A Ryanair Boeing 737-800 departing Thessaloniki, Greece and bound for Memmingen, Germany is reported to have made an emergency return shortly after takeoff on Friday after a window became “dislodged” following an apparent engine-related incident. Multiple outlets say a piece of engine debris broke off and damaged the aircraft’s cabin window, leading to cabin decompression. Reports from Greek local media and industry or airport sources indicate that one passenger was partially sucked out through the damaged window, and that the passenger received medical assistance after the aircraft landed. Ryanair states the aircraft landed normally and that passengers returned to the terminal. The incident is widely described as forcing the flight to return to Thessaloniki. Separately, the U.S. National Transportation Safety Board said it will lead the investigation into the event, including the damaged window and circumstances surrounding the injury. Sources differ mainly on wording and specific details, but they consistently describe a dislodged window, an emergency landing at Thessaloniki, and a passenger injury linked to the window damage.
