To run it?
It's not computer generated.
Didn't you notice the post-war engines on the Heinkel? Didn't you notice the mixed variants of spitfires (spit9s? Twin deep coolers under the wings). It's mostly footage re-enacting something with post-war planes, like the BOB historical society does, but on film.
Only thing "generated" are the fake-looking explosions, the gunfire/tracers/hitsprites, and some of the scenes where the planes nearly hit each other are composited from different scenes.
