Suggest that anyone who is interested gets hold of a copy of, and reads, the report. ANZ (and I knew some of the investigators) put a lot of work into the investigation and the reports highlighted a number of tech problems with ILS technology which the tech-o community were aware of .. but the fliers .. not aware.
While it is often easy in hindsight to see the clues, at the time everything is quite dynamic and nowhere near as straightforward.
However, a very useful and educational incident to read up on ...
One thing which impressed me was the level of company support given to the crew .. ANZ had a good approach to "just culture" when it came to investigations.
