I love the words ‘secret’ and ‘facility’ when in the same sentence. It makes me think of The Spy Who Loved Me , the classic Bond movie starring Sir Roger Moore. Part of the movie is shot at a secret, supertanker that forms part of evil villain Karl Stromberg’s plan to start a nuclear war. Another part is shot at a hidden underwater lair, Atlantis, which Stromberg plans to survive the nuclear war in. Anyway watch the movie if you haven’t seen it. It’s one of the classic Bond movies.
