Luenger Beta 1


The Beta 1 was designed by Hans Luenger and Josef Kohler with the intent of being the first US production fiberglass sailplane. The semi boom-and-pod fuselage was composed of two fiberglass half-shells that join top and bottom. It featured a fully-reclined pilot position, T-tail with mass-balanced elevators, fixed gear and Schempp-Hirth speed-limiting dive brakes. The Beta 1 has been donated to the National Soaring Museum.
