Base jumping

BASE jumping, also sometimes written as B.A.S.E. jumping, is parachuting 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 . In the USA, BASE jumping is currently regarded by many as a fringe extreme sport or stunt. As of 13 January 2015 the online "BASE Fatality List" records 248 deaths for BASE jumping since April 1981.
