Video: Wingsuit stuntmen leap from helicopter over Alps Professional base jumpers Chris McDougall and Dan Vicary made the jump over the Swiss Lauterbrunnen Valley in Bern last week. Video captured on their head-mounted cameras shows the pair soaring between craggy peaks as their wingsuits allowed them to fly terrifyingly close to the ground. The daredevils landed safely after deploying parachutes, but the sport can be extremely dangerous. In August Mark Sutton, the stuntman who took part in the Olympics opening ceremony dressed as James Bond, died while wingsuit flying in Switzerland. Chris 'Douggs' McDougall is a professional base jumper who has completed over 1,000 wingsuit jumps in 38 countries. He was the first person to base jump from the Al Hamra Tower in Kuwait, the country's tallest building standing at 1,350 feet (412 metres).
