I agree with mosquito man. It has to be the De havlineo Mosquito! Srry abut the spelling though. When it was first created, it served as a reconnasaince aircraft, then it became a fighter, then a fighter-bomber, and before they new it the aircraft outclassed the Supermarine SpitfireVI! I say that this aircraft had to be the best of the best! But since im an American i think the second best would have too be the Northrop P-62 Black Widow.
