If we look at the watchlist, we have it set up in a problem and solution format, and you'll see the solutions we are suggesting in terms of the data.
Just to show you this briefly, in the marine sector, voyage data recorders are required for international voyages. They are not legally required for domestic voyages, although some ferry operators have fitted their ships with SVDRs, simplified voyage data recorders
In the rail sector, we see a move to have crashworthy and fire-resistant recorders, but not for existing locomotives. They're only going to be fitted on new locomotives. As you probably know, locomotives last an awfully long time, so we're looking at 15 to 20 years out before the fleet is fitted with something that was recommended some time ago.
What happens in this area is that it's technology-driven, and by the time the industry takes up these measures and incorporates something they would call a “new measure”, there's already second-, third-, fourth-generation technology available that's much better. So there's this lag, and we don't always have the best data. In rail, for instance, we don't have voice recorders.
