The aircraft took off at 23:31 on April 10 to Oakington. It arrives with a quarter hour to advance on goal and was hit three times by flak. Reached again on the return flight, the Stirling is located at low altitude up to Bree in Belgium when firing light machine guns reach it in the middle and the front of the fuselage. Then the Hptm Ehle goes on the attack. The German fighter shot reach at least four wing tanks and two gunners were probably killed in a second attack. The burning device initiates a recovery before plunging to the ground and go crashing into the Bocholt-Herentals canal on the territory of Tongerlo, town of Bree.
Five men were killed and be buried at Heverlee War Cemetery after the war: the pilot Sqn / Ldr Humphrey William Albert Chesterman AFC, Sgt Ernest Tolson (observer), Sgt Leslie Ellis (radio operator / mechanic), Sgt Bernard Stanley George Bugg (gunner) and Sgt Walter "Wally" Moore (observer). A monument to the airmen is near the Keyartsmolen, Keyartstraat, Tongerlo.
