  • On 25 July 2000, Air France Flight 4590, a Concorde passenger jet on an international charter flight from Paris to New York, crashed shortly after takeoff, killing all 109 people on board and four on the ground. It was the only fatal Concorde accident during its 27-year operational history. 16:38 CEST (14:38 UTC), five minutes before the Concorde departed, Continental Airlines Flight 55, a McDonnell Douglas DC-10-30, took off from the same runway for Newark International Airport and lost a titanium alloy strip that was part of the engine cowl, identified as a wear strip about 435 millimetres (17.1 in) long, 29 to 34 millimetres (1.1 to 1.3 in) wide, and 1.4 millimetres (0.055 in) thick. The DC-10 did not crash or malfunction later.[3]: 17, 107 [7] At 16:42, the Concorde ran over this piece of debris during its take-off run while the aircraft was doing 185 mph (300 km/h), cutting the right-front tyre (tyre No 2) of its left main wheel bogie and sending a large chunk of tyre debris (4.5 kilograms or 9.9 pounds) into the underside of the left wing at an estimated speed of 140 metres per second (270 kn; 500 km/h; 310 mph).[3]: 115  It did not directly puncture any of the fuel tanks, but it sent out a pressure shockwave that ruptured the number 5 fuel tank at its weakest point, just ahead of the left landing gear well. Leaking fuel gushing out from the bottom of the wing was most likely ignited either by an electric arc in the landing gear bay (debris cutting the landing gear wire) or through contact with hot parts of the engine.[3]: 120-123  Engines 1 and 2 both surged and lost all power, likely due to ingestion of hot gases (both engines) and tyre debris (engine 1 only), and then engine 1 slowly recovered over the next few seconds.[3]: 17  A large plume of flame developed, and the flight engineer shut down engine 2 in response to a fire warning and the captain's command.
