UFO Report — Donnybrook, North Dakota, 19 August 1966

This document is a formal UFO sighting report filed by the 862nd Combat Support Group at Minot Air Force Base, concerning an incident on 19 August 1966 near Donnybrook, North Dakota. The witness, an employee of the U.S. Border Patrol, reported observing a white, silvery, aluminum-colored round disc with a dome top. The object was estimated to be 30 feet in diameter and 15 feet high. According to the report, the object was first seen floating down the side of a hill, wobbling from side to side about 10 feet from the ground. Upon reaching the valley floor, it climbed to approximately 100 feet, moved across the valley to a reservoir, and hovered over the water for about one minute. The object then moved to a small field where it appeared to land, hovering about 10 feet above the ground. The witness noted that the object was tilted on its side and featured a large dark spot in the center with three smaller spots forming a triangle. When the object departed, it produced a rushing air sound and disappeared rapidly into the clouds. The witness also reported that static blocked out his radio contact when the object came close to his position. Major Chester A. Shaw, Jr., who interviewed the witness, described him as a practical individual not inclined to relate wild stories. Despite the witness's credibility, the investigation found no radar returns for the object. An inspection of the site revealed two sets of triangular depressions and displaced rocks. Major Shaw concluded that while the witness's observations could not be discounted, the physical evidence was likely the result of local wildlife, such as grouse, coyotes, or badgers. The report includes several attachments, including photographs of the site and weather data.
