Regarding the current accident I'm not sure why you are so gung ho to hang the (convienently dead) crew? Human factors might well come into play ultimately but I guess that's what makes S P E C L U A T I O N interesting.
I've got to agree with Humble. Something was obviously VERY not right. There was nothing unimaginable here, no freak storm. These were relatively normal conditions. As was indicated, the flaps should NOT have been deployed. I understand the statement that the last mistake may not have been the root cause of the accident, but it's obviously a MAJOR speed-bump and the deciding factor in whether you end up on a runway or in the ground.
I'll admit, I've never flown through icing (We just don't have it here in the tropics) but there are other major concerns we have. We have an active volcano I have flown near which has it's own complications. We have nasty winds. Not ice, no, but the point is, we have dangers here, and we have procedures to remain safe while flying in that environment. And if a plane crashes as a result of failing to follow procedure, then it IS pilot error. Now, if all we are looking for is something to point the finger at, we have it. But if we want to avoid this happening again, then we do need to dig deeper and find other things that could have complicated the situation, things that CAN be rectified. But as far as the ultimate cause, it sounds like pilot error.
