A family visiting from California got the scare of their life on Wednesday during a visit to Chicago's Willis Tower Skydeck, the 103rd floor tourist attraction atop the city's tallest building.
One of the four glass enclosures jutting out from the side of the building, collectively called The Ledge, appeared to show cracks, said Alejandro Garibay, who was on the glass with his brother and two cousins.
A spokesman for Willis Tower said that what cracked was a protective coating on the glass structure and not the glass itself.
