As a child Dieter Strasilla, inspired by Otto Lilienthal, practiced gliding around Berchtesgaden and in the 1960s he began parapente experiments (also with his brother Udo in USA) in Germany and Switzerland, parachute-skiing in 1972 and later perfected a kiteskiing system using self-made paragliders and a ball-socket swivel allowing the pilot to kitesail upwind or uphill, but also to take off into the air at will, swivelling the body around to face the right way.
