Yes, someone else had this happen too! If you look just above this topic you will see TT's post about cheating.
Last night I was flying a b17 over 2, I had just hit all acks, tower, etc, and was coming back around for fuel tanks. I was in a pretty sharp turn to avoid TT in his "uberN1k"

, just as I was pulling up out of the turn, bang, both my elevators came off.
I didn't know what happened, because from my view TT was over 1.5k away and losing ground at the time. I'm also on a 10baseT network, so I don't think lag should be a big problem here.
TT was upset because he didn't get a kill for me, but that was because my tail came off by itself.

Is this a bug, or are the b17 elevators really this weak? I couldn't have been pulling more than 2 g's at the time.
Also, I heard none of the strain noises the game usually makes when you are about to lose a part.
