Read this: I still think it's autopilot +/- training issue instigated by this faulty stall avoidance system. Either way Boeing designed and built a faulty plane and/or provided faulty training. Boeing is at fault in some way. You cannot have two planes that just dropped out of the sky in the same way killing 346 people and the manufacturer completely escapes fault. How much responsibility can be pinned on Boeing is going to depend on its PR and its "backward dealing" ability. How much responsibility should be pinned on Boeing is going to depend on the results of the investigation which I hope will be fully revealed to the public.
