The Catalina affair was an incident on June 13, 1952, when a Swedish military DC-3 flying over the Baltic Sea carrying out signals intelligence gathering operations for the Swedish National Defence Radio Establishment, disappeared east of the Isle of Gotland. Three days later, two Swedish military Catalina flying boats searched for the DC-3 north of Estonia. One of the planes was shot down by Soviet warplanes but the crew ditched near the West German freigh

ter Münsterland and were rescued. The Swedish Air Force Museum (in Swedish, Flygvapenmuseum) is located at Malmen, just outside of Linköping, Sweden. Malmen is where Baron Carl Cederström, nicknamed the "Flyer Baron" founded his flying school in 1912. Along with the Swedish Army Museum (Armémuseum) in Stockholm, and the Marinmuseum at Karlskrona, it constitutes the government agency Statens försvarshistoriska museer ("Swedish Museums of the Defence Forces")
