Sierra Pacific Airlines Flight Attendant Wing

There were at least three different Sierra Pacific Airlines. One operated out of Oakland, CA from 1965 to 1966. Another operated out of Burbank, CA from 1971 to 1972. And still another operated out of Tuscon, Arizona. The Tuscon operation started in 1976 and was still in operation in 1985. This Burbank airline started as Trans Sierra Airlines and was reorganized as Sierra Pacific Airlines. There is another one that operates out of Tuscon, AZ. and this airline was established in February 1976 as Mountainwest Aviation. It is wholly owned by the Sierra Pacific Group. We do not know which airline this wing goes with. See note attached to Siera Pacific Pilot Hat Badge.
