A spire adorned with an American flag has been lifted to the roof of One World Trade Center. It will eventually be raised and make the building soar to a symbolic 1,776 feet.
Construction workers and onlookers applauded as the spire, which will serve as a world-class broadcast antenna, was lifted by crane to a temporary platform on Thursday.
