During the Concorde's takeoff run, it ran over this piece of debris, cutting a tyre and sending a large chunk of tyre debris (4.5 kilograms or 9.9 pounds) into the underside of the aircraft's wing at an estimated speed of 140 metres per second (310 mph).[10] Although it did not directly puncture any of the fuel tanks, it sent out a pressure shockwave that ruptured the number-five fuel tank at the weakest point, just above the undercarriage. Leaking fuel gushing out from the bottom of the wing was most likely ignited by an electric arc in the landing gear bay (debris cutting the landing gear wire) or through contact with hot parts of the engine. Engines one and two both surged and lost all power, but engine one slowly recovered over the next few seconds. A large plume of flame developed; the flight engineer then shut down engine two in response to a fire warning and the captain's command.
