This file picture taken 12 May 2003 shows a Air France Concorde on the tarmac of Roissy Charles de Gaulle airport. Concorde, which retires 24 October 2003 from commercial service, is the world`s first, and thus far only successful supersonic airliner. In all, 20 Concordes were manufactured, 10 in Britain and 10 in France. Behind Concorde`s sleek curves and technical prowess lurks a history strewn with technical, environmental and commercial obstacles. AFP
