The Concorde was a technological marval. When Charles Lindbergh flew across the Atlantic Ocean for the first time in 1927, it took him more than thirty hours. A Concorde could make the same journey in under four hours. But it wasn't cheap. In 2002, a seat on aConcorde flight from New York to London cost over US$6,300.But for that, you got to travel at twice the speed of sound,18,288 metres above the ground. Only as tronauts fly higher.
