de Havilland Comet jet airliner. . For the 1930s racing aircraft, see de Havilland DH.88.
The British de Havilland Comet first flew in 1949 and is noted as the world's first commercial jet airliner to reach production. The Avro Ashton and the Vickers VC.1 Viking non-standard variant fitted with Rolls-Royce Nene turbojets had flown earlier but were experimental models. Early Comet models suffered from catastrophic metal fatigue, causing a string of well-publicised accidents, and the aircraft was withdrawn temporarily and redesigned. The Comet 4 series subsequently enjoyed a long and productive career of over 30 years, although sales never fully recovered. The Hawker Siddeley Nimrod, the military derivative of the Comet airliner, is still in service. In 2007, the original decades-old airframes were being rebuilt with new wings and engines to produce the Nimrod MRA 4, expected to serve with Britain's Royal Air Force until the 2020s, more than 70 years after the Comet's first flight.
