Well-known BASE jumper Dean Potter and flight partner Graham Hunt died Saturday during a leap in Yosemite National Park.
After attempting a wingsuit flight from 7,500-foot Taft Point, their spotter heard "sounds that could have been impacts or could have been the noises made by parachutes snapping open," and was unable to contact them thereafter.
Rescue workers found their bodies after a daylong search; their parachutes were not deployed.
