Many full scale projects are done with external layups at the leading edge and the seams of the fuselage. I don't know if Raptor was done this way, but that's one possible reason.I have a question. With the CNC plugs, I thought there would be min body work being all machined / digital / autocad, etc.... This is going back years ago when they were doing the body work, been meaning to ask this. How come so much body work afterwards?
