Bletchley , you asked :

quote : When this sort of major failure is detected what do the wider International authorities do (or can do) to put things right?

This has been the real issue in fact. Investigations Offices, and / or ICAO are publishing reports and recommendations. But it is up to the States authorities to implement those recommendations.
Very often , in a lot of cultures ( and in our case in Linate, the Latin culture is a good example ) acting on the recommendations is seen as an admission that something was wrong before, in areas where the same people having the power to act were responsible. Therefore they try to make the accident a human error and by blaming individuals they think they can avoid blame on areas for which they were in charge.
The only way out of this paradox is to get away from the " blame game " and enter the area of " just culture " where people making errors (or even mistakes) can report them in a non-punitive way , and actions to prevent thoses mistakes from happenning again are seen as an improvement , or a " good " thing to do, having a positive impact on one's carreer.
Only very few States have put such a system in place , Denmark for instance is one of them, if not the only one ,at the moment.
But we are working on doing someting similar in many States right now.
But what is happenning in Milan at the moment is setting the clock back further, as the start of any "just culture " system is based on TRUST.
