 They make the tube, and so at some point Boeing said, hey, you know what? It's not rocket science. Well, I guess it kind of is rocket science, but we can just spin this off, and we'll just buy our tubes from them. And oh, by the way, what that helps is then Spirit Aerosystems could also sell the tubes to Airbus or other manufacturers, Airbus being the biggest competitor to Boeing. And so that was kind of the thinking behind that.
