We might extend the application of [wind] power to the heights of the clouds,
by means of kites
.  ~utopian technologist John Etzler, 1833

Short-tethered free-flying kites with pilot as mooring would evolve and be called hang gliders. At times the tether was the tendons of the pilot. Then came short tethers, as exampled in Breslau in  1908 (of the Schlesischer Flugsport Club) when the cable-stayed triangle control frame was set in front of the tether-hung hang glider kite pilot to push and pull while he or she moored the wing above; we still frequently use that cable-stayed triangle control bar as in 1908 or earlier; many who re-find this triangle, hung pilot, short-tether-to-wing arrangement feel as though they have globally invented; indeed what they find is a true breakthrough for their personal life and those they then influence with their excitement.  Longer tethers and substitution of control lines for the triangle control frame permitted another version of hang glider kiting of humans: paragliding where the pilot is again the mooring point for the kite system.   Way before Spratt, Bensen, tow kiters, or Palmer, the hung pilot behind a triangle control frame (TCF) was fitted to a hang glider ...at least 54 years earlier than Palmer, 55 years before Burns and Hobson, and as much and more before the later users in Australia and North America. Variations along the way gave color and richness to the free-flying hang glider kite system. The control frame used by the hung pilot varied in size, angle form, staying manner, degree of fairing, proportion in size to the pilot, material, and use.

Did Rogallo invent the triangle control frame for hang gliders? 
No, the triangle control frame or A-frame for hang gliders was invented mechanically for foot launch hang gliders in at least the early year of 1908 in Breslau in a hang glider in an organized gliding-club setting; further use was in many places including the Spratt before the 1950s; and a firm use was in a kite-glider for homebuilders by Igor Bensen...well published in the first half of 1950s; Mike Burns SkiPlane used the A-frame in 1962.  The first decade of 1900s had a first issue of FLIGHT; in that issue was a featuring of the triangle A-frame for aviation.  The Pilcher hang glider had a firm A-frame.

There was no triangle bar Rogallo at Otto Meet of May 23, 1971. The first triangle bar Rogallo at a So. California meet was Kilbourne's at the Montgomery meet in August of 1971 (ref: Matt Colver).

 

The World Hang Gliding Association has awarded Gustave Whitehead, Tony Prentice, John Worth, Charles Richards, Barry Hill Palmer, Thomas H. Purcell, Jr., and James Hobson, Mike Burns, John Dickenson, Richard Miller, Bill Bennett, Bill Moyes, Dave Kilbourne, Richard Eipper, and Peter Brock, a combination Flex-Wing Hang Glider Gold Air Award for their showing simplicities in hang gliders using the four-boom flex-wing radiating out of standard kiting and gliding extant public-domain arts or the Rogallo-NASA-Ryan-Paresev environment using public-domain arts extant since the first decade of 1910. The Gustave Whitehead teachings that were inspired from the works of others like Otto Lilienthal, Percy Pilcher, Wenham, and others and the most simple hang glider in Breslau of 1908 that had the simple cable-stayed A-frame we use commonly today, combined with the works of these hang glider men of the Flex-Wing Hang Glider Gold Air Award, firms the impossibility of anyone fairly claiming global mechanical "invention" of the basic core hang glider that saturated the 1960s until even prior arts in flying wings saturated designs post 1974. The Gold Award by WHGA is open for the entrance of other men or women to the special award as data justifies; please send in flex-wing hang glider historical data to the FlexWingHangGliderGoldAirAward@WorldHan ... iation.org for processing and possible adding people to the award. The public-domain art extant in 1961 was super simple to copy and make into one's own tinkered wing; the ancients could have had the flex-wing four-boom hang glider thousands of years ago for successful flight as did the men of the this WHGA Flex-Wing Hang Glider Gold Air Award. One can trace the mechanics of Hobson's or Eipper's four-boom flex-wing hang glider right into the first decade of 1900s. The minor tweaks of ornamental appearance for tweaked site and use missions remain part of the story of the flex-wing hang glider. 

Unfortunately one person who came late in the game has been being pushed into an untenable claim at mechanical global invention of that which belonged to the public already; that person is listed in the award despite the infamous untenable claim that was unfortunately rubber stamped by some orgs who exercised a low-bar scrutiny over their award text to the injury of others and to hang gliding history. It can be traced how one person bullied the untenable claim along with other untenable claims. Differently, the WHGA has this Flex-Wing Hang Glider Gold Air Award that will be open to historical findings about the flex-wing hang glider, perhaps battened. Enjoy the history of each awardee's personal story and adventure. See the emptiness of the hoax, but see the joy of making and flying. The FAI, GH, and JD should know that they will probably be forgiven by the hang gliding community for the rash unsound flattening of the otherwise rich history of the public-domain flex-wing hang glider arts, when they recant and rewrite their untenable texts for some fresh version with open and fair apologies. The great sport of hang gliding has a big joyous heart and it seems to recognize how huge is the excitement that many have about hang gliding; when someone get so excited that wish to claim what belongs to another, then such matter will be brought to light by those who care about the face of hang gliding; there is no need to flatten a giant great scene into a one-point untenable. 

Let us know if the WHGA is to add other names to the flex-wing flow fit for the Flex-Wing Hang Glider Gold Air Award
