Overview
A recent review of historical UFO case files attributed to ufologist Noel E. Rigau and author Santiago Garcia revisits a reported wave of sightings in Puerto Rico during 1973, with additional accounts from Mexico. The cases include alleged close encounters, formations of luminous objects and reports of unusual aerial maneuvers. The accounts are presented as historical testimony rather than independently verified evidence, and the available material does not establish whether the objects were aircraft, astronomical phenomena or something else.
According to the review, activity in Puerto Rico intensified in November, although earlier incidents were also recorded. One of the most striking reports involved a group near El Yunque, Puerto Rico’s Caribbean National Rainforest. In the account, witnesses described a close encounter involving a humanoid presence. The source provides limited detail about the incident in the material reviewed, but places it among the events that preceded the November wave.
Reports From Puerto Rico
One of the earliest detailed cases occurred in Mayagüez, where photographer William Rosario reportedly captured an image of an unidentified object during daylight. Four people were said to have witnessed the sighting. The review describes the photograph as notable, but does not provide technical information such as the camera used, the original negative, the object’s estimated distance or an independent photographic analysis.
Other Puerto Rican cases were reported in early November. In the Piña neighborhood of Toa Alta on November 2, witnesses allegedly saw an oval object flying low and almost silently, with a “silvery phosphorescence.” The account says an apparently human pilot, wearing an unusual helmet and goggles, waved or gestured before the object hovered and then turned sharply north. Witnesses also reported finding warm, ash-like dust at the site, although the source states that no sample was obtained for examination. Later that evening, Andrés Acevedo reportedly saw another object traveling north, with two lights and what he described as “antennas.”
A Concentrated Wave of Sightings
The reports continued across the island. On November 9, biology teacher Edwino Lebrón Lebrón said he observed two luminous discs flying rapidly from west to east in what he characterized as a military formation. The following night, dozens of people in Maricao reportedly watched a bright, rotating object that appeared to emit “flames of fire” for approximately 15 minutes.
On November 11, several reports emerged around San Juan. Young people at El Morro allegedly saw six round objects moving south toward Cataño, each with a red light above it. Around the same time, Ana Soldevilla and her family reported a luminous object that initially resembled a star but remained stationary for about five minutes while displaying numerous twinkling lights. Guillermo Gandía and family members described another motionless oval object in the Sagrado Corazón area, this one reportedly marked by a row of small lights along its lower edge.
Accounts From Mexico and Historical Context
The review also references a report near Chihuahua City, Mexico, where witnesses allegedly observed a luminous object for roughly 45 minutes. The object was said to descend before accelerating away, a sequence that made the case noteworthy in the collection. As with the Puerto Rican reports, the available account does not provide independently corroborated radar data, physical evidence or a formal investigation that would resolve the object’s identity.
Taken together, the cases illustrate the kinds of testimony that shaped UFO investigations in the 1970s: multiple witnesses, unusual lights and movements, alleged physical traces and occasional photographs. However, the reports remain historical claims attributed to Rigau and Garcia. No conclusion about extraterrestrial technology or other extraordinary explanations can be drawn from the accounts alone, particularly without preserved evidence, documentation and independent analysis.
