Project 10073 Record Card — Roseville, Michigan, 27 April 1952

On April 27, 1952, at approximately 1615 hours, four individuals in Roseville, Michigan, observed four unconventional aircraft in the sky. The witnesses, who possessed prior military experience, were in a backyard pitching horseshoes when they first spotted a silver, round object that appeared motionless. Using high-power binoculars, they observed the object turn and change shape into an oval or egg-like form. It featured a dark underside, though it was unclear if this was a door or a painted side. The object subsequently dropped straight down and stopped. Two additional silver, cigar-shaped objects, larger than the first, appeared in the same area. The witnesses reported that these objects appeared to originate from the initial ball-shaped object or simply materialized in the same vicinity. The objects remained visible until approximately 1700 hours, at which point the ball-shaped object ascended rapidly and disappeared, while the cigar-shaped objects departed in easterly and westerly directions. During this same period, a fourth object—a silver, cigar-shaped craft—was observed traveling at a tremendous speed from the northeast to the northwest at a great altitude. The observers tracked this object with binoculars, noting that it traveled horizontally without making any sound or leaving an exhaust trail. The sky was clear and cloudless throughout the 45-minute observation. The witnesses asserted that the objects were not weather balloons or conventional aircraft, citing their movement and altitude. Captain Anthony W. Rosinia of the 4708th Defense Wing documented the report, noting that he could not verify the reliability of the source or the credibility of the information provided. The incident was subsequently recorded on a Project 10073 record card, which categorized the conclusion as unknown, noting that the objects were too fast for balloons and that no aircraft were in the area.
