Certainly, what we're talking about here is obviously a sensational issue in the news, a very acute risk in the whole thing and a one-off. What we're talking about is.... Of course no one approves of anyone operating impaired, and impairment relates to a whole number of issues, not just the ones you discussed there. Obviously, you can talk about alcohol, you can talk about drugs, you can talk about distractions, and you can talk about fatigue. Those are all cited by the NTSB as forms of impairment.
Again, we're very encouraged by the Minister's response in the pilot “fit to fly” workshop. We think that's a very proactive approach. At Air Canada, and I know at other carriers, we have a very extensive employee assistance program, which is very—again—proactive in mitigating these risks before they happen, so you don't have an instance like the one you discussed earlier.
On top of that, though, if we're going to talk about impairment, if we're going to talk about the elephant in the room, we're talking about fatigue. This is a pervasive risk that affects the entire industry and is completely unaddressed.
