I've flown it a few times with no real problems.  Last night though, I out-ran a couple of them in a 262 with no real problems, that was a bit of a suprise... correct though?  Just wondering.  Further... at least twice I had 163's zoom past me, pull up and suddenly pop!  (Kinda funny really... ZOOM....BOOOM!!) Felt sorry for the poor pilots.  
.....is there a bug or what?
P.S.  On both occasions the 163's appeared to have safely pulled out of thier dive and were well on thier way back up before exploding... near verticle.
