Other mistake: In the air combat part of the film, there are two close-up shots of an attacking plane which is a P-47 Thunderbolt. Also, in a couple of brief shots of a single aircraft attacking from the rear, it's definitely a Spitfire. The Spitfire at 01:44:53 and the P-47 at 01:47:07. (01:44:53 - 01:47:07)
Visible crew/equipment: After the opening credits and intro at the start, in the first shot, just before the 'Britton and Sons Hats' glass door begins to open inward, the reflection of the camera and cameraman can be seen on the glass surface. (00:01:40)
