I went to the Smithsonian Channel site and signed in. Under the blurb for this show was a tag, I think it was 'how to watch'. It said sign in through your cable provider if they carry the Smithsonian Channel and had a bunch of cable company tabs - 'Charter Spectrum' was one of the choices and does carry Smithsonian so I clicked it and signed in under Spectrum and up pops a link where I can watch the full 1 hr 32 min of the show.
Addition, from there I was able to access the whole library of Smithsonian Channel shows.
