Always thought the best four books I've read are:
"The Big Show" by Pierre Closterman-French fighter pilot.
"Think Like Bird" by Alex Kimbell-Army pilot in Aden.
"Never Stop the Engine when it's Hot" by David Lee-Flying over NW frontier in India in 30's.
"The Fledgling" by Arch Whitehouse-Gunner in FE2's in WW1
