Northern Air Cargo used to operate two Cargomasters, which were both leased from Cargomaster Corp. in the early 1980s. Shown here is N133B, which still carries small and faded Northern Air Cargo titles on the wheel bay and 'NAC' on the fin. It also still wears serial 0-90533, as a reminder of its previous military career (ex 59-0533). Sadly this rare aircraft, one of only fifteen C-133Bs built (with the clamshell rear loading doors), was scrapped at Anchorage during 2000.
