tiger burn, I realise that it's something of a tradition in the Private Flying Forum to be rude to Tiger Moth, but here he is closer to the reality than you are.
It's true to say that the pressures on Fighter Command in 1940 were such that some of the pilots hadn't had enough training, particularly on the front line types, but the idea of freckle faced 19 year olds jumping out of their MGs and into Spitfires with only a few hours total time in their log books is one of those BoB myths.
The heroic achievements of those pilots are no less admirable when one acknowledges that, as well as being gutsy, they were in general well trained and well led, working within a brilliantly conceived and organised integrated air defence system. That's why they won. As for the other lot: in my opinion they have been overrated by romanticising historians and all those dodgy militaria buffs who still adhere to the notion of German military superiority, mainly because they had cool looking uniforms and called each other things like Sturmbannfuehrer, which to some strange people sounds a lot hipper than "Skipper"
There are also some reflections on WW2 pilot training in Pierre Clostermann's memoirs. He was trained quite intensively even though already an experienced pilot when he joined the RAF. That was in 1942, when things were not as desperate as they had been earlier, although dawn was still some way off.
