Air New Zealand will say sorry to the families of those killed in the Erebus disaster as part of the 30th anniversary commemorations. The apology will be the first to families of the 257 people who died when the airline's DC-10 crashed into Mt Erebus in Antarctica on November 28, 1979, during a sightseeing flight. It is understood chief executive Rob Fyfe will use the unveiling of a sculpture at the airline's head office in Auckland next Friday to apologise for the way the families were treated after the accident. But he would not go as far as apologising for the accident itself or the subsequent controversial investigations.
