From London’s Heathrow Airport and Orly Airport outside Paris,
the first Concordes with commercial passengers simultaneously
take flight on January 21, 1976. The London flight was headed to
Bahrain in the Persian Gulf, and the Paris to Rio de Janeiro via
Senegal in West Africa. At their cruising speeds, the innovative Concordes flew well over the sound barrier at 1,350 miles an
hour, cutting air travel time by more than half.
