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 high above the ground tends to do that. If that sounds a little too extreme, give one of the biggest vertical wind tunnel in the world a go at Inflight Dubai. The tunnel, 16.5 feet in diameter, produces wind 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 an airplane. Tthe folks at Inflight Dubai opened an even bigger wind tunnel at Palm Jumeirah.
