Alain Robert, a Frenchman known for scaling tall buildings, found his way to the top of the Burj Khalifa, the tallest building in the world, in about six hours. He wore a rope and harness and shimmied up a central column running up one side of the building.
The star attraction of the United Arab Emirates has been open for 15 months now. It's 2,716 feet from top to bottom. It has 162 floors. An observation on the 124th floor allows a 360-degree view of the city.
Robert is an internationally known climber, having scaled more than 70 skyscrapers. Among his conquests are the Taipei 101, the Petronas Towers in Kuala Lumpur, the Willis Tower in Chicago, and the Empire State Building in New York City.
