[...] it is a non-starter in the case of the C-141.

I assume that, like Chris, you have no better theory to propose? You
prefer
to just pooh pooh suggestions put forth by others?

It some cases the "theory" is so far from reasonable as to require it.

If you must have a "better" guess try go with this one: the planes no
longer belong to the Air Force but to a scrapper and the markings
that proclaimed them as such had to be defaced and some bubba
determined the quickest & easiest way to do so was by stabbing
some bit of a big machine through the markings.
