I had another idea for a script. Basically if the aircraft... preferably a jet... took too much damage there'd be a chance of a flame out and the engine would die... perhaps it if it's possible make a random chance to see if the dead engine is recoverable. I know it's possible with the a10... I've heard all manner of stories about how they get shot up and somehow manage to make it home.
Still it'd be really satisfying to fire an AA right up the pipes of a jet and watch it's engine die in a shower of fireballs.
