Fox News and the Atlanta Journal Constitution reported the outage was caused by a construction crew accidentally cutting a power line. But the airport said on its Twitter account that was not confirmed. Georgia Power, the area utility, said a fire damaged in an underground electrical facility that serves the airport. The cause of the fire is being investigated.
The airport is one of the busiest in the world, with more than 2,500 daily arrivals and departures, bringing more than 250,000 passengers through the airport on an average day.
