I know you read in the press a lot about people who don't typically understand that fatigue on an airplane actually matters. It's probably one of the biggest driving points for how long this airplane is going to be able to fly.
Could you comment on how Canada and Australia have been sharing data on these airframes? Could you comment on how we put so much time, money and effort into making sure we understand where these airplanes are with regard to fatigue, and why that's important? Obviously, the laymen will say that this is going to be the leaky-sub syndrome all over again, which I don't think is a great comparison. I'd like to hear your comments on that.
