World's tallest tower in Dubai reopens

The observation deck of the world's tallest skyscraper reopened Sunday in Dubai, two months after an elevator malfunction left visitors trapped more than 120 stories above the ground and forced it to close. Dozens of tourists were lining up Sunday for tickets to take an elevator to the 124th floor of the half-mile-high Burj Khalifa, where the tower's observation deck is located. The deck was shut in February after an elevator packed with visitors got stuck between floors for 45 minutes before rescuers dropped a ladder into the shaft so those inside could crawl out. Two months later, it's still unclear what caused the elevator to fail. Most visitors who paid the 100 dirhams ($27) for a 3-minute ride to the deck. At 2,717 feet (828 meters), the tapering, silvery tower ranks as not only the world's highest skyscraper, but also the tallest freestanding structure in the world.
