Let's not be too tough on the crew. They are in no position to defend themselves, not did they set out on this final journey to kill themselves and everyone else on board. Obviously.
I put the blame totally on the authorities, East and West, for allowing a system to be in place, that has lead to these types of accidents. The fact that a report will be years in the making, thus stifling valuable information for crews to learn from now, is of great concern for me.
Of course the crew will be blamed. They will take the hit for the incompetence of the authorities and the possible interference of the manufacturers.
