CHICAGO - Wednesday night at the Willis Tower's 103-story new viewing area, the protective glass covering began cracking as a family looked out onto the city. One of the family members told WMAQ-TV what happened then:
“I walked them over so they could see and they were totally shocked and asked us to step away and then proceeded to start calling staff and techs and I don’t know who else. When we pulled our phones to start recording and take pictures they asked us to leave right away,” he said.
But while being scary, the covering is doing exactly what it's supposed to do, a Willis Tower worker said.
“Occasionally this happens, but that’s because we designed it this way,” he said. “Whatever happened last night is a result of the protective coating doing what it’s designed to.”
