RE: Anybody fly Ultralights?
I used to be an avid hang glider pilot. I would meet people who could only think about how dangerous it was, but they would also be surprised to find out that you'd take lessons to learn to fly these things, and progress to higher performing wings, more unstable flight conditions etc. as one gained experience. As it was pointed out, it's not a go cart, although they are dangerous in the wrong hands to. That extra dimension added to flight has a very solid lower limit, which means rapid deceleration, whether you go down in a Para Glider, Hang Glider, Ultralight, Private Plane or Commercial Plane, and that rapid deceleration will hurt you.
