- How might
be measured? Is hang glider progress being helped or slowed by the presence of
sport competition? Is progress in hang glider designing helped or slowed by the
duplicative commercial success of a particular design direction? The craft is
distinct from human social participation; what is the significance of each of
those two spheres? Did Moyes and Bennett slow the development of designing in
hang gliders by way of drawing energy into a small niche of Rogallo design? What
if no Rogallo-wing-using hang glider was allowed to be flown; then what might
happen to the dream to fly? What if a huge amount of energy was spent on
rigid wing development? Perspectives? What is important to one person may
not be important to another. Success is a fuzzy concept; significance is a fuzzy
concept. What might be a positive development to one person might be considered
a detraction to another. Each perspective can tell its story.

- As hang gliders are free-flying kite systems,
they are a proper subset of the general set of "kites" where the tether to the

provides an avenue to hang gliders. One may explore any kite system and wonder
about tweaks that would bring forward something for hang gliding.
- [Shared in group as a rough draft of a larger
essay under way; see HGH, November 13, 2007]
Local "invention" is at least true relative invention, even when in other
localities the same innovation may have occurred at an absolute earlier time.
The lack in the world of a true universal patent system goes some distance in
respecting the localized benefit local inventions that may not be absolute
universal global inventions. For all we know, everything on earth is already
known well in some other planet in some other galaxy; a national patent office
does not hold off granting patents for lack of seeing other galaxy matters.
Similarly, local communities very often celebrate their local flying-machine
"inventor" with great energy; the joy of having a local "inventor" can well
bless a community; that community grows in strength and has a face to the world.
But when a local "inventor" jumps into the world community and rashly claims
absolute universal invention on a matter that had clearly been invented and used
prior to his or her local event, then an important challenge is presented that
could be handled by reasonable people with effort. A guard of "Maybe
someone else had already invented the same matter." might serve to keep the
peace as one enters a global arena. Then, after full disclosure of the
world's art set with its timeline and localizations, one might venture to claim
global universal absolute invention rights on something. Or, a pause of,
"Our local guy or gal wowed us in our community; we are stepping out into the
world community now and wonder politely if anyone else in human world history
came up with what we found." Then upon sufficient research, it might turn
out that the local "inventor" was also a global inventor, or not.
Another dimension to local "invention" relative to global
matters is the degree of isolation from the toys and arts and objects from the
world community. If the isolation is breeched by toys, models, images, school
exercises, used technology, then such makes it even more important to discern
even what will constitute local invention.
That the Rogallo wing tacitly was present in Australia
through Mike Burns, through technical literature, through public media, through
toy kites, through TV, through radio, through aeromodelling, through at least
one photograph, then we would respect JD only if we took a very long pause over
all of his influences...even beyond his memory...to discern even his "local
invention" quotient. This is only in focus because one local guy GH Kiwi has
been dead set to claim many global invention things about JD's ski kite in a
most impolite intrusion in the global community without having done a full
research of the global community's art nor of the intrusions of world art into
the fabric that surrounded the local JD as he grew and then made a manned kite.
The lack of pause and politeness of the GH guy ...until a comprehensive look at
the world's art and timeline as he tries to grab loudly and rashly pinnacle
stations for JD.....has been a trying moment for some people who care about the
integrity of the history of hang gliding and aviation in general. The impolite
tactic has been to set JD on the king point of about 13 meta-dimensions of
aviation and hang gliding; and then, in effect, brashly said: "Knock him off the
paramount places, if you can, you Lying World!" GH rashly
called into question the souls, the morality, the worthiness, the honesty, etc.
of many people as those people began to indicate how JD cannot reasonably
validly hold the 13 meta-dimension king stations or chair. Those workers in the
field had never met such a negative tactic in hang gliding circles; it took them
by surprise as they at first welcome GH with the assumption that he was well
meaning and probably had common decencies operating; but the surprise came as
one by one people were publicly slammed as liars, cheats, no-accounts,
unworthies, criminals, Hitlerian, worse than the worse, etc. GH admitted being
proud of abusing polite working groups just to get his JD known. GH admitted
that after working for over a year with the hang gliding groups, he had not
learned even one thing that would alter any of his positions about his favorite
guy JD. Not one thing from a host of sincere long-term veterans in hang gliding!
The challenge is that GH's position is broadcasted now with the Internet speed.
He pushed so hard that his "wins" for the local nuances leaked into the FAI
which was not careful enough to distinguish relative local invention from global
world invention for a diploma at the world level must be seen as with many
errors, hopefully to be amended some day by clear thinking and caring Aussies
and FAI workers.
November 13, 2007:
Preliminary Meditative Scenarios Invited""
Up on HGH group and then deleted for further
work; those members who receive e-mail or digest would get a copy, but the item
would not stick; only those active will be possible current workers on the item.
Is there a copy of the provisional patent
application by JD that can be placed on the table for discussion? What exactly
was he claiming in his application, if anything? Until such application is
on the table for critical analysis, perhaps we can play a bit with various
scenarios that might possibly apply.
Here is a
Scenario One: " I, (put
in your own name as you try to get into JD's shoes or skis),
in the spring of 1963 and in the fall of 1963, of MyCity, MyNation,
realize that others have built hang gliders for a hundred years--if not more,
that others have already used the Rogallo wing in very many stiffened-and-framed
formats for hang gliders and aircraft vehicles of several sorts, that others
have used weight-shift control of the pilot's mass relative to the attitudes of
the Paresev-1B-like stiffened Rogallo wing, that others have used the
Spratt-gifted control-wing technology with a triangle control airframe (or U or
W or V, cabled or strutted or mixed) part and format over land and water (I even
used the Spratt control-wing technology with my gyrocopter!), that others have
already foot-launched and foot-landed a Rogallo-wing stiffened for sport use,
that others have used the Rogallo-wing stiffened and flown over pontoons for
water landing, that others have made modern Rogallo-winged stiffened wings for
sport purposes, that others had already slope soared with such hang gliders,
that others' hang gliders using a similar wing as I am making did use battens
and shaped Dacron scalloped trailing edged sail before I will be using such,
etc., but with all of that prior art, I have something--ornamental design
only, not mechanical innovation--that I claim to be globally
innovative as I will describe now with a diagram: [precise cable lengths,
precisely situated Spratt control bar, precisely situated seat coming down from
a Spratt hang point from the wing above, precisely situated tow-point structure]
for a claim of ornamental design (as I realize that all the mechanical functions
and processes have been priorly invented by others before me). Such precise
dimensions provide a precise appearance that I ornamentally claim as new and
worthy of protection; I realize if someone substantially alters the
appearance to gain a new appearance, then I will have no claim over their
new appearances. Indeed new appearances probably will be using the same
prior mechanical arts that make kites and hang gliders useful craft just as I
have used those prior arts invented by former people around the world.
[When Moyes or Bennett would change the appearance of their own designs while
using inventions in place prior to my kite-glider, then they would posit new and
different appearances and perhaps some new mechanical innovations as well. Since
I chose not to go to term with an application for an ornamental design in my
country, it must be considered fair that Bill Bennett applied for a U. S.
ornamental design patent that did get issued to him; and I take notice that Bill
Bennett did not apply for a mechanical process patent as he probably realized by
then, as I do now, that all of the mechanical processes involved in our made
objects were already invented by others; and so I do not use the term "steal" as
my "friend" did against Bill Bennett for the getting of a U.S. Patent for
the ornamental design that had the pontoon lines and the tow-ring mount line; I
do not even remember precisely whether my lines were as I see in Bill Bennett's
design patent.] In any case, I will ask the FAI and HGFA to amend
the diploma so that global mechanical innovation is not nuanced, and that other
errors in the diploma are corrected. I accept that I am a local
innovator--I was first in my neighborhood--and am proud of that! I now realize
more factually that others had furthered hang gliders in many ways before my
doings, that Barry Palmer had 7 to 8 hang gliders that explored four systems of
control including the fundamental mechanics involved in my doings, that the
Paresev 1B wing can be seen as the template forerunner of what I finally came up
with after over a year of tweaking my kite's wing, that various flying wing
technologies and hang gliders and NASA high aspect ratio models and studied
devices reach into making modern wings beyond the Standard Rogallo that I ended
up making an instance of (as did Palmer). I realize now after reflection and
study that I should not have permitted my associate to over-claim me in several
ways; for this I am sorry and will change course." THE ABOVE IS A ROUGH
DRAFT THAT is meant only for meditation by any anyone trying to get into JD's
shoes or skis in order to face the challenges of big meta-claims made by GH for
JD's case. Send in
other scenarios or tweaks to the above. Eventually, some clear robust expression
may well fit where all parties in hang glider history are merited in balance;
and then will GH take off the Net inapplicable meta-claims that do detract from
the prior merits of so many people?

- Some concepts and issues:
- How the social context is probably paramount
over hardware. The BEING THERE with enthusiasm forms movements. The
enthusiasm of Bill Bennett and of Bill Moyes
with his son Steve can be seen a huge factor for accelerations in sport
competing. His way of using a standard Rogallo
kite-hang glider under tow in shows and exhibits added impulse to part of the
context of world hang gliding. Add that enthusiasm and way to the flow of
enthusiastic multi-faceted activity of the Southern California flock (imbued
with synergies from Palmer influences, Rogallo-NASA influences, MacCready, etc.,
with its impacts on markets and a boon we got.
- Distinguish wing from fuselage solutions.
- Distinguish wing from additions to wing.
- "Dr" Francis Rogallo (A.B., Stanford
University, 1932; M.S. in aeronautical engineering (one of the first in the
nation on such major) in 1935, and honorary doctorates from many institutions
and people in the hang gliding community, thus "Dr." is applied in those
communities that so accept him).
- Distinguish ornamental design patent from
process/utility/machine function patents.
- Appreciation due diligence to effect
appreciation of claims
- Appreciation of consultations that lead to
material practical explication of claims
- Recognizing generosity, even to a fault
- Appreciating that "Rogallo wing" refers to
Gertrude as well as Francis
- "modern" fuzziness
- For those "skilled in the arts"
(attending aircraft building), thousands of ready solutions are available that
cannot thus be reinvented ...to fit particular uses of wings.
- How much has the
Espenlaub-Spratt-Water-Ski triangular and U and W control bars affected hang
glider progress? How Barry Palmer did amont his 7 to 8 hang gliders include the
triangle control frame, once at his back and then in his front for controlling
the attitude of the hang glider wing...
- What are safer and better and
different alternatives? Alternatives to the Espenlaub-Spratt-Water-Ski Triangle
[AtoESWST] for hang gliders? Consider the One-Up (tm)
for an innovative way to pilot a hang glider.
- Exactly what were all of the variants
of the Aerostructures 1962 kite in 1962 and first part of 1963?
- Access to prior art without having to
laterally refer to secondary and tertiary explorations is professionally
an orderly way of moving ahead for manufacturing and legal respects. A
mechanical and ornamental design interloper does not get the rights of priors.
However, the activity of intermediaries do format the activity load of
historical events; credit can be given for Dickenson doings, sharing, and
being there with a Rogallo wing of Paresev 1B priority (both in appearance
and machine process) atop a water-ski-trapeze; his being there to
introduce the Bills was socially important. Without being there for
others we get nothing; the hardware is secondary to being there flying
- Take a powered early monoplane having wheels at
the two ends of the base of a triangular landing gear; drop the engine, hang the
pilot below the wing and use the Spratt control wing control system, and presto:
- Instruments for hang gliding...at home, crew,
- The costs of hang gliding and paragliding....
- The green factor of one's hang gliding system?
- Styles, modes, niche activity...
- It is as yet under-appreciated about Barry
Palmer FOUR control methods materialized: simple parallel bars with pendulum
control wing manner, combine parallel bar with rear triangular bar as limiter
during exploration of lift moments with pendulum weight shifting of hips and leg
masses, frontal U and triangle control frame with the base bar as central at
chest as he found center of lift, and then he tried the hanging seat.
Spratt is present; Rogallo is present, NASA is present, the bag of available
solutions is present; this guy raced ahead. He waited for nobody; he went head
to trike the Rogallo wing stiffened just so for his successes with several
versions of trikes.

The skybow is a case of
taking a principle to the extreme. It consists of nothing more than a length of
ribbon up to 1000 ft long, tethered to the ground at each end. Swivels at each
end, and at points along its length, allow it to rotate (faster in the middle)
and so generate lift by the Magnus effect, causing it to arch into the sky. As
it spins, it makes a weird whining sound. The inventors, Jim Mallos and Tony
Frame put together a fascinating
web page, which includes a recording of its sound.
