Then let's get back to the facts:
Only two previous flights had similar conditions. Captain Dalziel took the alternative route. Captain Ruffell did not, but he baled out once he got the weather report, and toured the Dry Valleys - with good success.
Captain Collins had blue skies in the Dry Valleys, but he "preferred [McMurdo] first". Why? So he himself could see the various shacks, which he had not seen before. So this gentleman went and did something that could only be justified in a single-seater, and pretended to be visual, when he knew he was not.
This whole argument is insane, and the root cause of it is a judge with a brain tumour and a couple of dodgy lawyers.
