Frenchman climbs world's tallest tower. DUBAI, United Arab Emirates – A tiny speck more than half a mile (800 meters) in the air, a French skyscraper climber successfully scaled the world's tallest building Monday, even navigating the tapered spire that extends beyond the top floors of the Dubai structure.
Alain Robert's climb up the 2,717 foot-tall (828 meter) Burj Khalifa, took just over six hours. As night fell, a row of powerful spotlights shone on the side of the tower as Robert climbed.
Robert has climbed more than 70 skyscrapers, including the Empire State Building, Chicago's Willis Tower and the Petronas Towers in Kuala Lumpur.
Unlike on many previous climbs, the 48-year-old daredevil used a rope and harness to comply with organizers' requirements in the Gulf sheikdom that opened the tapering metal and glass tower in January last year.
An ambulance, with a stretcher at the ready, was parked alongside other emergency vehicles at the Burj's base.
Robert has climbed more than 70 skyscrapers, including the Empire State Building, Chicago's Willis Tower and the Petronas Towers in Kuala Lumpur, according to his website.
He conquered Taiwan's Taipei 101, which before the Burj was the world's tallest building, in 2004.
The tower's owner, Emaar Properties, said the half-mile-high Burj Khalifa has 160 habitable stories. An observation deck is located on the 124th floor.
Viewed from the ground, he appeared as a tiny dot difficult to follow in the darkness.
Emaar called Robert's climb a "momentous" event and said in a statement the climber "scaled the exterior of the tower in a record-clinching feat."
