S01E01 Crash of the Concorde: Air France Flight 4590

January 7, 2013 | By | Comments More

For over twenty years, the Concorde was the fastest and safest airliner in the world. However, on July 25, 2000, it’s perfect record was marred when a Concorde flight crashed after takeoff, killing all 109 people on board, and 4 people on the ground. Through CGI analysis and gripping eyewitness testimony, “Crash of the Concorde” investigates that last fateful trip, deconstructing the tragedy second-by-second.


Air France Flight 4590 was a Concorde flight operated by Air France which was scheduled to fly from Charles de Gaulle International Airport near Paris, to John F. Kennedy International Airport in New York City. On 25 July 2000, it crashed into a hotel in Gonesse, France. All one hundred passengers and nine crew members on board the flight died. On the ground, four people were killed and one left with serious injuries.

The flight was chartered by German company Peter Deilmann Cruises. All passengers were on their way to board the cruise ship MS Deutschland in New York City for a 16-day cruise to Manta, Ecuador.

This was the only Concorde accident in which fatalities occurred. It was the beginning of the end for Concorde as an airliner; the type was retired three years later. The accident was a hull loss, and the aircraft involved was one of the only 2 Concorde aircraft to be scrapped.


Post-accident investigation revealed that the aircraft was just at, if not exceeding, maximum takeoff weight for ambient temperature and other conditions, and up to one ton over maximum structural weight. As it left the gate, it was loaded such that the centre of gravity was excessively aft. Fuel transfer during taxi may have overfilled the number five wing tank. A twelve inch spacer that keeps the left main landing gear in alignment had not been replaced after recent maintenance, though the 2002 French Bureau Enquetes-Accidents investigation concluded that this did not contribute to the accident. The wind at the airport was light and variable that day, and was reported to the cockpit crew as an eight knot tailwind as they lined up on runway 26R. Over an hour delayed, the crew proceeded with take-off.

Five minutes before that decision, a Continental Airlines DC-10 departing for Newark, New Jersey, had lost a titanium alloy strip, 435 millimetres (17.1 in) long and about 29 to 34 millimetres (1.1 to 1.3 in) wide, during takeoff from the same runway. French authorities have acknowledged that a required runway inspection was not completed after the Continental takeoff, as was protocol for Concorde takeoff preparation.

During the Concorde’s subsequent take-off run, this piece of debris, still lying on the runway, cut a tyre, rupturing it. The sudden disruption of the centripetal force holding the tyre together sent debris flying about. A large chunk of this debris (4.5 kilograms or 9.9 pounds) struck the underside of the aircraft’s wing structure at an estimated speed of 500 kilometres per hour (310 mph). Although it did not directly puncture any of the fuel tanks, it sent out a pressure shockwave that eventually 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 to have been 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 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.

The crew was trying to divert to nearby Le Bourget Airport, but accident investigators stated that a safe landing, given the aircraft’s flight path, would have been highly unlikely.
