Search and rescue operations were dispatched and soon confirmed the worst fears: wreckage was spotted on Ross Island, on the lower slopes of Mt Erebus and it was clear there'd been no survivors. "That same accident would not happen on a modern airliner," Captain Andrew Ridling, head of the New Zealand Air Line Pilots Association, told the BBC. In part, that's because of lessons learned from crashes like the one of TE901. "The equipment today is extremely good. You've got a satellite based navigation system, so being on the wrong flight path like that would just not be possible."
