Bader had some very good points and some very bad ones. The one thing I don't like is his assertion to his dying day that he had a mid-air with an Me 109. He was actually shot down, but no doubt his total arrogance prevented him from saying so.
Another was his 'Big Wing' tactics which Johnnie Johnson poo pooed and Sir Keith Park proved time and again was a waste of precious minutes - 20 or more minutes, leaving areas undefended. Well written up in Len Deighton's book, 'Fighter.'
Still, Bader was undoubtedly a brave man but a bloody fool at the same time as his showing off in 1931 proved. But a good leader nonetheless.
