Whilst what you state may be true and factual, for me the most important reason is why.
Facts do not help the aviation industry to improve safety. "Someone should have done this or that" is not that important, it's already known. Why didn't they pursue the correct course of action? Why did they think everything was according to plan when it was not? Why did they miss a critical indication? Why, why why?
idle bystander
Do you really think that the system designer is solely responsible for certifying an aircraft or system? Do you seriously think that safety assements, FHAs, FMECAs, HF testing, pilot cockpit working group decisions, FAA auditing, plus a multitude of other operational and safety justifications did not go into the design of the NG?
