French air accident investigators say that pilot errors and faulty speed and other readings led to the crash of an Air France jet over the Atlantic in 2009.
The BEA air accident investigation agency released its final report today on the crash, which killed all 228 people aboard and was the airline's deadliest accident.
Chief investigator Alain Bouillard said the two pilots at the controls never understood that the plane was in a stall and "were in a situation of near total loss of control."
The report lists a combination of "human and technical factors" behind the crash.
The BEA says it has made many safety recommendations including better training for pilots based on the Flight 447 probe.
