Enemy Coast Ahead – The Original Story of the Dambusters - Guy Gibson (epub, mobi, pdf)

“It seemed that we were the only ones fighting the war for England when you sit up there on top of a cone over a great harbour surrounded by coloured lights and smelling the flak. You feel a long way from home, you feel you want to get back, you feel you never want to go again. And when you do come back it gets you and you want to have another crack. God knows why.”
Between 1939 and 1944 Guy Gibson flew over 170 missions for the RAF. He was Squadron Leader of the famous raid to destroy German dams along the Ruhr river.
