Pacific Gull of San Clemente, California, was an early adopter of ‘sail clearance towers’ on the ends of the crosstubes, to which the top side wires were attached. They prevented the wires from digging a furrow in the sail. (Alternatives were an enormously tall king post or extending the cross-tubes out beyond the leading edges.) Nowadays the preferred method is to pass the cable through a hole in the sail to a connection slightly inboard of the leading edge tube.

On the subject of hardware, the following photo illustrates typical mid-1970s nut-and-bolt type fittings with Nicopress (or Talurit) swaged cables and a pin through a hole in the end of each bolt to prevent the nut coming off.

Incidentally, Sailbird should not be confused with contemporary manufacturers Sunbird or Sun Sail… There were so many hang glider manufacturers that it was hard to think up a unique name, although Pliable Moose (Wichita, Kansas) surely succeeded in that respect. (See Hang glider names.) Sailbird was based in Colorado Springs, Sunbird in Canoga Park, California, and Sun Sail in Denver, Colorado.

Seagull 5 and other Rogallos

The Seagull V flex-wing Rogallo used a rudder connected by ropes and pulleys to the pilot’s harness, a technique used also in the Quicksilver ‘semi rigid’ monoplane style hang glider. Together with its excessive dihedral, the rudder combined with weight shift provided turn control.

Ultralight Products, headed by automotive racing designer Pete Brock, set the standard for high quality hardware in hang glider manufacture.

The colors (well, shades) of the sail, the pose of the pilot and his shape collectively indicate to me that this is 11-year-old Hall Brock, son of Pete, in 1974.

Bridge too far

Standard Rogallo above ocean cliff by Dave Meyers

Britain was a little behind the USA in cliff flying, despite the ocean cliffs of Beachy Head on the south coast being adjacent a hill used as a flying site. They only flew the hill because they thought rotor from the cliff would demolish a hang glider. (Ted Salisbury’s earlier marathon at Dover, along the coast aways, seemed to be flown in front of and below the cliff top, which possibly engendered no confidence in the behavior of the air above a cliff.) Brian Wood, the first British champion (1974) was soaring the hill and he approached the Beachy Head cliff with trepidation, found rising air and immediately turned away back toward the hill. (We had no emergency parachutes at this time, so in-flight structural failure would likely be fatal.) Then he flew to the cliff again into the rising air and stayed a bit longer. Eventually, he soared high above the cliff and others joined him. (*)

Rotor (curl-over) from the cliff is a real danger, but it is behind the cliff. The air in front and above a cliff is not normally turbulent.

Hang gliders transported in this manner attracted attention, which might go some way to explaining why they were transported in this manner. (See also Cruising for a bruising under External links later on this page.)

Of course, hang gliders owed much to sailboat design and technology. The art of sail making and time-tested hardware allowed designs to advance quickly.

Tweetie

The Tweetie, designed and built by Australian Ron Wheeler, was a weight-shift controlled hang glider built of modified sailboat technology. British hang gliding pioneer Miles Handley rigged one at the inaugural meeting of the BHGA, held in December 1974. Handley then started work on a design of similarly ‘aeroplane’ layout, but of radically different geometry and construction.

A photo in the British weekly Motorcycle News of bike racer Stewart Hodgson flying a hang glider caught my (and others’) attention.


Notice the short horizontal tube near the top of the control frame on Mick Hurst’s glider. Many early production standard Rogallos had their hang points too far aft, requiring the pilot to pull in constantly to maintain airspeed. What went unnoticed on short top-to-bottom flights became annoying and tiring when hang gliders began to soar in stronger winds on larger hills. The addition of this ‘soaring bar’ with the harness risers passing in front of it mitigated the problem.

Despite the obvious crudity of this retrofitted correction, the harness risers slid over it from side to side easily, so it did not interfere with roll control. It did not adversely affect pitch control either, at least in my experience.

  1. This is fascinating–are you still hang gliding? It’s a sport I have always wanted to try. The only true flying that we humans can do, it would seem. I love its simplicity, its cleanliness. I can imagine a push-off, then lift, then…the surrounding. Being enveloped in whole new medium of yaw and pitch and roll, but without those words.

    Would I wind up killing myself if I just up and bought a glider?

    1. “Would I wind up killing myself if I just up and bought a glider?” — Yes! You need to get trained at a hang gliding school. You can find a list on BHPA.co.uk. Paragliding is easier to learn and is more popular than hang gliding, but I stopped paragliding a couple of years ago to concentrate on hang gliding, which is where I started really.

  2. Wow, memories. I flew a Ridge Rider on the south downs, was at the Minto championships, and later had a Chargus Vega. Happy days.

  3. In regard to pitch problems in 70‘s gliders, in my experience the most common one was that there was simply too much, leaving two usable speeds for a prone pilot: trim and elbows locked.

    In my early days on a Sky Sports Lark (a “standard”: Low Aspect Ratio Kite) preflight did include sighting down the keel for a certain amount of reflex, and if lacking, a twist of turnbuckle could bring it up to spec.

    My one occasion flirting with pitch divergence was when I sent my Sirocco II off for an upgrade ostensibly to improve handling. Standing keel pockets were in vogue and Sky Sports had come up with a retrofit that bent down the keel, added a small post where a keel pocket would be, and put two pulleys on the out and down deflexor wires at the nose. The bent keel required shorter flying wires to the keel. Well an error was made on my glider where they used the length of the smaller size Sirocco. End result was a glider that flew with negative bar pressure and was quite terrifying. My instructor was skeptical – that is until he flew it!
