Norwegian Armed Forces Aircraft Collection (Forsvarets flysamling Gardermoen) is a military aviation museum located at Gardermoen, north of Oslo, Norway. The founding of the Norwegian Aviation Historical Society in 1967, gave the first boost to the idea of preserving aircraft in Norway. The Collection's Heinkel He 111 and  Northrop N-3PB are among the aircraft traced, recovered and restored at the instigation of the NAHS. From the latter part of the 1970s onwards, a considerable number of historical aircraft were assembled in an old ex-Luftwaffe hangar at Gardermoen and from the mid-1980s the public were admitted to the hangar during summer. Most of the activities were - and still are - based on voluntary effort.
