MINNEAPOLIS (FOX 9) – An archive of recently released UFO documents reveals a few unexplainable and unidentified sightings in Minnesota.
The National Archives and Records Administration (NARA) created the «Unidentified Anomalous Phenomena Records Collection» required under the 2024 National Defense Authorization Act.
The collection will feature government documents related to Unidentified Anomalous Phenomena (UAP), also known as UFOs. The agencies have until the end of the year to «review, identify, and organize each unidentified anomalous phenomena record in the custody or possession of the office for disclosure to the public.»
The collection currently includes thousands of documents pertaining to Project Blue Book. Of those, the NARA released files on dozens of Minnesota sightings investigated by the government program.
What is Project Blue Book?
The U.S. Air Force created Project Blue Book to investigate UFO sightings reported by civilians and military personnel. From 1947 to 1969, the program received 12,618 reported sightings, of which 701 remain «unidentified.»
According to Project Blue Book documents, the «unidentified» classification makes up the smallest number of reports. The most common evaluations are «identified» sightings, which are often categorized as satellites, aircraft, balloons, and astronomical events, including bright stars, planets, and meteors, that are mistakenly reported as UFOs.
While most sightings were identified as such, some reports left investigators puzzled about what witnesses saw in the sky. Here are some unusual sightings in Minnesota investigated by Project Blue Book.
‘Flying saucer’ in Hamel
A Project Blue Book investigation looked into a «flying saucer» seen by two boys, ages 8 and 10, in Hamel, Minnesota. On Aug. 11, 1948, the boys were outside playing in their backyard when they claimed an object landed a few feet away. The object spun once, then shot straight up in the air and eventually disappeared.
The children were «visibly frightened» and eventually told their parents about seeing a dull gray object that looked like two inverted plates approximately two feet wide, with no windows or wires, and made a whistling noise.
The sighting was reported to the Federal Bureau of Investigation (FBI), and an agent visited the house. At the scene, the agent noted a washtub covering the spot where the «flying saucer» landed.
The spot «appeared as though some heavy object had landed there or had been set down — as the ground was dented and protruding rocks had been leveled,» documents read.

A member of the military later went to the survey site, but the depression was partially filled with water. They took pictures of the indentation, collected dirt samples, and sent them to the FBI laboratory for evaluation.
Then FBI Director John Edgar Hoover acknowledged receiving the materials and said, «This material is being given appropriate attention and your office will be subsequently advised,» the letter reads. «I am assuring you of my desire to cooperate in these matters.»
While the FBI didn’t find any abnormalities in the samples, it was later sent to the Chemical Corps, a branch of the U.S. Army, but the findings were not disclosed in the 30-page report.
Project Blue Book records do not say whether the sighting was determined to be «unidentified,» but documents note «no astronomical explanation is possible for this incident.»

Two Air Force pilots and a civilian reported an unidentified object over Minneapolis on Nov. 30, 1953. The object appeared as a bright round light changing colors between white, red, blue, green and yellow.
According to records, the light stayed stationary at around 3,000 feet and appeared «to be about the size of a pea held out at arm’s length.» After about 30 minutes, the object disappeared.
The control tower at Minneapolis-St. Paul International Airport received reports of the object and scanned the sky, but nothing was detected on the radar. The Project Blue Book case file did not say whether this sighting was «unidentified» but noted there were no balloons or aircraft in the area at that time.

The engineers described the unidentified object as a gray mass with fuzzy edges but said it was hard to see clearly through the theodolite, an instrument used for measuring angles.
They believed the flying object was a jet aircraft, but the case files state there were several unusual factors, such as the speed, lack of sound, and that the vertical dive was a «highly dangerous if not suicidal maneuver.»
It was later determined the balloon was the only known air traffic at that time, and the sighting was determined to be «unidentified.»
