By the way, why did you use the specifications for the C-75? Is that the plane that was shown in the film clip?
I always thought it was a Lockheed Constellation, of course I could be wrong, and it wouldn't be the first time.
Dunno what plane they showed in the movie but I used the C-75 figuring it would've been the aircraft that was being flown in 1945. You're the expert, not me! I'm only guessing.
