Construction crews at the World Trade Center hoisted a flag-bedecked spire to the top of the site's signature One World Trade Center building Thursday.
Workers raised the spire to a temporary work platform atop the structure's roof, where ironworkers can later permanently attach it.
When fully installed, One World Trade Center will stand a symbolic 1,776 feet high, making it the tallest building in the Western Hemisphere. The 408-foot spire will serve as a broadcast antenna. — usatoday.com
