That's true for Boeing aircraft as well. They are just assembled in Everett. They are built all around the world. 500+ subcontractors in Europe alone.
But the engineering work was done here for the most part. Some engineering was outsourced but only to a small handful of established and respected companies. And that's the point Hillary seems to be trying to make, that the critical aerospace industry infrastructure is not being used in the US so it'll disappear. She is failing to make the point because she either doesn't know what she's talking about, or she doesn't think the country is smart enough to understand that cheap doesn't equal good when it means nobody here can design stuff anymore. But she seems to think we're all idiots and can't grasp the concept of an industrial base or the fact that just because 90% of the country earn less money than the average aerospace engineer, it doesn't mean that the average American thinks we simply shouldn't have any engineers at all.
But she's a democrat and they get votes by pandering to the lowest and highest levels of American society, the ones who either have their hands out yelling "gimme!" or those who have money they didn't earn and who feel so guilty about having money that they feel they must force everyone else to fork over money to those shouting that they want more free stuff. Both groups are ignorant and gullible, and her speeches are tailored to their attitudes so she won't talk about eroding an industrial base, she'll talk in generalities, spouting nonsense about the evils of corporate greed and offshoring causing a loss of jobs. It's more complicated than that, but she won't ever admit it in public.
