I dunno, David, when I used to visit Al at Princeton, he seemed to be
saying that  he just assumed that c didn't change -- no substantial reason
-- that it didn't matter anyway -- and that he just assumed that nothing
could go faster than something -- he took that to be light.  But he never
did come to any conclusion re just what "light" is -- He always thought
that it was a joke that he got the Prize for the idea of a "photon."

Or something like that.
