WELL, EXCUUUUUUUUSE MEEEEEEE 
I'm certainly not gonna argue the specs of this plane with you but I was using the figures from the C-75.
You're such a nit-picker!
Me a nit-picker??? I wasn't the one that brought up all this plane to Los Angeles business, and detailing Hagen's movements

If I wanted to nit pick (by the way what is a nit and where do you find them

), I would have asked how come all this took place in 1945 when in fact the whole scenario revolved around what is to be believed Frank Sinatra getting the part in "From Here to Eternity?" happened in 1953?

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.
