History
The airline was initially founded as Trans Sierra Airlines in 1970 by Chris Condon and Allan Silliphant with profits from their box office hit soft X and later R rated 3-D film The Stewardesses. It was renamed Sierra Pacific Airlines when the FAA granted permission to operate aircraft weighing over 12,500 lbs. in 1971. The original aircraft were eight passenger seat Cessna 402 twin prop aircraft followed by 44 passenger Convair 440 prop airliners. The aircraft were operated out of Burbank Airport in southern California (BUR, now known as Bob Hope Airport). Destinations served included Burbank (BUR), Las Vegas (LAS), Los Angeles (LAX), Fresno (FAT), Bishop (BIH), Mammoth Lakes (MMH) and San Jose (SJC). In 1973, Sierra Pacific was purchased by Mammoth Mountain Ski Area. During the winter ski season of 1975-1976, the airline was flying nonstop service from Mammoth Lakes to Los Angeles, Las Vegas and Fresno with direct, one stop service to Burbank with 50 passenger seat Convair 580 turboprops and 19 passenger seat Handley Page Jetstream turboprops. The Mammoth Mountain Ski Area subsequently sold the airline.
Sierra Pacific also flew de Havilland Canada DHC-6 Twin Otter aircraft as a scheduled intrastate State of California Public Utilities Commission airline while also having interstate CAB exemption to cross state lines. In February 1976 it became Mountain West Aviation. It is wholly owned by the Sierra Pacific Group.
Until his death in November 2014, the long-time President of Sierra Pacific was Garfield Thorsrud, the founder of Mountain West Aviation. Thorsrud was a smokejumper early in his career and later served in the CIA, including with Intermountain Aviation.

Incidents
On March 13, 1974, a film crew for Wolper Productions filming a Bell Telephone Hour special about Ice Age Neanderthal cavemen filmed at Mammoth Mountain Ski Area, was killed when a Convair 440 plane crashed into the nearby crest of the White Mountains during its climb out from Eastern Sierra Regional Airport in Bishop, California. All 36 on board were killed, including 31 Wolper crew and cast members, although David Wolper was not aboard the aircraft.
The filmed segment was recovered in the tail section wreckage and was broadcast as the television documentary Primal Man. As of July 2012, the NTSB has not been able to determine the cause of the crash. There were no indications of technical problems during takeoff, but no plausible explanation of pilot error could be given. It is one of only three uncleared NTSB cases.
