Canadian Pacific Air Lines Flight 108 was a domestic flight from Montreal to Baie-Comeau with a stop in Quebec City that ended in tragedy on September 9, 1949. Shortly after takeoff from Quebec City, the aircraft exploded in mid-air, killing all 23 people on board. The disaster was caused by a time bomb planted by Joseph-Albert Guay, who orchestrated the bombing to murder his wife for insurance money and to be with his mistress. Guay, along with two accomplices, was later arrested, tried, and executed. The incident remains one of Canada’s earliest and most notorious cases of aviation sabotage.
