The facts have been put forward many times on this and other threads on this subject.
What it boils down to is there are those who think it is acceptable to completely disregard Company standing orders, CAA directions, and blat around at 1,500 ft in excess of 250kts, in a DC10 loaded with passengers, in conditions that are known can be hostile on your very first trip to the area, and make statements like "We may have to pop down here to 1,500ft here, I think, and the first officer replies "Probably see further in anyway."
Those that think whiteout obscured Mt Erebus at all times during the descent from 16,000ft, as it was never sighted at any time. Those that think going past Beaufort Island on the wrong side and not noticing is acceptable, then no amount of discussion, and fact, is going to change there beliefs, obviously.
