Waubun, MinnesotaOctober 1953

On October 11, 1953, a farmer near Waubun, Minnesota reported seeing two unusual objects in the sky. The first object, which appeared around 11:30 a.m., was described as a large flat disk with a buzzing sound. According to the report, the disk had several long, slender feelers or antennae attached to its bottom, and what looked like a goose neck protruding from the front. The object moved slowly over the observer's farm yard toward the west and was visible for approximately five minutes.

Just minutes later, a second object flashed across the same area. This one was triangular and traveled very rapidly in a southerly direction, disappearing from view in just a few seconds. The observer was a young farmer who lived about three miles west and three miles north of Waubun. According to the Ground Observer Corps (a network of civilian volunteers who watched the skies during the Cold War), the man was well known and reliable in the community, and the corps personnel stated they did not believe his imagination was supplying the details of his account.

The U.S. Air Force's Air Technical Intelligence Center requested that the source be thoroughly questioned about possible exaggeration. The report was referred to the 4632nd Air Intelligence Service Squadron at Fort Snelling, Minnesota, which conducted a formal interview using the standard technical intelligence form. After analyzing the case, Air Intelligence officials concluded that further investigation was not necessary. The OCR text of the case file is difficult to read in places, but the file indicates the Air Force evaluated the sighting as "C-4," which the form suggests means "Unknown." The complete case file, as held by the National Archives, is reproduced below in 8 pages.
