Was terrorism behind the Air France crash?

Why did DGSE agents release potentially “doubtful” information ten days into an investigation when they could have waited only a few more hours to verify facts? Before this information was released, terrorism as a cause for the crash was at the bottom of most experts’ guess lists. Investigators had been focusing on mechanical failure, namely faulty speed sensors, as well as lighting strikes. Satellite photographs suggest that the aircraft flew into a violent storm. At first there was no crash site, which only enhanced the mystery. Then the site was found. Headway was being made. Why bring terrorism into the mix so late in the game, only to say excusez-moi, our mistake?
