FOX NewsNBC News  Airport officials said a large portion of the facility had been affected and that repair teams had been working to address the situation since around 1:30 p.m. ET.Not everyone is buying the  fire  story however. This Twitter user believes that terror threat is the cause for the evacuation:The #atlairport has been evacuated, passangers are standing outside on the tarmac, no one is allowed to leave. I think a high level #Hivite was trying to get away, or they've disrupted a major terror attack. It's not being reported by @CNN (headquarters in Atlanta) #MediaBlackOut  Sarah Ruth Ashcraft (@SaRaAshcraft) December 17, 2017Many citizens are questioning the story they are being told about a simple power outage, and wondering why, in the largest airport in the world, there isn t any back up power?https://twitter.com/tonyabonya/status/942576639887663104Officials with the Atlanta Police Department told WSB-TV the airport is evacuating travelers inside.A spokesperson told The Associated Press that no areas outside the airport were affected by the outage. However, flights at Chicago airports O Hare International and Midway both have canceled flights   but it s not yet clear if they were canceled due to Atlanta s outage. Dealing with the power outage at the Atlanta airport was actually insane and I'll post other scary videos later. But the staff was having to slide down the escalators to help people and it was amusing. Finally in the car headed home. #atlantaairport #atl #atlantaA post shared by  sarahmanleyy (@sarahmanleyy) on Dec 17, 2017 at 2:54pm PSTDelta Airlines, which is headquartered in Atlanta, said it had canceled approximately 900 mainline and Delta Connection flights.
