Mount Erebus
The Mount Erebus disaster occurred on 28 November 1979 when Air New Zealand Flight 901 (TE-901) flew into Mount Erebus on Ross Island, Antarctica, killing all 237 passengers and 20 crew on board. Air New Zealand had been operating scheduled Antarctic sightseeing flights since 1977. This flight was supposed to leave Auckland Airport in the morning and spend a few hours flying over the Antarctic continent, before returning to Auckland in the evening via Christchurch.
