Thanks Marty. It's actually Noorduyn, not Noordyun.  I've been spelling it wrong.

The "Norseman" was a 1934 Canadian design intended to be the ideal bush plane.  It's a very basic fabric-covered steel tube and wood construction, ten-place airplane - single engine, fixed landing gear, high wing, strut-braced monoplane with a big door on the left side of the fuselage for easy loading of people or cargo. The engine was the ubiquitous Pratt & Whitney R-1340 AN-1 WASP rated at 600 hp for takeoff (basically the same engine as on NR16020).  Most had two-bladed props but some had three blades. Not sure why.  Covington Aircraft Engines in Oklahoma is the world's largest overhaul/re-build facility for P&W radials. I asked my friend Blaine Abbott at Covington why you'd hang a three-blade prop on an R-1340.  He said the geared AN-2 version of the engine takes a three-blade prop.  He said a three blade prop on an AN-1 would be rare, but a 1943 vintage beautifully restored Norseman currently for sale has a three-blade prop on an AN-1 engine. It's an issue because the fisherman remembers a three-blade prop on the plane he hauled up.

Beginning in 1942, the U.S. Army bought a total of more than 700 Norseman as the UC-64A. On June 30, 1944 the "U" designation was dropped and the UC-64A became the C-64A. Most were used in Alaska.  According to Spragg, 212 C-64s served with 8th and 9th Air Force in the ETO. They were used as utility transports assigned to bomb groups and repair facilities.  Think of them as pickup trucks.

The airplane carrying Glenn Miller was C-64A serial number 470285 assigned to the 35th Air Depot Group and Depot Repair Squadron of Eighth Air Force Service Command, 2nd Strategic Air Depot based at Abbotts Ripton, aka Alconbury, airfield. The 2nd Strategic Air Depot handled service and repair for 1st Air Division B-17s.

There's a 1943 Operator's Manual for the UC-64A at http://www.avialogs.com/index.php/item/56039-t-o-01-155cb-1-pilot-s-flight-operating-instructions-for-c-64a-airplanes.html

Perhaps the most important thing to remember about the C-64 with respect to the Miller flight is that it has no de-icing or anti-icing capability.

Subject fixed--on the second try.   ::)

Among my RC friends, 3-bladed props were recommended in situations in which a 2-blade propeller of comparable load would be too long for the landing gear.

I've read that the most efficient prop is one-bladed.  The Internet is divided on that question.

An F2A World Record was set in 2001 for control-line speed using a one-bladed prop.

"36,000 RPM, 1 Blade Prop, and 208+ MPH Control Line Model Airplane."

The video is very entertaining.

It's not the only strange feature of the airplane.  It also has just one wing and one stab.

I suppose the important point is not what is actually true about the merits of 2- vs 3-bladed props, but what the US Air Force believed about the merits of the prop swap for the C-64 in 1943-1944.

Alchetron:

"It was a UC-64A Norseman (s/n 44-70285) flown by F/O John R. S. Morgan in which Major Glenn Miller was flying as a passenger when he disappeared over the English Channel on December 15, 1944."

From Ric:

Somewhere Spragg got the idea that 470285 was a C-64B, but if you go to JoeBaugher.com, you'll see that the aircraft was clearly a C-64A produced in Fiscal Year 1944. 
JoeBaugher.com:

"70285 (MSN 550) Delivered to USAAF July 5, 1944; Newark, New Jersey July 5, 1944; shipped to the 8th Air Force, England July 14, 1944; 35th Depot Repair Squadron, Abbots Ripton, Cambridgeshire.  Disappeared over the English Channel on December 15, 1944 while en route from Bedford, England  to Paris, France. Band leader A. Glenn Miller was lost along with the pilot John Morgan and  Lt. Colonel Baessell. The pilot departed Abbots Ripton at about noon on the 15th with orders  to pick up his passengers at Twinwood Farm, a satellite to RAF Cranfield, located three miles  north of the centre of Bedford. After picking up Lt. Colonel Baessell and Major Miller, it  departed for Villacoublay, France in marginal conditions, with Bordeaux being the aircraft's  ultimate destination; Villacoublay was located some ten miles southwest of the centre of Paris.  The aircraft was never heard from again.  No trace of the aircraft or its occupants has ever been found."

There were only ten C-64Bs, 2 in FY 1942 and 8 in FY 1943.  All were transferred from the RCAF to the USAAF.
