VERSAILLES - A French court cleared Continental Airlines of any crime over the July 2000 crash of an Air France Concorde but upheld a ruling that the US airline bore civil responsibility for the disaster. The US airline had been convicted of involuntary homicide in 2010 on the basis of expert testimony that the crash of the supersonic jet was caused by a piece of metal that fell from one of its planes on to the runway at Paris’ Charles de Gaulle airport. The conviction and an associated 200k-euro fine were overturned on appeal, as was the conviction for criminal negligence of the Continental engineer whose maintenance work had been blamed for the strip of metal falling off a DC10 airliner.
