experiments with a modified wing in "HyperLite" continue.
This prototype was prepared in the workshop
We have made some small glides (ground skimming). The inflation is
even with zero wind. The glide and speed is normal for a 4.5 aspect
wing. The brakes are very soft, but quickly change the trajectory.
working on a new leading edge to get more pressure on it.
We have not been able to experience the reaction
to the reopenings.
To do this, we think of a skilled pilot testing it at a SIV center.
I think this concept has a future, especially for
mountains wings, and even for ground handling in schools (especially
for the easy inflation with light winds and less effort required

still inside the computer, but soon will come out of it!

Hi Joe and
I've now scanned all of the slides that I had of the first time my
Skysail was flown with parallel bars (you've seen the one of
me ground skimming and of Richard Miller watching me putting it
together). This was at the "water tank hill" near Vista.
I was surprised to see two shots of Richard Miller flying it. I
absolutely did not remember that he had ever flown my wing even though
we often got together with it. I think what made the difference this
time was the conversion to parallel bars. A tiny voice in the recesses
of my memory now tell me that he felt more comfortable with this new
I'm surprised that I had forgotten this occasion. Looking at the photos
I see that we all took a turn flying the wing, that day, with the new
parallel bars. My son Matt and his friend Ernest Feher also are shown in
some photos flying it.
Attached is another "classic" photo (reduced size) of the inspirational
master trying out my version of his inspiration. I believe it is Ernest
that is giving him the helpful shove.
BTW - I've now scanned my slides of the 3rd Otto Meet (Escape Country)
and the 3rd Montgomery Meet (San Diego backcountry). Sure brings back
memories of some very good times!
One proof of the fact that this was the first day with the parallel bars
is that I don't have a swing seat under the bars. We are truly hanging
by our arm pits (like the pioneers of old). These were short ground
skimming test flights, but wearing no helmets was not a wise move, even
November 5th, was the 40th anniversary of the day I started
construction of my Colver Skysail (Nov 5, 1971). Most of the work was
done in my driveway, with my cat, Linus, always wanting to be in the
middle of the action.]]
On November 9, 1980, I made my first
and only flight from Ed Levin
in Milpitas on a single-surface Seagull 10-meter copy known as a
Spectra Zodiac. At that time, I had launched from
Cuesta Ridge in San Luis Obispo 43 times; from Plowshare in the
once; from Paiute in
Owens Valley 4 times; from Coyote in Owens Valley once; from Ray
Dean’s Hill in Owens Valley 4 times; from Horseshoe Meadows in Owens
Valley once; from the cliffs at
De Oro State Park 8 times; from Plaskett Ridge in Big Sur 5 times and
Guadalupe Dunes countless times.
I caught a ride up to the high launch with a bunch of
Wings of Rogallo members. I
was superbly confident in my ability to safely self-launch so I assisted
the other pilots on the hill in the gusty 20 mph wind. As the last few
launched, it became apparent that the wind was beginning to cross from the
right. Down the ridge in that direction was a spur that protruded from the
ridge. It was obvious to me that the spur would be generating turbulence
but the others had given it a wide berth and flown away successfully – but
all had lost altitude rapidly heading straight out to the landing zone.
The driver was gone. I was alone on the mountain. I carried my glider to
launch and performed a hang check.
I was hoping that I could also get a fast flight to the landing area. Out
in front, the sky was hazy. Judging from the flights of the others, there
was no lift. The wind was gusty but coming straight in, so I assumed my
flight would be similar to the last pilot’s. I shouldered the Zodiac,
leveled the wings and brought the hang strap tight. I brought the nose
down to neutral pitch and began to run. Although the slope of the hill
rolled off steeply, I was surprised to find that on my fourth step, the
glider would not lift. After two more, at my maximum running speed and
feeling the wing beginning to pull ahead, I pushed out a bit and forced a
The launched seemed okay but at 30 feet, I hit tremendous lift. I
immediately pulled the bar to my knees to keep up my speed in case I got
dumped – and then, about half way between takeoff and the spur, I got
dumped. I had almost made it over the spur. I thought, at the moment, that
I had been sucked into the top of the rotor but in retrospect, considering
the rounded contour of the ridgetop and the strong lift at launch, it was
probably a wave eddy and I had fallen into the trough.
My glide deteriorated dramatically and the turbulence increased. The top
of the spur rose above my horizon and I immediately realized I would have
to land on it – it would be far too dangerous to try to fly close along
side it in the rough, unpredictable air. I knew it would be dicey but if I
could pull it off, I might be able to walk up to the top of the spur and
launch off the other side. But as I bled off speed to prepare to flare on
the sloping hillside, the left wing dropped and the glider rolled to the
left. I was too close to try to recover – it would only result in a faster
impact if I shifted to the right – so I threw my weight to the left, began
a slip the short distance to the ground and planted my left wingtip into
the soft hillside. The leading edge absorbed the brunt of the impact. As
the nose pivoted around, I pushed out to trap whatever cushion of air I
could capture. I hit the ground with my body flat, bouncing off the base
tube on the dirt. The nose followed through the arc without much force and
I was down.
I quickly unhooked, picked up the glider and carried it up to the ridge
road (which I assume was Monument Trail). I knew a lot of pilots would be
watching and I wanted them to know I was okay. The only damage was a bent
deflexor bolt and slightly bowed downtubes, which I straightened.
I did a hang check on the road. Everything looked and felt good. At this
point, the side of the road fell away like a cliff so the launch into
smoother but still bumpy air was a cinch. I came into the landing zone on
a low approach and made a perfect spot landing.
I wanted to recount this flight to you, Joe, because this is likely the
same location and the same type of air encountered by the paraglider who
was killed at Ed Levin. I doubt that I could have survived that flight on
a paraglider. The airframe saved my life.
It is difficult for me to imagine a greater fool than a man who would
launch a parachute into conditions that threaten that type of turbulence.
The airframe kept my airfoil flying and absorbed most of the force of
impact when I crashed. The airframe not only saved my life – but it made
the rest of my life possible. Education, marriage, children, a career… a
fruitful, rich life. So many paraglider pilots have given this up – for
I will never understand it.
Mythology of the Airframe
Frank Colver points to some
I remember in an old Low & Slow you were thinking about humans
drifting across the earth on huge thistledown-like devices. Well, this
development is not exactly that, but I thought you would find it
interesting. It may have applications for some very light flying
structures in the future.

The most seriously deluded participants of any sport are clearly the
paraglider pilots who enter thermal turbulence without any structural
support for their wing. Of this deluded segment, the most outspoken are
the British, who seem to believe that because thermal turbulence is so
gentle in their part of the world, it must be the same everywhere else.
This false conclusion appears to explain the relatively low numbers of
fatalities in their island vs. the high numbers of British deaths and
injuries in distant venues where real thermal turbulence exists.

Adjustments from July 23,
1. Time for more things is on.
2. Have not joined any further org; I kept my free life membership in WPGA
as it specially embraces that paragliders may be made with any wing of any
solidity and upholds that paragliders are gliding kites.
3. Note that "3." was not exclusive; I continue developments on
non-airframed glider devices also.
4. Did not renew.
I keep a habit of growing daily. Richard Miller, one of my flight
instructors died, author of Without Visible Means of Support, 1967.
Bruce Carmichael was one of my aerodynamics instructors, as was Irv
Culver. I have flown hang gliders and paragliders of 0-line, 1-line,
2-line, and high-multi-line. I am adjoined to each of the 67 member
activity sectors and contribute regularly into them; the Giuseppe
sector is included.
[b]ON TOPIC:[/b] Part of this single-tether thread could explore a 1000
m tether for a ladder paraglider with payload pod being a rigid flying
wing of 10 m span using RC to control ladder flight dynamics? What
advantages could there be having that 1000 m tether?
The definition of "paraglider" being used allows unpowered HTA wings of
any sort in the upper wing set or the lower-wing set.
predict that a very long single-tethered paraglider will set extreme
world records for cross-country travel with humans aboard. Controls of
the unpowered paraglider will effect attitudes in the upper wing and
attitudes in the lower resistive subassembly. The upper wing set will
be in an air stream quite different from the stream of the resistive
or payload set. Dale C. Kramer has for years been mapping out flights
using detailed weather reports. No fuel for lift. This is a proud
future for machine paraglider. Clearance for the record flights will
be specially given by airspace governance, as the long line will be
obstacle and the airspace used will be that which is frequented by
commercial aircraft. As the physics allow cross-continent paraglider
flight, it will be permitted at least once. Moderator
I attach drawings and documents illustrating these matters?

Features paraglider as a mechanical gliding-kite system with openness to

Essentially, paraglider has a tether set and a resistive set; wing alone
does not make paraglider.
The power homebuilt activity sector is open for growth from anyone. When
power is off: gliding kite = paraglider.
Is not stuck on limp-canopy solutions to "paraglider" systems. Any
rigidity or solidity may answer "paraglider" machine.
Faces more than sport: art, service, industry, commerce, hobby, science,
travel ... use of paraglider.
Tether is key, from one to many. The kite hang gliders that use one
tether to its payloaded pilot that grabs airframed wing is a paraglider
of one tether, even though language defaults such to "hang glider."
Paragliders are a proper subset of mechanical hang gliders. Paragliders
need not have humans onboard. Paragliders may be any size from tiny
(less than size of human hand) to very huge to the limits of material
science. Paragliding is the use of a paraglider in these terms.

Um, Joe, ...,that is a picture of what is called a kite. ....
[[ED: Yes, it is a gliding kite, that is what
paragliders are! Gliding kites. You got it!
Wing, tether, resistive set is kite; when in glide the gliding kite
may be called many things: gliding kite, kite (that is gliding: the
whole of it: wing, tether, resistive mooring), glider,
paraglider, .. Wing alone does not kite make. (Recall that FAI
came in late in the defining game on paraglider; FAI does not
rule the mechanics involved; they serve sport competition needs and
only part of that.) ]].

Not sure how the development has gone to date but the idea of a multi-wing
PG has interested me for some years. Higher aspect ratio can be achieved
using less rigging so it should be efficient. It should also add to the
stability helping prevent canopy collapse which would be a good safety
Spoof PhotoShop artistic images are in a couple of places on the Internet;
such is suggestive. Closer is the high jumps made with multiple-wing
stack power-kites in minor gliders. Seemingly yet to be are serious
experiments with aggregate-stability stacked
wings tethered for manned flight. The Rogallo patents featured
multiple-wing stacks; and a later Rogallo patent at the NASA paraglider
era featured a biplane paraglider drawing. Just what experiments have been
made in the modelers' world on this matter is not on the desk yet.
Aggregate stability is of high interest in the kite energy world. We
will see some sport paragliders exploring multiple winged paragliders
(gliding kites). Maybe such has occurred already. Knowing the full
picture on this realm will be most interesting. Launching, landing,
flying ... various control means. JpF
Set into gliding we get ladder or stack paraglider for the
1948 Rogallo situation.

As with most "April Fools"
there is a grain of truth on
which the joke is based. It was out of time to connect it to
an April Fool so I was not looking for such but the article is
laced with the clues. I had spoke with Bruce Goldsmith (a
leading PG designer) some time ago about stacked PG wings and
it is possible the idea filtered through him to the
perpetrators of the spoof. Your correspondence below shows
stacking is not a new concept and I have used a kite train
with trike buggy in the past. [[See the April
With higher aspect ratio the wings become more efficient and
the rigging lines are there to start with. The span can be
reduced making the wing more agile and more resistant to
collapse. Of course it takes a lot of development work to
perfect a design but despite the joke element I wonder if any
manufacturers are considering the idea?

Shane wondered about the circus in PGForum
and does not want me to be hurt.
(Shane has known me since 7th grade and has ever looked after my best).
[Post by Armadillo is not shown here.]
Shane, if that is your focus, then I answer that Armadillo is mocking me
via what might be seen--by someone not very carefully trying to follow the
conversation--as pertinent. He wants to example a psychotic in
session who does not seem to stay coherent or stay in focus on a topic.
So, he wants to have audience applause for saying "Joe is posting as a
psychotic might post." Armadillo is being part of the mob gang bang
while he simply avoids respecting the topic of discussion.
To your question to me on reason I post.
Rick Masters has been maligned and was banned from the group. Rick
understands that the group in that forum are not caring enough about
themselves or others to the extent that a culture of suicide or something
close to that runs in paragliding as paragliding is not respecting the
mechanics within the vertical zone that Rick has coined as
Paraglider Dead Man's Curve (PDMC).
Two things: I have had a habit since
1970 to back the maligned in hang gliding (easily understood as including
all of paragliding) and to lift hidden or forgotten technology, no matter
the nature of the technology. Being simply myself in that forum and
staying polite brings the reaction you see. Such all is also a fire that
has a way of bringing out creative new clear thoughts; I did not deeply
see my fetal kite self until the effort to reach these guys--such
is now a deep life-changing realization that will affect me positively the
rest of my life (I sent my friend Dave Santos a copy of the fetal kite
graphic and text of that post; he is paramount wise receiver of such
musings and he answered "wondrous musing"--and I know that
he will never forget the meditation involved the rest of his life); the
Association run only began to blossom as a result of dealing with
the narrow culture that persists in the PGForum; hence we now have
ParaGliding Unlimited in contrast to the very limited sector;
discovering just what I am about is helped by being carved to pieces;
there is ever a grain of truth even in mocking statements, however full of
error a mock might be. The contradictions in the slams cause me to look
more carefully; I have a thanksgiving for each little challenge. And I am
challenged to go beyond the aside mocking into a path of loving the
posters despite the negative rain of jabs and distractions.
Rick and I believe that the negative treatment of Brett Snellgrove in that
forum added to Brett's challenges that brought on Brett's suicide. Is
there a way to input some helpful message to some of those most in need in
the forum; there are some leading offenders? Maybe just the fetal
kite will play a role. The first responder after fetal-kite post exactly
slams with huge contradiction; he goes to "anything" when the message is
distinct and different: only when the arrangement is "gliding kite"
does "paraglider" appear. The fetal kite was said even in his
clipped quote to be not a paraglider. Such deep non-seeing
might one day be corrected inside that responder; and then he might
advance in humility for himself and find himself as having been a fetal
kite, a potential preparation for his flight interest in paragliding.
The karma system in the forum forces a
limit of about six lines of type just one post per day for one who has
negative karma. I am so limited and try to respect each poster by saying
something to their effort; my imperfect effort on that brings on some
laconic phrases that could be best understood only by those carefully
trying to make sense of the whole discussion; but, of course, a handful of
posters are simply set to be part of a mob mockery feast. Yet this thread
and its posts may well last for scores of years or more in the searchable
literature of human culture; so the radiance of the errors and possible
gems involved will also last for a very long time; researchers will find
fetal kite, gliding-kite equals paraglider, PDMC, etc. The posts will have
a life far beyond the immediate.
Will the topic thread become a mirror for the posters and perhaps
one day give posters a chance to see themselves in new light? Just to what
extent will they go to remain gang bangers and miss the good of those they
bang? The energy could be spent directly to develop the topic.
successful author in Popular Science, taught me to post just what
is positive; he helped to get the free-flight message out to the world in
a big way in early 1970s.
So, there are several dimensions to my
perseverance. The actual topic is appropriate to the stated goals of
the forum, even as many in the forum do not see the matter as such.
"Paragliders of exactly one tether" is technically included in the
forum's focus, but most will not readily see such. My seeing is a result
of a training that is extensive; I reach to post the best gems of my life
of meditation over free-flight. The PGForum has more viewers than any
other paragliding forum in the world; so the forum posts sit in the most
viewed place. So, the message is broached in the most viewed forum.
Sincere thinkers will see through the mocking and spend some assets on the
richness that :"single-tether paragliding" may bring.
There are several branches to single-tether
1. One branch of paragliding is huge and is not seen generally as
paragliding! That branch is the framed-kite hang gliders using a single
short tether; the bat shit of the PGForum; when a person finally realizes,
if they do, that the framed-kite hang gliders are framed paragliders, then
an opening will occur that might save their lives from the kind of
paraglider they are using that have no airframe and that meet the hurt of
2. Then another branch is not used yet in sport, as no one has developed
it except slightly in scientific paragliding: where below the bridle point
is one tether and the wing is controlled by radio control in various ways;
such branch is fully strange to the PGForum, but the message now is there
for the careful; that branch has a potential big effect in aviation;
perhaps someone will do scientific papers to advance that branch, but at
least I put the core of that branch in the most-viewed sport arena forum.
Yet the topic is closer to their doings than they know. The "cage"
paraglider system is a start toward this branch; one poster saw such and I
responded positively; the Cage has one tether below a frame at the bridle
point; so such is a start. Getting the message of this branch out into the
most-viewed forum is no little feat, but one sure to bring on the
disruptive mocking that one sees.
3. Then the third branch has to do with the vast potential of extant kite
technology folding over into paragliding for a huge untapped aviation
sector that will have a sport following some day. In this third branch are
"any kite system" modified to have a falling anchor to result in a gliding
kite, thus paraglider. The "any kite" is cause for this branch, as huge
multi-winged complexes can be kites; and such can be with a falling
mooring to result in gliding kite, thus paraglider. This branch is little
known. The tension of the posting has helped me uncover historical
foundations toward what I have known in sketch and brief since 1970. A
gliding kite may also be soared in several ways. Such soaring sustains
flight for a longer time. The practical and sport implications of this
branch could grow to be huge in sport and industry. In kite energy we have
had a small club of about 10 or so persons that have been advancing
soaring gliding-kite systems (thus paragliders). Our attention on this
tech is not at all in the attention of the sport paragliders of the
PGForum and so is easily seen as "not what we do". I understand that
presenting tease toward such matter is inviting the label of "troll".
Partly I am following the wisdom of one of
the world's greatest aeronautical engineers: Dr. Paul MacCready. He
opined that it is not important who came up with a gem idea, but that the
gem idea be found, shared, savored, and made present in builds; I
paraphrase. I am learning to go down in flames for the sake of the idea;
it is OK to be personally nothing, if such lets an idea be present for the
sincere to consider. And just maybe the insincere will have the idea in
his garden subconscious that will play one day to form some
new growth. Forget the messenger, but remember the message.
How do you want to be remembered?
It makes no difference to me. The ideas and accomplishments may
deserve remembrance, but not who did them.
=> The fetal kite will not easily be erased from the consciousness
=> The "gliding-kite is paraglider"
holds power to bring on huge changes in aviation.
=> The "single-tether paraglider"
branch is very fertile for gliding and dynamic soaring.
=> That a paraglider (type of kite,
the gliding-kite type) is a compound: wing set w, tether set t, and
resistive set r
(w,t,r) is a summary that
will allow creative extension for paragliding and its sport's sector, as
=> That a paraglider need not be
stuck on soft canopy, but rather being open to any wing known to
aviation brings paragliding unlimited.
