FBI's 1947 Portland UFO File: Police Spot Disks in the Sky

# FBI's 1947 Portland UFO File: Police Spot Disks in the Sky

By DeClassX

In the summer of 1947, the United States was gripped by a phenomenon it had no name for yet. On June 24 of that year, a private pilot named Kenneth Arnold reported seeing nine crescent-shaped objects flying near Mount Rainier in Washington State at speeds he estimated exceeded 1,200 miles per hour. The wire services ran the story, a reporter coined the term "flying saucer," and within days, the skies over America became the subject of the most concentrated wave of unidentified aerial sightings the country had ever seen. Now, a declassified FBI document — stamped Confidential and routed through the Bureau's San Francisco field office in August 1947 — captures a snapshot of that extraordinary moment, preserving a newspaper account from the Oregon Journal that describes what happened over Portland, Oregon on July 4, 1947.

The document is deceptively simple: a clipping from the Oregon Journal dated July 5, 1947, filed as an enclosure within an FBI report. But its contents are remarkable. Eight Portland-area law enforcement officers and deputy sheriffs, a harbor patrol captain, private citizens, the crew of a United Air Lines aircraft flying over Boise, Idaho, and a U.S. Coast Guardsman who reportedly photographed one of the objects near Seattle — all within a single news cycle — claimed to have witnessed disk-like craft in the sky. The FBI, clearly paying close attention, had this article collected, stamped confidential, and routed up the chain. The question of why the Bureau was tracking flying disk reports in the summer of 1947 is itself a thread worth pulling.

The Portland sightings began in earnest at 1:06 p.m. on Friday, July 4, when the East Side police station was flooded with calls from citizens reporting disks overhead. A general alert went out over the police radio. Within seconds — not minutes — two prowl cars radioed back that they had visual confirmation. The speed of that response is striking. These were not skittish civilians. They were trained law enforcement officers who had just been told their colleagues were also seeing something, and they reported in immediately.

Patrolmen Walter Lissy and Robert Ellis, both World War II veterans and, notably, licensed civilian pilots, pulled their car over near Oaks Park. What they described was unusual even by the standards of an unusual era. Within 30 seconds of stopping, they spotted three objects traveling at great height and speed. They heard no engine noise — a detail repeated throughout the article — but observed flashes. The objects moved erratically and changed direction mid-flight. As experienced aviators, both men were careful to hedge their estimates: without knowing the actual size of the objects, they acknowledged it was impossible to calculate speed or altitude. That kind of epistemic caution from credentialed witnesses makes their account harder to dismiss.

Patrolman Earl Patterson, in a separate car, had a different but equally puzzling encounter. He initially looked east, in the direction where the disks had been reported, and saw nothing. Then, seconds later, one appeared from the west, heading southwest. Patterson described it as aluminum or eggshell white — notably, it did not flash or reflect light, unlike what Lissy and Ellis reported, suggesting the witnesses may have been observing the objects from different angles. Patterson, himself a former Army Air Corps veteran, was categorical: the object was unlike any aircraft he had ever seen. His most striking observation was behavioral. The craft appeared capable of changing direction at a 90-degree angle without difficulty — a maneuver that, in 1947 aerospace terms, was simply not possible for any known human-made vehicle. Patterson speculated the object might be radio-controlled, which was his frame of reference for explaining something that seemed to move without inertia.

The harbor patrol team at the foot of Northwest Irving Street added further texture to the picture. Captain K. A. Prehn, Harbor Pilot A. T. Austed, and Patrolman K. C. Hoff all stepped outside when they heard the all-car alert and watched the objects move south over the Globe Mills at what they described as terrific speed. Prehn offered perhaps the most visually vivid description in the entire article. The objects oscillated as they moved, cycling through shapes — full disk, then half-moon, then nothing at all — before reappearing. He compared them to a shiny chromium hubcap off a car that wobbled, disappeared, and came back. That description — the oscillating, intermittently visible, metallic disk — would echo through UAP witness accounts for decades to come.

All of the witnesses were emphatic on one point: there was a conventional aircraft visible in the sky at the same time, and the disks were unambiguously not planes.

The FBI's interest in these reports is not incidental. In the weeks and months following the Kenneth Arnold sighting, J. Edgar Hoover's Bureau entered into a tense and sometimes contentious arrangement with the Army Air Forces to share information about flying disk reports. The Bureau ultimately withdrew from active investigation by the end of 1947, frustrated by what agents described as a lack of cooperation from military intelligence. But in those early weeks, the FBI was actively collecting, routing, and classifying newspaper accounts, witness statements, and field reports. The Confidential stamp on this document — a newspaper clipping — tells its own story about how seriously the government was treating these sightings behind closed doors, even as official public statements remained dismissive or noncommittal.

What makes this document worth examining today is not that it proves anything exotic. It doesn't. What it proves is that credible, trained, experienced observers reported something they could not identify, that the FBI found it significant enough to classify and preserve, and that the institutional response to the 1947 wave was far more engaged than the government's public posture suggested at the time.

The open question this document leaves on the table is the one the FBI itself never fully answered: what, exactly, were Patrolmen Lissy and Ellis, Earl Patterson, and Captain Prehn watching over Portland on the Fourth of July, 1947? Seventy-seven years later, the file is declassified. The objects remain unidentified.
