THE SLIP IN ENGINEERING SAFETY THE BLACK MARK ON CONCORDE’S INVINCIBLE RECORD Source -i.pinimg.com T he evening of 25th July 2000 might have been a normal Tuesday evening for the French in Paris. But the pas- sengers on Air France Flight 4590, were a bit worried because their flight was facing a delay of one hour. Passengers on this Concorde airliner were bound to New York, starting their journey from Roissy-Charles de Gaulle Airport. The normal protocol of a Concorde flight includes a full runway inspection before the takeoff, but this was not complet- ed for this particular flight due to the flight being already late. The airliner was left in the hands of Pilot Christian Marty and his co-pilot to cruise across the Atlantic. The history of supersonic commercial air travel runs back to the 1950s and 1960s, the same period that witnessed the Cold War - American and Soviet spaceflight rivalry- that launched man into space. While the superpowers rushed to conquer outer space, Britain and France were aiming at supersonic air travel to manu- facture air crafts that could fly faster than sound. agreement. The Concorde is one of the fastest passenger vehicles ever made. It has a peak speed of 2,180 km/hr, equal to a Mach number of 2.04, which is more than twice the speed of sound. The flight has a seating capacity of 92 to 128 pas- sengers. First flown in 1969, Concorde entered service in 1976 and continued to fly for the next 27 years. It is one of the only two supersonic airliners operated commercially; the other is the Soviet-built Tupolev Tu-144, which was in operation for a much shorter period. On the eve of 25th July 2000, the ground con- trol gave permission to Air France flight 4590 to use runway 26 as requested by the crew. The flight taxied towards the runway at 4:34 p.m. (French time). In the late 1950s, the US, France, Britain, and the Soviet Union became involved in supersonic jet designing.

However, the cost of such an enormous project was overwhelm- ing for either country to be accomplish alone. As a solution, British Aerospace and France’s Aerospatiale collaborated in 1951, in the production and development of the project. This negotiation was not a commercial agreement between the two companies, but as an international treaty between the nations; the treaty which was signed in 1962.
