WTC Antenna Keeps Willis Tower As America’s Tallest Building

A tiny detail may keep the Willis Tower in place as America’s tallest building says the Chicago Tribune.  The spire planned for the new One World Trade Center tower would put its finished height at 1776 feet, and give it an edge over Willis’ 1451-foot span. But the spire is actually a broadcast antenna—and spires count in a building’s height, but antennas don’t.
