Something odd happened in the summer of 1947. The FBI was already investigating flying discs before it officially had permission to do so. That detail, buried in the newly released PURSUE archive document 65_HS1-834228961_62-HQ-83894_Section_2, shifts the timeline of federal involvement in the UFO question.
The document, a 31.9 MB collection of records spanning June 1947 to July 1968, includes an Office Memorandum dated August 8, 1947. It came from the SAC in San Francisco. Sent to the Director, FBI. It mentions photostatic copies of three letters dated August 4, 1947. These were furnished by Major William R. Graham, Deputy AC of S, A-2, Air Forces, at Hamilton Field, California.
Read that again. The Air Force was handing over documents to the FBI. The Fourth Air Force, based at Hamilton Field, was already running the investigation. The Bureau was receiving their results. And all of this happened before FBI headquarters issued instructions that the Bureau would conduct its own inquiries into flying disc sightings.
That means local FBI field offices were already moving. The San Francisco office was in communication with military intelligence. They were coordinating. Collecting letters. Building a case file. The central directive came after the fact, a formal stamp on work already underway.
Why does that matter? It suggests the flying disc phenomenon was taken seriously at the operational level from the start. The official narrative has always been one of confusion and reluctant study. But these records show a different story. Field agents and Air Force intelligence officers were sharing information within weeks of the Kenneth Arnold sighting in June 1947.
The document also contains an Office Memorandum dated August 13, 1947, from the SAC in Newark. It concerns a flying disc reported at Hackensack, New Jersey, on August 1, 1947. Two witnesses: Charles Caselia, Jr., and William Truex, a soldier stationed at Fort Dix. A soldier saw something. He reported it. The Newark FBI office opened a file. The machinery of investigation was already turning.
Look at the scope. The archive includes high-profile incident accounts. Photographic evidence from sites like Oak Ridge, Tennessee. That is significant. Oak Ridge was a nuclear facility, part of the Manhattan Project. If something was photographed there, the security implications were immediate. The document also contains technical proposals regarding potential propulsion systems. Engineers and scientists were already trying to figure out how these things might work.
This is not a story of a few scattered letters. It is a record of institutional response. The FBI, the Air Force, and the War Department were building a coordinated investigative framework. The PURSUE archive, released by the U.S. Department of War on May 8, 2026, makes that framework visible for the first time.
Where does this lead? It forces a re-evaluation of everything that came after. The Robertson Panel in 1953. The Condon Report in 1968. Project Blue Book. If the government was running a coordinated investigation in 1947, before any official policy existed, then the later public posture of skepticism looks less like genuine uncertainty and more like a managed position.
The records stop in July 1968. That is not an accident. That is the year the Condon Report concluded there was nothing to see. The PURSUE archive suggests the conclusion was reached long before, and the public report was a closing statement on a two-decade investigation that began with field agents and Air Force majors sharing photostats of letters in August 1947.
