Alpine Air Express, Inc., a Delaware corporation, is engaged in the air cargo business through its wholly owned subsidiary, Alpine Aviation, Inc., a Utah corporation ("Alpine Aviation"). Alpine Aviation was organized on October 7, 1975, in the state of Utah. Alpine Aviation has been operated by the same management since 1986. Alpine Aviation is an air cargo operator, transporting mail packages and other time-sensitive cargo to more than 20 cities in the western portion of the mainland United States and in the Hawaiian Islands. Alpine Aviation began its operations in the 1970's with the intent of being a regional charter and cargo carrier. After present management acquired control in 1986, Alpine Aviation began to focus less on the charter or passenger services and more on the cargo aspects of the airline industry. Since the 1990's, Alpine Aviation has focused on hauling mail for the United States Postal Service and carrying packages for United Parcel Service because of their favorable contracts, routes and payment practices. As a result of this focus, approximately 86% of Alpine Aviation's revenues now come from the Postal Service.
