Chicago Fire Department Plans Drill At Willis Tower Saturday
Chicago (CBS) -- If you see a lot of emergency lights around Willis Tower Saturday night, no need for alarm.
The Chicago Fire Department said a large, full-scale drill will start at the iconic building tonight at 5 p.m.
Radio traffic may sound like a real emergency, but the fire department wants everyone to know it's all a drill, planned well in advance.
The drill is set to last to close to midnight.
