The Michigan “swamp gas” UFO reports were two mass sightings of unidentified flying objects during the nights of March 20 and 21, 1966, in Michigan, United States. The first occurred around marshland near Dexter, while the second mass-sighting took place near the campus arboretum of Hillsdale College, about 50 miles away. The sightings took place amid a wave (or ‘flap’) of UFO reports throughout southern Michigan.

Neighborhoods in Michigan were terrorized over several days by strange craft that dove, hovered, climbed, and disappeared━only to reappear. One of these objects briefly landed in a nearby swamp. When a farmer and his son went to investigate, they observed a pyramidal object that was wingless, jetless, propeller-less. How could it fly? At the insistence of a leading Michigan congressman named Gerald Ford, Dr. Hynek’s Project Blue Book reviewed the matter thoroughly, and unfortunately announced that the witnesses had seen…swamp gas. A clear cover-up, it was an effort to tell the American people, “There’s nothing to see here, folks.”
