Transcontinental and Western Airways Flight 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. When the plane crashed it was aiming in a northern flight direction indicating that the pilot finally realized he had tracked south of his flightplan and may have been trying to correct it.

The Douglas DC-2 is a 14-passenger, twin-engined airliner that was produced by the American company Douglas Aircraft Company starting in 1934. It competed with the Boeing 247. In 1935, Douglas produced a larger version called the DC-3, which became one of the most successful aircraft in history.
