At the risk of going so far o/t that a Goderator interrupts (or a wouldbe goderator with too much time on his hands)
Have you looked at the special effects of that film? I know it was late 70s early 80s, but when he pulls out of Bilyarsk, those after burned jets seem a little feeble to say the least- and do you normally use afterburners to move out of a hanger?
Also, the aerodynamics of that plane are like a brick. It wouldn't fly.
