Sale had been reported missing on May 13, 1943 during a trip over enemy territory in 35 Pathfinder Sqn Halifax II aircraft W7885 TL-B. He evaded capture and was reported safe in Gibraltar on August 4, 1943
On December 20, 1943, returning from a trip to Frankfurt, Germany and about to land, had a Target Indicator bomb malfunction in the bomb bay and the aircraft, Halifax III HX 328 TL-J caught fire. Sale regained altitude so that his crew could bale, which most were able to do. As he was himself about to bale, he found that his mid-upper gunner Lamb was unable to jump, as his parachute was damaged by the fire. Sale resumed control of his aircraft and managed to land safely and taxi off the runway. Sale and Lamb escaped the burning aircraft, which exploded as they ran for their lives. Both men survived to fly together again
