Perhaps this is a question best put to your executive members here. Is there a move afoot in transportation safety worldwide now or is it a de facto happening that there is already now a move towards a standardization of regulatory standards? You would be looking, as a minimum threshold, for example, at a standard recommended by the Australian transportation safety board, the United States transportation safety board, etc. Is there an emerging, kind of international level or standard now across the system?
We're talking about fewer and fewer manufacturers of planes, trains, double-hulled ships, and so on. Isn't there an emerging international standard or set of standards?
