I have a ton of original Top Gun stories because an F-14 RIO (backseater) and I saw the original script in late 1984. At the time I was working shore duty out of the Navy recruiting district headquarters on Wilshire Blvd in Los Angeles (no longer on Wilshire. That's another story entirely). It wasn't unusual for scriptwriters to bring Navy-related work to the office to get feedback. The script totally sucked. Very unreal opening.
We put the guy in touch with the LA area PAO (Public Affairs Officer) Lt. Sandy Stairs who worked out of the Federal Building on the opposite end of Wilshire Blvd (see end credits). That led to him being referred to Top Gun at NAS Miramar in San Diego (not there anymore. Now in Fallon, NV).
My brother-in-law, an F-14 fighter puke (that's an Attack pilot's nickname for guys who flew the aluminum overcast F-14), was training in Top Gun at the time the movie was filmed. His callsign is actually seen in the movie in the classroom scene. He has stories of the cast I will not repeat here because I don't want to get sued.
The storyline of the guy turning in his wings actually happened. The PAO of NAS Miramar was an F-14 pilot I flew with off the Enterprise. He is in the movie twice (bar scene and grad ceremony) and his real name is used toward the end of the movie when an alert plane goes down on deck when they want to launch help against the bogeys.
A guy my then-girlfriend-now-wife and I used to drink and party with is in the opening scenes. The blonde LSO (Landing Safety Officer) watching planes trap holding the radio phone to his ear is that guy. I was in a packed theater opening weekend after working a Navy recruiting booth. When I saw him, I automatically screamed his name in surprise when he appeared on the screen.
Guys I trained to fly basic jets who became F-14 pilots are some of the pilots credited at the end. Fun movie. Some major flaws, but it still pops into the player now and again. The original is on Netflix right now.
We'll go see the new one once things settle down.
