Pentagon records released on Friday detail unexplained aerial sightings around California's Catalina Island, including a silent silver object witnessed by three hiking Boy Scouts.
The accounts resurfaced in the Department of Defense's seventh public release of historical UFO files, documenting decades of military inquiries into strange phenomena along the Pacific coastline.
An Air Intelligence Information Report dated August 28, 1952, records the encounter of the three Boy Scouts during a mountain hike around noon on June 25 under clear skies. The youths reported watching a silent craft that appeared to move faster than a conventional jet aircraft before vanishing from view.
Boy Scout encounter at Camp Fox
According to the military intelligence document, the three Scouts were attending summer camp at Camp Fox on Santa Catalina Island when they witnessed the incident. The boys were hiking together in the same group along an island trail when the strange object appeared overhead.
"The object was silver in color, altitude is uncertain, and speed estimated to be faster than a conventional jet," the report states. Witnesses confirmed that the craft operated in complete silence, with the record noting that "there was no sound observed."
While the document remains sparse in technical detail, it notes that the object climbed into the air and executed an immediate turn before its "disappearance by disintegration." The boys watched the object vanish without leaving visible debris or wreckage.
Military evaluators noted significant gaps in the account. The report did not establish the craft's altitude or record the duration of the sighting, and the boys had no optical equipment or measuring instruments to verify what they saw.
The intelligence officer who compiled the report at March Air Force Base in Southern California acknowledged the difficulty of assessing the claims. "No estimate of the reliability can be attempted by the reporter," the document notes, adding that the experience of the young observers was "probably meager at best."
Santa Catalina Island lies roughly 22 miles south-southwest of the Los Angeles mainland coast, with Camp Fox operating as a long-standing youth camp along its shoreline. During the early Cold War, March Air Force Base served as a major regional centre for military intelligence units handling aerial defense inquiries.
Multiple sightings over Avalon
The Boy Scout report is not the only historical case linked to the island. Another file in the Pentagon release contains a handwritten letter dated May 1, 1949, describing two successive waves of unidentified objects over Avalon, the island's only incorporated city.
Avalon resident Percy E Mackey wrote the letter to describe an evening encounter that occurred on April 28. Mackey reported that his wife and a local schoolteacher had observed six objects passing overhead at around 8pm, flying "not in a group, but singly."
Minutes later, Mackey's wife walked over to their daughter's home on the next street. There, the woman, her daughter and her grandson saw four more objects traveling across the sky, with Mackey noting that all of them were "travelling in the same direction."
Mackey addressed his letter to Kenneth Arnold, the civilian pilot residing in Boise, Idaho, whose famous 1947 sighting near Mount Rainier in Washington state had popularized the phrase "flying saucer." In the years following his encounter, Arnold regularly received letters from members of the public reporting unexplained aerial sightings.
While Mackey's letter offered no details regarding the shape, color or speed of the craft, the resident expressed a willingness to assist. "If you are still interested in flying disks, saucers etc., please let me know and I will write more in full," he wrote.
Military reviews and missing sketches
The military intelligence file recording the Avalon incident shows that investigators summarised the event with notable discrepancies. Although Mackey's letter detailed ten separate objects across two sightings, the military summary recorded only six objects, noting that each flew past alone.
The official record listed no photographs or physical evidence to substantiate the sighting. Military reviewers ultimately concluded that there was "insufficient data for evaluation," leaving the report without a definitive explanation.
The file indicates that additional documentation originally accompanied Mackey's correspondence. The report lists four accompanying letters and notes that two of them included rough sketches illustrating what the witnesses observed over Avalon. However, those letters and drawings were not included in the Pentagon's Friday release.
During the late 1940s and 1950s, the United States Air Force evaluated thousands of civilian UFO reports through intelligence collection efforts that eventually became known as Project Blue Book. Incomplete witness reports that lacked supporting radar tracks or physical evidence were routinely shelved without follow-up investigations.
Submerged base theories and coastal investigations
The waters surrounding Santa Catalina Island and Southern California have long been a focal point for UFO enthusiasts and conspiracy theorists. In particular, some researchers have pointed to Sycamore Knoll, a vast, flat-topped underwater formation off the coast of Malibu, roughly 44 miles northwest of Catalina Island's western end, as the possible location of a hidden underwater alien base.
Other records in the Pentagon release demonstrate how military investigators resolved unexplained sightings along the California coastline by identifying natural phenomena. A November 1953 file details an account from a military witness in San Pedro, who reported watching a purplish-white light over Catalina Island for approximately 10 minutes.
The light initially appeared stationary before reportedly moving northwest toward Los Angeles. Following an inquiry, military investigators classified the sighting as astronomical, identifying the mysterious light as the planet Jupiter.
Another report from the island describes a civilian in Avalon who spotted a bright orange, circular object falling straight down on March 15, 1955. The entire sighting lasted roughly two seconds. Because of its brief appearance and downward trajectory, military analysts determined that the object was a probable meteor.
The release reflects ongoing efforts to make historical military files on unidentified anomalous phenomena available to the public. As more archives are opened, researchers and historians continue to review how defense officials handled unexplained reports from service members and civilians during the height of the Cold War.
