Lake Leelanau, Mich, March 1956March 1956

In late March 1956, residents in and around Lake Leelanau, Michigan reported seeing a bright object in the night sky. The sightings occurred on March 26 and 27, with at least fifteen people in separate locations observing the phenomenon. A young metal worker who first spotted the object at around 10:45 p.m. on March 26 described it as crescent-shaped with a reddish-orange stem, about the size of a dime at arm's length. He and three companions watched it through binoculars as it seemed to move erratically and fade intermittently before disappearing.

Over the following nights, other groups of witnesses reported similar sightings from different parts of the area. Some saw a round, bright light that changed colors from red to white to green. Others described it as moving slowly westward or dropping toward the horizon. A woman in Cedar reported seeing a large reddish-orange object that terrified her and caused her three dogs to howl and cower in fear. A Philco technical representative who saw the object on several occasions stated he thought it was almost certainly a bright star, though at times it seemed to fade and reappear.

The investigation was led by Sergeant Philip W. Beilfuss of the U.S. Air Force's 4602d Air Intelligence Service Squadron, based at nearby Empire Air Force Station. Beilfuss and Lieutenant Eldon Balko traveled to Lake Leelanau to interview the witnesses. They discovered that there were no radar contacts with the object and that the sheriff of Leelanau County had concluded it was likely just the planet Venus. When Beilfuss and Balko themselves observed the object, they thought it appeared to be a bright star that disappeared behind clouds.

After interviewing Professor Everett M. Phelps from Wayne University's astronomy department, investigators learned that Venus was unusually bright in the night sky at that time of year. Phelps noted that Venus viewed through binoculars can appear crescent-shaped and explained the color changes as effects of binocular optics and atmospheric refraction near the horizon. The investigator concluded that all sightings were probably the planet Venus, and the Air Force concurred with this assessment, marking the case as "Probable Astronomical" in its evaluation. The case file, including the statements of at least ten named witnesses and supporting investigative materials, is reproduced below as held by the National Archives in 21 pages.
