Smoke in FAA Control Center Grounds Chicago Flights

All flights have been stopped from going in and out of Midway and O'Hare airports because of smoke in a radar facility in Illinois.

At approximately 11:30 a.m., all FAA workers were evacuated from the radar facility in Elgin, and operations were transferred to the FAA's Chicago Center in Aurora, which usually handles high-altitude traffic, The Chicago Times reported.

Flights bound for Chicago's airports are being held on the ground at their departure cities.
