One World Trade spire offers unique view of NYC

A unique view of New York City emerged when video taken from One World Trade Center's newly-placed spire debuted.

The spire was raised on Friday to a height of 1,776 feet and sits atop a building rising where the twin towers were destroyed in the Sept. 11, 2001, terror attacks.

The video shows the workers below and Manhattan as the spire is hoisted in the air.

The 408-foot spire, which weighs 758 tons, includes a broadcast antenna and a light that will be visible from miles away to serve as a both a beacon for aircraft and a permanent signal of triumph over extremists who jolted the city and the country.

The spire gives the building the extra height needed to claim the status as the tallest structure in the U.S. and the third-tallest in the world, although building experts dispute whether the spire is actually an antenna — a crucial distinction in measuring the building's height.

The building is scheduled to open for business in 2014.
