In April 1966, deputies from Portage County, Ohio, engaged in a high-speed pursuit of a bright, metallic disc-shaped object, leading them across state lines into Pennsylvania. The incident remains one of the most documented and debated UFO encounters in history.
On June 24, 1947, Fred Johnson, a prospector in the Cascade Mountains, witnessed a series of disc-shaped UFOs, experiencing physical effects on his compass, making it a significant yet lesser-known sighting on the same day as the famous Kenneth Arnold sighting.
