In France, Sud-Aviation (later Aerospatiale) was designing an SST aircraft with capacity 70/80 passengers, plane that would replace the Caravelle. Both designs were very similar, despite some differences in range and weight.In November 29 th 1962 an agreement was signed between the two nations and two planes were to be developed, a long range in Britain and a short-range in France. Later, French accepted the idea for a plane capable of trans-atlantic routes and a common plane was developed.

The final plane had about 100 seats and increased weight 148,004 kg. The Olympus engine was re-designed and the Olympus Mk 593B was created. The wing of the Concorde was very thin and was equipped with six elevons and there wasn't horizontal tail. These elevons had the disadvantage that couldn't be used to increase the drag and the lift force. The aircraft was carrying 119,265 liters of fuel in tanks located at the wing. The bigger part of the fuselage is constructed from aluminum. In addition, the aircraft uses very complicated systems that were not used before. The assembly line was in Britain and France but France was constructing the 60% of the fuselage and wings, because Britain provided the engines. The Concorde made its maiden flight in March 2 nd 1969 and the British prototype flied one month later.

By 1975 almost every big city was being visited for Concorde, proving its great reliability. Later, problems came up. The price of fuel went up and Concorde was now very expensive to use. So, its flights were dramatically decreased.

By 1986, British Airways was using 12 Concordes and Air France 5. Many co-operations were cancelled, like the one between British Airways and Singapore Airlines and the one between British Airways and Braniff. At that time, the two airlines started using the Concorde in different ways. They were giving the plane for charter flights during the holiday season. Furthermore, one of the Concordes was painted in the Pepsi colours, as the company wanted to advertise its new logo.

The first major hit to the aircraft's reliability was a crash. In July 25 th 2000, a Concorde of Air France crashed just before the take-off killing all its passengers. The plane was to make a charter flight. This accident was the result of many fatal coincidences and not because of a problem concerning the plane itself. That's why Concorde restarted flights some months later with both airlines and gained the trust of its passengers.
