Boom! BOOM! That was the incredible double sonic boom of the majestic Concorde supersonic aircraft breaking the sound barrier. If it came in low as you watched in awe, the noise would make your bones rattle. The Concorde was perhaps the sexiest, most exciting airplane in the history of aviation. It was a joint venture between British Airways and Air France that had its maiden voyage in 1969 but began commercial service in 1976. After a crash in 2000 in Paris, traveler interest in the plane began to diminish and in April of 2003, both airlines announced they would discontinue service.
