Keith Boles was certain he wanted to join the air force when the Second World War broke out, and it wasn’t long before he was a flying instructor. Evacuated from Singapore when the Japanese invaded, Boles eventually found himself in the United Kingdom, with an Advanced Flying Unit. A transfer to operations with Bomber Command saw him piloting de Havilland Mosquito bombers and being trained in the use of the top secret Oboe targeting system. Being part of a pathfinder unit was, he says, the safest job in Bomber Command and he came through his service unscathed.
