Just about everyone has heard of Area 51, the famous “secret base” that might or might not be holding aliens – and that may be alive or not. There is, however, something strange about Area 51 – and at other top secret facilities, too. As you’ll see now. From 2003 to 2009 I lectured at Ryan Wood’s annual UFO Crash-Retrieval Conference, which was held in Las Vegas, Nevada. As is so often the case at such conferences, an attendee came up to me at the 2008 event with a very strange story to tell. Aged around thirty he said that his now-retired father had worked out at Area 51 in the early 1980s, specifically in the development of Stealth technology for military aircraft. The guy said that on several occasions, in the 1990s, he had asked his father about the rumors of crashed UFOs and dead aliens held at the secret base. His father said that the only thing he knew about aliens at Area 51 came from watching TV shows. Indeed, he told his son that he had never seen any evidence at all of alien-related activity at Area 51. But, there was one strange event that the man was willing to share with his son – and which was then shared with me. The story told to me was that on one occasion in January 1981, a pedal bike was found deep in a remote part of the vast amount of land that is collectively known as Area 51. Yes, a bicycle. The highly-sophisticated sensors that are carefully placed all around the facility had picked up the sudden presence of something not far from one such sensor. So, a security team was quickly sent out to investigate. It was that team, I was told, which found the bike. But, there was something very strange about the bicycle: it was extensively damaged – as if it had plummeted to the ground from a great height.
