Hegetschweiler Moswey III
 
Heget3-01
 
Before the war and during the 1940s the best-known sailplanes to emerge from Switzerland were the Moswey range of training and competition single seaters designed by Georg Miiller arjd produced by the Hegetschweiler firm.
Like the 2A, the Moswey 3 is made of traditional plywood and fabric, though the wing span is reduced to 14.0 m (45 ft 11 in) for aerobatic training.
 
The Moswey III first flew in October 1943. In 1948 a Mk.III piloted byAlwin Kuhn took third place in the World Championships at Samedan in Switzerland, and that same year one flown by Siegbert Maurer made the first sailplane crossing of the Alps from north to south. After the war a Moswey III set the first world record for speed over a 100km triangle, and this variant captured most of the Swiss national records of early postwar years.
 
In 1950 the Mk III was succeeded by the Moswey IV.
 
Ten of the 14 Moswey IIIs built were still on the Swiss register at the beginning of 1964.
