CHICAGO -- Tony Saldana and his cousins, who were in town from California, were sitting on the floor of The Ledge for a photo when it cracked beneath them on May 28, 2014.
"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.

Willis Tower officials said the protective coating cracked, but the glass underneath was structurally sound.
