BASE jumping, also sometimes written as
B.A.S.E. jumping, is
parachuting or
wingsuit flying from a fixed structure or cliff. "BASE" is an
acronym that stands for four categories of fixed objects from which one can jump:
building,
antenna,
span, and Earth (
cliff). Due to the lower altitudes of the jumps, BASE jumping is significantly more dangerous than
skydiving from a plane. In the U.S., BASE jumping is currently regarded by many as a fringe
extreme sport or
stunt. In some jurisdictions or locations, BASE jumping is prohibited or illegal; in some places, however, it is permitted, like Perrine Bridge, in Twin Falls. BASE jumping became known to the wider public by depictions of BASE jumping in a number of action movies.
