Which points out a basic flaw in Axis pilot rotation: Their best pilots flew until they were killed. An Ace killed in a landing accident or an engine fire is just as dead as one killed in a dogfight.
Our best pilots were regularly rotated into training slots. Either as IP's or tactics or training on the next "hot aircraft". Tactical know-how was imparted to new pilots until our "average pilot" was much better than "their average pilot" -- plus ours were generally better equipped. That's how you win wars in an industrial age.
