Saying airborne ripped off top gun is a bit of a stretch. Top Gun is a movie about naval aviators training and having a brief skirmish at the end. Airborne is a game about flying a fighter jet at air shows around the world. The two things they have in common are the plane, which was a navy fighter at the time both were made, and that airborne has a call out for buzzing the tower. Since the game and the movie came out 10 years apart their really isn't much connection from a cashing in standpoint.
Gold wings ripped off top gun. F14 cashed in on the craze, but makes no real references that I know of.
