Watch 1 World Trade Center get final pieces of its spire

Via NBCNewYork.com, a crowning achievement for a city that's been waiting more than a decade for this moment:

A spire adorned with an American flag has been hoisted to the roof of One World Trade Center, where it will eventually be raised and make the building soar to a symbolic 1,776 feet.

As construction workers and onlookers applauded, the spire was lifted by crane to a temporary platform Thursday and will be installed at a later date.

The 408-foot spire will serve as a world-class broadcast antenna.
