I'm sure the designers of the DC-10 and 747 would be extremely surprised
to hear that.

I doubt that they would. I can't speak directly to the DC-10, but my
history book on Boeing tracks the lineage of all of the Boeing aircraft, and
at each step along the way, each new aircraft borrows heavily from the
previously built aircraft. In many cases, the passenger aircraft projects
started as military contracts.
