The crew was performing a night training mission and departed Abbotsford Airport on the evening of November 9. While low visibility, pilots were unable to locate the mountainous terrain. The four engine aircraft hit the slope of a mountain located near Flora Lake, Vancouver Island, and was destroyed by impact forces. All 10 crew members were killed. SAR operations were dispatched on a huge area but no trace of the aircraft nor the crew was found. The wreckage was eventually spotted one year later.
