Thank you.
A couple of colleagues talked about risk assessment in terms of downturn. Can you talk to us quickly about what has changed or not changed since the downturn in the 1990s? How has the safety management system improved since the last downturn in the 1990s to now, in terms of the whole of aviation?
Second, I want to go back to a comment made earlier regarding the safety management system. I think it was left that the carriers were involved. When you have a situation in which the carriers are involved in monitoring, does that mean that we basically stay away from them? In some cases in business, we actually try to be proactive so that a potential problem doesn't become a problem by having those initiatives in place.
Could you address those two questions for me, please?
