Just stumbled across a little thing about Malan.
From John Keegans "The Second World War", p.102
About the BoB Pilots:
"The majority were citizens; but significant numbers were Canadians, Australians, New Zealanders and South Africans (including the icy "sailor" Malan who tried to send German bombers home with a dead crew, as a warning to the rest"
I have some more on Malan, gotta go digging to find it. Anyway, given the cirkumstances (frontline interception, fighting uphill), setup (no choosing, just fight) and the armament (303's only), Malan did a hell of a job. As well as Spanking Mölders.
R.S. Tuck is another one. A dogfight with Galland ended with both loosing their wingmen and Galland darting away.
