I have a theroy on how that crap happens:
as to the radiator, and rudder issue, the bullets are depleted uranium, and go through the tail and damage the radiator. And when in a HO, your plane's gravitational pull (however small) pulls all the bullets flying past you onto a collision course with your rudder.
For the losing your tail from wing pings: the wing tip is armored with 8" armor plate steel, causing ricochets which hit your tail, engine oil, and the pilot (don't ask how a plane flys with armor plate wings, I haven't gotten that far yet
).
