In November 1962, the British and French governments announced a deal that caused great distress in the boardrooms of American planemakers. The two countries announced plans to jointly build a new airliner, one that would be able to fly at more than twice the speed of sound. The aircraft - to be called 'Concorde' - would be the most advanced civilian aircraft in the world.
But America would create its own rivals to the European design, building a giant, passenger-carrying jet capable of flying faster than a rifle bullet. So what happened to the US plans to master supersonic passenger flight?
