I'm currently half way through 'Nine Lives’, ISBN 0 907579 82 5, by Al Deere. If the second half is as good as the first, I'd highly recommend it. Lots of very personal stuff about the early days of Fighter Command and the travails of trying to get the system to change to do it better despite the very best efforts of people at the top who 'knew better' trying to stay with the status quo. (Sound familiar to anyone today?)
