The washers were stuck for nearly two hours before their dramatic rescue, as New Yorkers looked on from the ground and people around the country watched on live TV. The scaffold accident, which officials said was caused by a malfunctioning cable, happened little more than a week after workers began moving into the nation's tallest building.
It was unclear whether the scaffold had been used on the 541-meter, 104-story skyscraper before or whether anything about the building's design complicates working a scaffold there. Officials stressed that firefighters had trained for various emergencies at the tower, the centerpiece of the rebuilt World Trade Center.
"It suddenly went from horizontal to nearly vertical," he said.
Officials haven't determined what caused the cable problem. The cables are controlled from the scaffold vehicle, the fire commissioner said.
About 100 firefighters rushed to the skyscraper, some of them lowering ropes from the roof so the workers could secure themselves and a two-way radio for them to communicate, Nigro said.
Firefighters also began inching another scaffold down the building as a backup rescue plan, but they were able to bring the workers to safety through the roughly 1.20 to 2.40 meters window hole by 2:30 pm.
Firefighters generally seek to cut out windows to make such rescues, but Nigro noted the trade center's thick glass: a double-paned inner layer and an outer pane.
The silvery skyscraper, which rose from the ashes of the Sept 11, 2001, terror attack, reopened last week to 175 employees of magazine publisher Conde Nast.
About 3,000 more Conde Nast employees are expected to move in by early next year, eventually occupying 25 floors of the USD 3.9 billion tower.
Steps away from the new tower are two memorial fountains built on the footprints of the decimated twin towers, a reminder of the more than 2,700 people who died in the Sept 11 attack.
