More on Kennedy & Apollo
http://space.com/news/seamans_jfk_010827-1.html
This piece by Andrew Chaikin is worth reading to get a perspective on the Kennedy tapes. Chaikin, a writer for Sky & Telescope and a noted space historian, wrote one of the finest books worth reading on Apollo, "A Man On the Moon".
Buy it and read it; it's a classic, fun read written in the 90s.
