Known forRoyal Commission of Inquiry into the crash of Air New Zealand Flight 901

Peter Thomas Mahon QC (1 November 1923 – 11 August 1986) was a New Zealand High Court judge. He led a one-man Royal Commission of Inquiry into the 1979 crash of Air New Zealand Flight 901 into Mount Erebus. Contradicting the previously issued official report, his inquiry determined that the flight crew was not at fault and instead "incompetent administrative procedures" within Air New Zealand were to blame. Mahon famously and controversially concluded that the airline's witnesses presented "an orchestrated litany of lies" in their responses to the inquiry.
