Whoops!  The glass floor of the Willis Tower's SkyDeck cracked last night, terrifying tourists who were enjoying views of the Chicago skyline.  The Skydeck is basically a glass box that hangs off the 103rd floor.  It's a popular sightseeing destination and attracts hundreds of tourists a day.

According to a spokesperson, it's not as serious as it sounds. He said:

This coating does not affect the structural integrity of The Ledge in any way. Occasionally, the coating will crack, as it is designed to in order to protect the surface of the glass

Ok... sure.  I still don't want to be the one standing on it when it starts cracking!  Check out the full report from NBC Chicago:

After this incident, would you still stand on the Skydeck?
