Is This a Beta? Or a Composite?

I'm guessing also composites and smaller electronics than ever before. My 757 is still pretty archaic inside, but it gets us there. I think we talked about two of the big pieces that have enabled this market to start to grow up. That's that electrical power systems, a lot of stuff that's come out of the electric car market. You've got increased automation or desire on some of these platforms that'll enable some things. And the third one is how do you manufacture these differently to get to a scale?
