Cranes Install Base of Spire at 1 WTC

Workers at the rising 1 World Trade Center on Tuesday install the first piece of the spire that will make the 104-floor skyscraper the tallest in the Western Hemisphere. Dozens of construction workers were on hand as two giant cranes on the roof lowered the massive, round piece of steel into its socket — the base of the 800-ton, 408-foot spire that will also serve as a world-class broadcast antenna.
