[edit] History
After serving in the German Navy in World War I, Carl Bücker moved to Sweden where he became managing director of Svenska Aero AB (SAAB). He later returned to Germany with Anders Anderson, a young designer from SAAB. "Bücker Flugzeugbau GmbH" was founded in Berlin in 1932, with the first aircraft to see production being the Bü 131 Jungmann.
Sturdy and agile, the Jungmann was selected as the primary basic trainer for the German Luftwaffe. Production licenses were granted to Switzerland, Spain, Hungary, Czechoslovakia and Japan, the last one of which built over 1,200 examples for Army and Navy Air Services (as the Kokusai Ki-86 and Kyūshū K9W respectively). In Spain, production continued at CASA until the early 1960s. The Jungmann was retained as the Spanish Air Force's primary basic trainer until 1968.
About 200 Jungmanns survive to this day, many having been fitted with modern engines.
