THH:
3 pilot ops should have prevented this, single pilot ops should have coped, but if we refuse to consider the environment that this accident happened in then we've learned nothing from the past!
In most airlines your comment is correct. Not in this environment. The F/O sitting on the jumpseat was not about to open his mouth with two captains sitting up front. Read the accident reports for KAL (Guam and Stansted). In both cases the F/O and F/E knew things were not right and sat there and let the captain kill them. That is the culture you are dealing with. Nothing has changed. As we used to say, "Lose your life but don't lose face". Korean F/O's don't correct Korean Captains. I will bet the F/O's voice is not on the Cockpit Voice Recorder.
