What Happened

The aircraft, crewed by seven airmen from Britain and Canada, dived from 8,000 feet — the cause attributed to a suspected parachute harness entangled in the controls. It crashed at Gonalston, Nottinghamshire, near Glebe Farm, with the wreckage and a large blaze scattered across the field. All seven men were killed on impact: Pilot Officer George Benjamin Sanderson, aged 31; Sergeant James Graham Middlemas of Galashiels, aged 19; Sergeant Albert Dennis Clark, aged 28; Pilot Officer Archibald Thomas Noble of High River, Alberta, aged 28; Sergeant Bernard Broe, aged 22; Flight Sergeant Dennis Wright, aged 20; and Sergeant Dereck Nicholls, aged 19. A stone memorial at Gonalston honours their names.
