PapaHotel6, goodday Ace. I'll take my lead from Gordon Vette when he said, "When I flew visually in the Antarctic I believed that there was no problem. Prior to my research on the Antarctic crash, I would have scoffed at this requirement. I am now firmly convinced that under certain lighting conditions an aircrew could fly into terrain, even with the terrain in the field of view and with plenty of time to take avoiding action. Therefore descent below the top of Mount Erebus, or other polar terrain, even in clear conditions, is hazardous. It appears to me that those of us who conducted the Antarctic flights may unwittingly have exposed ourselves, our passengers and crew, to a similar danger".
I don't have the arrogance to presume that I would not have been suckered given ANZ modus operandi.
Answer the question, why do QF scenic flight remain at the MSA. Because Collins screwed up, or because the entire enterprise of operating below the MSA was moronic? There can only be one answer.
