Character mistake: In the scene where Maverick flies into Iceman's jetwash, as they are descending, Maverick calls out the altitude as 6,000 however the metre is displaying between 2,000 and 3,000. (01:04:25)
Character mistake: In the opening scene is a paragraph describing why the Top Gun school was started. The word "insure" is used when the word should have been "ensure". They wanted to guarantee the U.S. had superior pilots, not take out an insurance policy.
Character mistake: In the military, at the time of filming, basic protocol was that you wear your "cover" or hat when outside. When walking back from Goose's funeral, outside, Tom Cruise is carrying his hat.
Suggested correction: Goose's funeral is not shown in this movie.
Character mistake: The Commanding Officer, CDR Metcalf (Viper), is wearing is CO pin under his ribbons on the left pocket. That means he used to be a CO, but is not currently. He should be wearing it over is right pocket to show that he is currently a commanding officer.
Character mistake: In the elevator scene the elevator stops and a commander steps in wearing his hat. Hats are only to be worn inside unless a person is under arms.
Suggested correction: Insure and ensure are equivalent in US usage, and are from the same Anglo-Norman root.
Having the same root word is irrelevant. Many distinct words have the same root. In the US "insure", "ensure", and "assure" are not equivalent, therefore this correction is not valid. One could argue that "insure" was used to mean to be protect against risk as "insure" doesn't specifically mean "take out an insurance policy." But generally one would use the phrase "insure against."
