Not far from Congonhas Airport, a Sao Paulo neighborhood is in flames. It's a scene of devastation caused by TAM Airlines Flight 3054, a plane that crashed just seconds after takeoff in July 2007. With a shocked nation watching, investigators from the Brazilian Air Force join forces with the National Transportation Safety Board to learn what happened. After combing through more than a hundred parameters in search of a lead, they determine a series of malfunctions caused the accident, coupled with a mechanical failure so rare that pilots had received no training for it.
