Widerøe, a regional airline based in Norway, was established by Viggo Widerøe, Einar Isdahl and Arild Widerøe on 19 February 1934. The airline started off with a combination of scheduled, aerial photography and general aviation services using seaplanes. It lost its route concessions to Norwegian Air Lines in 1935 and was subsequently bought by that company, for whom it operated several minor routes. World War II hindered Widerøe from operating any flights between 1939 and 1945. After the war Widerøe started flying various seaplane routes that were too small for DNL and its successor, Scandinavian Airlines System (SAS). These routes were commonly flown using Noorduyn Norseman and de Havilland Canada Otter aircraft. During the 1960s Widerøe attempted operating Douglas DC-3s for charter fligh
