Mystery Atlanta Woman Sneaks Onto Delta Flight Sparking Evacuation in Major Security Breach in Florida

Law enforcement and airline officials are investigating after a woman was allegedly able to access a Delta flight on Saturday without a boarding pass or ID.

The woman, who claimed to be from Atlanta, was escorted off the plane by Delta crew members after saying that she did not have valid identification and had thrown her ticket away. She was flagged after sitting in another person's seat and refusing to move, WSBTV reported.

The incident occurred Saturday afternoon on-board Flight 1516, which had been scheduled to travel from Orlando, in Florida, to Atlanta. The security breach resulted in passengers being delayed by several hours.

"We were told the woman was not cooperating [with] the authorities, and she had no ID or boarding pass, but was allowed on the plane in the first place," one passenger told local media outlet Fox 35.

The witness, identified as Casey Malone, said the plane started moving after the mystery woman was removed but then came to a stop on the tarmac, where it remained for another hour. Malone said passengers were made to disembark, where police, TSA agents and K-9 police dog units were waiting.

A spokesperson for the Orlando Police Department told Fox 35 officers who spoke to the woman said she did not have ID. The FBI was notified about the incident and will also investigate.

"She just kept saying, 'I don't drive. My I.D. is home in Atlanta,' and 'I don't have an I.D. to show you,'" a female eyewitness told WSBT, noting she was the person whose seat had been taken by the woman during the incident. "It was really scary, now that I look back on it," the passenger added. "I want to know what her intentions were, because it just shouldn't have happened."

In a statement, the airline said: "Delta apologizes to customers of Flight 1516 for the delay after a person not ticketed for that flight was removed from the aircraft.

A spokesperson added: "Security officials then directed precautionary rescreen[s] of everyone on-board. Delta is working with local law enforcement and the Transportation Security Administration on their investigation, and we are conducting our own review of this as well."

Despite the delays, the flight eventually took off and landed in Atlanta without incident. The TSA released a statement saying that the woman had been screened.

The homeland security division added: "We are working with law enforcement to investigate the incident at the plane and will not be providing any additional information at this time." It was not clear if the woman was charged. Her personal information was not immediately available.
