Investigators looking into the crash of an Airbus A320 in the French Alps on Tuesday have been able to extract a usable audio recording from a black box recovered on the site, France's aviation security investigator BEA said. "We just have been able to extract a useable audio data file," Remi Jouty told a news conference, adding that it was too early to draw any conclusions about the causes of the crash.
