Continuity mistake: Throughout the film Maverick's plane has the number "114" on it. However, at the end when he is waiting on deck, the number has changed to "104". This is actually Iceman's plane, which has already taken off. When Maverick launches, the number has changed back to "114" again.
Continuity mistake: The Navy allowed only two live missile shots (one AIM-9 Sidewinder and AIM-7 Sparrow) for the filming of the movie. Maybe that is why we see so many missiles fired from an empty rack.
Continuity mistake: In the volleyball scene, Maverick can be seen looking at his watch because he has a hot date with Kelly McGillis, however while they are actually playing, it is easily noticeable he is not wearing his watch in some of the shots.
Continuity mistake: In the elevator scene with Maverick and Charlie, Tom Cruise's hair keeps changing. Both Tom Cruise and Kelly McGillis were working on different movies when they added this in. Kelly had her hair dyed a different color and Tom's hair was longer.
Continuity mistake: In the final battle scene, which takes place way out over the water, in some of the F-14 shots, mountains can be seen in the background.
Suggested correction: How is this a mistake? The aggressors would have to come from a land base so there is every possibility of mountains being visible.
They are based in San Diego, Miramar Naval Air Station. Mountain can be seen from there but not what was filmed. Mountains shown are in Nevada.
Continuity mistake: When Maverick rides his motorcycle up the hill to Charlie's house, the sun is just about to set in the background. He stays at Charlie's a while, they drink some wine, then he leaves. As he is leaving, the sun is still setting in the background.
Continuity mistake: In the dogfight where Cougar freaks out, when Maverick and Goose fly upside-down to give the MIG the birdie, the names of each pilot are not only upside down, but they are mirrored too. If you look at the names upside down, you can't read them.
Continuity mistake: Before the final dogfight the horizontal stabilizer (back wings) on Mav's jet say YYY, afterwards they say XXX.
Continuity mistake: After the final dogfight, how did the drop tanks get back onto the planes before they landed? They sure weren't there during the dogfight.
Continuity mistake: When the instructors are out on the flight line discussing Maverick's loss of confidence, in each shot Viper's sunglasses can be seen to alternate between Randolph (square type) and then Ray Ban (aviator style).
Continuity mistake: At Charlie's, she and Mav are having dinner and he asks for the wine. Throughout the entire scene the bottle of wine keeps getting rotated from shot to shot.
Continuity mistake: The weapons armament on the F-14's keeps changing from one cut to another.
Continuity mistake: During the second dogfight, Iceman shuts down one of his engines, but when they fly past the carrier while returning, there are two lines of smoke coming out of his plane.
Continuity mistake: If you notice Charlie's (Kelly McGillis) car, the DoD base's name sticker is blue (on her car, it is in the lower left corner). Blue is reserved for Officers. It should be green (for civilian employees).
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: Maverick is shown wearing a black wristwatch, but on the closeup shots of his hand on the throttle, the watch is silver.
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.
Suggested correction: While it's technically correct that they have to wear Nomex flight gloves for taking off and landing, I know many jet jockeys who choose to ignore this rule.
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 Top Gun School, when Maverick does his "hit the brakes and he'll fly right by" move, watch close and you will see part of the canopy moulding fly off the cockpit as the nose comes up.
