Not a best move, but fun. Requires that you are about 1K maybe 2K up, in a P40, facing a mounten. Do a loop or two till everyone is nice and slow. Get the bad guy on your six, point nose down, and pretend you are going to run. This works best with a 190, 109, LA7, anything with good excel. So, nose down for a couple of seconds (if you can reach 300mps thats good), drop flaps, and spiral back up. Don't forget to look behind as the bad guy flies intot he mountain with WEP on, muahahahahaah.
