From the Wikipedia article

The crash of TWA Flight 8 involved a Transcontinental & Western Air Douglas DC-2. On March 1, 1938, during a scheduled passenger flight from San Francisco to Winslow, Arizona, TWA's interstate hub, the flight encountered severe weather. The pilot radioed his intention to land in nearby Fresno. The aircraft subsequently crashed on a mountain in Yosemite National Park, and was found three months later.

Flight

The aircraft was TWA plane #327 AC-III, NC13789, a twin-engine Douglas Aircraft Corporation DC-2-112 piloted by Captain John Graves, a former Army Air Corps pilot who won some measure of fame in 1932 when he located and dropped food to a group of snowbound people in northern Arizona. Crew members on board were the co-pilot, First Officer C. W. Wallace, and stewardess Martha Mae Wilson.

Flight 8 was flying from San Francisco to Winslow, which was a hub connecting TWA's transcontinental Los Angeles-New York route. It departed San Francisco in conditions of good visibility, with a cloud ceiling between 6000 and 7000 ft, and had sufficient fuel to last until midnight. The accident report list the causes of the disaster as "a change in wind direction and a sharp increase in velocity, unknown to the pilot, together with the pilot's confusion as to his position with reference to the Fresno Radio Range station, which combined to bring about flight over mountainous terrain, ending in a crash at near his reported cruising altitude."

Disappearance

Two hours after takeoff, the flight encountered a building weather front that developed into the most severe storm on the West Coast in 64 years. As the flight neared the Tehachapi Mountains near Bakersfield, California, Captain Graves noticed ice forming on the wings. He advised air traffic controllers, who ordered him to divert to Los Angeles due to the deteriorating weather conditions. Graves replied that he planned to divert to nearby Fresno due to local weather. At 9:28 PM, he requested a weather update; this was his last transmission received by air traffic control.

Investigation and cause

Investigation

On June 13, 1938, after the discovery of the crash site of Flight 8, Daniel C. Roper, the Secretary of Commerce, named a special board to investigate the crash. As the members of the inquisitorial board made their way cross-country from Washington, D.C., the coroner ruled that the cause of death of the victims of the flight was "accidental."
