I want to know the answer to the following question:
When did an Air New Zealand crash on Mount Erebus?
All the background I'm provided with is that "Antarctic sightseeing flights (which did not land) operated out of Australia and New Zealand until the fatal crash of Air New Zealand Flight 901 in 1979 on Mount Erebus, which killed all 257 aboard.". Is that enough to answer the question?
Answer: yes
