FBI investigates bomb threats against Southwest, Delta flights

ATLANTA -- FBI and law enforcement officials are investigating online bomb threats on two planes that safely landed in Atlanta. The threats were directed at two passenger jets in flight, bound for Hartsfeld-Jackson International Airport.

"They made an announcement that the TSA would be meeting the plane," said passenger Brian Benett.

Starting at noon, a Twitter account with the handle @kingZortic began making threats against two inbound flights -- Delta Flight 1156 from Portland and Southwest Flight 2491 from Milwaukee.

The government sent two F16 fighters to escort the planes in. Both flights landed safely.

The tweet to Delta Assist reads: "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?"

Delta responded with: "We take all threats serious and have reported your comments to our corporate security team for further review/action."

The airline went on to ask: "Where did you leave the bomb?"

To which @kingZortic answered: "It was smuggled through one of the back entrances."

Anxious passengers were evacuated onto the tarmac where bomb squads went through their luggage.

"You could look out the window and see men with machine guns and other menacing things," said passenger John Larkin.

Fellow passenger Dan Hilgendorf said, "They went through your bags with bomb-sniffing dogs."

Once the all-clear was given, passengers were put on buses to finish their disrupted journey.

The FBI is on the hunt for the tweeter, @kingZortic.

"You leave a trail whether you want to or not," said FBI Special Agent Britt Johnson.
