Wow, A Guy Plummeted 40MPH off a 1,000 Foot Cliff and SurvivedCasey Chan5/21/13 9:13pm501EditPromoteDismissUndismissHideGo to permalinkDon't watch this video. No, seriously, it's really rough. The best thing is that Matthew Gough, the guy who plummets while base jumping, actually survived the fall with only minor injuries. He hit the ground at 40mph from a 1,000 foot cliff because his parachute malfunctioned. The footage is taken from his helmet cam.
