Jet airliner
The de Havilland Comet begins passenger jet service, halving journey times.
The Comet 1 entered service in May 1952, cruising near 740 km/h with a pressurized cabin above the weather. Fatigue failures from square-cornered windows grounded it in 1954, and the investigation founded modern metal-fatigue engineering. Later jets built on those lessons.
