I would just say, too, that the commander of the air force has to look at the capability of the helicopters we have currently on the ground, and where they are in terms of their life, because we didn't purchase those aircraft new. They had been used by the U.S. army, and therefore they had a lot of hours on the aircraft. So at what point will they be in another 18 months? And I'll just say to you that the very fact that we can do rotations—and on this last rotation I do not think we took a single casualty—again goes to the importance of the helicopters in enabling a safe rotation of our troops.
But they're being used hard. They are carrying literally tens of thousands of soldiers, sailors, airmen, and civilians around the battlefield safely. So where they will be terms of their full life in 2011, I don't know, but that will have to be another assessment not only involving General McQuillan's organization but also the chief of the air staff in terms of what it will take to get those aircraft back up and reset them and where they will be in their lives when they're reset vis-à-vis the new Chinook Foxtrot helicopters, for which the government has signed a contract, and I believe we'll be receiving them in the 2013 or 2014 timeframe. So all of that will have to be weighed.
At this point in time, I don't have another answer for you.
