I saw an F6F attacking his own base one day (don't ask, I have no clue). He didn't seem to see me in my spit, so I casually pulled up behind him and closed to about 200. The odd thing is that it seemed like slow motion and my rudder movement kept the bullets going just forward of the cockpit. Normally my rudder is very spuratic since I use a twisty and it's hard to control when you have adrenalin going.
Another time I was cruising into town with my M18 and there was a spit being chased by two greens. Without even realizing I did it, I swung the turret around popped an HE round and took his wing off, then centered the turret again. I was told seconds later about what I had just done by one of the greens, and was dumbfounded.
