Wow, coming from a former hang glider pilot, that was just nuts on so many levels. First, with that short of a wing span, I'm guessing speeds in the 150 mph range at least. The fact the filming was done with a GoPro, we all know how wide angle they are, so all those close calls with the deck
, cliffs, and trees were even closer than they seemed. I loved the video, but I would never do it. In fact when I flew hang gliders, the only part I truly enjoyed was the flying clear of terra firma, my least enjoyable was take offs and landings.
