 Was it last year that there was the tsunami that hit the Hawaiian Islands or the year before? And they had warnings for several hours about that, and in the end it was not actually that big. But that people could have that warning is incredibly important. Early warning systems are critical, aren't they, James? Oh, absolutely. And one of the things that's been really good, I think, is that you've seen those systems now beginning to be installed in poorer countries and making sure that you've got the capacity for people to be protected there as well.
