Factual error: Contrary to popular belief, sudden cabin depressurization in a jet plane will not cause anyone to be sucked out of the plane (unless they are sitting right up against a blown-out window), nor will it cause the aircraft to go out of control or crash.
Factual error: Charlotte tells the sheriff that when her cousin Miriam arrives, she will know how to handle the County Commissioner. Louisiana doesn't have counties. They have parishes. (00:25:25)
Factual error: An Air Force crewmember is playing pool in the ready room. He hits a striped ball with his pool cue instead of the cue ball.
Factual error: During the scenes with the armored train, a USATC S100 can be seen. This should not be possible as the S100s were American locomotives sent to the Allies during the war and would not have been in France at the time. They only arrived in France after WW2.
Factual error: The movie shows a 'jet' aircraft belonging to 'consolidated airlines'. The so called airplane is a laugh. It has two jet engines attached to the horizontal stabilizers. The landing gear appear to be bolted to the wings. During the movie this plane crashes and the engines are moved to a terminal to be examined. They are too small to be real engines. During the course of examining the engines, they are run inside the terminal building. One of the investigators stands 10 feet behind the jet intake and is not sucked inside. The cockpit is not even close to what one would find in a jet airplane.
