Odds of dying: 1 in 2,317
Base jumping ranks as first among 11 most dangerous sports in the world. The article How dangerous is BASE jumping? estimates that one fatality happens in every 2,317 jumps, while nonfatal accidences occur in every 254 jumps. Analyzes of fatal jumps show that majority of victims jumped from the cliff, 71.5 percent of them, followed by the antenna, bridge, and building. The danger of base jumping lies in the fact that jumps are performed from lower altitudes which means that the jumper has slower airspeeds and thus less time for establishing full control over his body and parachute openings.
