(AP Photo/David Goldman, File) (Newser) – A pair of Atlanta-bound flights have safely landed after being targeted with what an airport spokesman called "credible" bomb threats, the Atlanta Journal-Constitution reports. Delta flight 1156 and Southwest flight 2492, from Portland, Ore., and Milwaukee, landed at Hartsfield-Jackson International Airport after being escorted by NORAD jets, WSB-TV reports. The FBI will interview passengers and the Atlanta police bomb squad is preparing to sweep the planes, officials say. Flight delays are expected as the airport suspends some air traffic. The threats were made on Twitter, WSB reports. As the Journal-Constitution notes, a user called "King Zortic" tweeted to Delta: "I have a bomb on one of your planes, but I forgot which one when I left the airport. Can you help me find it? " Another tweet from the same account reportedly said, " A bomb was placed on SWA2492. It will be detonated at a random time of my choosing."
