Base jumping

Base jumping, also sometimes written as B.A.S.E jumping, is an activity that employs an initially packed parachute to jump from fixed objects, as with paragliding. "B.A.S.E." is an acronym that stands for four categories of fixed objects from which one can jump: buildings, antennae, spans (bridge), and earth (cliff).
