Budd Hopkins was visiting Cape Cod when he saw a UFO.
Like other UFO sightings, Hopkin's experience only lasted about three minutes.
Hopkins described the floating object in the sky to be similar to a flat balloon, but it obviously wasn’t.
After his first sighting, Hopkins started to listen to stories of people who said not only have they seen UFOs, but that they were abducted by aliens.
From listening to all of the stories, Hopkins found aliens were short, had large black eyes, thin lips, and gray skin.
Aliens were out to harvest sperm or eggs.
