Andy Torbet discovers that the Madagascan rainforest-dwelling Darwin's bark spider might be tiny but has a truly epic power - it makes the world's toughest natural fibre and uses it to make 25-metre-wide webs! To try to match this awesome arachnid, Andy is set the challenge of finding a way to fire a man-made rope to the top of a 30-metre-high building in Norway, before using top technology to help him climb it.

Adventurer Andy Torbet takes on one of his toughest assignments to date. Inspired by the spectacular speeds of the world's fastest animal, the peregrine falcon, he attempts to plummet through the skies at over 240 miles an hour. With the help of rocket scientist, Angelo Grubsic, Andy sets to work improving his in-air terminal velocity. He turns to engineering for help and jumps out of a plane wearing a unique pair of jet-boots, that Andy hopes will turbo-charge his skydive to match the speed of the peregrine falcon.
