Visitors were terrified after the protective layer of the famous ledge in Chicago’s tallest building cracked under their feet on June 10.
The incident occurred at the observation deck on the 103rd floor of Willis Tower, an attraction that gives visitors unobstructed views of the city at 1,353 feet up. Along with the panoramic views, visitors can experience feeling suspended midair by walking on any of the glass boxes, known collectively as The Ledge, each extending a bit over 4 feet from the building.
