Having seen the film last night (and noticing that a couple of other flying buffs were also have been in the cinema, hanging on until the last credit to see who had helped out with the various scenes) I can only ask :
The scene where they are standing in front of several grounded TWA Super Constellations (in the 1960s Connie livery I believe !) looked just too realistic to be models. Where did they shoot this ?
The Racer looked pretty real, not always a model, as well. Did they adapt something to look like it ?
The XF-11 went from an 8-bladed prop to a contra-rotating one. The latter looked like a model or even computer simulation, but the former looked real enough. A full size mock-up ?
