Daredevil Dean Potter has died while attempting a wingsuit flight from the 7,500 ft Taft Point promontory in California’s Yosemite National Park on May 16, a park spokesman said.

Dean Potter, 43, was one of America’s best extreme athletes.

Graham Hunt also died when their attempt to fly at high speed through a narrow gap in the skyline went wrong.

Rescuers found the bodies soon after contact had been lost with the men.

No parachutes had been deployed, reports say.

Dean Potter was regarded as a hugely innovative rock climber.

He was the first to climb Yosemite’s three most famous big walls in a single day.

Dean Potter was also renowned for his high-line walks and high-risk parachute jumps, some of which he carried out with his dog.
