Workers left dangling off World Trade Center Two window washers have been rescued after a terrifying ordeal trapped in their dangling scaffolding basket 68 floors above the ground at the new World Trade Centre tower in New York. Firefighters pulled the men into the building to safety after breaking through its highly-fortified glass window panes to reach the scaffolding unit, which was hanging at a precarious 75-degree angle. The men had been tethered by their safety harnesses inside the basket for about 90 minutes after a cable snapped during a routine cleaning. They were reported to be unhurt. The first tenants have just started to move into the newly-finished skyscraper, the tallest in the nation at 1,776 ft, which has been built at the site of the twin towers that were destroyed in the terrorist attacks of Sept 11, 2001. It took the firefighters about 45 minutes to smash a hole through the double glass panes which are highly reinforced in a building designed to withstand as far as possible any future terror attacks. The plaza at Ground Zero beneath the tower was cleared of visitors who had gathered around the 9/11 memorial reflecting pools in the footprints of the two towers that were attacked 13 years ago. As the drama played out live on American television, many participants on social media noted the perils of washing the windows one of the world's highest buildings.
