How can anyone read that transcipt, or even the Chippendale version, without two things being blindingly obvious?
1) The crew thought they were no-where near Erebus, obviously based on there nav equipment and the infamous changed waypoint (The Captain even re-engages the nav system, obviously because he is confident his position re it's readout.)
2) The crew believed they were in VMC, albeit marginal. As was established, sector whiteout fooled them into thinking they were looking at a clear sky, and a descent in VMC is just fine as long as terrain clearence can be visualy maintained.
Did the original report even cover the changed nav co-ordinates? If not, what was the subsequent "Official" reason for ANZ not revealing this fact, and why did they think the crew got their position so wrong?
