I'm guessing the server gets confused sometimes, what with 50 players all shooting and flying and hacking and whatnot, the server likely seldom gets restarted to clean up anything leftover in memory. Hence: it runs funny.

The problem with high altitude bombing, is that with a small amount of coordination, two players can literally make it impossible for the opposing team to get a vehicle out at all. It's a form of griefing.
I have, and will take down my own team's bomber if they're doing this. It's borderline cheating.
