Factual error: When Top Gun first came out, everybody in our squadron made a big joke of the "Deadly Blue Tubes." This refers to the sidewinder missiles that were supposedly launched from the Tomcats. Those who are familiar with aircraft weapons, would know that the blue tube is a sidewinder simulator. If you were to launch this from the aircraft, all it could do is drop like a rock.
Factual error: In nearly every cockpit scene, regardless of fighter airframe, you can see that half or more of the lights on the caution lights panel on the lower right-hand side of the cockpit are lit. These lights are the illuminated names of all the systems that are not currently operating, ergo if the "Engine 1" light is lit, then Engine 1 is not running. If over half of the lights are lit (as in the cockpit scenes) then the pilots must be flying without half of their systems running, including engines, hydraulics, and radar. None of these lights should be on in flight. This makes it obvious that the scenes were shot on the ground using external power.
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.
Factual error: In his first flight at TOPGUN, Maverick and Jester are seen flying at low level, yet there is a 10,000 foot hard deck, so they must be flying over mountains that height above sea level, in which case the hard deck to be any use would have to be higher.
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.
Other mistake: During the final dogfight, the same shots of missiles flying through the air are used several times.
Factual error: Every time one of the F-14 pilots fires a missile, he thumbs the selector switch on the stick to the SP/PH (Sparrow/Phoenix) position, then pulls the trigger. In every case, it's a Sidewinder that leaves the rail, even though it isn't selected, and would not have had time to "home" anyway.
Audio problem: Reference the dialogue in the hangar where Mav/Goose and Charlie are discussing what was happening when they met the MiG, and Goose says "You know, the finger." In the original 1985 cinema release, Charlie replies "Yes, I know the finger, Lieutenant," but in the video release this has been changed to "Yes, I know the finger, Goose." If you look closely you'll see that her lips don't move when she enunciates the word "Goose," and if you listen carefully you can hear the edit change in the soundtrack between "finger," and "Goose."
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.
Factual error: The implausibility of holding class in a hangar instead of a classroom has already been mentioned. But how about the desk just inside of the hangar doors, complete with blotter, "in" and "out" baskets and other accessories?
Factual error: Although it doesn't occur in the land-based tower at Miramar during Mitchell's first high-speed pass (thankfully), when he repeats the pass at the carrier, the camera work tries to make it look like the jet rocks the tower. US super carriers displace over 100,000 tons, and are not pushed around even by 30,000 pounds of thrust flying nearby.
Factual error: When Mav explains to Charlie his dogfight with the MiG-28, Charlie asks him: "You were in a 4G inverted dive with a MiG-28?", "Yes Ma'am" he replies. Imagine the two aircraft. The F-14 was inverted (the back of the F-14 was "looking" at the ground, and it was pulling 4 positive G's), and the MiG-28 was flying horizontally (belly of the MiG-28 was "looking" at the ground) so it should have been pulling 4 negative G's to keep their distance constant, or more to increase it (otherwise they'd have collided). For the MiG to pull 4 negative G's is almost impossible for two reasons: 1) the negative g-limits of the aircraft are somewhere in the area of 3.5, and 2) the Russian pilot's eyes would have popped out of his head at this g-force. Even the most modern and agile fighter aircraft of the world (like the F-16 and the Eurofighter) have a negative g-limit of 3.5 while their positive limit is at 9, mainly due to human body constraints.
Factual error: In the final dogfight scene, the Search and Rescue helicopter lands with rescued pilots very soon after the last F-14 lands. The dogfight took place approximately 250 miles away from the ship. The top speed of an H-3 is 120 knots. It should have taken the helo nearly two hours to return to the ship.
Factual error: US Flight suits certainly have their share of insignia on them, including name, rank, unit and sometimes others. Often aircraft type, school and hours awards are also worn, but they don't look as much like NASCAR fire suits as the movie makes out. Even so, all extraneous insignia are removed when operating in a combat zone. They're attached with velcro for this purpose.
