Over the weekend Hartsfield was hit with a blackout, and of course it sent the world’s busiest airport into a frenzy. 400 flights were cancelled due to a fire that occurred in an underground service tunnel Sunday night (Dec. 17).

The airport was in the dark for 12 hours and according to reports, it may take days for everything to really be back up and running again.

Paul Bowers, Georgia Power CEO, is currently doing damage control as he apologizes for the blackout.

“We recognize the impact it’s had on thousands of people, and for that, we apologize”, Bowers told a Channel 2 news investigative reporter.

The outage left tens of thousands of passengers stranded. Hopefully, everything will be back functioning properly sooner than later, especially since the holidays are coming up.
