Don't bother to check for logic. There is none. But on the other hand, there are MANY really great movies that totally lack logic, so why bother?
I both like and dislike this film. I like it because the action sequences in the air are really great, you get to see a lot of dogfighting. I also like the F-16, which is a very cool plane.
But there are just too many goofs to make me really enjoy it. I guess it's not fair to wish for SOME sort of continuity, as it is hard to make a really good fighter film - but I also think there should be some sense of reason.
And I have a question: do they fly from California to the Middle East in F-16s without air refueling? I'd like to see that happening.
