Coh! And there was me thinking it was mainly the pilots in the aircraft, the RAF tactics, radar, aircraft production, the RAF groundcrews, the WAAFs, the backroom boys, the civvies working on the Home Front etc etc that won the Battle of Britain...
Breaking News from the US of A: Spitfires and Hurricanes were invented in America and all the pilots were Brad Pitt clones. Oh and America joined the war in 1939.
