Protective layer on The Ledge at Chicago's Willis Tower cracks as visitors stand on it

A trip to the top of the tallest building in Chicago turned into an even more harrowing experience in the sky for some visitors Monday when a protective coating on the glass-floored balcony began to crack beneath their feet.

The incident happened on the Willis Tower's 103rd floor, the location of the tourist attraction Skydeck Chicago where visitors can get a panoramic view of the city, Lake Michigan, and even parts of neighboring Indiana.

The attraction also features four glass enclosures collectively called The Ledge, which opened in 2009 and gives tourists the feeling of standing suspended in midair 1,353 feet above the ground and 4 feet away from the building
