Las Vegas, Nevada UFO Sighting (December 27, 1948) — FBI Files
A machinist recorded film of a winged, jet-propelled flying disc near Las Vegas, Nevada, in December 1948, according to declassified FBI documents.
Historical Context
The late 1940s represented a period of intense fascination and growing anxiety regarding unidentified aerial phenomena across the United States. Following the June 1947 Kenneth Arnold sighting and the subsequent July 1947 Roswell incident, the American public and government agencies were confronted with a sudden influx of reports involving “flying saucers.” This era was characterized by the early stages of the Cold War, a time when the rapid advancement of aerospace technology and the emergence of high-altitude surveillance capabilities created a landscape of heightened atmospheric scrutiny. During this period, many sightings were analyzed through the lens of potential Soviet technological breakthroughs or experimental domestic aeronautics.
The geographic setting of the Las Vegas region in 1948 was increasingly significant to national security. As the United States expanded its military footprint in the American Southwest, the presence of sensitive installations and testing ranges necessitated rigorous monitoring of the airspace. Because of this, the Federal Bureau of Malaysia (FBI) maintained established protocols for the protection of vital installations. When reports of unidentified objects surfaced, field offices in locations such as Knoxville, Albuquerque, and Los Angeles were instructed to route such intelligence to headquarters to ensure that any potential threats to national infrastructure were properly documented and evaluated.
The December 1948 Incident
On December 27, 1948, an incident occurred near Las Vegas, Nevada, that would eventually be documented within the official records of the FBI. The primary witness to the event was Lonnie Noack, a machinist by trade. Noack reported the sighting of an unidentified object that he believed could be captured on film. The resulting documentation, which was later released to the public on May 8, 2026, as part of the Presidential Unsealing and Reporting System for UAP Encounters (PURSUE), provides a specific physical description of the craft.
According to the records, the object was approximately eight feet in diameter. Noack described the craft as possessing a tail and wings, and he noted that it appeared to be equipped with jet propulsion. To support his claim, Noack provided FBI agents with a 50-foot roll of film. Upon examination, the agents identified approximately fifteen feet of footage that appeared to be related to the disc. While the document provides a detailed description of the object’s physical characteristics and the nature of the film evidence, the total number of witnesses present during the sighting is not specified in the released file.
Analytical Framework and Classification
The Las Vegas case is categorized as a sighting involving photographic or video evidence, a feature that distinguishes it from many purely anecdotal reports of the era. The presence of physical media, even in limited quantities, often moved such cases into a different tier of investigative priority for federal agencies. However, the status of the footage remains officially unverified in terms of its origin or the exact nature of the object depicted.
Under the current oversight of the All-domain Anomaly Resolution Office (AARO), all records released through the PURSUE program are designated as unresolved by default. The federal government maintains a neutral stance, having neither concluded that the event was caused by anomalous phenomena nor that it was the result of conventional technology. In the context of the late 1940s, investigators often considered several conventional candidates for such sightings. These included experimental aircraft being developed by the military, weather balloons—specifically those associated with the Project Mogul series—and various atmospheric optical phenomena such as lenticular clouds or sundogs. Additionally, astronomical objects like the Moon, Venus, or meteors appearing near the horizon were frequently cited as possible explanations for reported unidentified objects.
