Factual error: Two of the gunners are Privates. The minimum rank for aircrew was Sergeant.
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.
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.
