Longest zipline to be thrice the length of Burj Khalifa
The world's longest zipline will open in the UAE in December, and will be thrice the length of the world's tallest skyscraper Burj Khalifa. It will start 1,934 metres above sea level, from the Jebel Jais mountain peak, and will be over 2,800 metres long. "It's the closest you can get to the experience of flying," a tourism official said.n
