Tragedies, Aviation: "Exhibit 164" was a photocopied diagram of McMurdo Sound showing a southbound flight path passing west of Ross Island and a northbound path passing the island on the east. The diagram did not extend sufficiently far south to show where, how, or even if they joined, and left the two paths disconnected. Evidence had been given to the effect that the diagram had been included in the flight crew's briefing documentation. Legacy of the disaster The crash of Flight 901 is one of New Zealand's three deadliest disasters – the others being the 1874 Cospatrick sailing ship disaster in which 470John Wilson, The voyage out – Fire on the Cospatrick , from Te Ara: The Encyclopedia of New Zealand.

At the time of the disaster, it was the -deadliest air crash of all time. , the crash remains Air New Zealand's deadliest accident, as well as New Zealand's deadliest peacetime disaster (excluding the Cospatrick sailing ship disaster, which happened en route to Auckland). Flight 901, in conjunction with the crash of American Airlines Flight 191 in Chicago six months earlier (25 May), severely hurt the reputation of the McDonnell Douglas DC-10. Following the Chicago crash, the FAA withdrew the DC-10's type certificate on 6 June, which grounded all U.S.-registered DC-10s and forbade any foreign government that had a bilateral agreement with the United States regarding aircraft certifications from flying their DC-10s, which included Air New Zealand's seven DC-10s. The Air New Zealand DC-10 fleet was grounded until the FAA measures were rescinded five weeks later, on 13 July, after all carriers had completed modifications that responded to issues discovered from the American Airlines Flight 191 incident. Flight 901 was the third-deadliest accident involving a DC-10, following Turkish Airlines Flight 981 and American Airlines Flight 191. The event marked the beginning of the end for Air New Zealand's DC-10 fleet, although talk existed before the accident of replacing the aircraft; DC-10s were replaced by Boeing 747s from mid-1981, and the last Air New Zealand DC-10 flew in December 1982. The occurrence also spelled the end of commercially operated Antarctic sightseeing flights – Air New Zealand cancelled all its Antarctic flights after Flight 901, and Qantas suspended its Antarctic flights in February 1980, only returning on a limited basis again in 1994.
