Ken Bryenton and friends documenting their flights from experimental home made hang gliders in the late 1960's to high performance gliders of the late 1970's. Ken was a pioneer during the emergence of the sport and for decades after but no longer flies. He is Canadian (hence the maple leaf gliders) but lives and travels between Ontario Canada and San Diego, CA, USA. This footage is all from Southern California. Ken was one of the flight directors at Torrey Pines Glider Port in San Diego.

This 8mm and super 8 film was digitally converted, edited and stabilized 50 years later by myself, Pete Axcell (Ken's nephew).

Wikipedia has an informative page on the History of Hang Gliding. As you can see, Ken was current with all the groundbreaking advances of the sport...
