Yes, sir. As a matter of fact, the cooperation between the U.S. and Canada is in place, and we see it frequently, especially if you look at the Great Lakes. The prosecution of SAR incidents will take place using Canadian assets on the American side of the border, and vice versa. In Alaska there is a rescue coordinating centre in Anchorage and they coordinate with our rescue coordinating centres to prosecute cases. They have a SAR capability in their national guard and their coast guard and they would be able to respond to any incident that occurred in Canada. We have, through the same arrangements, the ability to very quickly go across the border and work in Alaska. That happens pretty frequently as well. So there is a good, high level of cooperation between the U.S. and Canada.
For a number of years we've also had Russia involved in a three-nation Arctic SAR program. We did an annual search and rescue exercise. Again, it's all about the agreement and cooperation, so we have the ability to speak with the Russian RCCs, from our RCCs, and to be able to communicate and pass data.
So there's an international capability resident out there, and that happens at the rescue coordinating centres of the various nations. There are a lot of common procedures, so it facilitates our ability to be able to operate internationally.
