The prototype BS-1 was designed by Stender as the initials indicate; the BS-1 was closely based on his earlier Akaflieg Braunschweig SB-6 Nixope, produced whilst he was still an undergraduate. Two prototypes were built by him and his three assistants in 1962. He was then a young engineering student and designed the aircraft at the request of a

While the designer was test flying of one of the prototypes in 1963 the aircraft suffered an in-flight structural failure and Stender was killed. Glasflügel then took over the project and re-engineered the design, based on their experience producing the Glasflügel H-301 Libelle. The company went on to build 18 production aircraft.

Operational history

The BS-1 was considered one of the first soaring "super ships" and was one of the most high-performing gliders of its time, the mid-1960s. Alfred Rohm of West Germany flew a BS-1 to a world speed record of in 1967. Thierry Thys of
