That said, and repeating for clarification, the problems with the Thales AA pitot tubes are listed as a contributing factor to the accident in the BEA report.
I think they have a role more than contributing in the accident
In fact they are the trigger of the accident
If the probes were not blocked .. the accident not have occurred .. Bonin and other pilots of AF447 would have continued a quiet career at Air France .. . and the passengers will be there to celebrate the new year 2013
