Question: This is probably a stupid question, but I know nothing at all about how these kind of aircrafts are flown. What exactly is the purpose of the guy sitting in the back of the plane? All they seem to do in the film is look in all directions for enemy aircrafts.
Answer: These aircraft are extremely complex; the presence of the backseater, variously known officially as the Weapon Systems Operator or Radar Intercept Officer, allows the pilot to focus on the immediate needs of flying the plane, as his backseater can take on many of the other tasks required. They serve as navigators, tacticians, bombardiers, weapons systems operators and, of course, as we see in the film, an extra set of eyes; they use their discretion in passing information to the pilot, ensuring that the pilot has only data that's important to the situation and isn't swamped by trivia. Without the distraction of having to fly the plane, they can often be better placed to coordinate between multiple planes, leading to situations where the backseater can be placed in command of the mission.
Question: Why does the air traffic controller call Maverick "Ghostrider"? Surely that isn't his call sign?
Answer: The term "Ghostrider" refers to the squadron name. There used to be a Tomcat squadron called the Ghostriders. Usually in a radio call, the squadron name is followed by a number. For instance, in the first fight where we see Cougar get into a spot of trouble with the Mig on his tail, he radios "This is Ghostrider 117 this bogey's all over me, he's got missile lock on me, do I have permission to fire?" That is normally the correct term as to who is on the radio.
Question: When Mav meets Charlie in the bar, she makes a joke about his name and then he informs her it's his call sign. And she says "Oh, you're a pilot!" Considering the fact that she is an "important" civilian adviser at Top Gun and Mav is wearing his wings, wouldn't that have been obvious?
Answer: Charlie is playing dumb because she knows Maverick is trying to chat her up - he has no idea who she is and as she says later she sees a lot of pilots in there come and go.
Question: True or False: once a missile has been fired at you it's locked on to hit you and no way that banking hard would evade an incoming missile, unless you use countermeasures of flare and or chaff?
Answer: False. Missiles are fast, but they are not as agile as most fighter jets. One of the problems the first Sidewinder missiles encountered was that the Korean MiG-15's could simply out turn them (which is explained as the purpose of Top Gun in the movie). Missiles have gotten better, but so have the planes. In close quarter combat, like shown in this movie, fighters could potentially turn away from a missile.
Question: I would like to know from a real Navy pilot if the scene is correct where Maverick's F-14 is right on Iceman's tail and he tells him to fly hard right to get out of his way. This leaves jet wash in his flight path and the jet goes down. Wouldn't a real pilot be trained to avoid this kind of danger from happening with the jet wash?
Answer: Probably not a lot of Navy fighter jocks on this site. Of course he'd be trained to avoid it, but Maverick is hyper-aggressive and is following Iceman way too closely. Had he been farther back he'd have avoided it.
Question: In many flight and pre flight scenes, Ice is shown wearing a blue collared shirt under his flight suit. Is it normal for pilots to wear street clothes under their flight suits as opposed to just an undershirt? What about pants?
Answer: After being stationed onboard an Aircraft Carrier for several years I can say your observations are correct. They should have a regulation white T under there. None of the pilots I know would wear a civilian T under their flight suit because it could mark them as an American, and it could contain chemicals that in a pure oxygen environment of the flight suit could have produced fumes.
