Jet bombs can collide with the jet and instantly explode.

I'm pretty sure it's just the stealth fighters, but if you go in for too aggressive of a bombing run it can cause the bomb to collide with your jet instantly and kill you.  It happens when you try and drop while pulling a high g turn and burn out of the drop.  You hear the bomb doors open, or the bomb release only to explode immediately.

I expect to be able to use any weapon on the jet, and not immediately die from suicide after I press the fire button.
