Hurtling at 160 kilometers or around 100 miles per hour, Jeb Corliss takes on his hardest challenge to date.

The American stuntman was in eastern China for his latest feat - flying through a very narrow valley, a mere three-and-a-half meters or 11 feet at its narrowest point.

Safely on the ground, Corliss was elated.

SOUNDBITE: Jeb Corliss, stuntman, saying (English):

"I was really worried that it wasn't going to happen. I am really glad I was able to do it, because it was so hard. This was so hard. This was really, really, this was the hardest thing I've ever done."

Corliss' other jumps include the Eiffel Tower in Paris and the Space Needle in Seattle.
