So, maybe it should be in the "History" Section, but here goes:

CONCORDE TAKES OFF:
January 21, 1976


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.
