Investigators probing the crash of an Air Algerie flight in Mali that killed 116 people last month said on Thursday they had been unable to access voice recordings from the flight deck. “The tape was a little bit damaged. We were able to extract it… The BEA laboratory was able to restore the tape. Unfortunately the recordings are so far unusable,” Remi Jouty, the head of France’s Bureau of Investigations and Analyses (BEA) air safety agency, told journalists. Flight AH5017, a McDonnell Douglas 83 jet that had taken off on 24 July from Ouagadougou in Burkina Faso bound for Algiers, crashed in the Mali desert after asking to turn back as bad weather struck.
