Factual error: Two of the gunners are Privates. The minimum rank for aircrew was Sergeant.
Character mistake: Flight Lieutenant Williams is addressed as "Lieutenant" a couple of times. RAF (or RNZAF) flight lieutenants are always addressed by their full rank.
Factual error: Both Flight Officer Garrett and Flight Lieutenant Williams address Captain Reeves as "Sir," despite holding the same equivalent rank. Garrett may not be aware of this (as she is actually only pretending to be a WAAF officer), but Williams certainly would be.
Character mistake: The crew deride Garrett's title of Flight Officer, claiming that she can't have it because she hasn't flown in combat. In fact, Flight Officer was a genuine WAAF rank corresponding to Flight Lieutenant. Many RAF officers holding the ranks of Flight Lieutenant, Flying Officer, and Pilot Officer were not aircrew, despite their titles.
Factual error: The American flag shown in the animated sequence at the beginning is the modern 50-star version rather than the WWII 48-star version.
