Norwegian Air Shuttle (NAS) was founded on 22 January 1993 to take over the regional airline services produced by Busy Bee for Braathens in Western Norway. Busy Bee, founded in 1966, was a subsidiary of Braathens that operated a fleet of Fokker 50 aircraft on charter services. This included the network of regional services between cities on the west coast of Norway operated on wet lease for the mother company. Following Busy Bee's bankruptcy in December 1992, NAS took over three leased Fokker 50 aircraft, and started operating from Bergen Airport, Flesland to Haugesund Airport, Karmøy, as well as from Bergen to Molde Airport, Årø or Kristiansund Airport, Kvernberget, and onwards to Trondheim Airport, Værnes. The company was established and owned by former Busy Bee employees and initially had a workforce of fifty. It was based in Bergen, but later established a technical base in Stavanger.
