The reunions were private, taking place in a VIP room at O’Hare, but several of the families stopped to share their stories.

After nerve-racking hours following the attack and long days waiting for their return, parents escorted their kids through O’Hare Airport.

“It’s been the longest weekend of my life,” said parent Kathy Bennett. “This was horrible.”

Her daughter Brooke knew something was wrong when school officials told them to call home right away.

“They just put us in a room told us to call our parents and everything was ok ok then after we told our parents we were fine they told us there were bombings and shootings and stuff,” Brooke said.
