Continuity mistake: The class at Top Gun was made up of the current best pilot/RIO air crews which had not previously attended the school, from various squadrons. At graduation, out of all the pilots in the Navy, including all the pilots from Maverick's squadron still on the carrier (some of which would have already graduated from Top Gun), Maverick, Iceman and Wolfman have to rush back to Maverick's aircraft carrier because they are the only pilots available that can go against the MiGs?
Continuity mistake: In the first dogfight, when Cougar freaks out he removes his face mask. When Maverick takes-off again to guide him down the shot shows Cougar and Merlin's plane from the side where Cougar is again wearing his mask. Then it cuts back to a face shot of Cougar and his mask is off again. (00:09:35 - 00:11:00)
Continuity mistake: Take notice of everyone's hands during the action sequences. No one is wearing gloves. As standard issue for military pilots, the gloves are made of Nomex and provide protection from fire and allow for a better grip when things get a little hot and heavy.
Continuity mistake: After the final dog fight where everybody is happily back on the aircraft carrier, Iceman exclaims: You can be my wingman anytime, and Maverick replies: Bullshit - you can be mine. Then they hug, and during that hug Iceman in someway manages to put his sunglasses on, from one cut to another
Continuity mistake: When the four pilots are playing volleyball, they have no sand sticking to them even though they are shirtless, sweating, and sometimes diving in the sand.
Continuity mistake: At the end of the briefing before the final scene, Iceman questions Maverick's capabilities. He's right to do so as Maverick can't make up his mind what aircraft he's supposed to be flying. First we see him climbing into the cockpit of an F-14, then when the aircraft is placed on the catapult, it changes to an A6 Intruder. When the order is given for Alert-5 launch, he's flying an F-14.
Continuity mistake: The flight where Goose dies begins over land - where the pilots are chatting. When they see the enemy they are over water. In the next shot they are over mountains and desert again, until they land on the water. That doesn't add up. There are no places in California where the desert goes all the way to the coast with no towns at all.
Continuity mistake: In the opening scenes of the movie, they show a number of planes landing and being prepped for takeoff. One of the planes landing has the number 114 clearly shown on the right side. This is Maverick and Goose's plane. Why is it landing when two minutes later they're on patrol 250 miles from the carrier?
Continuity mistake: Scene of Tom's last take off - the Tomcat's tail number changes before he lands OR TC changed planes mid-air.
