Cover-up? Plane crash that killed Brazilian presidential socialist candidate had black box that 'recorded data of different flight'

The black box recovered from the wreckage of the plane crash that killed Brazilian presidential candidate Eduardo Campos did not record his flight, Brazilian Air Force (FAB) says. It said the audio recording FAB experts had analysed was not related to the flight that crashed on Wednesday. A spokesman said they were trying to determine what the recording was. Mr Campos and six others died when his private jet crashed in bad weather in the port city of Santos near Sao Paulo. Experts from the Centre of Investigation and Prevention of Aeronautical Accidents in the Brazilian capital, Brasilia, have been trying to reconstruct the audio files from the black box in search for more clues as to what happened in the lead up to the accident. "The two hours of audio, the maximum recording capacity of the equipment, which were received and validated by certified technicians, were not of the flight of 13 August," air force spokesman Pedro Luis Farcic said in a statement (in Portuguese). "It is not yet possible to determine the date of the dialogue recorded in the CVR (Cockpit Voice Recorder), given that this equipment does not record this information," he continued, adding that an investigation would determine what may have happened.
