Hello Mimpe
The AF 447 situation strikes me as one in which the incipient risks required the most experienced hand flyer right from the word go...no time for liberte,egalite,fraternite.....
Your numbers are very interesting.
But is it really a question of experience or is there more about this?
If its is only experience than this should be a constant about the history of aviation.
If its not a constant than there might be other factors like for example changed traning involved.
