I don't know how to measure that. I don't know what dates they're referring to.
Have we had some delays in the program? Yes, we have. They've been well publicized. We went through a year-and-a-half engineering review to reduce the weight on the STOVL airplane. That added time to the original schedule.
I don't recognize the number of four years. I've seen it in their writing, but I don't know what they're referring to.
But there is no delay on the Canadian airplanes, I can tell you that for sure.
