Thank you.
If I could just speak specifically to the maintainers, what we're doing.... You talked earlier about the exponential rate of maintenance. It's not quite exponential that we're seeing. A lot of it's at the third line. A lot of this is how we're now using industry. Specific to this fleet and this aircraft, we've already taken a big step. We've generated almost 200 first-line maintainers by looking at how we do industry, how we use it at the second line, like we do in the navy, and to some extent in the army. We're looking at that in new fleets. We've looked at it across fleets: the C-17, how we maintain it, how we're doing the Cyclone, how we're bringing things in.
You're right. There are trends and there's a complexity around a military maintainer and everything they need to do. It's causing us to look through something we've called the sustainment initiative: how we're sustaining all the fleets, what really needs to be uniformed maintainers and what really could be a civilian experienced maintainer, who actually are more efficient as far as time on aircraft goes. That's what we see. That is really actually helping us on the maintainer side to change the trend, to actually be able to build the right first-level deployable maintainers, as you would be aware, while we have the rest of the enterprise at the appropriate place, be it industry or otherwise.
