The 50th Anniversary of the first BAC-Aerospatiale Concorde flight was on March 2, 2019. Concorde 001 made its first test flight from Toulouse on March 2, 1969.
Scheduled flights began on January 21, 1976 on the London–Bahrain and Paris–Rio de Janeiro (via Dakar) routes, with BA flights using the Speedbird Concorde call sign to notify air traffic control of the aircraft’s unique abilities and restrictions, but the French using their normal call signs. The Paris-Caracas route (via Azores) began on April 10. The US Congress had just banned Concorde landings in the US, mainly due to citizen protest over sonic booms, preventing launch on the coveted North Atlantic routes. The US Secretary of Transportation, William Coleman, gave permission for Concorde service to Washington Dulles International Airport, and Air France and British Airways simultaneously began a thrice-weekly service to Dulles on May 24, 1976.
Of the twenty aircraft built, 18 are still intact and in museums around the world.
