I'll just make a quick correction, because we at the Transportation Safety Board do not talk about the fault of the operator.
When there's an interface between man and machine, we try to figure out why an individual did what they did so that we can understand the whole context of the accident. But I don't really think that's the point. I think the point is action in terms of the lessons that we've learned from our investigations.
If you look at the uptake on the recommendations, we rate the response to 67% of our recommendations as fully satisfactory. For most of the remainder, there's agreement with the regulator that this is a safety issue and that this needs to be done. What happens is, from there to implementation it takes far too long.
