It remains New Zealand's worst peacetime disaster. On 28 November 1979, a sightseeing aircraft carrying 257 people crashed 
head-on into the side of a volcano in Antarctica.

The tragedy of flight TE901 was a shock for New Zealand, affecting almost everyone in the country in some way, and led to 
years of investigations and a bitter blame game.

And the legacy of the Mt Erebus disaster is still felt 40 years on.
