2 Window Washers Are Trapped Outside The 50th Floor Of One World Trade Center

Two window washers are trapped on a dangling scaffolding in downtown Manhattan, CBS New York reports.

New York's Port Authority has confirmed the incident.

The window-washing scaffolding is now hanging from the 1 World Trade Center skyscraper. A rescue operation is underway to retrieve the two workers.

CBS New York reports: "The washers were done cleaning the windows and were about to ascend to to the top of the tower when the cable that pulls the scaffold up became loose."

One World Trade Center is the tallest building in the Western Hemisphere.
