Un yankee dans la R.A.F.

Tyrone Power's flying stunt double in this movie, RAF pilot Lt. Harold Barlow, was shot down by German aircraft and taken prisoner, according to a 20th Century-Fox press release of 24 January 1942.

The following items are 'goofs', but may have been made deliberately by the filmmakers in the interests of war-time security: The real 61 Squadron flew Hampden bombers, not Lockheed Hudsons. Hudson bombers were not used in bombing missions over Berlin, with the main role for these bombers being in Coastal Command in Europe. The real 32 Squadron, which Baker flies with in the Dunkirk scenes, flew Hawker Hurricanes and not Spitfires. When Baker gets in the Spitfire, it carries the squadron code 'LO' which was the code of the 602 Squadron and not the 32 Squadron he is supposed to be flying with (it used KT and GZ). 602 Squadron aircraft were used for shooting the film at Prestwick
