Trans-Canada Air Lines Flight 831

Trans-Canada Air Lines Flight 831 was a flight from Montréal–Dorval Airport to Toronto International Airport on November 29, 1963. The aircraft was a four-engine Douglas DC-8-54CF airliner, registered CF-TJN. About five minutes after takeoff in poor weather, the jet crashed about 20 miles north of Montreal, near Ste-Thérèse-de-Blainville, Quebec, Canada, killing all 118 people on board: 111 passengers and 7 crew members. The crash was the deadliest in Canadian history at that time, and is, as of 2016, the third-deadliest in Canada behind Swissair Flight 111 and Arrow Air Flight 1285. It was also the worst crash of DC-8 at the time, and, as of 2016, the sixth worst.
At 6:28 P.M., the DC-8 began its takeoff roll on Dorval airport's runway 06R. The crew reported back when they reached 3,000 feet and were given clearance for a left turn. It was shortly after the clearance was given that the aircraft deviated from its expected flight path, and began a quick descent. At about 6:33 P.M. the jet struck the ground at an estimated 470–485 knots while descending at about a 55-degree angle .
