Always pushing their limitsSome people are ready to go very far for thrills and cold sweats! Like Antti Pendikainen, who jumped from a hot-air-balloon without a parachute.A new level of thrill-seekingWelcome to Dubai, in the United Arab Emirates! It is there that the two base jumpers, Chris Douggs McDougall and Jimmy Pouchert went to test a giant human catapult! The machine flung them from 0 to 200 kilometres an hour in one second flat, at a height of 90 metres like real human missiles launched into the void.Real daredevilsThe two men threw themselves out without being attached only equipped with one parachute each, which they opened at the last minute. Fortunately, the two friends are used to these kinds of acrobatics and therefore did not encounter any difficulties. We would not have the courage to do the same.
