A 52-page collection of FBI records documenting UFO reports from June 1947 to July 1968 has been made public. Released on May 8, 2026, through the Trump administration’s PURSUE archive, the material was distributed by the U.S. Department of War rather than the FBI. This specific chain of custody aligns with the archive’s mandate to declassify historical records.
The documents, identified as Volume 1, Serial Number 1 of case file 62-HQ-83894 from the FBI’s Central Records Center, provide a more complete picture than previous versions. While some of this material had been posted on the FBI Vault website, the PURSUE archive version contains fewer redactions and includes pages that were previously missing. One notable detail in the excerpt is a date stamp reading 8/11/1274199; however, the provided materials do not explain the meaning of this sequence, leaving it unclear if it is a reference number or a filing code.
Scope of the Investigation
The file’s 21-year timeframe begins in June 1947, the same month Kenneth Arnold reported seeing nine crescent-shaped objects near Mount Rainier—an event that introduced the term “flying saucer” and launched the modern UFO era. The collection concludes in July 1968, two years before the termination of the Air Force’s Project Blue Book.
Described by the bureau as “investigative,” the file consists of a variety of records, including:
- Eyewitness testimonies and researcher accounts
- Technical proposals concerning potential propulsion systems
- Public reports and extensive media coverage
- Convention programs and accounts of high-profile incidents
- Photographic evidence from Oak Ridge, Tennessee
The inclusion of photographs from Oak Ridge is particularly significant given the city’s Cold War status as a classified site that produced enriched uranium for the Manhattan Project. The documentation suggests the FBI viewed these sightings as matters of record requiring classified documentation rather than mere rumor.
Context and Accessibility
This release is part of a broader trend of government transparency regarding UFO investigations. While the Navy emphasized pilot safety and the Air Force focused on national security threats, the FBI’s records highlight its focus on public reporting and criminal investigations. The “investigative” nature of the file confirms that agents actively interviewed witnesses and collected evidence over two decades.
Accessing the material requires a specific step for the reader. The 29.0 MB PDF is not viewable directly in a browser and must be downloaded to be read. While this creates a practical barrier for casual viewers, it remains a vital resource for researchers attempting to determine exactly what the bureau knew and when they knew it.
For those new to the subject, the file serves as an introductory point, while for long-term researchers, it provides another piece of a larger historical puzzle. The release confirms that the FBI treated the phenomenon with a level of formality, documenting the labor of its agents through official reports and evidence collection during a pivotal era of American history.
