Hum---. If I can weigh in here for a second.
Personally, I saw more in the original video and stills than the VII video. Sorry---maybe because I got older in the process. Several of us, looked at those pictures and 'saw' some very interesting things, some of which may have been aircraft parts. (What's the black squiggley thing?) Some of us even talked to Jeff Glickman about them in DC, and frankly got a very non-committal answer. Jeff is like that! Our friends Richie and Jeff Victor spent hundreds of hours 'analyzing ' those frames. Many new members since them, John, Tom, Tim, etc. have done the same with the VII video. I wasnt on KOK, Tim was. Apparently he was watching the LIVE feed from the ROV/AUV as they were doing their thing. The rest of us are watching a video of the results of those searches.
First---congrats to Tim for being able to go on the expedition. 2nd-for being able to see first hand the operation in real time. That brings up and interesting question: in viewing it real time, did you see anything THEN that got your attention? I'm assuming NOT, because if there was, then a more detailed search would have been called for at that location. That was why TIGHAR went out to Niku, to gather real data.
As we have seen from the pictures and video, the underwater topography is something to behold. Amazing is probably not the proper adjective to use to describe it. Scary environment is close. We all have had our own opinions about what to expect. We all wanted to find this large piece of a wing with part of a N number on it. Obviously it isnt sticking up from the reef, OR the bottom (wherever that is) with a marker beacon flashing, "here I am". Its there, somewhere. That somewhere is the big haystack in the Pacific, that we think is the waters around Niku. Maybe, maybe not. With what I've seen in the video, the ROV could have missed it by 2 feet or 2 miles. The result is the same---it wasnt found. So, to echo Jeff Nevill---its hard to see another expedition go to Niku without dedicating sufficient time and resources to do a really thorough surface, and subsurface search. Dr. King and his group could search the North west part of the island, as well as areas leading back to the 7 site. Gee---maybe also the southern part of the island. Another team could be working on subsurface searches. The problem isnt time, unless you factor in the every day the artifacts that we search for are either deteriorating, or becoming hidden from view. No---the problem is the amount of money it would take to send a full scale search effort to Niku for 2-3 months to do the job. More than several million I'm sure.
Perhaps there are some deep pocketed benefactors out there, as well as others that have the means to see this through to a "breaking news announcement".
