Going Solo was a biography of his time in the war, not a childrens book if I recall correctly, and a good read. I like the bit when he turns up at his new squadron and is given his new Hurricane (after flying the Tiger Moth??). He asks his CO who is going to teach him to fly it and the CO says "you are, you have 6 hrs, get on with it..."
And we worry about changing from C172 to PA28
