Newlyweds Jesus and Karly Pintado were visiting Chicago’s Willis Tower on the night of June 10 when they noticed the building’s Skydeck was cracking.

“I hear a noise like ‘ksh ksh ksh’ and it cracked,” Jesus Pintado told WTHR. “A woman with two little kids and they looked like pale because the whole glass is cracked.”
