1969-1972    Shown: synopsis of Tony's caption

  • Tony's  first Rogallo type was given his attention in "1969-72 and was being flown on the Southdowns."
     
  • "The strap hanging from the rear was to seat the pilot but was not used."
     
  • "Constructed from bamboo and lashed together with waxed string in much
    the same manner as the pioneer machines of the 1890's."
     
  • Control was by weight shifting.
     
  • His arms were supported by parallel bars and a horizontal cross bar for hand grip.
     
  • For major pitch changes the whole body could slide along the parallel bars. 
     
  • For fine pitch the lower body could swing forward or back.

Some commentary so far about the hang glider:

  1. It is clear that his flight was well above ground-effecting and into solid gliding.
     
  2. He was independent of Palmer influence or ski-kite influence.
     
  3. His craft seemed to live in the Standard Rogallo class (a fuzzily-defined family of Rogallos that was begun with Palmer, broadcasted by Miller, spiced by devices as the Prentice 1969, the Kiceniuk-Dickenson, the ski-kite-glider of Dickenson, the Burns-Dickenson improvement, the Moyes standard, the Bennett standard, the Kilbo Kite, the Eipper standard, the Seagull I and Seagull II, etc. The class gained members from Miller's broadcasted plans of the Bamboo Butterfly, of shared plans of Batso, of world-around shared and sold plans of the Kilbo Kite, Seagull plans.  The multiplied commercial kites put more standards into the air, but the variety came from intrepid homebuilders until the class diminished in choice and presence as safer non-standards came to be.
     
  4. Prentice in the above had both aspects of the control frame:  U-base-bar for some control and the parallel bar to explore centers of lift control. 
     
  5. Different from the Palmer where Palmer rejected the ski-kite trapeze alone, he in 1960 chose to go forward to putting the trapeze at his back to limit rear positioning while he explored centers of lift control along forward stay bars doubling for the exploratory flying. 
     
  6. So, both Palmer and Prentice had robust control frames as they were pioneering. Both Palmer and Prentice BOTH the control base bar and also the parallel bar. These two both knew slung sitting. These are just some of the reasons to believe that the trapeze-only would have (actually did already exist in ski-kites and water gliders before 1960 enough so that even Palmer was able to have a rejection deliberately of such for his first aluminum-framed hang glider. Ken's video stating he had no reasons to believe such would ever come into hang gliding had not JD used the control frame part would need only study the past before JD to see that such already existed in pre-Palmer and Palmer. The pre-Palmer were in the ski-kites though those were sloppy gliders; the part was in Spratt wing; the part was in 1921 Gottlob Espenlaub hang glider. The Palmer and Prentice having both were just intimating that it was present and easily would be wanted after a little bit more air time teasing: let's sit through this as we are now comfortable; we have BOTH, and I'll decide to just use the one like the Flat kiters did in 1960; presto done.   Palmer had the triangle base bar as a rear limiter; Prentice had the U's base bar in front for part of the control system. Both used the pioneering long parallel bars to practice; the sitting with confidence was to be after centers and moments were discovered.  Both were in their spaces pioneering the standard class of Rogallo hang gliders using WING from NASA-Rogallo sourcing as did Mike Burns of Australia for his Aerostructures Ski-Plane (spelling?) in 1962; Mike Burns was steeped in NASA material even as he deeply improved Dickenson's kite-hang glider which also joined the standard Rogallo class. The Mike Burns factor has not been well appreciated yet [EnterData  +].
     
  7. He was among the first persons to foot-launch a standard Rogallo hang glider; the count at that time was about the count of 10, as the research is still uncovering people affected by NASA, Palmer, and Miller plans: Palmer and maybe friends, then Miller and friends for sure, Jim Hobson (Jan. 2, 1962 Rogallo wing hang glider experiments in Dockweiler beach, west of El Segundo, CA, now flight park operated by Windsports)  of Lawrence Welk or Art Linkletter (reference needed; corner of Wilshire and Ocean in Santa Monica, CA.. about 1965; he visited Low & Slow office early on and showed photographs and drawings, but was reluctant for some reason related to his professional life; he was proud of his doings but also saw the explorations as somehow challenging to his status in another sphere; he was somehow intimate with the Miller play at Dockweiler beach), then Bill Moyes in 1967 or 1969 (reference to confirm his towed vs the ski-slope slide), then Dickenson parking lot crash (still to be confirmed if this free-foot-launch or release from tow for foot-landing) [EnterData  + ] "after Moyes" (per pilot); Tony Prentice.  The intrepid pilots of Utah, of far places around the world in the 60s stemming from NASA influence, Paresev hang glider influence, the WING of the Paresev both in function and ornamental design ... probably were many in number. It is believed by this editor that the pilots from the Palmer-Miller spheres of movies' and plans' influence combined with the wide media presence of the NASA and NASA-Ryan gliders and Paresev kite and hang glider netted so numerous of pilots in mid-60s that count at 1966 was far greater the zero-count of Dickenson-sphere people with the Burns-Dickenson kite-hang glider. Not until Moyes in 1967 or 1969 (reference to confirm his towed vs the ski-slope slide) was there a free foot-launch.   So, the class of standard foot-launched devices with their pilots was infinitely present compare to the zero-presence in 1966 in the Australian sphere, pending someone coming up with reports....we are open to hear.  These were the birthing scenarios of the first class of Rogallo hang gliders: the standard Rogallo that ornamentally used the WING of NASA shown in Fleep and Paresev and stiffened parawing for a sharp-angled nose for conical-wing format with elementary control framing and elementary WING format, the essence of the first class.        EnterData  +
     
  8. That the strap was there indicated knowledge of hung seating.
     
  9. The frontal control base bar was derived from resource independent of the Australian ski-kite flows.
     
  10. "The picture I saw of the Ryan Flex-wing and used to produce my first Rogallo type glider ( New Horizon Book of Flying ) published in 1963."  "As the picture was published in 1963, the machine must have been around for some time for it to have been used in such a book."  Tony Prentice.          Editor: Yes, the picture went all around the world before that book was published. The meaning of that picture ornamentally for design invention, and process-wise for machine invention makes it impossible for valid claims of invention to occur over that WING and vehicle and the function of that vehicle which includes hanging-pilot and hanging-payload hang gliding, though it could also be powered; engine-off and presto unpowered hang gliding.
