- the world's first commercial jet plane, operated by BOAC (British Overseas Airways Corporation) from 1952. Comets were almost twice as fast as earlier planes, but three of them crashed in 1953-54 because of problems in the metal from which they were made. They stopped flying until 1958 when an improved type of Comet offered the first jet service across the Atlantic Ocean.彗星：1952年由BOAC（英国海外航空公司）运营的世界上第一架商用喷气飞机。彗星的飞行速度几乎是早期飞机的两倍，但是其中三架在1953-54年坠毁，原因是它们所用的金属存在问题制作。他们停止飞行，直到1958年，一种改进型的彗星在大西洋上提供了第一架喷气机服务。
