The prototype of the Bücker Bü 131 'Jungmann' flew for the first time on 27th April, 1934. The model shown here, the Bü 131B HB-UUU, was manufactured in 1939. It does not prevent it from remaining particularly performing. It is based at Lausanne-LSGL. (Picture taken at Yverdon-LSGY on April 10, 2009.)
