Not joking: Not a single solitary pilot said "Capt. Wilson told us that the nav track went to X", X being a position other than at McMurdo Station.
The point re the contradiction is that it was one that was brought to the captain's notice the night before (assuming that he was told that the nav track was to McMurdo Station).
So it all depends on what was presented at the briefing. If it was "the nav track is to McMurdo Station", then it must be an error. If it was "the nav track is to some penguin colony by the Dailey Islands", then it's not an error.
But there is no evidence to support the proposition that the pilots were told that the track went to a point near the Dailey Islands. Nothing at all - from either side.
