you warned,it gets addicting!! Ron Bright ************************************************************************** From Ric No, I don't think we have a copy of the ONI investigation. We really haven't spent a lot of energy collecting background material on the Saipan theory. Never seemed worth the effort. I'll try to answer your shoe questions. 1. <> Remember, there are two heels, only one of which is a Cat's Paw replacement heel. Not much information can be had from the second heel because it has no markings, but the Cat's Paw has been tracked to a mold that was in use in the mid-1930s. The nail holes fit the remains of a hard rubber sole (fragmented) bearing stitching holes that indicate that it was a woman's blucher oxford. A small brass shoelace eyelet seems to confrim that the shoe was a woman's. 2. <> There are many photos showing AE wearing such shoes on the world flight. 3. <> I assume you mean the Luke Field crash. No. She took her personal luggage with her and it was not inventoried by the Air Corps. 4. <> Photos taken during the world flight also show a pair of two tone saddle shoes with light colored soles. 5. <> So did I when I was a kid. Our assessment of Earhart's shoe size is based upon photogrammetric measurement. 6. <> How many shoe repair shops have been around for 62 years? Is it realistic to think that we're going to find some old guy who remembers putting new heels on AE's shoes? 7. <> No. I'm not aware of any such records that could be checked. 8. <> That particular photo is in the Purdue collection.

Our problem is north and south. I can think of no reason to believe they had an east/west problem like that. Perhaps a few miles, maybe even ten if they were having trouble getting more than one sun shot but other than that I'm going to assume they had east/west fairly well figured out. While I'm on that I noticed another comment recently about the wrong position of Howland. Ric, can you resolve this somewhat? My understanding is that Pelligreno supposedly used a map purportedly the same as Noonan's and the plot was within a couple of miles of actual position not the 5 to 7 that has been reported a number of times. Sorry about the use of the words understanding, supposedly and purportedly. Hardly scientific.

It is an average ground speed velocity determined only by an assumed distance covered in a defined time. In other words, it is assumed that Amelia was at or near Howland at 19:12 GMT and she had covered approximately 2,550 miles. In this measure or assessment, she could have experienced headwinds part of the way and tailwinds part of the way. Conversely, she could have encountered varying headwinds. ========================================================================= Date: Fri, 31 Dec 1999 10:24:32 EST From: Tom King Subject: Re: Crab Source The idea that coconut crabs DON'T scatter bones is consistent with the recent observations on Saipan of a couple of murder victims whose remains were left in an area frequented by coconut crabs (albeit in smaller numbers than on Niku). In fact, so far ALL the observational evidence we have seems to suggest that coco crabs don't scatter bones. And yet Gallagher, observing the 1940 bones and the 1940 crabs, assumed without apparent equivocation that it was the latter who distributed the former. That's got to count for something. Bottom line: we need better data, including a controlled experiment.

In Belgium a story goes that the Germans covered an underground bunker at their former airbase at Brustem (which was home of Me-110 nightfighters during the war) before they left in 1944. There are people willing to dig them out but the problem remains who is going to foot the bill. The authorities are not interested as the airfield was closed a couple of years ago and the real estate is up for sale. No investor wants to buy it because nobody wants to pay for demolishing all the the nuclear-proof aircraft bunkers NATO built there in the cold war period. Under one of them, so the story goes, there would still be German aircraft. Of one thing we are shure, however : near the former (allied) airfield B61 in Belgium (which was at Saint-Denis Westrem near Ghent) a Focke Wulf FW-190 is in the proces of being dug out at this moment by a group of aviation historians not unlike Tighar. The plane has been shot down during the surprise Luftwaffe attack on the allied airfields on 1 January 1944 and belly-landed. To get rid of it the farmer on whose field it lay dug a large hole, bulldozed the airplane into it and filled the hole. He grew wheat there for the next four decades. The airplane was rediscovered when the field became the site of a supermarket recently. I haven't seen it but I have seen a picture of the FW-190 which was taken shortly after it belly-landed behind the farm in 1945. If it is found in a roughly comparable condition it was in then, it should be fairly recognizable and fit for exhibiting. So Tighar should take heart. If one day somebody builds a supermarket on Niku (joke) he may well find the remains of an Electra in the woods. LTM from Herman (who lives only five minutes' walking from where the British found their very first FW-190D on that same 1 January 1944.

Sorry it's not technically "published journal". It is mostly the published journal that she and her team kept during the flight for the "education program". Some of the other stuff came from the NASA SSC site at: http://wwwedu.ssc.nasa.gov/htmls/tseierc/flight.htm#Menu What I mistakenly called "Finch's published journal" came from the education site maintained by the "Tech Team". It is that site that has "comments" from her reports and journals. Mostly updated daily as the flight progressed. The tech team site (and you probably have it already) has the daily summaries like this one (extracted from it). "......The 2,000 mile trip across the Pacific Ocean to Oakland, California is the most dangerous flight so far. The plane, filled with enough fuel for the 15-16 hour flight, will weigh 17,000 pounds. On an average flight it weighs about 12,500 pounds. Linda Finch says, "It is dangerous. We'll be pushing the parameters of the plane so outrageously. But as long as we manage it,well, ...we'll be fine." Takeoff is critical. "The gear is not designed to take off with that much weight," she said. "The airplane will have to be travelling 100 mph before we get off the runway." The normal takeoff speed of the Electra is around 65 mph. Once airborne, Linda will climb slowly. She will have just enough fuel to make it across the Pacific. If there is any sort of a head wind, she will have to turn back and try the flight another day. ......" Sounds over dramatic, perhaps, but does Collopy's description of the last take off ring any bells? This is another example: "Dateline: May 18, 1997 Current Coordinates: Latitude 1° 20' N , Longitude 172° 50' E Point of Departure: Nauru, Oceania Destination: Tarawa, Kiribati Local Weather Conditions: 86° - 75° F, Partly cloudy with afternoon showers Distance Travelled: 392 nautical miles Air Time: 2 hrs., 45 min. Summary of Events: Flight log excerpt - We landed at Nauru on Friday night. There were a few rain showers on the flight into Nauru, but they cleared by the time we landed. The plane leaks badly at the windows, so I have to tape the windows every time it rains. Saturday in Nauru was spent fueling the planes from barrels. We only had 600 gallons so it took about 1/2 a day. I spent the afternoon shopping for food, water, sheets, and stuff to cook with when we get to Kanton. ......." And this one: "Dateline: May 19, 1997 Current Coordinates: Latitude 2° 20' S, Longitude 157° 40' W Point of Departure: Tarawa, Kiribati Destination: Kanton and Christmas Island, Kiribati Local Weather Conditions: 87° - 76° F, Partly cloudy with afternoon showers Distance Travelled: 1,100 nautical miles Air Time: 7 hrs., 12 min. Summary of Events: World Flight 1997's pilot Linda Finch and navigator Peter Cousins have completed their fly-over of Howland Island in memory of Amelia Earhart. While flying over Howland Island, Pilot Linda Finch dropped three memorial wreaths from the plane's window-sized removeable panel adjacent to the right rear window. This panel was also in Amelia Earhart's plane and was used by Fred Noonan to take celestial navigation sightings. The wreaths included Linda's own personal memorial, one of silk flowers decorated with pearls from the Mayor of Atchison, Kansas, birthplace of Amelia Earhart, and a Laurel leaf memorial from the Zonta Club. To avoid the introduction of foreign plant species in the region, none of the wreaths contained live plant material. A swift tail wind then set them on their way to the island of Kanton, but then Linda Finch and navigator Peter Cousins opted to depart Kanton Island a day early and landed today on Christmas Island (also known as Kiritimati Island)...." I assume everyone has have already seen all this? but just in case... http://www.flinet.com/~techteam/flight.htm The same stuff is kept up for the whole flight. I was interested in the average speeds and distances as they vary considerably. Also in comparing the weather conditions and temperatures there (equator) with here (20S). They are pretty consistent down to the dates. I also lived at around 10S for a while so it is of interest to me as an occasional (too occasional) pilot flying in this stuff. Interesting that the temperatures are highest to lowest.? Possibly on ground, then in air. 87deg is fairly warm (it's currently 82deg in my office at 8.55am with the windows open) If I close the windows and run the air conditioner it might get down to 78 or a little lower by noon. At that temp it feels refreshingly cold! So going from 87 to 76 degrees OAT would put Finch at 5500ft. I'd also like to know the octane rating of the fuel used in the restored engines. P&W just might be interested in sharing the figures. I wonder if there is a modern day equivalent of the settings recommended in the Kelly Johnson figures? Also P&W might give an insight into the difference in performance (cruise anyway) of the engines with higher octane fuel. RossD *************************************************************************** From Ric I'm surprised by the 17,000 pound takeoff weight. That's awfully heavy. I wonder if it's accurate. The bit about the removable panel is pure folklore. NR16020 had a big window installed on the aft starbord side prior to the first world flight attempt. It was skinned over sometime between the completion of repairs on May 19 and the departure from Miami on June 1st. There is no evidence that it was ever a removable hatch. ========================================================================= Date: Fri, 31 Dec 1999 11:25:19 EST From: Ross Devitt Subject: Re Fuel Capacity Tanks are usually filled to a point and then "dipped" with a stick and the wet mark shows the useable gallons in the tank. Aircraft fuel tanks are not filled "to the brim" as a rule because due to their standing in the sun the fuel expands. The design of the tank fillers is such that you can only fill to the bottom of the filler neck. This allows an air space where expansion can take place after the caps are replaced. The fuel filler caps as well as the tanks themselves are "vented" to allow for this expansion. RossD ************************************************************************** From Ric Well, in 35 years around general aviation airplanes I've filled many a tank to the brim and can hardly ever remember "sticking" a tank.

The radio equipment of Earhart's day drew MUCH more current than any of the modern equipment that we have today, so there's really no comparison between her equipment and modern equipment, in terms of current drain. Specifically, I believe that Earhart's radio was powered by a dynamotor, which converted the lower battery voltage up to the higher voltages required for the tubes in the radio equipment. If I'm remembering correctly, those dynamotors drew LOTS of current. John - KR0Y ************************************************************************** From Ric The Electra's radios were indeed powered by a dynamotor located under the pilot's seat. ========================================================================= Date: Fri, 31 Dec 1999 12:34:27 EST From: Ric Gillespie Subject: Re Ludolph sextant Wes Spreen responds to Tom King's question.

Is Long's book being accepted as the "solution" to AE's disappearance by any official or "semi-official" agency, government or otherwise? Regards, Jim Razzi *************************************************************************** From Ric As far as I know, there is no official or semi-official or quasi-official agency that makes such judgements. I suppose some may regard the Smithsonian to be the U.S. government's voice in such matters. The National Air & Space Museum's chairman of Aeronautics, Tom Crouch, has been a vocal supporter of the crashed-and-sank theory and he agrees with Elgen Long, but not even Elgen claims that his book (despite its title) should be taken as the final proof of anything. The claim of "solving the mystery" was the publisher's idea and Elgen was simply not careful enough in negotiating his book contract to keep them from having the right to do that. In terms of public impact, the book has caused less stir in the "Earhart community" than any of the other recent books. We've probably talked about it more here than anybody anywhere.

Randy's modeling work is very interesting. Sounds like you have a proponent of Monte Carlo methods right there in the TIGHAR's den. As Randy notes, you have to pretty much accept the fact that their celestial nav broke down to some degree for this to be possible. If that were the case, it is possible that Noonan might have shifted their targeted arrival point away from Howland to something roughly halfway between Howland and Baker. Given 15-20 mile visibility (which might have seemed reasonable), that would create a backstop of some 70-80 miles (approx) in length across their path where either of the islands should have been visible. In other words, if Noonan felt the nav accuracy was deteriorating (but visibility near sea level was good), he might have opted to increase his chances of making landfall by going slightly off course to widen his target area. This would place them on a course roughly 18 miles south of Howland. If they were flying by DR, the crosswinds that Randy postulates might already have had a head start on drifting them southward. Just a thought. On another subject, my understanding is that Noonan had 2 chronometers, a bubble sextant and a marine sextant as backup on board. I have several marine sextants, but know very little about aircraft types. 1. Anyone familiar with brand and the performance characteristics of Noonan's bubble sextant? How accuracte were they (generally)? How high an altitude could be reliably measured? Did it have a chronometric averager or could you just snap a quick sight? Even if it had a chronometric averager, could you override it if you had limited sight time? Were they reliable (not prone to missalignment or other problem during normal handling that would render them useless)? Would it be unusual to carry just one? 2. Has anyone out there ever actually tried using a marine sextant from an aircraft? What was the result? Happy New Year, Tom MM ************************************************************************** From Ric The Monte Carlo simulation that Randy was involved in was done by a company called Wagner Associates in California as part of their effor to sell the Navy on their program. I can't answer your questions about Noonan's bubble octant. We don't know for sure what type of instrument he carried. We do know that just prior to the first World Flight attempt, a Pioneer bubble octant was borrowed from the Navy by Harry Manning (at Noonan's insistence) and that the instrument was signed over to Noonan when Harry left the team following the Luke Field debacle. It seems likely that Noonan used that same instrument on the second attempt but we don't know that for sure. As for the number of chronometers, it would seem prudent to carry a spare but Chater's references to Noonan's "chronometer" are all singular.

Not necessarily. I use to consistently work another station, 300 miles from my location, for up to one hour at a time, with VERY strong signals, in the 40 meter (7000 khz) amateur band. Such HF radio propagation is not uncommon. John Rayfield, Jr. - KR0Y ************************************************************************** From Ric Anyone familiar with the vicissitudes of HF signal propagation will be amused to study the logic presented in Long's book which purports to track the flight's precise progress by assigning hard distances to various signal strengths. ========================================================================= Date: Fri, 31 Dec 1999 13:10:43 EST From: Randy Jacobson Subject: Re: Long's Book Thank you Alan, for restoring my faith in basic humanity. I wonder what Long would have had AE do if she was to encounter 150 mph headwinds all the time: to burn up even more fuel to get maximimum range, even though she couldn't possibly make it to Howland in that case? Gees, I just can't believe he made a boner like that. He did get the Natal to Dakar fiasco right, though! ========================================================================= Date: Fri, 31 Dec 1999 13:15:26 EST From: Randy Jacobson Subject: Re: Where were AE and FN on the LOP?

In reality, they helped write the program with my guidance on parameterization, but I did all of the modeling runs and interpretation. The Navy is well aware of Monte Carlo techniques, and has been for many many years. *************************************************************************** From Ric Thanks for clearing that up.
