Senior Master Sgt. Darryl LeBouef, of Nellis AFB in Las Vegas, prepares to take the plunge
If you've ever been to Las Vegas you'll probably be familiar with Stratosphere, the 1,149-foot-tall hotel and casino that towers above the famous Strip. If you're the adventurous type, you'd also know there's some fun to be had at the top in the form of three hair-raising amusement rides. Now there's a fourth. Claiming the title of the world's highest commercial decelerated descent, the SkyJump takes thrill-seekers on an 855-foot "controlled free-fall" at 40mph - think base jumping, but with a safety wire.
