Designed in 1938 by Birger Hønningstad and Viggo Widerøe as a new Norwegian-built ambulance plane. The manufacturing of the first and only aircraft was interrupted by World War II, but in 1947 it was finished. Between 1948 and 1971 It flew for several airlines. It was blown upside-down and sank while tied to to a buoy in the harbour and was further damaged during salvage and had corrosion problems.
