Detailing the events of 25 July, 2000, when Air France Concored Flight 4590 crashed shortly after taking off from Charles de Gaulle Airport, Paris, resulting in the deaths of 113 people. Most of the wreckage was consumed by fire, but three mysterious clues were found on the runway - a ruptured fuel tank, some torn pieces of tyre, and a mysterious strip of metal. This documentary reveals how French investigators used this curious collection of clues to determine the cause. This was the first-ever fatal accident involving a Concorde, the world's only supersonic passenger airliner, but nevertheless led to an immediate cessation of the aircraft's use and ultimately contributed to its withdrawal from service almost four years later.
