A flurry of threats on Twitter over the weekend caused flight delays and prompted the Air Force to scramble F-16 fighter jets to escort two planes.

Two flights bound for Atlanta were escorted by the fighter jets to the Hartsfield-Jackson Atlanta International Airport on Saturday because of the Twitter threats, a spokesman for the North American Aerospace Defense Command (NORAD) confirmed to The Washington Post.

Delta Flight 1156 from Portland, Ore., and Southwest Flight 2492 from Milwaukee landed safely, according to NORAD’s Preston Schlachter.

According to the Atlanta Journal-Constitution, a Twitter user directed several messages at the Delta account, claiming to have put a bomb on one of its planes.

“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?” one tweet read, according to the AJC. “It was from Portland to Atlanta, I forgot the flight number, though. It was something like DL156 or DL 1556 I forgot the order,” said another.

The same account tweeted to Southwest Airlines with a similar, though more specific, message.

“A bomb was placed on SWA2492. It will be detonated at a random time of my choosing,” it read, adding: “If anything happens to me I’ll make sure that more flights are targeted. I strongly suggest you don’t try anything stupid.”

That account has since been suspended, and it is unclear whether these messages prompted the NORAD response.

The next day, more security concerns caused authorities to evacuate two flights — a JetBlue flight from Long Beach, Calif., and a regional SkyWest plane traveling from Phoenix — upon their arrival at the Seattle-Tacoma International Airport.

Passengers were removed from the planes and bused to their gates from the airport’s third runway, according to the Associated Press.

FBI spokeswoman Laura Eimiller said social media threats were responsible for the extra precautions on those flights, according to the AP.

About 4 p.m. Saturday, another Delta flight, 1061 from Los Angeles to Orlando, was diverted to Dallas because of “security” concerns, the airline said.

According to KDFW, a user tweeted to Delta and several other airlines that there were “planted explosives” on the Delta flight.

“@FOXNEWS WE HAVE PLANTED EXPLOSIVES ON DELTA FLIGHT #1061 FROM LA TO ORLANDO, WE ARE ISIS, WE ARE HERE, YOU WONT BE,” the tweet said, according to the station.

That account has been suspended. It is also unclear whether this specific threat caused the flight to be diverted.

No bombs were found during any of the incidents.
