FV - High and the Mighty was written by Ernest K Gann. An even better book of his is "Fate is the Hunter".
Other good aviation books I can recommend to the multitude (apart from some of those already mentioned):
Flying Fury - Major J T B McCudden, VC and lots of others - best piece of advice "Don't turn back on an EFATO!"
War In A Stringbag - Charles Lamb
Winged Victory (needs mentioning again)
Penguin in the Eyrie - H Bolitho - intriguing insight into the int world of Coastal Command in WW2
And last - if you can find it - the English Translation of a Czech novel about Czech aircrew in Bomber and Coastal Commands - Riders in the Sky by Filip Jansky. Once read never forgotten.
