What a surprise that this is getting out of shape.
If at any time, on any subject, your beliefs are in the extreme.....you are probably motivated by emotion, or mentally ill.
Yes ANZ should have contacted the crew and told them of the co-ordinate change.
Yes they should have put someone on the flightdeck who had Antarctic flying experience.
And yes, they lost the plot after the event.
Yes the crew decended below the altitude that they were legally allowed to be flying at (regardless of whether they were VMC or not)
And yes, the buck stops with the PIC.
Both sides of this argument are still focussing on laying the blame.
The focus needs to be on what can be learnt.
I think the lessons have been learnt, if someone offered me a flight down there tomorrow on ANZ I would accept in a flash.
