The WILLIS TOWER,formerly the SEARS TOWER, in Chicago has a skydeck that protrudes out at 103 stories in the air.
You can stand out of this ledge and view the city 103 stories below you and get an amazing and scary view of the city.
The last thing you want is to hear it cracking under your feet as you take photos with your friends and family.
That is exactly what happened to Tony Saldana and his cousins, who were in town from California, they were sitting on the floor of The Ledge for a photo when it began to crack beneath them on May 28, 2014.
Saldana stated: "All we see is the glass shattering," Tony Saldana, of Crest Hill, said. "We're thinking the whole thing's coming down. We're thinking we're about to fall 103 stories."
"As soon as I put pressure on my palm to lift myself up, I just hear it, and I feel the glass just shatter," Alejandro Garibay said. "You hear a noise, kind of like stepping on ice."
"I completely freaked out. I hopped as far as I could. I ran to the other side of the building trying to get as far away as I could from it," Saldana said.
