The 262 had a 5:1 kill ratio and only 200 saw combat. Over 1400 were built good thing the Germans could not train pilots and fuel them. Kelly is one of my heroes, P-80 against 262 would be interesting and I bet those tests were run at Edwards after the war.
I'm guessing that number includes bombers(?) Any idea what the straight up Me 262 vs. P-51 ratio was?
