British aviation manufacturer de Havilland unveils the prototype of the DH106 Comet 3, a jetliner model derived from the earlier DH106 Comet 1 and 2. The Comet 3 (G-ANLO) reverses into place on the tarmac of de Havilland’s H Hatfield Airfield in Hertfordshire, England. The Comet 3’s tail displays the aircraft identifier (G-ANLO) and the British Union Jack flag.
