The only thing I'd like to add is that the air force is not there alone. We support our joint colleagues, the army and the navy, out there as well.
I think that we'll become more involved in the north and I think we're getting better at it. The one thing that I would add, that has certainly extended our capability or will extend our capability up there, is the new Chinook helicopter with the fat tanks that it has. It will provide tremendous support to everything that's going on up there once we hit the final operation capability, which won't be for a little bit. But we certainly took it all the way to Alert and back this year.
