A Ryanair flight heading to Dublin was forced to return to Porto, Portugal, shortly after takeoff due to a security concern raised by a passenger. The incident involved a 48-year-old Brazilian woman who reportedly told a flight attendant she was being followed by three individuals. She handed the attendant "sheets of paper" detailing her claim and asked him to pass them to the pilot. The flight was then redirected back to Porto, where the woman was removed from the aircraft after landing. The flight, Ryanair 7073, departed Porto again just before 1:30 a.m. local time and arrived in Dublin approximately two-and-a-half hours late, around 3:15 a.m. According to a Ryanair spokesperson, the flight returned to Porto due to a "false security report," which was quickly resolved, allowing the plane to continue to Dublin after a delay of two hours and 33 minutes. The airline did not comment further on the specific details of the passenger's claims. Portuguese media, including the newspaper Correio da Manha, reported that the woman was identified by local authorities after being removed from the plane. However, police did not confirm the validity of her allegations. Other Portuguese outlets described the woman as having displayed "disorderly behavior" and being escorted out of the airport by police after the incident. These reports suggested that her actions prompted the pilot to send a specific "squawk code" to air traffic control—a discreet signal used to indicate potential unlawful interference, such as a hijacking or cockpit intrusion. The incident highlights how security protocols are triggered even in cases where the threat is later determined to be false. While the flight was delayed, the airline emphasized that the situation was resolved quickly, and the plane continued its journey to Dublin without further incident.
