Flew A4, F8, and A3 back in the early '70s. The advancement in engine output has been astronomical since those aircraft. 1-1 thrust to weight ratio was not common till the F4 and then only in burner. Today they are 1-1 or better without using the burner and some will cruise above mach 1. The F8 would break the sound barrier in burner but drank JP in huge gulps to do it. The A4E was the most fun to fly as it was light with close to a 1-1 power ratio because of its weight. Most memorable flight was solo in an A4E in Hawaii. There were enormous cumulus build ups and flying among them was a magical experience, like flying amongst a bunch of marshmallows
Will see the movie this afternoon but hear the flying scenes are spectacular and REAL, no computer graphics.
Navy started Top Gun because they were losing F4's attacked by Mig 21's. The F4 was a high powered airplane but very high wing loading made them a dog in a traditional turning dog fight. They learned to fight the F4 using it's power in the vertical and started Top Gun to pass those lessons along to the fleet squadrons. Top Gun used A4E's without wing tanks to save weight and drag because they were so maneuverable. Trained in the F8 next door to Top Gun. Didn't get any closer than that however.
