FBI File 62-HQ-83894 Serial 153: "Flying Saucers" Photographed Over Oak Ridge, Tennessee, July 1947

In July 1947, W.R. Presley of 218 Illinois Avenue, Oak Ridge, Tennessee, photographed what the Knoxville News-Sentinel called a flying saucer. Presley had been photographing his family and house and used his last frame on a shot of a nearby mountain; when the roll was developed, a bright circular object appeared in that final image. The newspaper reported it as the first time a flying saucer had ever been photographed over Oak Ridge and noted that the picture had "all of Oak Ridge talking." The FBI Knoxville Field Office forwarded two prints and a photostatic copy of the newspaper clipping to FBI Headquarters under an Internal Security file.

James Tuck Correspondence: Green Light Sightings at Los Alamos, 1948,1951

A correspondent wrote to James L. Tuck at Los Alamos reporting several sightings of green lights in the Jemez Mountains between 1948 and 1951, typically between 9 and 11 PM, and one afternoon sighting of five objects flying in formation from southeast to northwest over Los Alamos. The writer directed Tuck to Protective Force logs as the record of times and dates, and named redacted Protective Force members as witnesses.

Senior USIC Officer Helicopter UAP Encounter Over Mountain Test Range

In late 2025, a senior U.S. intelligence officer and two pilots departed a Joint Operations Center by helicopter to investigate loud thuds and UAP sightings over a weapons test range. Hovering at 700 feet AGL, they observed countless orange orbs swarming near a mountain, then two large oval orbs stationary just above the rotor disk that expanded into a "T" formation of four or five before dimming over 10 to 15 seconds. Orange orbs also appeared directly above transiting fighter jets, matching their speed and flight path, and separately formed a triangle formation before vanishing.

CIA Intelligence Information Report: Unidentified Aerial Phenomenon at Sary Shagan Weapons Testing Range, USSR (1973)

A former Soviet citizen reported observing an unidentified sharp green circular object or mass in the sky over Site 7 at the Sary Shagan weapons testing range in the USSR sometime between November 1972 and November 1973. The source stepped outside while watching a Canada-USSR televised sports competition and saw the object to the west at approximately 70 degrees elevation; within 10 to 15 seconds the green circle widened and several green concentric circles formed around the mass, which faded within minutes with no associated sound. The source had no opinion as to what the phenomenon was, and there were no resultant rumors.

FBI 302: Senior US Intelligence Official's First-Hand Account of UAP Orb Encounter at US Military Facility

An FBI 302 interview, classified SECRET//NOFORN, documents a senior US intelligence official's first-hand account of a multi-hour aerial search at a US military facility in 2025. Personnel aboard a state partner helicopter observed a "super-hot" orb that came within ten feet of the aircraft before traveling an estimated 20 miles southeast at a speed the helicopter could not match. Over the following thirty minutes, crews observed a swarm of lights too many to count, and repeated formations of four to six oval orange orbs with white or yellow centers that flared up and down in sequence.

Apollo 11 Technical Crew Debriefing: Three Anomalous Observations (1969)

During the Apollo 11 Technical Crew Debriefing on July 31, 1969, Buzz Aldrin described three observations from the mission. Approximately one day from the Moon, the crew spotted an object of sizeable dimension that appeared L-shaped through the monocular and like a hollow cylinder through the sextant; ground control confirmed the S-IVB stage was 6,000 miles away, and the crew reached no conclusion about the object's size, range, or identity. Aldrin also reported recurring small flashes of light inside the darkened cabin, spaced roughly a minute apart, which he guessed were caused by some penetration of an object into the spacecraft.
