Skydeck In Chicago’s Tallest Building Cracks Under Tourist’s Feet [PIC]

Some California tourist got the scare of their life when the glass from Chicago's skydeck began cracking beneath their feet.

'The Ledge' as it's called, is on the 103rd floor and is a tourist attraction atop the tallest building in Chicago, the Willis Tower.

You can say these tourists got more then they paid for! They were also told it was unbreakable. OOOPS! LOL!
