Kite Tubing

This is probably one of the more dangerous sports on our list with several deaths and numerous injuries on record over the past 5 years. Its actually a variant of towed tubing wherein the tube becomes airborne. The danger arises from the fact that tubes are not specifically designed to be airborne, which means they are hard to control, which means the landings can be a little rough. Evidently wings serve a purpose, who d of thunk it?
