I don't think we're truly behind in Canada. From the regulatory perspective there are some small differences with our colleagues to the south of the border, in the United States, but some of those differences could suggest we're at pace or ahead.
In our understanding and our discussions with some of our colleagues in Europe, the United States, and elsewhere, I think industry is doing a pretty good job of trying to share information, and regulatory groups within those same jurisdictions are working pretty actively to share with each other their concerns and what they are doing. I see that as a good thing, but it's not necessarily universal. Not all states are on the same page, but certainly many of the more advanced states with which we work and deal closely are moving in similar patterns.
We're also learning from each other. That could be the operator of the air navigation system, such as Nav Canada, or it could be the regulator. I'm sure that if you ask Transport Canada you would get their view, but I think it's going quite well as far as sharing information is concerned.
