Let's stick to the facts for a minute:
Yes, lets do that.
Weather at the McMurdo area at the time of the disaster was reported to be completely overcast at 3,500ft with other cloud layers above, and a wind of 10 knots. Mountain tops in the area were covered in cloud and although the surface visibility was good surface definition was poor and horizon definition only fair because the sun was obscured and snow surface features could not be readily identified from close up. Other aircraft in the area reported Ross Island as being completely obscured by cloud, and the crew of a helicopter which landed at Cape Bird Hut, 35 kilometres from the crash site and only an hour later, said it was overcast art 1,500ft with light snow Shortly afterwards they landed on the beach 10 kilometres from the site, in snow flurries and deteriorating conditions which made them cut short their visit.
So, here we have a helicopter crew, experienced in the area, giving up because of weather, and in the same conditions we have a DC10, 1,500ft at a minimum speed of 260kts, uncertain of there position, knowing there was a 12,000 odd foot mountain somewhere very close, even the slopes of Ross Island were above that height, and some people believe that was acceptable behaviour??
You will note no doubt, that other aircraft in the area reported Ross Island completely obscured by cloud, perhaps they were all part of a conspiracy to refute Mahon, Vette, theory of sector white out??
Oh, and finally................The hundreds of photos taken by the passengers showed the plane was flying in clear air in good weather.
And they also showed that the aircraft passed on the wrong side of Beaufort Island, and nobody noticed?? very astute navigation.
