 We're actually out here performing flight tests for the F-35C to open up the flight envelope and see what we can learn to get the F-35 ready for carrier evolution launch and recovery. The difficulties of maintaining this aircraft on Nimitz is that, one, it's the first time we've ever brought this type of aircraft aboard with the training that we go through. We have to go very slow to ensure that every step is done safely. First on the Nimitz we're prepared that we had a small contingent come out to us in Pax River, Maryland and we provided a small cadre course for the individuals to learn about the F-35, a taxi and towing, learning all the intricacies of the F-35 that no others would see unless they were inside the program. Every moment being on the deck, working on the aircraft, being around, working with the crew, bringing the aircraft up and down on the elevators. I think every day is a new challenge, new excitement and we learn something new every single day, every time we move the aircraft. Every moment we're learning something new about the aircraft and how it interacts with the flight deck crew and the aircraft carrier itself, so it's pretty tough to learn on the fly, but that's what we're doing out there. That's what we've trained for on Pax River for the past five years from the aircraft. I know everybody had the same feeling with the aircraft when it came in, it touched, it trapped. And then the next day when it launched off, it was still wonderful, not every day you get to make history and we made history with the F-35C for the Navy as a whole.
