BASE jumping
activity where participants jump from fixed objects and use a parachute to break their fall / From Wikipedia, the free encyclopedia
BASE jumping is a fringe sport in which a person jumps from a fixed place and uses a parachute to slow down before the ground is reached. "BASE" is an acronym that stands for each of the four jump location categories: from buildings, antennas, spans (bridges) and the earth. This last is similar to jumping off a cliff.[1] BASE jumping is an extreme sport. This means it involves speed, height, danger or spectacular stunts.[2]
