Character mistake: RAdm Tarrant (Frederic March) is on the command deck watching the helicopter land. He's wearing a ball cap with his rank insignia, 2 stars. But they're inside down (points down).
Trivia: Although the carrier used in the movie was the U.S.S. Oriskany, for the film it was given the fictitious name of U.S.S. Savo. I do not know why that name was chosen or by whom, but it was a very ironic choice. Although many U.S. carriers have been named after famous battles that were American victories (including Oriskany), the Battle of Savo, early in WWII, was one of the worst defeats in the history of the U.S. Navy.
