Détails:
A Douglas DC-3A passenger plane, operating United Air Lines Trip 1, was destroyed when it crashed into slope of Haydens Peak, WY on the Humpy Ridge. All 19 on board were killed.
Trip 1 originated in Newark, NJ at 08:00 EST, and was scheduled to terminate at Oakland, CA at 01:18 PST. Several intermediate stops were planned. The flight departed Cheyenne Airport, WY (CYS) at 18:26 MST.
Adverse weather conditions existed along the route to Salt Lake City Municipal Airport, UT (SLC). Trip 1 encountered light to moderate snow and light rime ice. About 21:00 local time, the airplane was over mountainous terrain and flew into the side of a mountain at an elevation of about 10.000 feet. The wreckage was located the following morning.

Probable Cause:

It is the opinion of the Investigating Board that the probable cause of this accident was a combination of the following three factors:
(1) Static conditions encountered in the last portion of the flight which rendered the reception of radio range signals unintelligible;
(2) The continuation of the flight into mountainous country at an altitude below the higher mountains without the aid of ground visibility or radio signals to definitely identify position;
(3) A change in the weather caused by the approach of an unpredicted cold front.
