 Flying saucer crashing to Earth back in 1940s, hasty cover up of the facts, cover up which persists to this day. Roswell isn't just any mystery. It's potentially one of the greatest mysteries in human history. It's also one of the most covered up stories in history. In fact, many people, as I said, are unaware of the timeline. A lot of people don't think that there is a value in history with regard to ufology.
