Northwest Orient Airlines Flight 6231 was the fatal crash of a Boeing 727 on December 1, 1974 in Harriman State Park near Stony Point, New York. The Northwest Airlines 727 had been chartered to pick up the Baltimore Colts football team in Buffalo, New York. All three crew members on board died when the aircraft struck the ground following a stall and rapid descent caused by the crew's reaction to erroneous airspeed readings caused by atmospheric icing. The icing occurred due to failure to turn on the pitot tube heating at the start of the flight.
