Every year, around May 10, people from all over the country come together to celebrate the anniversary of a famous UFO encounter. They gather around a monument erected by a group dedicated to all things paranormal and listen to a local tour guide recount the event and the circumstances surrounding it. While this sounds like one of many celebrations in spots throughout the United States, this particular event occurs in Poland, in the little eastern village of Emilcin. The report of a local farmer there, 42 years ago, captured the imaginations of generations of Poles and stirred up a fair amount of speculation and conspiracy theories.
