Hang gliding 1977
This page follows Hang gliding 1976.
Jim and Henry Braddock were second and first, respectively, at the U.S. national championships held at Heavener, Oklahoma, in July 1977. (Heavener rhymes with heathen, apparently.)
Powered hang gliding was going through its early stages at this time. It brought problems additional to those inherent in hang gliding. The man standing and speaking in the following picture is hang gliding photographer and columnist Bill Allen.
The original photo by Jim Theis, on which this artistic rendering is based, is of Dan O’Neil dune-soaring an Electra Flyer Cirrus 3 in a gale on the dunes at at Boca Raton, Florida, during tropical depression Anita in August 1977.
Grouse Mountain, where the photo by Leroy Grannis on which the preceding image is based, overlooks the city of Vancouver, Canada.
Hang gliding was still regarded as a spectator sport in the late 1970s. Here is a snippet about pilots John Davis and Glenn Hockett and competition promoter Don Whitmore:
Davis and Hockett and Whitmore were interviewed for national TV, and the remaining pilots packed their gear in the warm late afternoon sunlight. The city of Vancouver was shining, the ships in the bay swinging into the seabreeze.

The wing that Ash is flying in this picture is a Birdman Moonraker. Meanwhile, Dennis Pagen is flying a Bennett Phoenix 8.
In 1977, Electra Flyer (the manufacturer in Albuquerque, New Mexico, founded by former Learjet pilot Larry Newman) added the state-of-the-art Olympus to their successful Cirrus series of wings.
In this photo by Gary P, I am about to launch a Skyhook Sunspot, which appeared first in 1977, from the Merthyr ridge in February 1979. (Paul G. is on my front wires.) The glider belonged to the students’ union at the Polytechnic of Wales, where I was studying computing at that time.
Because computers were to be used in creating all things, I reasoned that programming was a skill that did not tie one too rigidly to any specific branch of science. After all, exactly that strategy paid off for astronaut David Bowman (who was a generalist, but not programming, as far as I recall) in Arthur C. Clarke’s 2001, a Space Odyssey (1968). So much for the career advice embedded in science fiction…
Immediately after launching on my first flight in the Sunspot, I entered a series of rolls, to the left, then to the right, then left, right, and so on, until after maybe 20 seconds my nervous system caught up with the new glider’s combination of roll inertia (more that I was used to) and damping (less) that caused a subtle delay in its roll and yaw response. This Sunspot swing was common on such first flights, I learned later. Indeed, such pilot-induced oscillation (PIO) affects many pilots regardless of ability. One of the most skilled pilots ever, the astronaut Mark Stucky, suffered from pilot-induced oscillation in 1977 when he returned to hang gliding after 15 months away:
I was heading home after another PIO-filled weekend, trying my best to visualize just what the glider was doing and what the proper response should be. I somehow figured it out and surprised everybody when the next flight went smoothly.

PIO is bad enough, but some later hang gliders required no out-of-synch pilot input to enter the so-called Dutch roll. (If you ever saw the opening sequences of the 1970s television series The Six Million Dollar Man, you have seen a crash caused by Dutch roll.) Hang glider pilot and NASA test pilot Mark ‘Forger’ Stucky determined that a high-performance hang glider of 1989 exhibited Dutch roll rather than being merely susceptible to pilot-induced oscillation (like the Skyhook Sunspot). See his article in Hang Gliding & Paragliding Vol39/Iss02 Feb 2009.
