By the way, this tragedy has interesting backround that is clearly seen from Russia. CAA of Russia uses this crash and the fact that FO was graduate of non-state-owned flight school to finish off all "bad" pilots( everyone except those who graduated CAA-owned flight schools ). I think constant pressure experienced by first officer who was one of potential victims of this CAA's on-going rampage contributed to human error, if one took place. Just remember Andreas Lubitz who feared to lose his licence. Meanwhile, russian CAA is already working on new massive list of pilot licenses to be revoked.
