Corrected entry: When Hughes is with his staff and they're watching the Jane Russell movie (while Hughes is trying to talk to them about his ideas for the plane), the same part of this movie is played twice during this scene.
Corrected entry: When Howard Hughes is starting the Spruce Goose his engineer says "A-OK." It is well documented that this expression was first used during the Mercury space program, over a decade later.
Correction: The exact words uttered when the engines are firing up is "Engine 1: good. Engine 2: good. Engine 3: good. etc." Not A-ok.
Correction: Correct, but not a mistake. Notice that just after the second sighting of the 'tucking into bed' shot, the end-of-roll markings flicker by, then another shot begins. They are watching clips from the unfinished film, not the finished product. In fact, while these scenes play, Howard is discussing a revised bra he wants Jane Russell to wear in future shots. Therefore, there is no mistake here.
