My family and I were within a hair's breadth of being on that flight and hearing the sad news that evening on a TV in Tauranga shook us to the core.
The arguments will continue, but in my book the crew were in error. If they were in true "visual" conditions they should have seen the dangers; it's no good arguing about waypoints being moved. They were ultimately responsible for the safety of the aeroplane and it went pear-shaped. Sorry if that upsets anyone... 30+ years later I still get the shivers thinking about it.
