Annie Jacobsen, an editor at the Los Angeles Times Magazine, has written a book purporting to tell the real history of Area 51 and the Roswell Incident. Her book, which is based largely on interviews with people who lived and worked at Area 51, manages to simultaneously explain why the site would be so highly classified, while also trading in kind of mundane Cold War shenanigans—in other words, it's fairly believable. That is, except for the explanation one source gave her for Roswell, which is possibly the most insane story I have ever heard about that supposed alien crash landing. (And I watched the WB teen drama.) Scroll down to the section on "Interview Highlights" to read it.
