  • Francis Melvin Rogallo granted an honorary doctorate degree from Kite Information and Technology Exchange Society of America  for his contributions in research on the Rogallo wing that found its way into the foundations of kiting,  hang gliding,  and other aircraft.  This adds to Dr. Francis Rogallo's legacy.
  • The Jack Lambie circle spins. Hang Loose project at a school. Plans follow. World coverage results. Near Long Beach,  California, Jack was a summer-school principal at Collins School summer session where he also taught a class in science and crafts.  Read here part of the story.  Hang Loose  was a large low cost tailed biplane hang glider using parallel-bars for the pilot to adjust for pitch and leg-mass swing to control roll/yaw, if possible. Media attention continued building the appetite for hang gliding that had been building from many other  influencing streams (aeromodelling, soaring, gliding, Rogallo phenomenon, kiting, water-ski kiting, space re-entry test vehicles, art, popular aviation, EAA, etc.). Lambie added a "for everyone now for pennies" deal to get flying by way of school groups and homebuilders. He carried with him his profound associations with the soaring community and aviation community which included Richard Miller who had already been influencing low-cost light personal flight through writings, modeling, exampling, and a carrying of only part of the Barry Palmer legacy via  prior Bamboo Butterfly fame and spread-to-the-world plans. Media coverage was extensive and effective.  Missing in the article linked is the fact that Richard Miller had already broached the meet's idea with Self-Soar Association; the actual planning and pre-meet meetings fully involved S-SA, Miller, Lambie and others; Low & Slow was one of the key vehicles for announcing the planned meeting to be on May 23, 1971. Lambie and Miller shared their mailing lists with Faust as S-SA did mailings and article support for the planned meeting, a meet that was to be "unplanned."  Special note: the jib-sail Bruce Carmichael aluminum Rogallo-winged machine had been priorly demonstrated to Faust in San Clemente, California, along with Richard Miller at a hill very near Bruce's home at the beach; Bruce Carmichael, a professional engineer had professional design experience with hydro-kites that ended up being a pleasant common-interest bridge between Bruce and Faust. Bruce Carmichael would later attend and participate in high-level conferences of flying wings where Jack Lambie would also be in attendance.

  • 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).








  • Petrel by Bob Trampenau: see history at Seedwings  (design in getting some 2008 modern materials redesigning).    See his history on the Petrel, Sunseed, and changes. See 1975 revolutionary Sensor.
  • Hang Glider Weekly was publisher  of some key facts on the innovative company Seedwings with founder, designer, inventor Bob Trampenau.  We have strong reason to look to roots of VG --variable geometry-- in Seedwings. The company's  Sensor's fiberglass curved wing tips and the enclosed cross bar were invented by Trampenau and first flown in 1976 and shown in Hang Glider Weekly. He further invented wire braced washout struts in 1978 now used on all topless hang gliders and the wrap-around Mylar leading edge pocket in 1979 all before the UP Comet. Trampenau continued inventing;  and he first HGMA certified the curved wing tip, enclosed cross bar, and an all-wire trailing edge reflex bridle stability system and VG. The wire-braced washout struts and wire-reflex bridles are the two most important stability safety features on today's hang gliders. Another safety-and performance-feature that is significant are the flaps on a hang glider. Seedwings owner Bob Trampenau invented the current flap system in 1992,  and as yet no one has copied it. The Seedwings  trademark is internationally operated out of the headquarters in California.

  • Special research call: Mike Koman built a fixed-wing hang glider of double surface and with double tapered wing (chord and thickness). It was of aluminum-tube and wire-rope construction. It had a double-tapered hollowed-out Styrofoam D-tube leading edge that extended back one third of the chord. The D-tube was made by hot wiring block sections of foam using handmade plywood templates of decreasing size from the root to the tip of the wing. Styrofoam ribs between the D-tube sections were capped with thin plywood strips. The trailing edge was thin wedge shaped wood. It was "shrink wrapped" with clear plastic by heating the garage in which it was built with an industrial heater to over 110 degrees. It had its own triangle shaped gray painted plywood trailer where the wings mounted vertically inside the trailer.

    David Cronk and Pat Conniary (or Conniry?) and Mike Koman flew it; it had a "nice glide angle," says Koman. According to Koman - Dave Cronk said it was "a beautiful wing". Russell Valderain (spell) ended up with the hang glider and may have some photographs. Al or Roger Sutton in Pennsylvania may have some photographs as the wing was largely built in their Sutton Brothers garage in Pennsylvania. The flights were partly in California where Dave and Pat flew it briefly at Redondo/Torrance Beach. Any information on this historical wing of the 1970s early, please send.

  • Finsterwalder & Charly - airsport equipment since 1974
    • 29 January 2013

      Dear BBC, Your lead sentence in the BBC Web article "Squash Falconer bids to fly off Mount Kilimanjaro" states: "A paraglider from Derby is attempting to be among the *first* people to fly from the the summit of Mount Kilimanjaro to raise money for projects in Tanzania."

      The second sentence states: "Squash Falconer, from Thulston, is already the *first* woman to fly from the summit of Mont Blanc.

      Clearly, the emphasis is on the act of being *first*.

      The truth is, people were flying from the summit of Kilimanjaro years before Ms. Falconer was even born. Please see http://www.charly-produkte.de/en/about-us.html

      Note that engineer Thomas Finsterwalder, Albert Leutenmaier and Heinz Walter made the *first* successful flights from Kilimanjaro in January of 1976 on Finsterwalder's 11 kg "Bergfex" backpack Rogallos. Two are pictured on the summit (the other snapped the photo).

      The unsuccessful flight implied on the Charly website was made in 1975, also on a Bergfex. The pilot landed in the jungle below the summit, so he was the very first to fly off Kilimanjaro. I do not have his name, although Thomas Finsterwalder likely does.

      Please also note also that NASA developed and defined 3-pole Rogallos as "paragliders" in the original literature and that the modern paragliding community explains that paragliding was invented at this time.

      By making no distinction between the two in your article; by placing emphasis on "first" but not mentioning who was actually first; by failing to qualify the claim with either the "first legal" or the "first modern paraglider"; and by stating the group is to be among "the first people to fly from the summit of Mount Kilimanjaro", you serve to re-write history.

      Also, if you wish to defend the article by saying the primary point is that the group may be the *first* "to raise money for projects in Tanzania," my opinion is that such a defense is misleading and that the BBC has sought to confuse aviation history with trivia.

         A hang glider in the form of an aerial wing of airfoil shape is disclosed. undefined
       The wing is defined by an outer envelope of flexible material inflatable to the airfoil shape and having a plurality of chambers therein each receiving an inflatable bladder. Air inlet openings are provided in the bottom portion of the envelope adjacent the leading edge of the wing. Either the bladders or the chambers are inflated with a gas lighter than air and, during flight, air enters the openings and fills the available space in the others of the bladders or chambers to provide a complete smooth airfoil shape for the wing. Shroud lines are employed to suspend a person beneath the wing during flight.

    Hang glider having inflatable airfoil Paul D. Hamilton envelope inflatable in flight by air entering an intake opening at the nose of the wing and exhausting through nozzles in the underside of the wing tips. A more efficient double-surface airfoil is thus provided which automatically changes its camber in response to changes in speed for optimum performance.
  • HPA Ikarus (Icarus) ground-effect-only man-powered aircraft flies in ground effect just a week after the Gossamer Condor won the big Kraemer Prize. The Ikarus took about 0.5kW to fly. 
              Theoretically we can fly a man-powered craft with less power in ground effect.  In ground-skimming during landing we often fly our hang gliders in ground effect; some hang glider pilots specialize in bleeding every inch out of the ground-effect flight sector for fun; appropriate wheels or skid can be used to have safer experiences when flying in ground effect. One needs to prevent catching the airframe on ground obstacles or the ground itself, as beaking or such catches can cause abrupt stops with perhaps fatal results. Be sure to get professional instruction for hang gliding.

    The glider was "invented" [Ed: sic, locally and regionally, but not globally, of course] in Mieussy Haute-Savoie, 35 years ago While Mieussy celebrates birthday paragliding this Saturday, June 22, back at the history of this invention born in 1978 on the tip of Point Pertuiset.

    June 1978. Bosson , Bétemps and Bohn already illustrated in competitions parachute. Their specialty: precision landing. But difficult to practice regularly when necessary, for each jump mobilize a plane and therefore pay for the fuel. "If instead of jumping from the plane, it jumped from a high point?". In answering this question, the three friends invented paragliding. The high point of the tip Pertuiset . The landing area:. Mieussy Mieussy then welcomes the France team skydiving but also in Germany. Yet it still will wait four years to pass paragliding training method to separate discipline. It will take one of these paratroopers, only interested in landing, take the time to fly. Now world famous "spot" of Pertuiset sees off hundreds of paragliders each year.

The research on this is still ongoing. Much more will be linked regarding the Canard 2FL. Yet to find out is the circumstances of Dr. Hans Farner's own final moments; it seems clear that notes in the literature are sometimes incorrect as he seems to get mixed up with the distinct other person Prof. Schürch.

 We have two speakers so far regarding an effort to clarify matters about the designer of the Canard 2FL:

Canard 2FL

(Jan. 8, 2008 from Gary Osoba)
I have received confirmation from the son of Ernst Ruppert, one of the partners in Aviafiber,
that Dr. Farner was not involved in the fatal Canard 2FL test flight. He writes:

" Hans Farner was not involved in the Canard accident. As far as I know he never was a Canard-pilot. The fatal accident was with Prof. Schürch from Zurich University which was quite a story since the University got involved in the development of the new Canard SCM version after the accident. It was not simply caused by stall/spin but was a far more complex chain of critical maneuvers based on the difficulties because the sailplane pilot Schürch was confronted by the unusual control system of the Canard 2FL."

(Jan. 8, 2008) Professor Michael Schönherr shares with us:

I remember the following:

1. At the end of 1978 or 1979 I got the message, that a professor of the ETH Zurich was killed by a Canard 2FL - accident, because, as reported, he had used the controls the wrong way.
The Canard 2 FL managed the directional control by rolling the front wing, the "canard-wing", so the lift of the front-wing delivers, when in a bank-angle, a lateral force-component and a torque around the vertical axis of the plane.

2. Later I heard from a person, involved in the accident-investigation, that the accident's reasons were clearly found:

Let´s imagine, that the glider makes a strong yaw-movement to the left. The pilot wants to compensate for that and rolls the canard-wing strongly to the right hand. Because of the high yaw-angle, the front wing however, with his now high right hand bank-angle comes into negative angle of attack, his lift becomes negative and delivers a lateral force-component to the left, just the opposite, that was intended. This way the Canard 2 FL plane came completely out of control until the impact.

Thus the investigation result.

(In 1980 I constructed a flexible model canard myself with the same front-vector control principle, with the difference that the canard wing could swivel down around a hinge in his leading edge, so that he did not accept negative lift. Thus I never had any control-problem, see also:

  • Abstract
    A remotely controlled powered aircraft equipped with engine, propeller and landing gear, radio-controlled from the ground and capable of towing a manned hang glider to an appropriate altitude. On reaching altitude, the pilot of the hang glider releases the tow, and the pilotless towing aircraft is returned to the launching site under radio control from the ground. During towing of the hang glider, two-way communication is maintained between the hang glider pilot and the towing aircraft remote pilot.
