Mount Erebus
257: On November 28, 1979, Air New Zealand Flight 901, an Antarctic sightseeing flight, collided with Mount Erebus on Ross Island, Antarctica, killing all 237 passengers and 20 crew on board. The flight crew had not been informed that the computer coordinates for the flight path of the McDonnell Douglas DC-10-30 had been changed the night before, directing the flight directly into Mount Erebus rather than the usual path down McMurdo Sound.
