@amazeifystore: A jet didn’t fail because it was weak. It failed because tiny cracks kept growing. ✈️ The de Havilland Comet’s square windows created stress concentrations, while repeated pressurization cycles turned rivet holes into crack starters. Eventually, the fuselage tore apart in flight. Later tests reproduced the failure and changed how aircraft were designed for fatigue life. Would you have guessed the windows were the problem? Save this and follow for how engineers fixed the next generation of jets. #AviationHistory #AircraftEngineering #AviationFacts #EngineeringDisasters #AirSafety #DeHavillandComet #AerospaceEngineering #EngineeringHistory #FlightSafety
