The 'Lippisch Wien' glider, 1929, (1932). The Lippisch Wien high-performance glider designed by Alexander Lippisch, and flown by Austrian gliding champion Squadron Leader Robert Kronfeld (1904-1948). It was one of the first sailplanes intended to exploit thermals, and set world records both for distance and altitude, and demonstrated the practicality of long distance cross country flights. Kronfeld set a record on 15 May 1929 for the first glider flight over 100 kilometres. He later became a British subject and an RAF test pilot.
