If the viewing platform from the 122nd floor of the Burj Khalifa doesn’t induce vertigo, why not jump out of a perfectly good airplane at Skydive Dubai? The view of the Palm Jumeirah from 13,000 feet up will literally take your breath away—falling from that far above the ground tends to do that. If that sounds a little too extreme, give the biggest vertical wind tunnel in the world a go at Inflight Dubai. The wind in this tunnel, 16.5 feet in diameter, is cranked out not by the inescapable force of gravity but by four 2,000-hp electric motors that let you experience skydiving without ever jumping out of a perfectly good airplane. Never content to rest on their laurels, the folks at Inflight Dubai are aiming to break their own world record with an even bigger wind tunnel at Palm Jumeirah.
