'Photographic impression of Concorde, the Anglo-French supersonic airliner, appearing over the Thames Estuary. At this point on its approach to London, Concorde would be flying at around 300mph. Concorde is designed to fly at speeds of up to 1450mph - twice the speed of sound. It will fly from London to New York in less than three and a half hours and one aircraft will be capable of making two return flights in one day.' Concorde made its maiden flight in 1969, and entered commercial service in 1976. All Concordes were grounded after one of the aircraft crashed near Paris shortly after take-off on 25 July 2000. Flights resumed in January 2001, but in 2003 British Airways announced that it would be retiring Concorde from service in October that year.
