Wiki;
Off the Edge is a 1976 New Zealand documentary film directed by Michael Firth. It was nominated for an Academy Award for Best Documentary Feature.[2][3] The film features backcountry skiing, extreme skiing and hang gliding in the Southern Alps. Despite being classed as a documentary, it does have some semblance of a fictionalised storyline.
The trek up the glacier shows how Harty, Professional Hang Gliders (and their roadies ha..) really are.
"Pretty cool to ride the snow below and then the air above with the same skis on, and an original Hang Glider, on a glacier so far away. Jeff was a pioneer and started water skiing with a kite like Bill Bennett, then years later had a sailplane with an electric fold up propeller in the nose. He has made more take off's and landings in the Telluride Valley than most. This video has been packed away, and when I ran across it again I had to share it, it is a pioneer music video in itself, and John Heiney once said that it was a must see, because of the camera work by the producers. Just three years later the gliders had gotten so strong that they were doing loops in the Telluride canyon."
To all the pioneer Hang Gliders who made music, filmed and edited their adventures to stand in time.
