I once survived a 4-v-1 in a P-40E taking much damage and killing 3 of the 4 (making the 4th run home). Rare for me, but a really great fight that I won despite bad numbers. In the fight I got 1 flap jammed in 1 position, and the other in another. Just barely managed to finish off the last guy, or he broke off and later crashed, or something.
It made RTB home very.... "interesting" (it was an entire sector over water), especially considering it made my flying speed extremely slow.
