In 1965 hundreds of witnesses saw an object descend from the sky and crash into the woods outside the small Pennsylvania town of Kecksburg. The official government report describes it as a meteor, but eyewitnesses claim to have seen the object up close. They describe it as copper-colored, acorn-shaped, and covered with strange writing. Was it a UFO? And if not, why did the military quickly blanket the area and remove it to a secured Air Force base?
