Well, in terms of the investment, here I would suggest not thinking solely about search and rescue and this catastrophic event that might occur. It's great to have the capability for that and that's justifiable in and of itself, but there are other things that having that kind of presence does in terms of the economic spinoffs and the northern development piece, with the support around economic development, social development, communications, telecommunications, and environmental and resource management.
Look at Royal Military College, which is one of the world's leaders, frankly, in environmental management, site reclamation, and so on. DND is at the forefront of that.
So if you look at those spinoffs and that kind of investment over a broader set of activities, it's well worth the investment. I wouldn't limit it to search and rescue.
