I can add one very minor thing, Mr. McGuinty. I think, in fairness to the people at Transport Canada and other places, it's a very complex issue, and the airlines agree and acknowledge that it is. If it were an easy issue, it would have been applied a long time ago. In an area, especially in the United States, where the threat, I think, is much higher than it is here today, they're struggling with the same question. It's not an easy question, and I'd leave it up to greater minds than ours to sort it out. If it were easy, it would have been done a long time ago.
