Dubai could soon be seeing an increase in the number of adventure sports travellers it welcomes through its airports, as a new facility for skydiving has been opened to the public.Skydive Dubai told The National it has completed work on a 750-metre runway that stretches 550 metres into the waters of the Arabian Gulf. It replaces a shorter facility and means adrenaline junkies will be able to leap out of planes at almost 4,000 metres and then float over the sea before coming in to land.More than 800,000 cubic metres of sand had to be dredged out to construct the runway, which is made out of precast concrete and is the longest of its kind in the Middle East."I've seen runways finishing in the sea but not two-thirds of them in the sea ... It's definitely number one with visuals," said Skydive Dubai's Alan Gayton. Now the longer runway is in place, more skydivers can be catered for, with planes able to take 22 people up at a time instead of 18. The development is likely to become one of Dubai's top attractions, a big achievement for a company that started four years ago with a short runway in the sand and some portable cabins. Skydiving in Dubai had its profile raised earlier this year when rapper Flo Rida headed out to the emirate to film the video for Wild Ones and included Skydive Dubai in the footage.The city state will also host the World Parachuting Championships Mondial in November, which is likely to have even more people from all over the world booking adventure holidays there.Other attractions are also in the pipeline, according to Mr Gayton."There will be lots but we are not saying anything until it is all firmed up and it's nice to surprise people with something new. But this will be the extreme [sports] centre of the UAE," he added.Dubai's skyline is getting even more impressive for skydivers, as the Princess Tower in its marina was recently confirmed as the tallest building in the world.
