It’s okay, you only need one hand to fly anyway. One hand to fly the plane, and you use the other one to pull chicks. It’s common knowledge.
From what I can see, it doesn’t seem like this fellow is wearing a parachute. I’m all for living on the edge, but I always took that expression figuratively. I suppose he’s not really that high up. If he landed just right, maybe they could harvest his organs. I’m not sure the form at the organ donor place has a check box for “glider pilot,” but there must be someone, somewhere who need a gently dropped kidney or something.
