creation of the false McMurdo waypoint and how it came to be changed
without the knowledge of Captain Collins".

In paragraph 229 it is said that submissions had been put to the
Commissioner that "the shifting of the McMurdo waypoint was done
deliberately so as to conform" with a track used by military aircraft
proceeding to Williams Field. Then in paragraph 230 there is a summary
of contrary arguments advanced by members of the navigation section to
support their claim of accident. They include--

"(c) It was pointed out that if the McMurdo waypoint had been
intentionally moved 25 miles to the west, then the flight plan
would have a corresponding change to the track and distance
information which it previously contained. Instead of a true
heading from Cape Hallett to the NDB of 188.9° and a distance of
337 nautical miles, there would have been required, in respect of
the changed McMurdo waypoint, a true heading of 191° and 343
nautical miles. Similar alterations would have had to be made in
respect of a return journey to the true north."

That is the matter already outlined. Concerning it the Commissioner said
in paragraph 234 that there was "considerable validity in this point"
although then he added:

"... the Navigation Section may have thought it not necessary to
alter the track and distance criteria from Cape Hallett to McMurdo
for the reason that the pilots were accustomed to flying on Heading
Select down this sector and not by reference to the fixed heading
programmed into the AINS."
