First Officer Cassin it might be thought that this item too was
immaterial. However, it is discussed by the Commissioner in the
following way.

First there is listed a series of documents "which clearly had been
carried in the flight bag of Captain Collins" and which had not been
recovered. The items comprise the New Zealand Atlas and a chart; the
briefing documents; and the ring-binder notebook. Those three items
have been mentioned. And finally a topographical map issued on the
morning of the flight. The suggested significance of these various
documents is explained by reference to the view of counsel for the
Airline Pilots Association that they "would have tended to support the
proposition that Captain Collins had relied upon the incorrect
co-ordinates" (paragraph 344).

There follows reference to the blue envelope and the matter of Captain
Eden after which paragraph 349 speaks of the flight bag:

"Then, as the Inquiry proceeded, there were other queries raised.
It seemed that Captain Collins' flight bag had been discovered on
the crash site. It was a bag in which he was known to have carried
all his flight documents. It was said to have been empty when
found, a fact which was incidentally confirmed by a mountaineer who
had seen the flight bag before Captain Gemmell arrived at the crash
site. The flight bag was rectangular, and constructed of either
hard plastic or leather, and had the name of Captain Collins
stamped on it in gold letters. It was evidently undamaged."

There is mention as well of First Officer Cassin's flight bag and the
ring-binder notebook (both of which matters have now been discussed) and
