Project 10073 Record — Sheboygan, Wisconsin, 24 March 1966

On the night of March 24, 1966, two witnesses in Sheboygan, Wisconsin, observed an unidentified aerial phenomenon. The witnesses, who were traveling in a vehicle, first spotted two bright white lights centered over the road ahead of them at approximately 10:15 P.M. As they continued driving, they stopped directly beneath the object. The witnesses described the object as having two bright white lights with a span similar to that of a large airplane, accompanied by red and green lights. They noted that the object appeared to be at a low altitude, just clearing the treetops and houses. After initially disappearing, the object reappeared from the opposite direction and flew over them again. The witnesses reported no sound during the observation, which lasted approximately four minutes. They subsequently reported the sighting to the local police and the county sheriff's office. The U.S. Air Force, through Project Blue Book, investigated the report. Major Hector Quintanilla, Jr., Chief of Project Blue Book, corresponded with the witnesses, requesting further information via FTD Form 164. The official conclusion reached by the Air Force was that the object was an aircraft, noting that there was no data presented to indicate the object could not have been an aircraft.
