Narrative:
Canadian Pacific Flight 21 was a domestic flight from Vancouver (YVR) to Whitehorse (YXY) via Prince George (YXS), Fort St . John (YXJ), Fort Nelson (YYE) and Watson Lake (YQH).
At 14:42, the DC-6 "Empress of City of Buenos Aires" took off on an instrument flight plan for Prince George, via Victor 300 and Blue 22 airways.
En route, at 15:29 the crew reported to Vancouver ATC Centre that they had passed Ashcroft at 16,000 feet. They were estimating William Lake at 15:48.
At 15:38 hours, Vancouver Centre called Flight 21 and did not receive a reply. About two minutes later, three "Mayday" calls were heard by Vancouver Centre. An explosion had occurred in the left aft lavatory. Smoke trailed the aircraft and the tail separated from the fuselage. The main portion of the wreckage assumed a nose down attitude and spiralled to the left until it crashed into a wooded area.


PROBABLE CAUSE: "Explosion of a device which resulted in aerial disintegration."

Classification:
Sabotage
Tail failure
Loss of control
