RIO DE JANEIRO – Brazil's Air Force says the black box recovered from the wreckage of the plane crash that killed a presidential candidate does not contain a recording of the flight.
The Air Force says the black box contains two hours of recordings, but not from Wednesday's fatal flight, which killed Socialist candidate Eduardo Campos and six others. It says the reason behind the discrepancy will be investigated.
Friday's statement emphasizes that the lack of recordings doesn't doom efforts to find the causes of the accident, saying the black box represents "just one element" of the investigation.
The crash threw Brazil's presidential race into turmoil less than two months ahead of the Oct. 4 race. Campos was polling in third place, behind incumbent President Dilma Rousseff.
