The Mt. Erebus disaster occurred on November 28, 1979, because the wrong coordinates were put into the planes computer navigation system. It was flying low for sightseeing purposes because it was thought to be on the correct path. The pilots could not see the mountain due to white out conditions.
There are no commercial flights near this volcano: logistical flights are never flown near Mt Erebus.
