Thank you, sir.
First of all, let me respond to the previous question that John answered. We, the military, are the sponsor of CASARA, and we have every confidence that the membership are very skilled and very capable. What we ask them to do is not out of line. They're not doing certain things that our SAR forces are doing, understandably. What they do with their own equipment and their own time is certainly something that we have found to be very valuable. There's no issue of confidence within our rescue coordinating centres; they will, believe me, task the CASARA if that aircraft or that crew can respond more quickly. It may be not the only one, and they don't do aerial delivery, and they don't do a lot of things, but what they do is tremendously advantageous.
We try to avoid searches. For early detection we use satellite to beacon, but occasionally those measures will fail, and we end up in a search scenario. A search can be a very arduous, difficult exercise, and to have the spotters that they provide to help us search is a tremendous advantage.
