John W. Dickenson
John Wallace Dickenson (22 January 1934 – 5 July 2023) was an Australian inventor, who was best known for helping develop liquid flow measuring devices and designing a successful hang glider configuration, for which he was awarded the Gold Air Medal, the highest award given by the Fédération Aéronautique Internationale, the world governing body for air sports, aeronautics and astronautics world records. == Ski kite == In 1963, after seeing an image of a Rogallo wing airfoil on a magazine, Dickenson set to build a water skiing kite that could be released at altitude for a glide to a safe drop in the water, thus designed and built a water skiing kite wing he called the Ski Kite.
