Bücker Bü 131 / "Jungmann"

Bücker Bü 131 Jungmann oli kaksipaikkainen koulu- ja taitolentokone.
Suomessa oli vain yksi kone joka pakko-otettiin ilmavoimien palvelukseen 14.10.1939.

Koneen lentotunnit oli vain kahdeksan tuntia ja se luovutettiin takaisin omistajalle
heinäkuu 1940.  Ennen luovutusta kone peruskorjattiin valtion toimesta.

Koska kone oli ainoa suomessa,  se ei kelvannut ilmavoimien palvelu käyttöön.

Kuitenkin kone oli 1930 luvulla maailman paras koulutus ja taitolentokone.

The German Bücker Bü 131 "Jungmann" (Young man) was a 1930s basic training aircraft which was used by the Luftwaffe during World War II.

After serving in the Kaiserliche Marine in World War I, Carl Bücker moved to Sweden where he became managing director of Svenska Aero AB (Not to be confused with Svenska Aeroplan AB, SAAB). 

He later returned to Germany with Anders J Andersson, a young designer from SAAB. Bücker Flugzeugbau GmbH was founded in Berlin-Johannisthal, in 1932, 
with the first aircraft to see production being the Bü 131 Jungmann.

Bücker Flugzeugbau '​s first production type, the Bü 131A was the last biplane built in Germany. It had two open cockpits in tandem and fixed landing gear. The fuselage was steel tube, covered in fabric and metal, the wings wood and fabric. It first flew on the 80 hp (60 kW) Hirth HM60R.

In 1936, it was followed by the Bü 131B, with a 105 hp (78 kW) Hirth 504A-2.
Most wartime production for the Luftwaffe was by Aero in Prague.
