French officials investigating the Air Algerie flight that crashed in Mali killing all 116 passengers on board confirmed on Thursday that the cockpit voice recorder was not usable.
The black boxes from the Air Algérie plane that crashed in the Malian desert on Thursday arrived in Paris on Monday. But ministers warned that the investigation would take a while.
French flags flew at half-mast on Monday to mourn the 118 victims of the Air Algérie airplane tragedy. The black boxes from the crash will be handed over to the French authorities today.
