Transcontinental and Western Airways Flight 1 (TWA 1), a Douglas DC-2, crashed into Cheat Mountain, near Uniontown, Pennsylvania, approximately 10:20 a.m. Eastern Standard Time on April 7, 1936, killing 12 of the 14 passengers and crew aboard. Flight 1 was a regularly scheduled TWA Sun Racer flight from Newark, New Jersey to Los Angeles, California with almost a dozen intermediate stops between. Approaching the flight's second stop, Pittsburgh, Pennsylvania's Allegheny County Airport, pilot Otto Ferguson lost contact with the airport's radio navigation signal, and tracked several miles in a southwestern line off course. Fearing icing conditions, he descended in an attempt to find visual landmarks for navigation. Thick fog hindered him, and his descent continued until Flight 1 hit ice-covered trees atop Cheat Mountain, about 40 miles (64 km) south of Pittsburgh on the West Virginia line and near Uniontown, Pennsylvania.
