Timeline of flexible wings, parachutes, gliding parachutes, paragliders, parawings, flexible winged kites, and water-ski kites. The development and hang gliding and ultralight aviation. All links are to pdf files, this page was started on the the 9th of January 2012 in order to demonstrate the evolution of modern hang gliders, ultra-lights parachutes and paragliders. Please note, there is a great deal more material, and more timelines, to be placed on this webpage. The timeline is being created to make the wealth of material in our archives accessible and understandable. Timelines coming soon, published accounts of history up until 1976.
