Well, the aircraft has hovered around seven or eight critical deficiencies, but they're always changing. They correct some and new ones get added. Of course, they don't want to reveal what those are, because it's related to the combat effectiveness of the aircraft.
The problem with the F-35 is that it's still in low-rate initial production, and they've built several hundred aircraft. The U.S. has acquired almost 25% of its target fleet, and the plane is still not completely finished yet. I think the consequence is that once you are in this world, you bring money, because this is the nature of the beast. It's never really going to be fixed, but you can't afford not to go there. You can't afford to go back to fourth-generation aircraft that are more predictable, because they aren't survivable anymore. It's a dilemma, but you just bring money.
