Chugalug,
They included one Buzz Beurling, who did excellent work it is rumoured! :-
He did indeed ! Google "George ("Screwball") Beurling". Very successful Canadian fighter pilot in the defence of Malta: his advice to others was: "Estimate the deflection you need - then double it !"
Worked for him, 31 kills, (DSO, DFC, DFM and Bar). Later killed in an accident, I believe.
