World Trade Center window washers speak about their rescue

Two window washers who had been left dangling this week from the tallest skyscraper in the U.S. — One World Trade Center, which opened earlier this month — are speaking about their frightening ordeal today. 

On Wednesday, a cable suddenly developed slack, flipping a scaffold that left the workers trapped and dangling 68 storeys above a New York City street.

The window washers, Juan Lizama and Juan Lopez, were working on the lower Manhattan building's south side when one of the platform's four cables abruptly gave way.

The men held on to the teetering platform for two agonizing hours before firefighters used diamond cutters to saw through a double-layered window to pull them to safety.

The dramatic rescue, coming a little more than a week after the nation's tallest building officially opened, was followed by throngs of New Yorkers on the ground and many more around the world who were watching on live TV.
