The de Havilland DH.106 Comet is the world's first commercial jet airliner. Developed and manufactured by de Havilland in the United Kingdom, the Comet 1 prototype first flew in 1949. It features an aerodynamically clean design with four de Havilland Ghost turbojet engines buried in the wing roots, a pressurised cabin, and large windows.

The Comet tank or Tank, Cruiser, Comet I (A34) was a British cruiser tank that first saw use near the end of the Second World War, during the Western Allied invasion of Germany. The Comet was developed from the earlier Cromwell tank with a lower profile, partly-cast turret which mounted the new 77 mm HV gun.

The de Havilland DH-106 Comet 1 became the world's first pressurized civilian jet transport with its inaugural flight on May 2, 1952, flown by the Elba aircraft. Many companies were competing for this title, including the Avro Jetliner which flew its first test flight just two weeks after the Comet's first test flight in 1949.

The Comet 1 is widely thought to have been one of the biggest steps forward in aviation technology and design. Despite the awful tragedies, one of the positive legacies will be the advances in techniques for air accident investigation which were the most extensive and ground-breaking ever seen.

2019年12月25日 · Manufactured at a factory in Hatfield, around 30 miles north of London, the de Havilland Comet represented a major aviation breakthrough. At the time, the Comet seemed almost futuristic in appearance and promised a level of comfort that had hitherto been impossible for passenger planes to deliver.
