We investigate when there is an accident. When we look at the facts of a particular accident and determine what we have the most to learn, then we will do a full investigation. And all of the facts we find in that investigation are made public. I think it's proactive in the sense that if you've learned these lessons and you've made a recommendation, what we are saying is that this is what needs to be fixed so you don't have another accident.
