A 61-year-old Ryanair passenger was nearly ejected from flight FR1879 after engine debris struck the fuselage, shattering a cabin window at FL150 and triggering explosive depressurization. The seatbelt held the victim as fellow passengers restrained him against the slipstream, preventing fatal ejection during the emergency return to Thessaloniki. This uncontained engine failure mirrors Southwest Flight 1380, where similar debris ruptured a window and caused a fatality. Operators must prioritize engine integrity monitoring and reinforce cabin window resistance to external debris. The incident underscores the critical role of seatbelt usage during rapid decompression anomalies and highlights the sector’s vulnerability to catastrophic mechanical failures at cruising altitudes.
