I want to come back to Mr. Kuruc's last question in terms of the challenges that would be posed.... The more jets.... We go from the Hornets to the F-35s, and we may have sixth-generation jets coming up. Pilots are not automatically qualified to fly one aircraft when they're qualified to fly another aircraft, are they? Maintenance crews would have to learn various different aircraft, so it does pose a challenge. I understand it's not an insurmountable challenge, but certainly having multiple different jets introduced at the same time.... If we were to take 16 F-35s plus go to another supplier for the others, it would pose a number of challenges, which I assume would increase costs, would it not?
