 In 1966 Canadian Domina Jalbert was granted a patent for a "multi-cell wing type aerial device" - "a wing having a flexible canopy constituting an upper skin and with a plurality of longitudinally extending ribs forming in effect a wing corresponding to an airplane wing airfoil..." "More particularly the invention contemplates the provision of a wing of rectangular or other shape having a canopy or top skin and a lower spaced apart bottom skin..." a governable gliding parachute with multi-cells and controls for glide.In 1954, Walter Neumark predicted (in an article in "Flight" magazine) a time when a glider pilot would be "able to launch himself by running over the edge of a cliff or down a slope ... whether on a rock-climbing holiday in Skye or skiing in the Alps.
