Chicago's Willis Tower has a tourist attraction called the The Ledge on the 103rd Floor.

For people were inside The Ledge (it is a glass enclosure, or ledge, that protrudes out from the building giving spectacular views of the city) when they heard cracking noises.

According to NBC-Chicago:

All four boxes of The Ledge, the 103rd floor tourist attraction atop Chicago's Willis Tower, were closed Thursday morning for what an official said was a routine inspection. 

The move comes hours after cracks appeared in what the official said was a coating designed to prevent scratches on the glass. 

"Skydeck Chicago is open today while the protective coating is being replaced," said Brian Rehme, a spokesman for public relations firm FleishmanHillard. "We have temporarily closed the four Ledge boxes for routine inspection we hope to reopen them shortly." 

The coating was replaced Thursday afternoon. Rehme insisted the structural integrity of The Ledge boxes were sound.

Since I am not very fond of heights, nobody would find me in that thing.

The Willis Tower is the formerly-named Sears Tower (although many people still call it by its old name).
