Jeb Corliss was among the competitors taking part in the semi-finals of the first Wingsuit Flying World Championship.

The world's top wingsuit fliers took to the skies over the Chinese city of Zhangjiajie on Wednesday, jumping off a 1,400m-high ledge on Tianmen Mountain.

Displaying some extreme aerobatics, the fliers zoomed across the valley, passing under a cable car before opening their parachutes and landing on a mountain road.

The aim of the challenge is to complete the whole course in the shortest time possible.

Julian Boulle, from South Africa, took the crown with the first wingsuit flying world record of 23.41 seconds on the final day of the competition on Thursday.

In second place was Norwegian flyer Espen Fadnes who came in with a time of 23.55s, who was followed by Brit Jame Boole at 23.84s.
