Air France Flight 4590


Air France Flight 4590 was a Concorde flight from Charles de Gaulle International Airport near Paris, France, to John F. Kennedy International Airport in New York City, New York, and operated by Air France. On 25 July 2000 it crashed in Gonesse, France. All one hundred passengers and nine crew on board the flight, and four people on the ground, were killed.
The flight was chartered by German company Peter Deilmann Cruises and all passengers were on their way to board the MS Deutschland cruise ship in New York City for a 16-day cruise to South America. During the plane's take-off run from Charles de Gaulle Airport, a piece of titanium debris on the runway ruptured a tyre which subsequently burst. The debris was about three centimetres wide and 43 centimetres long. A large chunk of tyre (4.5 kg) struck the underside of the aircraft's wing structure at well over 300 km/h rupturing fuel tank number five above the landing gear. Leaking fuel was ignited by an electric arc in the landing gear bay or through contact with severed electrical cables. At the point of ignition, engines one and two both surged and lost all power, but 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.
Having passed V1 speed, the crew continued the take-off but they could not gain enough airspeed on the three remaining engines, because the undercarriage could not be retracted. The aircraft was unable to climb or accelerate, and it maintained a speed of 200 knots (370 km/h) at an altitude of 200 feet (60 m). The fire caused damage to the port wing. Engine one surged again but this time failed to recover. Due to the asymmetric thrust, the starboard wing lifted, banking the aircraft to over 100 degrees. The crew reduced the power on engines three and four to attempt to level the aircraft but with falling airspeed they lost control, crashing into the Hôtelissimo Les Relais Bleus Hotel near the airport
