There a quite a few planes that you can quickly kill someone if you stand and fight because they are in shock you didnt dive away and run. P-47's (especially the D-11), 190's (especially the A-5), 51's (especially the -B) are all good for that. MOST folks, by the time they decide you are not running, and start to counter you, they are already in deeep doodoo. Of course, when you run into another guy who wants to fight no matter what the situation, your probably in trouble, but those guys are rare enough that you will usually get away with it.
