Why is the reporting process so important? Is it the case that one single report can highlight something more critical?

Certainly, what we've seen with the AIB, we get to see these mandatory occurrence reports that potentially could fall into a serious incident or accident category.

And there have been occasions where we've actually seen these reports come in and decided to actually do an investigation.

Again, the whole idea of an investigation that the AIB carries out is not to apportion blame and liability, it's to learn the lessons and then put in place actions to prevent recurrence, which in most cases is a safety recommendation, although we do work with those involved to encourage them to do safety action prior to us issuing the safety recommendations.

So we've certainly done that.

We also use the MORs as a way of looking at whether something we're looking at has been reported previously and what sort of actions were taken as a result of those.

So a sort of reverse trend analysis, I suppose, in that an event has occurred and we're now looking back to see whether there were some precursors that could have identified that.

And we share that around the world as we talk to people.
