The United States National Transportation Safety Board (NTSB) has taken charge of the investigation into a mid-flight window failure on a Ryanair Boeing 737-800 that left a passenger partially pulled through a shattered window over Greece.
The NTSB confirmed on 16 July 2026 that, although the incident occurred in Greek airspace, the Hellenic Air and Rail Safety Investigation Authority had elected to delegate the inquiry. Under Annex 13 of the International Civil Aviation Organization (ICAO) framework, the state where an accident occurs may hand the investigation to another authority. "The NTSB accepted the delegation and is leading the investigation, with Greece participating as the Accredited Representative," the board said.
The event itself took place on 10 July 2026. Eyewitness accounts described a passenger being saved by his seatbelt after a cabin window shattered in flight, pulling him partly out of the aircraft. According to those accounts, the man's "whole head, neck and shoulders were outside the window" and he was held in place by people seated beside him.
The aircraft involved was a Boeing 737-800 registered 9H-QEU, operated by Malta Air on behalf of Ryanair and powered by two CFM International CFM56 engines. The 18-year-old airframe was operating between Thessaloniki International Airport (SKG) and Memmingen Airport (FMM) in Germany when the window failed.
A report by Greek broadcaster ERT News indicated that information it had received suggested the window may have broken after being struck by a piece of the engine. That remains an unverified line of inquiry rather than a confirmed cause, and establishing exactly why the window failed will be a central task for investigators.
The NTSB is best known for leading US domestic accident inquiries, and its involvement here reflects both the technical complexity of the event and the fact that the 737 is a US-designed aircraft. As the Accredited Representative, Greece will remain closely involved, and manufacturers and operators are typically invited to contribute technical expertise to such investigations.
Window and fuselage-integrity events are rare on the 737 family, one of the most widely operated aircraft types in the world, which is why any in-flight failure of this kind draws significant scrutiny. Findings from the investigation could take months to emerge, and any safety recommendations would follow the board's established process.
