Hi,
So the basic question of the investigation is to address the real security issues, not to find who seems "guilty" of what.
As for the level of civil responsability to be shared between the manufacturer, the company or the crew, honestly, this should be left to the court to decide
Academic blah blah
I have not to learn you the fact that the real security issues will point to some actors
And the court will point exactly the same actors with some nuances ... that's a lawyers game to be performed .. for the spectators we are
Rarely a court of justice will point responsibilities to actors not already involved in the security issues
It's granted that the pilots will take the most of the weight .. and so by consequence .. AF for many negligence
Placed on the very same situation, but with hindsight about the outcome, most pilots, including any member of AF447 crew would certainly not make the same errors
Yourself have already the verdict !
All this will be confirmed in some loooong years ... when all the smoke is settled
