By serendipity we have two fully separate stories. They both involve a flight system named "Gypsy."  One by Ray Hook in 1975c and a very different project by Alex Morillo involving the joined-wing concept.

Alex Morillo    
and his joined-wing project

PS:  Julian Wolkovitch many times visited my 1971 office. He brought drawings and models and his hopes for funding. He lived in my home town of Culver City, California.

PPS: Morillo's drawing style reminds me of Bob Lovejoy's drawings. Bob developed the Quicksilver hang glider and explored High Tailer and before that a tail-less biplane.  The ultralight version of the Quicksilver reached super following.

No less than Sir George Cayley noted data bout Jakob Degan's raising himself in the air. [Though Cayley had less than full information about Degan's details and may have had some false assumptions about just what Degan may have achieved.]  The raising may have been with ornithopting. James Means put his own name behind publishing Cayley's note about Degan's flight. .Degan was a watchmaker in Vienna, Austria. The publication Nicholson's Journal in its October 1809 issue [computed by Means publishing of Cayley's "last month" in November 1809 issue of the same journal] noted Jakob Degan's story enough to pointedly catch the attention of the thoughtful and flight-concerned experienced George Cayley.   So, we seek more information about Jakob Degan's aerial success. And raising himself in the air before others have done so, and so such in a way that would catch Cayley's attention, must count as something big in the modern history of flight; it would be deeply unfair to compare Degan's success to what would occur 100 years later. But it appears that Degan flight helped to turn heads....and speed Cayley's bringing together Cayley memoranda into the light  sooner than later.  So, special double hats off to Degan for his own doings, his getting some published note, and then to turn the Cayley head and hand so that we got the Cayley notes. And nearly simultaneously we the the treatise by Walker. The three of them seem to have cinched the opening of modern winged aircraft. The confidence of Cayley and Walker finally was valid ...and confirmed by the flowering of modern aviation that developed from the seeds of Leonardo da Vinci and into the reality of the valid steps by Degan, Cayley, and Walker. The stream or trunk of valid directions and working principles were then visited by others throughout the 1800s and 1900s giving gliding, soaring, and powered flying its vast harvest.  The starts are so very important; they gave us platform for a thousand and more furtherings.  Even today, we continue to innovate upon their shoulders.

• The triangle control frame, the A-frame, cable-stayed with pendulumed pilot was on a true battened-sailed hang glider already in Breslau territory in 1908; the technology of tension-held pilot was world-broadcasted in the 1910 Popular Mechanics plans for a very light powered craft; the cable-stayed triangle control frame with pendulumed pilot beneath hang glider wing was further instructed by Spratt; the very wing for hang glider flexible wing in 1961 was Rogallo Wing stiffenened in four-boom foldable fashion made by crew under Charles Richards; the same technology was echoed in Mike Burns aqua-glider; James Hobson in 1961-2 had the hang glider at Dockweiler (Jim was director of Lawrence Welk TV shows: he predated Miller). Also, see how Rogallo saw in 1972 how clearly he understood the difference between ornamental design product tweaking and fundamental mechanical invention.  The John Dickenson (JD) episode was a tinkerer ornamentally finding what had certainly already been achieved by priors. You have been given a off-story by GH and you simply parrot the story. The invention of the flexible-wing hang glider actually occurred in the 1800s and very sturdily tweaked in 1906, 1908, and beyond...all before Sept. 1963.   It is a deep injustice for you to forward the GH-JD  claim at global mechanical invention when such is simply not fact. JD had his own-relative-to-self tweaking of prior mechanical invention to have a tow kite that was absolutely already priorly understood mechanically in every aspect in whole and in part ...and had been built and flown in model and manned-use size.  The "Rogallo Wing" as yet in your 2008 notes is misunderstood; the Rogallo Wing in 1960 and before was understood as the fully-flexible wing; when an item holding the Rogallo Wing in stiffening format, the word in 1960, 1961...was "paraglider" ... a term morphing later to a Jalbert parafoiled  limp hang glider. Yet in the maturity of use of the stiffened paraglider (1960-64 term)...the 1960-64 wing used in hang gliders by NASA in later 60s used a carry-over terming of Rogallo wing (hang glider) in honor of the stark leadership from 1948 to 1968 that Francis Rogallo gave to all levels of stiffening of the limp Rogallo Wing...including the mechanical principle instruction of uses of the Rogallo Wing and its many stiffenings from limp to full solid.   Mike Burns had and also advertised his stiffened Rogallo Wing ...Paresev-influenced as "glider" all before the JD happening; and Mike Burns utilized the mechanical factual structural system of hung pilot mass behind what was starkly instructed in 1908 (and before and after in 1929 and 1929 and during 1950s).  JD ...in stark contrast to your parroting the GH-love-feast-over-JD, did not have any global mechanical invention for hang gliding; his sporting social presence with his towed kiting was important, not for any global mechanical invention.  Francis Rogallo was not an expert in 1964 on distinguishing between ornamental product innovation and mechanical principle invention; you have taken advantage of his generosity while not coming up to speed on the distinctions of types of invention; personal local private-to-self-inventing cannot stand as global-credit-mechanical invention when being fair to the innovators in aviation that actually gave the foundations to our current uses of their steps.   What we know today in simple hang gliders came from mechanical inventions in whole and in part before 1963. Though the drive to power occurred, notice the historical glider space prefacing and underlying the powered efforts, also.      And least we forget, Barry Palmer actually reached an echo of the 1908 mechanics ...and Palmer was before JD, yet even Palmer did not make overclaims as the GH-JD camp has done with your support which is invited to change.    JpF
   
•    Terry , the Conduit Condor at the Otto Meet was a echo-beginning of advanced flying wing hang gliders. The 1906 Weiss flying wing... and then the Horten wings and the Jensen hang gliders are just some of the advanced items that our recent-decades rehashing and tweaking use to happy experience. The Miller Conduit Condor and the Culver twist, the Frank Colver Sailwing (aka Colver Skysail) , and then the
Seedwings innovations by Bob Trampenau,  and the Roy Haggard items brought in further innovation to foundations that pre-dated 1960.  Popular use ...counting heads... does not make mechanical invention.   Counting heads in the 1970s?==look to the influence of the Kilbourne as person and plan (which plan credited appropriately NASA); Kilbourne did arrive from Bennett, but mechanically he saw fit to see NASA, but was not aware enough to know then that 1908 from Breslau's gliding club had the teachings of the mechanical cable-stayed triangle control frame in front of the the hang glider pilot who was pendulum hung for foot-launching.      JpF
 
• Both the British and the USA owe mechanical-invention respect to pre-1960 stark hang gliders and mechanical aviation inventions.  Using already-invented mechanics in whole and in part is a different matter; popularizing something already invented is a different matter.  Mistakes of credit are found throughout; there is still time to make the whole story more accurate by continued care and work.   It will probably be decades before the GH-JD-love-feast-caused over-claims on mechanical invention get clear even in the eyes and minds of those who care because of the deep GH push.    JpF
   
See Rogallo's 1972 note   at    Http://HangGliderHistory.com/     and see there also a photo of a 1908 hang glider showing the triangle control frame in front of a pendulumed hang glider pilot beneath a flexible sail that was heavily battened. Anachronistic "Rogallo hang glider???"       JpF
 
• Terry, ...to be fair to hang gliding, much more is yet to be done.    Letting it seem that someone globally invented mechanically something that was already globally mechanically invented would be a profound disservice to hang gliding.     Polite discussing the facts are invited.  Finding something interesting does not make that matter fact. Just because GH can do something does not mean that he what he wrote is fact.   Are you willing to work further on the matters?   The challenge herein is friendly in my vision. Warm fuzzy feelings for JD should not keep us from finding and crediting mechanical gifters as distinct from ornamental appearance tweakings in particular versions and products.

  
    Even Santos Dumont tensionally hung his body beneath the wing Demoiselle at the appropriate point (though he chose to short-hang from the frame); the mechanics were far under his belt, he felt confident to put a motor on the glider and publish full plans freely in Popular Mechanics for all the world.   Try 1910, actually try 1907 for his use of tension-seated pilot in his parasol craft.  Power-off: gliding.      Demoiselle:

  Look to early 1800s for pendulumed main-mass beneath flexible wing hang glider mechanics being demonstrated solidly; thus the global invention of such were set and communicated to others.  Look to early 1800s in Cayley and Walker for starters on pendulumed-controlled flexible-wing hang gliders. Go to Maxim and Pilcher for further play. And others. After Chanute's seat hung, go on through the first decade of the 1900s, go then into Espenlaub and peers, then Spratt fully instructing the mechanics involved; then users of the mechanics in the rotary wing; then all of Rogallo 1948-1962 related flying items and communications; spot Palmer's echo which was solid; add Mike Burns' full expression and NASA-Rogallo relating. Nothing mechanically new left that could be found mechanically globally new in the JD tow-kite-glider; locally new to JD: yes, but surely not globally mechanically new.   So a GH fell in love with JD and finally could see nothing but an argument toward clear overclaiming that used one kind of credit to try to win unfairly credit for other matters. Yes, JD made a kite apparently new to JD; the joy of making and using and extending is all positive; what becomes harshly unsupportable is using a positive in one space to grab what is unearned in another space.  Are you willing to work to help clear the texts?             JpF

And Pilcher's Hawk of 1897 and the 750 ft glide   

The initial Reissner Design of 1912: What does the design have to do with gliders? What was evidently showing up in the first ten years of the 1900s? What was mechanically fully known about gliding and then powering? Pendulumed mass for control of gliding was instructed in the first 10 years of 1800s; explore Cayley and Walker comprehensively. Mid-1800s, explore known mechanicals of Wenham.  Upon powering and wanting higher speed, the at-least-by-1908 hang glider triangle control frame or A-frame with pendulumed pilot on a stiffened cloth sailed wing--mechanically as we know it today--was used later broadly in all decades of 1900s as a landing gear holder while keeping its founding twin queen-post bracing in flying wires and struts. The later occurrences in 1920s of the triangle control frame in hang gliders strutted and in 1929 forward in kites and hang gliders cable-stayed and strutted were founded on actual uses prior to 1910. The flexible-wing glider and hang glider was also pre-1910. The 1950s' uses of fully-limp "Rogallo Wing" devices ended in a strong revisiting of stiffened earlier-known mechanical principles; that strong re-visiting continued in the 1960s forward with profound careful studies of the limp and stiffened flexible wing; because of Francis Rogallo's leadership and understanding of the underlying fully flexible Rogallo Wing, many kept his name attached to the renaissance that held many revisits to already known arts.

Learn to fly hang gliders ~ Join the Torrey Hawks

Join the Torrey Hawks

• Cost - FREE    
• Simple as calling Bob at  (858) 204-7499  and ...a bit more..  

Torrey Pines Gliderport (TPG) is for the public to use their sailplanes, primary gliders, RC scale gliders (unmanned), non-scale RC gliders (unmanned), governable parachutes of low and large size (paragliders), and hang gliders.  Clubs are free to form themselves and join in the cooperative use of the public park.   One of the hang glider clubs is Torrey Hawks which is an official chapter of the USHPA.    Please send to Editor@UpperWindpower.com notes about any motor-less aircraft club you form that has an interest in using the public Torrey Pines Gliderport.

Someone is thinking of forming a Torrey Vintage Hang Glider Club for pre-1950 hang gliders. Bring on a tweaked 1908 hang glider (it had the very cable-stayed triangle control frame or A-frame on a battened sail hang glider  that is so very common on many types of hang gliders and ultralights today).    Bring out the three-axis 1940s' Jensen biplane hang glider.  In composites, bring out a tweaked  (for adequate control) Otto Lilienthal foldable monolayer and also a double decker hang glider. Join in to make and fly a modernized control-tweaked Pilcher look-alike hang glider. And more.

Another budding group is dreaming of forming a club dedicated to rigid-wing hang gliders for people who no longer have the use of their feet or legs. 

Another coming club that aims to use Torrey Pines Gliderport will emphasize pilot-in-wing (PIW) foot-launchable and foot-landable sailplane flying;  They will be using advanced nanotech enhanced composite construction. These will not be hang gliders but will be carriable in a personal car. They are looking for a name. One name brought up is Torrey Swallows  on a play of the  small bird and also a play on the wing swallowing the pilot. Until the Torrey Swallows get fully formed, they may use Lift space for communicating progress and notes.    Send appropriate notes to Editor@UpperWindpower.com  or easily enter data online at:        Use click=> Enter Data  +

Another potential club would hold novice hang glider pilots who will pick the very conservative weather conditions for specific hours of flight; perhaps their name will be Novice Hang Gliders Association of San Diego (NHGASD); they will want representation on the Soaring Council.  There are times and conditions at Torrey Pines Gliderport when novice hang glider pilots may have safe flights. 

A concessionaire is approved by the City of San Diego; competing concessionaire arrive occasionally. The park must remain open to the public regardless of membership in any private citizen club or association. A Soaring Council is a private advisory group that aims to keep the City from having a headache about the flight operations occurring at the public park.

[Editorial: Have times at TGP  when Novice hang gliders can fly under instructor watch.  Correct online presence that clearly favors governable parachutes by severe neglect over more accurate views on hang gliding.  The FAQ set of questions and answers exhibit a severe imbalance to the detriment of hang gliding and in favor of the governable parachutes (GPs or PGs).  The deep history of Torrey Pines deserves strong support of gliders, primary gliders, sailplanes, hang gliders, foot-launch pilot-in-wing sailplanes. TPG is a national and state and city treasure.  JpF]

In numbers, in pilot-head count,
do limp governable gliding parachutes out-number other forms of gliding, and why?  Will pilot communities want to split the USHPA to two orgs?  Will the Soaring Society of America (SSA) finally incorporate and warmly embrace the foot-launch sailplane--some of which are stiffened-sailed hang gliders?  SSA in 1971 made brotherly moves to be sure a bifurcation occurred of hang gliders away from SSA; that decision might be revisited with a different outcome.   When does a community want THEIR OWN org? What causes cousins to form distinct orgs?
