Here is one last, quick comment. There was some discussion earlier about the cost of the plane—the cost of sustaining it over a 20-year period—but the understanding that I think we heard from the other witnesses is that the plane really is assumed to have a 35-year life.
Just to ensure that we compare apples with apples when we're talking about the cost of sustainment, the earlier gentleman talked about how in fact sustainment costs would be at least as much as the plane itself, if not more, over what he anticipated as the life of the plane, and I would gather all of us anticipate that the life of the plane is not 20 years but significantly more than that.
Mr. Wilfert, if there's time.
