On Saturday, CNN reported that two passenger planes had been escorted by fighter jet to Atlanta's Hartsfield-Jackson International Airport to be searched, the result of an online bomb threat military officials "deemed credible." It soon became clear, however, the threat came from a source most of us would treat pretty skeptically: some dumb tweets from an obvious troll.

As BuzzFeed, The Verge and others reported, the threat was apparently made by the Twitter account @kingZortic, which, by playing coy, got Delta Airlines to flesh out a key detail about the supposed bomb.

Shortly afterward, the airport announced normal operations had resumed.
