Boeing's First 787-10 Enters into Final Assembly

I am well-aware (well..from what I read and from what I saw thru photographs) that the Boeing Aircraft Company USED to actually manufacture airplanes and many of their components right at their facility in Washington.

From the little I was able to learn from current news articles and photographs, Boeing no longer makes airplanes - it simply ASSEMBLES them at its Wash. facility with mostly foreign-made assemblies. Did I understand correctly - anyone know what per-cent of those airframes ( obviously, Boeing does not make electrical, hydraulic, comm and nav, and power-plants themselves ) are actually made by Boeing ?
