A De Havilland Comet makes the first jetliner flight with fare-paying passengers

The de Havilland DH.106 Comet is a four-engine narrow body aircraft developed and manufactured by de Havilland in the United Kingdom. The world's first commercial jet airliner, the Comet 1 prototype first flew in 1949. It features an aerodynamically clean design with four de Havilland Ghost turbojet engines located in the wing roots, a pressurised cabin, and large windows. For the era, it offered a relatively quiet, comfortable passenger cabin and was commercially promising at its debut in 1952.
