In the vast expanse of Mexico’s night sky, rectangular-shaped UFOs defy explanation, captivating skywatchers and scientists alike as a relatively newly reported shape of unidentified aerial craft. Gliding silently with ethereal grace, these celestial visitors leave a trail of wonder and speculation in their wake. Witnesses grapple with profound mysteries beyond earthly understanding, sparking curiosity and the relentless pursuit of truth. In this episode of Mexico Unexplained, we will take a look at some of the most famous sightings of rectangular-shaped UFOs spotted over Mexico.
One of the earliest reported sightings of the unusual rectangle shaped UFO in the skies over Mexico was in the early morning hours of January 9, 1999, at approximately 2:40 in the morning. A single observer working outdoors on the U.S. side of the border near Tijuana, Mexico, witnessed a brief anomalous light under exceptionally clear Santa Ana conditions. A white flash resembling a meteor traveled from east to west over the southern hills of Tijuana, then halted for roughly one second and resolved into a green rectangle with rounded corners that emitted a bright green light and appeared fuzzy or hazy. After that brief pause the object accelerated rapidly at an upward angle toward the east, returning to a white flash and vanishing. The entire event lasted only two to three seconds. The witness, a college graduate, US military veteran, and pilot, later noted that the sighting aligned with earlier reports of UFO activity over Tijuana that had been discussed on the Art Bell radio program; those accounts had previously been dismissed because the observer regularly worked in the area and had seen nothing unusual until that night.
On April 23, 2006, while vacationing with family on the Riviera Maya and exploring the ancient Mayan ruins at Tulum, Mexico, a father and his oldest son spent the morning photographing the site on a relatively quiet Sunday when most visitors were locals. Later that day the group swam at the nearby beach. The following day at their hotel, the father overheard local workers discussing UFO sightings along the coastline near Tulum. After returning to the United States and reviewing their digital photographs, the father noticed a small speck in the corner of one image; when enlarged, the rectangular object initially resembled a helicopter, yet no aircraft had been seen or heard during the peaceful visit. At an even larger size this possible helicopter had a distinctive rectangular shape. The underside of the object displayed a glow and appeared to be oscillating. The father, who described himself as somewhat skeptical, could not account for the object’s appearance or the coincidence that locals had reported UFO activity on the same day the photograph was taken. His oldest child has repeatedly urged that the image be submitted to a UFO reporting site or examined by a professional photographer.
On October 15, 2012, around 3:30 a.m., two observers driving from Acapulco toward Mexico City on the road through Parres, between Mexico City and Cuernavaca, encountered a large rectangular object hovering statically about 300 feet above the roadway and roughly 250 feet to the north. The gray, metallic-looking craft was estimated as measuring 300 feet across, with small lights around its perimeter and two open doors underneath from which energy was visibly emerging, along with an aura or haze. Due to its proximity and scale, it appeared exceptionally clear; the driver felt a strong sense of unease and a “bad energy,” stopped the car short of passing beneath it, and remained halted for the 30 to 50 seconds the object stayed motionless in the sky. After that interval the craft began moving slowly eastward at an estimated 50 miles an hour toward the right side of the road. Roughly a minute later it reached a nearby mountain and disappeared behind it, leaving only the energy still visible. The driver then accelerated and continued the journey. The entire encounter lasted approximately two minutes. The primary witness later told investigators of having previously expressed a desire to be abducted and meet extraterrestrials. However during the sighting he felt the craft’s occupants might be greys or an unfriendly race, so he offered an apology to God and the universe. Neither observer in that car had ever seen a photograph, video, or known military vehicle matching the object.
On the morning of July 23, 2023, two observers on an oceanfront patio roughly fifteen feet from the Caribbean shoreline in Mahahual, Quintana Roo, Mexico, reported seeing two large rectangular objects, each estimated at eight to ten feet in size, flying in sequence at approximately one hundred feet altitude and fifty to seventy miles per hour along a southeast trajectory. Within about a second of being noticed, each object came to an abrupt dead stop with no visible deceleration, propulsion, or lift, then dropped vertically into the water in a straight-down trajectory that produced no angled splash, water disturbance from thrust, smoke, or heat. Birds had already begun flying away from the objects’ path before the witnesses spotted them. Later the same day, around 6:08 p.m., a third similar rectangular object was observed much closer, only five to six feet above the sea surface roughly one hundred meters offshore; it likewise stopped instantly and dropped straight down with a “kaplunk” sound and a distinctively symmetrical splash. Almost immediately afterward, an identical splash and sound occurred in precisely the same location, which the primary witness interpreted as a fourth event that had not been visually seen and that appeared improbably perfect given the slight surface waves. The witness, who described himself as having a photographic memory and extensive background in technology, projection systems, and flight, concluded that only three objects had been observed and that the repeated, identical entry characteristics, absence of physical effects, and instantaneous stops strongly suggested advanced projection or holographic technology rather than solid craft. The events lasted only three to five seconds each, and both observers happened to step onto the patio and look seaward within seconds of every occurrence, both in the morning and again eleven hours later, without having spent other time watching the water that day. Their report to investigators further noted that the same pair had witnessed several other physics-defying incidents in the area over the preceding six years, including meteors that changed direction or struck the water. The primary witness expressed the view that the objects appeared designed to vanish upon being seen, possibly to limit reaction or reporting time, and stated that the pair had not yet investigated the splash locations underwater.
On the evening of September 19, 2024, around 7:00 p.m. in the colonial heart of the city of San Miguel de Allende, Guanajuato, Mexico, a single observer was examining a trimming job on a tall tree when a large, square-shaped silvery object became visible high in the clear, cloudless blue sky. The craft appeared nearly overhead at an elevation of roughly 87 degrees, estimated at less than 2,000 feet away, and seemed almost stationary and completely silent, with no lights or other markings. It remained in view for only about five seconds before sliding behind the roof of the house and out of the line of sight. The witness immediately ran into the yard and then up to the rooftop in an attempt to relocate the object, but it had vanished. A few days later a friend shared a photograph taken by another person at approximately the same time and on the same day, which the witness found unusual. The observer later spoke to an American UFO investigator and submitted an updated report that included a personal drawing of the rectangular craft and additional logistical details, confirming the object’s brief, silent presence against the empty late-afternoon Mexican sky.
Across these five independent reports spanning more than two decades and multiple regions of Mexico, a consistent and statistically uncommon pattern emerges: the repeated observation of large, rectangular or square-shaped objects exhibiting anomalous flight characteristics. From the 1999 Tijuana event in which a white flash resolved briefly into a green rounded rectangle, through the 2006 Tulum photograph, the massive 2012 craft hovering over the Mexico City–Cuernavaca highway, the 2023 Mahahual objects that stopped and dropped vertically into the Caribbean, and the 2024 San Miguel de Allende square that vanished behind a rooftop, each case describes a geometric form that is markedly rare in the broader UFO literature. While discs, spheres, triangles, and cigar shapes dominate historical databases, rectangular craft appear in only a small fraction of reports; their repeated occurrence along the Mexican coast and highlands, often accompanied by silence, abrupt stops, haze or energy emissions, and the absence of conventional propulsion signatures, therefore stands out as a noteworthy regional anomaly worthy of further scrutiny.
