So The Right Stuff is TOTALLY not a documentary. Tom Wolfe's book was fast'n'loose with the truth, and the movie is fast'n'loose with the book. Watch "Astrospies" as linked above. It'll take you an hour. You have to keep in mind that the whole thing is a sleight of hand - civilian space programs are all about military space programs and always have been. William E Burroughs wrote a great book on the NRO and its impact on foreign policy years before the NRO's very existence was declassified - when he was interviewing Hans Mark about a hypothetical NRO, he was interviewing the guy in charge. It's fun to read these days because everything discussed in it now has a wikipedia page... but the perspective is still a virtually unknown one. I was not only alive during the Cold War, I was living in Los Alamos, NM. I'm well aware that my opinion (and perspective) is definitely in the minority. You're new here.
