On this day 60 years ago: de Havilland Comet performs first flight

On 27 July 1949 de Havilland chief test pilot John Cunningham, previously a famed night-fighter pilot, celebrated his birthday by leading his flight-test crew aboard the all-silver prototype DH106, the world’s first purpose-built jet airliner, and taking off on its maiden flight.

The de Havilland Ghost-powered DH106 was soon afterwards named Comet.

Here is a cutaway from our collection of the Comet:

To celebrate the Comet’s 60th anniversary, we took a look through Flight’s archives to find both the major stories and also the smaller details of the world’s first jetline.

    Barbara,

    You may be right but Wikpedia disagrees with you on the first “jet airliner”:

    The first airliners with turbojet propulsion were experimental conversions of the Avro Lancastrian piston engined airliner, which were flown with several types of early jet engine, including the de Havilland Ghost and the Rolls-Royce Nene, however these retained the two inboard piston engines, the jets being housed in the outboard nacelles and these aircraft were therefore of ‘mixed’ propulsion. The first airliner with full jet power was the Nene-powered Vickers VC.1 Viking G-AJPH, which first flew on the 6 April 1948.

    Keep up the good work,

    Regards

    I appreciate and respect your point of view.

    Well, maybe not so ideal – but big change to the world of internet.

    Sounds like there are some very interesting stories there indeed. It must have took time gathering the research here and so well done. Great stuff
