Notice how 5/6 reasons the accident report contains are "crew screwed up"
That's a "you're holding it wrong" argument. There are always human factors, no matter how well trained. So while the errors these pilots made shouldn't have happened if they were better trained, at least one of the errors, fighting over who was controlling the plane w/o realizing it, is impossible in a Boeing cockpit.
These are trained pilots who did not follow their training. They didn't follow procedures that were in place for these types of events. They did not follow cockpit management procedures. They didnt know how to properly deal with stall conditions, a fundamental piloting skill. They managed to crash a airplane that was flying perfectly fine.
I don't understand the fixation on the sidestick. Its not like they just tossed it in there. Thousands of engineer hours were spent creating the systems to manage control inputs. It may have been a contributing factor, but the sidestick isn't even mentioned in the proposed improvements section. This was pilot failure.
