3. Men In Black

In 1947, a seaman claimed to have seen six doughnut shaped UFOs flying in the air above Maury Island off the Puget Sound in Washington. One of the objects dropped debris on the deck, injuring his son and killing his dog. The next morning, the seaman claimed a man dressed in black and driving a black Buick showed up at his doorstep and made vague threats that his family would be in danger if he ever spoke to anyone about the incident.
