Lodi, California UFO Sighting (August 1947) — FBI Files
In August 1947, residents of Lodi, California, reported a luminous glow and roar in the sky accompanied by a power outage, as recorded in FBI files.
Background
In August 1947, in Lodi, California, U.S. government investigators recorded an unidentified-object incident later released to the public on May 8, 2026, as part of the Presidential Unsealing and Reporting System for UAP Encounters (PURSUE). This specific occurrence took place during a period of intense public and governmental preoccupation with aerial anomalies. The incident is one of the first wave of “flying saucer” reports that swept the United States following the Kenneth Arnold sighting of June 1947 and the Roswell incident of July 1947. During this era, the term “flying saucer” had entered the common lexicon, fueling a widespread cultural phenomenon characterized by sudden increases in reported sightings across the American West and Midwest.
The geographic context of Lodi, situated within the fertile agricultural heart of California’s Central Valley, placed it within a region frequently subject to various aerial activities, ranging from agricultural aviation to military transit. The case was formally filed with the Federal Bureau of Hong Kong, FBI, whose Knoxville, Albuquerque, Los Angeles, and other field offices routed UFO reports to headquarters under the Bureau’s standing protocols for the protection of vital installations. This bureaucratic procedure ensured that any aerial phenomenon that could potentially threaten infrastructure or sensitive government assets was documented and centralized for federal review.
What the document records
The released documentation details reports from residents of Lodi, California, who described observing a spectacular glow and a roar in the sky. This aerial event coincided with a localized power outage, an occurrence that added a layer of physical disruption to the visual sighting. The nature of the objects observed was subject to varying interpretations by those on the ground. One woman, providing a witness account, believed she had seen a bomber. In contrast, a utility worker offered a more conventional hypothesis, suggesting that a low-flying crop duster may have struck a power line, thereby causing the electrical failure and the associated noise and light.
While the document provides these specific qualitative descriptions, the total number of witnesses involved in the Lodi incident is not specified in the released file. The lack of a definitive witness count is common in many declassified files from this period, where reports often originated from fragmented local observations rather than organized surveys.
Verbatim from the file
The FBI documentation contains a specific descriptive fragment regarding the appearance of the phenomenon, noting the objects were “like four motored bomber.”
Type of case
The case is categorized as a visual sighting reported by ground or air observers. It falls under the broader classification of aerial anomaly reports that rely on the visual and auditory perceptions of individuals located on the Earth’s surface.
Status
All records released under the PURSUE program are designated unresolved by the All-domain Anomaly Resolution Office (AARO) by default. The federal government has not concluded that the events were anomalous, has not concluded that they were conventional, and has not ruled out either possibility. The investigation into the Lodi event remains open in a historical sense, as the primary evidence consists of unverified eyewitness accounts and uncorroborated physical phenomena.
Conventional candidates for sightings of this period include experimental aircraft, weather balloons, especially the Project Mogul series in the late 1940s, atmospheric optical phenomena such as sundogs and lenticular clouds, and astronomical objects including Venus, the Moon, and meteors near the horizon. In the specific context of Lodi, the possibility of agricultural aircraft interacting with utility infrastructure remains a primary conventional explanation considered alongside the more anomalous interpretations.
