Fear at 1,353 feet up but Ledge 'safe'
Officials at Chicago's Willis Tower have insisted the popular tourist attraction is safe after a glass ledge that juts from the building's 103rd floor appeared to crack beneath the feet of a visiting family.
The see-through glass boxes, known as The Ledge, are 1,353 feet from the street below and extend 4 feet from the building, which was previously called the Sears Tower.
Officials said the family wasn't in danger when the cracks appeared on Wednesday, forcing the attraction to be evacuated. Willis Tower said a protective coating covering the glass surface had cracked, rather than the glass itself. A spokesman said the cracks did not affect the "structural integrity" of the Ledge, which they claimed was designed to occasionally crack.
Alejandro Garibay, one of those inside the glass enclosure when the incident occurred, told 'The Chicago Tribune': "I thought it would be cool to get a picture of my cousins and brother. Then we started getting off and, as we pushed ourselves off, I could feel it cracking. It was completely shattering. I thought there was only cracked glass between us and 103 floors down."
