I have see to really cool types of ultr-lights on TV. One is the traditional look one that looks like a hang-glider with a prop and a 2 cycle engine and a seat. The second ine was way cool. It was what appearred to be a parachute with a seat suspended below it. Behind the seat and enclosed in a grill was a huge fan. The seat had what amounted to a roll cage. In the event of an engine failure, the "plane" come downs like a para-sail and no matter which way you hit the roll cage protets you. Has anybody ever used either of these ? Are they safe ? Are they as scarey as they look ?
