Spire Lifted To Top Of New World Trade Center

Ground Zero workers take photos as the final piece of One World Trade Center's spire is lifted to the top of the building in New York.

The 408-foot spire is hoisted onto a temporary platform on the top of One World Trade Center in New York. The piece will be attached at a later date.

As it once was: Firefighters and rescue workers battle smoldering fires as they search for survivors at the ruins of the World Trade Center in New York on September 13, 2001.
