We caught a glimpse of coastal hang gliders and went to check out where they launch. They do a bunch of prep, probably much like parachutist, then snap into a harness/seat. With a flick of their wrists the parachute inflates, they turn 180 degrees and step off into thin air. They seemed to have great thermals and were able to stay aloft a long time and to do lots of stunts that dump air but then climb right back up. Looked like great fun. I was quite satisfied to watch from the ground though
