Continuity mistake: When Will Stockdale is at the Purple Grotto, at one point the cup full of liquor is at different levels.
Factual error: An Air Force pilot ends a radio conversation with Will Stockdale by saying "Over and out." He should have simply said "Out," which means "I am done speaking and I am ending this communication." "Over" means "I am done speaking. Please respond." No real pilot would say "Over and out."
Factual error: While a car radio is playing, the announcer identifies the station as WQUID. United States radio stations are identified by three letters or four letters, never five.
Factual error: The sergeant in the opening credits is not Air Force as the badge is reversed. Air Force are point down and army is point up.
