Skydiving

Skydiving is a sport in which participants jump or fall from aircraft at altitude. They can perform an assortment of aerial maneuvers before deploying a parachute to slow their descent, allowing them to come gently to rest on the Earth below. The sport is also known as parachuting, in a reference to that vital piece of safety equipment. People at different levels of physical fitness can participate in skydiving, as long as they are ready for an adrenalin-packed sport which can be both terrifying and exhilarating.
