He signed up at 18, the year before war was declared, and five years later the Flying Officer was a flight engineer and flew with Sq-Ldr Micky Martin during the famous raid equipped with Barnes Wallace's bouncing bomb
The temporary show, which highlights the legendary exploits by 617 Squadron Bomber Command, will be opened at 11am by Barnes Wallis Jnr, eldest son of Sir Barnes Neville Wallis, designer of the revolutionary Bouncing Bomb
