But although the bag was empty it was suggested at the hearing that while at McMurdo Captain Gemmell might have "collected a quantity of documents from the crash site and brought them back to Auckland"; that only three of the flight documents carried on the aircraft had been produced to the Royal Commission; that it was "curious" to find that each favoured the case "which the airline was now attempting to advance"; and all this against counsel's theory that before Captain Gemmell had left Auckland on 29th November he was aware of possible problems associated with the amendment to the destination point co-ordinates. Captain Gemmell flatly denied having that knowledge while in the Antarctic; and he rejected totally any suggestion that he had recovered anything from the site which had not been passed across in terms of Mr Chippindale's instructions. In that regard he answered two propositions put to him by the Commissioner (at page 1834) in the following way: "Well the suggestion may be made to me in due course that because of the discovery that Capt Collins did not know of the alteration in the nav track consequently someone in the co. would have been instructed to locate whatever documents there were on the crash site and elsewhere that might throw light on that question. You say that no such instruction was given to you.... Certainly not. But it would have been a reasonable instruction would it not.... No it would not have." Intimidation of a Witness At this point it is necessary to mention a different suggestion which was also rejected by Captain Gemmell. It was put to him during cross-examination that he had carried back from McMurdo a blue plastic envelope containing personal property recovered from the accident site. In evidence given later by First Officer Rhodes the envelope was supposed to have been entrusted to Captain Gemmell by Mr Chippindale for delivery in New Zealand since Captain Gemmell was about to depart from the base several days before the others. First Officer Rhodes had himself been in Antarctica as a member of Mr Chippindale's investigation team, representing there the Airline Pilots Association. He appeared as a witness before the Royal Commission on two occasions. During his first appearance he was called by the Association. He did not refer then to a blue envelope; but because it was thought that the material may have been mentioned by him to the Association's counsel he was recalled to give evidence, this time by counsel for the airline.
