Tourist saw their lives flash before their eyes, as the glass cracked beneath their feet.+ READ ARTICLE
A protective coating on a glass sightseeing box at the Willis Tower in Chicago has been replaced after cracking Wednesday night. Officials said no one was ever in danger, but for tourists, the experience was terrifying.
“Because you can see through it, obviously there’s the psychological effect that oh my gosh, something broke. But nobody was ever in danger,”Architectural engineer Michael Swanberg said.
There is a thick panel of glass that didn’t break that is designed to withstand 10-thosand pounds, which mean that thankfully tourists were never in any real danger.
