I guess there are two things. If there has been any lack of clarity about this, let me very clear about it right now. When we get a complaint or a notification of some sort of incident where there may be a safety defect, we take it very seriously and we act very quickly on it.
What I was saying, however, was that in trying to identify the solution, you not only, in this case, were trying to identify what it was but were applying various remedies to it, to say that you'd actually isolated what that problem was, that there wasn't something else hiding behind it.
That was the process of the engineering that we were doing: trying to understand that, well, we've found one thing that causes this problem, is that the only condition that's here? Because if we acted only that basis, that would have been a mistake for us and for our customers and Transport Canada.
