The Federal Aviation Administration says all its personnel were evacuated from the Chicago Terminal Radar Approach Control, or TRACON, facility in Elgin at around 11:30 a.m.  TRACON provides radar approach control services for O'Hare and Midway and smaller airports in the Chicago area.

FAA spokesman Tony Molinaro says a ground stop is in effect for all flights in and out of both airports. Molinaro says inbound flights already in the air were handled by a backup facility in the city of Aurora. 

Elgin police said the evacuation was ordered because smoke was coming from a faulty motor in an HVAC (Heating, Ventilation and Air Conditioning) unit at the facility.

CBS Chicago reported that TRACON workers were allowed to return to the building shortly before 1 p.m. after firefighters deemed the building was safe and there was no fire, but it was unclear how soon air traffic would resume at O’Hare and Midway.
