This is the former SE-KAG, a NC-701 Martinet (Siebel Si204D), which Sweden's Rikets Allmänna Kartverk (Land Survey Department) took delivery of in April 1948 from the French Air Force. The aircraft crash landed into Lake Mälaren four years later in April 1952. The undercarriage did not deploy and the crew abandoned the aircraft which "landed" in the lake. It was recovered and repaired and returned to service in January 1954. The last flight was 1 June 1967 from Borlänge to Bromma and put into storage due to corroison. It was struck off charge in December 1967.
