I've never ripped a wing off a 190 (they seem usually indestructible with respect to diving speed and g's), but I remember that, in Air Warrior (another game like AH) there was a circumstance under which you could do it. If you got into compressibility, pulled all the way back on the stick, then popped out of compressibility, you could generate momentarily huge g's that would rip the wings off. Not sure if there is any aspect like that in AH.
