Unidentified Flying Object (UFO) Sighting — Harrisville, Michigan, April 1966

This document is a Project 10073 record detailing a UFO sighting reported by a 19-year-old college student on April 4, 1966, near Harrisville, Michigan. The witness, while driving on U.S. Route 23, observed a large, glowing white ball with three protrusions illuminated by blinking red lights. The object reportedly hovered, moved backward and forward at approximately 10 miles per hour, and performed a rapid descent before stopping at tree-top level. The witness, who was alone, estimated the object's diameter at 12 feet and noted it was approximately 200 feet above the trees. The sighting lasted for 30 minutes. The witness attempted to call his father from a telephone in Harrisville, during which time the object followed his vehicle for one mile before disappearing, only to reappear later at the original location. The report includes a detailed weather analysis and notes that Wurtsmith Air Force Base was conducting flight operations in the area at the time. The investigating officer, Lt. Colonel R. S. Zuber, concluded that while the witness appeared sincere, the sighting was likely a combination of aurora borealis and swamp gas. Zuber further suggested that the witness's imagination may have been influenced by recent media reports and a separate, unrelated incident where a reflector was found tied to a tree in the same area. The document includes a hand-drawn sketch of the object by the witness.
