Factual error: In the scene where the nurses walk among the flag-draped coffins after the attack, the nurses are in stylish civilian outfits. Those nurses are all Naval personnel, and once war was declared they were ordered to be in uniform at all times, except when in the privacy of their quarters.
Factual error: Shortly after our hero ejects you see the pilot flailing around trying to pull the ejection handle. In a Navy aircraft with two crew, the NATOPS manual (Naval Aviation Training and Operations Manual) clearly states that the seats must be set in the "command eject mode". This means, regardless of who initiates the ejection procedure, the rear seat goes first, followed by the pilot 1/2 later. There is no need for the pilot to pull the ejection handle.
Factual error: In the first 15 minutes of the movie, a Delta Force operative is seen wearing a pair of Oakley X-Metal Juliets. The events portrayed in the movie took place in 1993. Oakley didn't make the Juliets until 1999. (00:05:02)
Factual error: During the first scenes of the film the Greek flag used is the current one, and not the one used at that time. The flag that should have been used is a white cross on blue.
Factual error: Reference the rural scenes. In the 40s, barley fields did not exhibit large perpendicular tracks made by crop sprayers.
Factual error: In the scene where the resistance blow up a German train, the locomotive is a British one. The number is shown as 92240. This engine is owned by the Bluebell railway, who are named in the credits. It wasn't even built until around 1955. It seems to be the same engine pulling the train to the concentration camp later in the film. Remarkably fast repairers, those Nazis.
Factual error: The corporal mess steward addresses the sergeants as 'sir'. British sergeants are never addressed as 'sir'.
Factual error: At the beginning of the movie there is information, that "Poland surrenders to the Germans after less than a month of fighting." In fact, the last big battle during Invasion of Poland (Battle of Kock) took place between 02-05 October, more than a month after first shots were fired.And Poland also never officially surrendered to the Germans.
