I was in an F6F-5 one night and was attacked at an alt disadvantege by three 262's. I killed one on the first pass, one on the second and the third a little while later, then killed the first guy again when he came back for more and landed all of them.
Twice, one of them just this month, I've chased a set of buffs staying just at the edge of guns range with the pilot in the rear gun position firing while they all flew into a mountainside giving me three proxies each time.
Once I was in a set of buffs, I think B-17's, still carrying my full load of bombs when I was attacked. I dove to gain speed and noticed I was diving toward an enemy airfield. I let the bombs go just to try to hit anything and got six kills on the runway.
