A pair of daredevils have taken part in what they claim to be the UK's first ever - tandem BASE jump. The pair of thrill-seekers are part of the extreme sports collective Mountain Man BASE, which organised the jump from a chalk cliff near Beer Head, on Devon's Jurassic Coast. Images show the pair, assisted by a crew in the early morning of August 8th, when they took the plunge to the beach at the bottom of the huge cliff. The crew prepared for two years for this jump as there was "lots of scouting out of logistics, design of kit tailor-made for the project, deciding on the location". Mountain Man BASE ensure that all of their activities are within the law as they claim to be practitioners of 'ethical BASE'. Devon Coast Guard was informed prior to the jump. Incidentally, this part of Devon hosted the UK's first ever BASE jump from an 'Earth exit'. BASE stands for 'Bridges, antennas, spans (bridges), and Earth' and jumpers 'exit' from these locations. A spokesperson for Mountain Man BASE said: "Mountain Man BASE is a pioneering team of extreme sports athletes including BASE jumpers in the UK. "We're known for breaking new ground in the domain of extreme sports, taking things to the next level recently with the UK's first ever tandem BASE jumps. "This was a massive success, a UK first representing months (and years) of teamwork incorporating planning, designing, and testing equipment and techniques."
