Swiss tightrope walker Freddy Nock has walked along a tram cable in Germany's tallest mountain without a harness and safety nets that will catch him if he falls to set a new world record for the stunt.

At 9,655 feet high in Zugspitze mountain, it was the highest tightrope walk ever made. Nock walked along 3,264 feet of inclined cable and reached the tram station in 50 minutes on Sunday. The ground was 426 feet below him.

Nock started the world record attempt Saturday but postponed it due to bad weather. About 1,800 people watched him tightrope walk on Sunday.

The event was at the time a charity event. Nock raised $18,617 in donations for the feat.
