OK, Dingo: Let’s go through it bit by bit – again.
“All the documentary evidence showing that the track was down McMurdo Sound”
“All”? There is only one document showing a track from Cape Hallett to a point in the middle of McMurdo Sound (ie the Byrd Reporting Point): Exhibit 164 (McFarlane p102). But the topography is barely discernable.
The RNC4 chart (McFarlane p81 ) shows a track from the west of Cape Hallett to the Byrd Reporting Point. Why would any navigator rely on that, given that you are coming from Cape Hallett, not from the west of it?
Ditto the strip chart (McFarlane p101).
“The testimony of at least 12 people … ”
All they said was that they did not know that the track went over Erebus. Not a single solitary one of them said that Capt. Wilson told them that the final waypoint was anywhere other than McMurdo Station.
If you disgagree, post the evidence. You won’t find any.
“The testimony of the pilots about a left turn.”
Where’s that bit?
"Capt. Gabriel’s testimony"
No, it’s not all in McFarlane’s book. The bit that is missing is the bit where he admits that he didn’t, actually, do any “eyeballing” at the briefing. He did it, he said, after – relying on what he remembered of the co-ordinates. Mr McFarlane decided to leave out that bit, because it didn’t suit his cause.
“Pilots discussing a left turn”?
What are you talking about? The briefing, or what happened on the Simpson / Gabriel flight?
The rest of it is just your opinion, with which I disagree.
I understand why the capitalised red type appears at the end - because you know it means an obvious case of pilot error (probably having attended several half-baked briefings in your time).
