OC,
Thanks for your response.
One can say that Air France should have expedited the replacement of the pitot tubes and this accident wouldn't have happened. This would be hindsight given that non of the incidents had led to anything resembling AF447. A situation existed which needed change but one could argue that this accident could not have been anticipated.
Your quote is exactly what I meant by hindsight. I limited my post only to the pitot tube situation, leaving what the AF447 crew did or didn't do up to those have flown or presently fly commercial jet aircraft.
