Purcell,Jr., Barry Hill Palmer, James Hobson, Mike Burns, Craigo, Effinger, Richards, Breslau hang gliders, Struck, Ryan Aeronautical, Francis Rogallo, Paresev program, and scores of others continued to put into public domain mechanical arts that made it silly for anyone later to claim global mechanical invention for the simple framed-sail hang glider.
