"Myth 1: the Luftwaffe commander Göring was incompetent"
He was and he told lies. So that 'myth' is true.
"Myth 2: Hermann Göring ruined the German possibilities to win the battle by turning the attention against London"
Well I always thought it was Hitler who ordered the attacks on London.
"Myth 4: the twin-engined Messerschmitt Bf 110 was worthless as a fighter"
Yep that one seems true, if the 'myth' stated that it was useless as a day fighter. At night (against bombers) it did very well.
"Myth 6: the German Bf 109 pilots were absolutely superior to the RAF's fighter pilots"
Yep they were. Because they had better tactics and experience – which counts.
But the myth I had expected was that the Spitfire won the battle of Britain
"According to the Air Ministry's own figures, for every two Luftwaffe planes brought down by the Spitfires, three were shot down by Hurricanes."
