hooee... Surprise! No Canadians mentioned.
Well According to Barrett criteria I should think
Raymond Collishaw would be in TOP 10. I would place him #3.
Leader of "the Black Flight" in WWI Scoring I think 60 victories(many are not OOC). Also fought the commies after the war. In WWII he was the Allied "Desert Fox" using 1 Hurricane to fool the Germans into thinking he had 3 Squadrons of them.
