 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.
