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: You can't be dyslexic and become a pilot, no matter how good looking you are or how much you impress the nurse. Apart from the literature which you have to be able to read and understand to pass your ground exams you would be unable to read a map accurately. Rafe is not mildly dyslexic. His dyslexia is so severe that he cannot even read an ordinary eye chart.
Factual error: In the scene where Admiral Kimmel is inspecting the crew of the battleship an aide comes up with a message to send some ships to the Atlantic. Admiral Kimmel starts complaining about the orders. No Admiral would ever do this especially in front of enlisted men. In fact he was placed in charge of the Pacific fleet when his predecessor complained about moving the fleet from San Diego to Pearl Harbor.Clarence Daugette
Continuity mistake: When Rafe and Evelyn go to the Queen Mary ship and they are rising on the platform, and kissing, one camera shot shows them rising and when they stop the camera does a close up and you can see they are still at the red painted water line indicator. The next shot shows them above it again.
Factual error: The nurses are wearing far too much make up when on duty: bright red lipstick, eyeliner, mascara and blusher expertly applied. Military medical nurses are allowed subtle skin tone make up and surgical nurses none at all. It's always been that way, right back to the 1890s when the British Army first hired nurses.
Factual error: The P-40s depicted in the movie were later models that were not around during Pearl Harbor. The ones used in filming were probably either P-40Ks, P-40Ms, or P-40Ns instead of the historically correct P-40Bs or P-40Cs that were around at the time of the attack. This is noticeable because the planes in the movie have three guns mounted on each wing while a correct P-40 would have two mounted on each wing and two on the engine cowling.
