Operations at Chicago’s two airports are returning to normal after an electrical problem at a regional radar facility forced a shutdown of all incoming and outgoing flights.
Tuesday’s three-hour halt resulted in more than 1,120 cancellations at O’Hare International and Midway International airports.
By Wednesday morning, about 100 flights to and from O’Hare were scrapped and a few dozen more were delayed. That’s according to the aviation tracking website FlightAware.com. There were only minor disruptions at Midway.
The ground stop was triggered by a bathroom exhaust fan in a ceiling that overheated and melted insulation on some wires. Smoke was pushed through the radar facility’s ventilation system and into the control room.
