Frank Mannor

Frank Mannor was a Michigan farmer who, on March 20, 1966, observed a glowing object near his property in Dexter, Michigan, where it hovered over a swampy area. This sighting was one of several reported in the area that week, prompting a major media frenzy and significant media attention. J. Allen Hynek, Air Force consultant on Project Blue Book, controversially attributed the phenomenon to swamp gas, an explanation that was widely criticized and which Hynek later deeply regretted. The Michigan swamp gas incident became a turning point in public attitude toward official UFO explanations and contributed to the call for the Condon Committee investigation.
