Jeffersonville UFO Sighting (1946/1947) — FBI Files
FBI records detail a 1946/1947 unidentified object sighting in Jeffersonville, New York, reported by a member of the U.S. Armed Forces.
Background
In the period spanning 1946 and 1947, the landscape of American aviation and national security was undergoing a profound transition. As the Second World War concluded, the rapid advancement of aeronautical technology left both the public and military intelligence agencies grappling with new, unexplained aerial phenomena. During the preceding years of the war, Allied aircrews had frequently documented the presence of luminous, unidentifiable objects that appeared to shadow or pace their bombers during combat sorties. These encounters, often categorized as foo-fighters, established a precedent for the high-altitude anomalies that would dominate much of the post-war era.
The Jeffersonville UFO sighting occurred in Delaware Township, within Sullivan County, New York. This region of the Catskill Mountains, characterized by its dense forests and undulating terrain, provided a quiet backdrop for an incident that would eventually be documented by federal authorities. The records pertaining to this event were part of a larger collection of intelligence that remained classified for decades, only becoming accessible to the public on May 8, 2026, through the Presidential Unsealing and Reporting System for UAP Encounters (PURSUE).
During this era, the Federal Bureau of Investigation maintained a structured protocol for handling reports of unidentified aerial phenomena. Because such sightings were perceived as potential threats to the security of vital installations and national airspace, field offices in cities such as Knoxville, Albuquerque, and Los Angeles were tasked with collecting and routing these reports to FBI headquarters. This centralized system ensured that any object capable of interfering with military or civil infrastructure was tracked by the central government.
The Jeffersonville Report
The specific details of the Jefferson andville incident are derived from a localized news report rather than a formal military debriefing. Sometime in late 1946 or early 1947, a small, local newspaper serving the Jeffersonville area published an article discussing the phenomenon of flying saucers. The author of this piece was a member of the U.S. Armed Forces, lending a degree of professional credibility to the report, though the newspaper did not provide follow-up coverage in subsequent issues.
The primary source for the information contained within the FBI files was an individual identified as Major Walkers. The documentation indicates that Major Walkers provided the details to the Bureau, reporting the occurrence for what it might be worth. While the report contributed to the official record of anomalous activity in Sullivan County, the released documents do not specify the exact number of witnesses who observed the object. The lack of granular detail regarding the observers suggests that the report may have relied on the singular account or the observations of the author themselves.
Classification and Analysis
The Jeffersonville case is classified as a visual sighting, a type of encounter reported by observers on the ground or in the air. Such sightings were the most common form of UAP documentation during the late 1940s, as the expansion of civilian and military aviation increased the number of eyes on the sky.
Under the current oversight of the All-domain Anomaly Resolution Office (AARO), all records released via the PURSUE program are designated as unresolved by default. The federal government maintains a neutral stance regarding the Jeffersonville incident, neither confirming that the object was anomalous nor concluding that it was a conventional phenomenon. The investigation remains open to various scientific and technological explanations prevalent to the 1940s.
Potential conventional candidates for such sightings include the presence of experimental aircraft undergoing testing, or the deployment of weather balloons, specifically those associated with the Project Mogul series which utilized high-altitude balloons to detect Soviet nuclear tests. Atmospheric optical phenomena, such as the formation of lenticular clouds or sundogs, can also create the illusion of moving, luminous objects. Furthermore, astronomical bodies like the Moon, Venus, or meteors appearing near the horizon are frequently cited as possible sources for unidentified aerial sightings during this period of history.
