After half a century of investigation, Stanton Friedman, a former nuclear physicist who worked on fission and fusion rockets for companies like Westinghouse and Aerojet General Nucleonics, is convinced that not only are UFOs real, the government has known about them since 1947 or prior. Mr. Friedman states “there is overwhelming evidence that planet Earth is being visited by intelligently controlled extraterrestrial spacecraft and that some UFOs are ET spacecraft, though most are not - a few people in the U.S. and other governments have known the above since at least 1947 and employ a “need-to-know” policy regarding this knowledge; that is, the knowledge is highly classified largely as sensitive military information.” Mr. Friedman exposes the many layers to the conspiracy regarding the UFO presence on earth garnered from decades of research.
