From a safety standpoint, in our view one of the things that we do in the basic design is the pilot always has the ultimate authority of control. There's no computer on the airplane that he cannot override or turn off if the ultimate comes. In terms of any of our features, we don't inhibit that totally. We make it difficult, but if something in the box should behave inappropriately, the pilot can say 'This is wrong' and he can override it. That's a fundamental difference in philosophy that we have versus some of the competition.
