As told to me by a long-retired, now passed-away, RAF Lancaster pilot, there were plenty of anxious moments while waiting for the command "ready to corkscrew port/starboard". A certain tail-gunner on his crew had a stress induced stutter, and with a mix of humour and gut-wrenching fear, they awaited his command, "c-c-corkscrew p-port, g-g-...g-g-...g-go!"
Tom Bennett's book sounds brilliant!
