French investigators have released a final report into what caused the mid-Atlantic crash of a Rio-to-Paris Air France flight that killed 228 people in 2009. The report, published on Thursday by the French aviation safety authority BEA, was eagerly awaited amid a bitter row between Airbus and Air France, over who should bear responsibility. It blamed a combination of pilot error and faulty speed sensors. This was the finding of a preliminary report and also, according to a source, of a separate judicial inquiry to be released next week.
