Being an aviation fanatic, i know a few facts about WWII planes since i even did a research paper on em. This is what i have to say:

My favorite plane: Stuka (good dive plane)

Best all round plane: Hurricane, then the Messerchmitt Bf109

Also give a round of applause to teh Me262 schwalbe for being the first jet in action, too bad it was too hard to control for the pilots.

you got to give it to the germans for creating such an innovative luftwaffe, but then again, the RAF did beat em alright in the battle of britain. (Im neutral on the subject since im polish )
