Factual error: During WW2, 16 B-25s were loaded onto the USS Hornet at Naval Air Station Alameda. All 16 of the planes were placed on the deck, as B-25s were too large to fit in the below deck hangar space. In the movie, when the USS Hornet and USS Enterprise are shown together, just prior to launching the raid, there are only 14 B-25s on the deck.
Factual error: Captain Bernard Rawlings, the British naval attaché in Tokyo at the beginning of the film, wears no medal ribbons. In fact, as depicted in photographs, Rawlings would have had several ribbons by that stage, including First World War service ribbons and the OBE he was awarded in 1920.
Continuity mistake: The ack-ack Japanese gunners seem to be the same 2 on numerous ships and carriers. One grits his teeth and the other has a long concentrated look.
Factual error: They show several scenes of Pearl Harbor after the attack where there is no indication that anyone is observing blackout regulations when in reality the whole island was under blackout conditions afterwards.
