The NTSB took over the investigation Thursday after determining that a July 10 Malta Air flight operated for Ryanair suffered its window incident in Greek airspace, where Greece delegated the inquiry under international rules; jurisdiction changed, but cause did not [1].

The Boeing 737-800 had departed Thessaloniki for Memmingen when a window dislodged and the cabin decompressed, and a 61-year-old passenger seated nearby was reported partly pulled through the opening before others drew him back; a hospital official reported neck and shoulder injuries and friction burns, which do not explain why the window failed [1].

The aircraft climbed past 15,000 feet, descended to about 6,000 feet and returned to Thessaloniki, while the NTSB had also been notified of a right-engine issue that Ryanair had not publicly addressed beyond repeating that the flight returned after the window came loose; the engine report, decompression and window failure remain separate parts of an unknown sequence [1].

Passengers reported a bang and dropped oxygen masks, observations that confirm disruption rather than which component moved first, and investigators still need the component's provenance, inspection and maintenance records, seat position, belt state, crew actions and available recorder evidence; advice to keep a belt fastened is prudent but is not a finding about this passenger [1].

No auditable same-day X post was recovered, leaving any cabin-video diagnosis unobserved rather than evidence; the videos show an emergency, but only the delegated investigation can establish the sequence among the failed window, decompression, reported engine issue, maintenance record and crew response.
