By the time the aircraft was over the Cheyenne range, the ceiling was 900 feet with sleet. The aircraft was cleared to descend from FL140 to FL080. Severe turbulence as then encountered, including severe icing. The Curtiss C-46 lost control on approach and crashed just 2,5 miles short of the airport.
