Engineers inspect rollercoasters at Thorpe Park while suspended 200ft in the air With their sheer drops and high speeds, rollercoasters are terrifying at the best of times. But try doing the job of these two brave engineers. The two workers were spotted carrying out safety checks on all of Thorpe Park's white-knuckle rides. Scary: Rollercoasters are terrifying at the best of times, but try being these two engineers. They are pictured 205ft from the ground inspecting The Stealth Head for heights: The daredevil engineers also carried out safety checks on Thorpe Park's The Swarm Tough job: One of the engineers, Dave Stott, climbs The Swarm as he inspects all of the ride's track These astonishing pictures show the engineers dangling from the top of The Stealth and the park's most recent ride The Swarm - with its 127ft head first drop. Using harnesses and ropes to scale the rides, the workers methodically checked every section of track - even at the very top. The engineers, from inspection firm Leisure Technical Consultants, were carrying out the safety checks before the park opens on March 14. The Swarm, which opened last year, is Europe's tallest winged rollercoaster which the park says takes thrill seekers through extreme inversions and 'gut-wrenching near-misses'. Brave: The engineers were carrying out safety checks on all of the park's rides before it opens on March 14 Well deserved: The two men enjoy a warm drink and a packed lunch as they enjoy a break on top of The Swarm Upside down: This engineer dangles precariously on The Stealth as he carries out a vital safety check It is the UK's first winged rollercoaster featuring five 'terrifying inversions'. The 127ft head first drop takes riders under the wing of a genuine plane wreckage. Mike Vallis, from Thorpe Park, said: "As the nation's Thrill Capital, we are always looking to create the next level of adrenaline-inducing theme park rides for our guests. The Swarm pushes the boundaries with not only the roller coaster experience itself but also with the extreme near misses and apocalyptic style landscape that guests will encounter. Sure-footed: The engineers need to show good balance on top of The Swarm, which is Europe's tallest winged rollercoaster Acrobatic: The men used harnesses and ropes to scale the rides Hard working: The engineers needed all the skill and precision they have to carry out the safety checks Thorpe Park was built in 1979 on the site of a former gravel pit which was partially flooded, creating a water-based theme for the park. The theme park's first large rollercoaster, Colossus, was built in 2002. It attracts about 1.9million visitors a year and is the 10th most visited theme park in Europe.
