If you guys aren't tired of arithmetic, I am wondering if any fighter
pilots have shot themselves down. Probably not, but imagine you're
flying straight and level at 1000 mph and fire a 500 mph projectile at
an enemy that's directly ahead but at a higher altitude. You miss him;
the bullet follows a parabolic path, returning to your altitude just as
you overtake it. Discounting air friction, at what angle was the bullet
fired?
(extra credit question -- how many rivets could you have installed in
the time you wasted thinking about this question?)

shooting yourself down - more physics?
