The video I responded to you with reminds me of a hang glider accident that I once had. I was soaring for an hour or so in some foothills when the sun went down. I was landing in a cow pasture. The warm ground in the pasture was causing rising air currents which meant that I floated far beyond where I had intended to land. At the last moment I had to make a sudden sharp turn to avoid power lines. The lower wing tip made contact with the grass and catapulted me into the ground. I hit my upper arm on the control triangle so hard that it pretzeled. Contact was close enough to my shoulder that my arm did not break but I got one heck of a knot in my left deltoid. It hurt for months. The only damage to the hang glider was the one down tube in the control triangle. $10 for a new tube and it was all good as new. Cheap parts and the ability to fix them yourself is an advantage of hang gliding.
it??
Which one - arm or control triangle??
