Concorde was the first and, so far, the only commercial passenger plane capable of supersonic flight. Its development resulted from Anglo-French collaboration in this field, through the British Aircraft Corporation (BAC) and Sud Aviation (shortly thereafter to become part of Aerospatiale), plus the SNECMA and Rolls-Royce engine manufacturers that signed an agreement in 1962 for this undertaking project. Its cabin could hold 100 passengers, all of them in first class. In total two prototypes were manufactured (the first one of which made its maiden flight on 2 March 1969), two series prototypes and three pre-series prototypes and 13 series units. These last ones were acquired by Air France and British Airways. Regrettably, despite the unquestioned advance it represented in the world of commercial aviation, its success was short-lived due to the high price of the tickets and the equally high cost of acquiring the aircraft. In addition, unfortunately it was a dreadful accident that brought down the curtain on this aircraft: it happened in Paris on 15 August 2000, killing all of its occupants.
