'Fighter Boys' by Patrick Bishop.
Truth is I bought this as a side product from buying his 'Bomber Boys' (yet to start), which in turn I bought to 'humanise' (haven't opened it but rumours suggest it may need this) Arthur Harris' account, 'Bomber Offensive'. Which again I bought after reading the sideswipe in 'Most Secret War' (R.V. Jones) about the Carpet Bombing offensive being a by-product of the low accuracy of the UK targeting equipment...
Goes in funny directions, the research. This one is pretty awesome, and does paint a vivid picture. Would recommend it!

Oh, and the Book itself. Couple of chapters a night, got a reading scheme passed to me. Read it in a year, devotional stuff
