WATCH: The World's Longest Zip Line

Welcome to Ras Al Khaimah in the United Arab Emirates, home to the most heart-stopping zipline ever imagined. Jebel Jais Flight, named after the mountain from which daredevils begin their epic 1.75 mile zipline journey, was opened a few months ago and has since been certified by Guinness World Records as the longest zipline in the world. The facility is about an hour north of Dubai, cost $4 million to construct and can host up 240 people a day with a top speed of 93mph.
