History of flight

The aircraft, a Douglas DC-3, was operating on a visual flight rules plan. It departed at 3:50 A.M. PST and last contact was made at 4:06 A.M. when the flight spoke with the Tonopah Flight Service Station. One hour later, at 5:10 A.M., the plane hit a sheer cliff face on the east side of Mount Whitney at 11,770 feet (3,558 m). The main body of the wreckage then slid down the cliff and stopped some 500 feet (152 m) back from the cliff, where it caught fire. All 32 passengers and 3 crew members were killed.

Search and rescue operation

Extensive searches from air and ground were launched after the aircraft went missing, but snow, low clouds, and mountainous terrain hampered the search. The aircraft was finally located on August 8, 1969. The delay likely had no impact on the lack of survivors, as it is thought that all on board died on impact.

Investigation

The National Transportation Safety Board launched an extensive investigation upon the location of the wreckage. Its conclusions were as follows:

The accident was caused by the deviation from the prescribed route of flight, as authorized in the company's FAA-approved operations specifications, resulting in the aircraft being operated under IFR weather conditions, in high mountainous terrain, in an area where there was a lack of radio navigation aids. The weather was also a contributing factor.
