Glasflügel BS-1 Glider 

Built and designed by Bjorn Stender, the Glasflügel BS-1 is a West German, open class glider and considered one of the first soaring sailplanes of the 1960s. Unfortunately, Stender met an untimely death in a test flight of the glider in 1963. At that time, the Glasflügel Company took over the project and produced 18 of the BS-1 gliders. Constructed entirely from fiberglass, the glider features a tail-mounted parachute.

In a Glasflugel BS-1 in 1970, glider pilot Thierry Thys soared across a 570-mile flight, the third-longest sailplane flight ever made at the time.

Our glider is #9 of the 18 produced and is on loan to the Museum from the University of Texas at Dallas’ (UTD) History of Aviation Collection. World-renowned distance soaring champion, Alvin H. Parker of Odessa, Texas, originally donated the Glasflügel BS-1 to UTD in 1972.

Why are glider wings long and thin when compared to wings on a traditional aircraft?
