During World War II, Windisch was a captain in the German army’s mountain troops, serving in Russia.
He won the Bavarian championship in 1949 using the new style and the new position was adopted by other skiers who realized it improved aerodynamics.
Scientific tests made in a wind tunnel in Switzerland proved the arms-down style was better than the then-current Kongsberger technique.
The technique was the standard form used by elite jumpers until the introduction of the V-style in 1985 by Jan Boklöv of Sweden.
Windisch was a member of the German Olympic team in both ski jumping and Nordic combined for the 1952 Games in Oslo, Norway, but he again dislocated his shoulder and was dropped out of the competition.
