1947 Air Force Memo Forwarded Flying Disc Report to FBI

# 1947 Air Force Memo Forwarded Flying Disc Report to FBI By DeClassX

In the summer of 1947, the United States was gripped by a sensation unlike anything it had experienced before. On June 24 of that year, private pilot Kenneth Arnold reported seeing nine crescent-shaped objects streaking past Mount Rainier at speeds he estimated exceeded 1,200 miles per hour. The press coined a phrase to describe what he'd seen: flying saucers. Within days, reports were flooding in from across the country. Within weeks, the U.S. military and its intelligence apparatus were quietly mobilizing to make sense of it all.

This declassified memo — brief, bureaucratic, and easy to overlook — is a small but telling artifact of that mobilization. Dated August 4, 1947, it originates from the Office of the Assistant Chief of Staff, A-2 Intelligence, Headquarters Fourth Air Force, stationed at Hamilton Field in northern California. Its recipient is the Special Agent in Charge of the FBI's San Francisco field office, located at 111 Sutter Street. The subject line reads simply: Investigation of "Flying Discs."

The memo's author, Major William R. Graham, Deputy Assistant Chief of Staff for Intelligence, is forwarding two enclosures: a witness statement from someone identified as Rankin, dated July 30, 1947, and a newspaper clipping dated July 3, 1947. Neither the statement nor the clipping is reproduced in this page of the document, but their existence — and the fact that a senior Air Force intelligence officer saw fit to route them directly to the FBI — speaks volumes about how seriously the government was treating the flying disc phenomenon in those early weeks.

The stamp at the bottom of the page confirms receipt: the FBI's San Francisco office logged the memo on August 7, 1947, just three days after it was sent. A routing notation, partially redacted, suggests the document was passed along internally within the Bureau. Someone, somewhere in J. Edgar Hoover's organization, was reading about flying discs.

To understand why this document matters, it helps to appreciate just how compressed and chaotic the summer of 1947 truly was. Arnold's sighting on June 24 set off a chain reaction. By early July, the Army Air Forces were publicly dismissing most reports while privately scrambling to investigate. The Roswell incident — in which the Army Air Field at Roswell, New Mexico, initially announced the recovery of a "flying disc" before quickly retracting the statement in favor of a weather balloon explanation — had already occurred by the time this memo was written, playing out dramatically between July 8 and July 9. The Rankin statement referenced here was gathered on July 30, just three weeks after Roswell, in a national climate where flying discs were front-page news and genuine public anxiety was running high.

The involvement of the FBI is particularly significant. The Bureau's role in early UFO investigations is a chapter of intelligence history that often gets overshadowed by the Air Force's more prominent programs — Project Sign, Project Grudge, and eventually Project Blue Book — but the FBI was very much in the picture during this formative period. Director Hoover himself expressed interest in the flying disc reports, though he grew increasingly frustrated with what he perceived as the military withholding information from his agents. A well-known letter from Hoover, written in July 1947, complained bitterly that the Army was allowing the FBI to investigate "saucers" only after the Army had already examined them, leaving Bureau agents with little of investigative value. The memo before us, in which the Air Force is proactively forwarding materials to the FBI rather than holding them back, may represent exactly the kind of inter-agency cooperation Hoover was pushing for — or it may be a carefully controlled drip of information, sharing a witness account and a newspaper clipping while keeping more sensitive materials close.

The geographic context adds another layer of interest. Hamilton Field, where the Fourth Air Force was headquartered, sat at the center of a region that had seen a notable concentration of flying disc reports in the summer of 1947. California and the Pacific Northwest were, in many ways, ground zero for the early UFO wave. Arnold had made his sighting over Washington State. Numerous other reports came in from the West Coast in the weeks that followed. Having the Fourth Air Force's intelligence office routing materials to a San Francisco FBI field office places this memo squarely within that regional epicenter.

The document's classification level — Confidential — is also worth noting. This was not a routine administrative communication. Whatever Rankin had to say in that July 30 statement was considered sensitive enough to require controlled handling and a formal forwarding memo from a major in Air Corps intelligence. We don't know who Rankin was — a civilian witness, a military observer, a pilot? — but the machinery being deployed to manage that single account is a reminder that behind the public dismissals and official nonchalance, the government's internal response to the flying disc reports was anything but casual.

Decades later, documents like this one began to surface through Freedom of Information Act requests, gradually assembling a picture of an intelligence community that was simultaneously downplaying the phenomenon to the public and diligently collecting, routing, and filing every scrap of information it could gather. This memo is one small tile in that larger mosaic.

What remains unknown, and what invites further research, is the content of the Rankin statement itself. What did Rankin see? Where? Under what circumstances? And what did the July 3 newspaper clipping describe — a local sighting, a national story, something specific enough to catch an Air Force intelligence officer's eye? If those enclosures survive in the archive, they would transform this brief forwarding memo from a bureaucratic footnote into a primary witness account from the very first summer of the modern UFO era. The search for those documents is very much worth continuing.
