Concorde was the fastest airliner in the world, and was considered to be the safest, as measured by passenger-deaths per passenger-mile, until 25 July 2000.
The investigation into the crash determined that a strip of titanium metal that fell onto the runway from an earlier Continental Airlines DC-10 flight punctured one of F-BTSC's tyres in the latter stages of takeoff. Chunks of shredded tyre penetrated the skin of the aircraft's wing, rupturing a loaded fuel tank. Power was lost on engine number two, and for a brief period, engine number one. A tremendous fire rapidly ensued. The aircraft was unable to climb or accelerate, and it maintained a speed of 200kt and an altitude of 200 feet. The aircraft stalled after engine number 1 lost power again. The crew was unable to control the aircraft, which crashed into a hotel just miles from the airport. The crash killed all 9 crew and 100 passengers and 4 people on the ground.
A few days after the crash, all Concordes were grounded, pending an investigation into the cause of the crash and possible remedies. (Air France F-BVFC was allowed to return home, empty but for a skeleton crew.)
The crash would force modifications to be made to the aircraft, but just before services resumed, the September 11, 2001 Terrorist Attacks took place, resulting in a marked drop off in custom and leading to the end of Concorde flights.
