UFO Filmed From a Mexicana Airliner Over Oaxaca

Over the Salina Cruz region, Oaxaca, on the Tapachula to Mexico City air route · 21 September 2005 · Aviation encounter · Mexico

A real video still pulled from the witness's own footage, shot on 21 September 2005 through the window of a Mexicana de Aviacion airliner over the Oaxaca coast near Salina Cruz. A small dark object is visible in the sky over the coastline. This is the unannotated frame; a second published still rings the same object in red. The caption bar burned into the image reads "Ing. Carlos Cauich Carrillo 21/09/05 Mexico". Not a render or recreation; it is a frame from the original consumer camera clip.

On 21 September 2005 an engineer filming the coastline from a Mexicana de Aviacion jet over Oaxaca caught a small dark object that appeared to dart away from and back toward the airliner. The ten second clip, handed to investigator Ana Luisa Cid and circulated by the Institute of Hispanic Ufology, rests on one witness and no instruments, and stands unexplained.

What did witnesses see at Over the Salina Cruz region?

On the afternoon of 21 September 2005, at about 14:15 hours, an engineer named Carlos Cauich Carrillo was a passenger aboard a Mexicana de Aviacion commercial airliner flying the Tapachula to Mexico City route. The aircraft was over the Pacific coast near Salina Cruz, in the state of Oaxaca, at cruising height when he began filming the view through his window with a small Sony Cyber-shot DSC-P32 digital camera, a 3.2 megapixel pocket model. He said he was simply recording the landscape, the coastline and the sea far below, not expecting anything unusual.

According to the report compiled by investigator Ana Luisa Cid and translated for the Institute of Hispanic Ufology by Scott Corrales, the resulting clip runs about ten seconds. In it a small dark object appears in the sky outside the aircraft, below the wing line and against the hazy band where the coast meets the water. The object does not behave like fixed debris on the glass or a static speck. Cid described it as performing irregular movements at high speed, repeatedly vanishing from the frame and then reappearing, which she read as the object pulling away from the aircraft and then closing back in. Two still frames were pulled from the video and published with the case. In the first the dark shape sits alone over the coastline. In the second the same shape is ringed in red to draw the eye, sitting just inside the window frame against the brown coastal strip.

Both published stills carry a caption bar reading "Ing. Carlos Cauich Carrillo 21/09/05 Mexico". The object reads as a small compact dark mass with no visible wings, tail or contrail, seen at a distance through the curved cabin window. Given the stated cruising figures for the flight, roughly 800 kilometers per hour and about 12,000 meters, anything keeping pace alongside or darting away and back over a ten second window would have to be moving at a considerable speed of its own. That is the heart of what the witness and the investigator found striking: not a static dot, but something that appeared to move independently next to a jet airliner in level cruise.

The second published still from the same clip, with the dark object ringed in red. EXIF metadata shows it was exported with Windows Movie Maker 2.1.4026.0 on 6 October 2005, one day before the Inexplicata publication date.

What is the official explanation?

There is no official narrative for this event. No aviation authority, no airline incident report, and no government body is on record investigating it. Mexicana de Aviacion, the carrier named by the witness, did not issue any statement, and the airline itself ceased operations in 2010, so no corporate record was ever produced. There is no air traffic control transcript, no crew report, and no radar return associated with the sighting. The case never entered any official channel; it exists entirely as a passenger's personal recording handed to a civilian researcher.

The only documentary apparatus around the case is civilian ufology. The earliest traceable write up is the report assembled by Mexican investigator Profesora Ana Luisa Cid, a schoolteacher turned long time UFO researcher who has been collecting Mexican sighting footage since the late 1990s and whose English language case page, analuisacid.com.mx, was run in cooperation with Scott Corrales. Corrales, who directs the Institute of Hispanic Ufology and edits Inexplicata, translated and circulated the case in English. It carries the dateline "INEXPLICATA, The Journal of Hispanic Ufology, October 7, 2005" and was posted to UFO Casebook on 6 October 2005. Corrales routinely pushed these Hispanic ufology reports out through the UFO UpDates mailing list of the period, and the UFO UpDates archive shows him distributing a steady stream of Mexican airliner UFO reports in exactly these years.

Within that civilian framework, the technical commentary came from Alfonso Salazar Mendoza, an aviation technician and UFO researcher who supplied the baseline performance figures for a commercial airliner, roughly 800 kilometers per hour and a cruising altitude near 12,000 meters. Those numbers were offered not as a debunk but as a yardstick: if the object kept station with or maneuvered around a jet at that speed and height, then it was not a slow or stationary thing. No official body ever contested, confirmed, or attempted to explain the footage, which is why this case sits in the Unknown tier rather than Disputed. There is simply no counter narrative to weigh, official or otherwise.

What did the witnesses think it was?

The single named witness is the engineer Carlos Cauich Carrillo. He was filming the scenery through the cabin window and, by his own account, only realized later what the camera had caught. He described being left very nervous by the sequence, and he reached for an almost fated reading of it, telling the investigator that he felt as though "something or someone" had placed him in that exact seat at that exact moment so that he would record the event. That is the language of a man surprised by his own footage rather than someone presenting a prepared story, and it is the only first person interpretation on record.

There are no named corroborating passengers or crew, which is the chief evidentiary limit of the case. No flight attendant, pilot, or fellow traveler is quoted, and the aircraft registration and flight number were never published. The corroboration that exists is investigative rather than eyewitness. Ana Luisa Cid reviewed the original video and the two extracted stills and interviewed the witness, and she found the object's behavior, the repeated disappearance and return at speed, inconsistent with a smudge on the glass or a fixed mark in the frame. Alfonso Salazar Mendoza's contribution was to frame what kind of performance the object would need if it really was pacing the jet. Cid placed the clip among her September 2005 Mexican cases, the same batch of footage that the German research group CENAP later catalogued when surveying her site, which independently confirms that the case was logged and circulated at the time rather than invented after the fact. What the witnesses, meaning the witness and his investigators, believed was straightforward: a real object of unknown nature appeared alongside a passenger jet in level flight and was caught on a consumer camera by accident.

Is the UFO Filmed From a Mexicana Airliner Over Oaxaca real? The two-pass assessment

Pass one, the ordinary explanations, and they are numerous for a case like this. A small dark object filmed by hand through the curved, scratched, reflective double pane of an airliner window is the textbook setup for a mundane artifact. The leading prosaic candidate is a bird or an insect close to the glass, which against a distant coastline can look like a far object and which can dart in and out of a narrow handheld frame in a way that mimics high speed maneuvering. A second candidate is a speck of dirt, a water droplet, or a flaw on the window or lens that appears and vanishes as the camera pans and the focus shifts. A third is another aircraft or a high altitude balloon at distance, foreshortened into a featureless dark blob. The compression of a 3.2 megapixel 2005 pocket camera, the low resolution of the published 340 by 298 pixel stills, and the fact that the object is a near featureless dark mass all make any of these hard to rule out from the imagery alone. Crucially, the "irregular movement" can be partly or wholly an artifact of an unsteady handheld pan rather than true motion of the object. No independent analyst has ever stabilized the original video, measured the object's angular motion frame by frame, or checked it for parallax against the window frame, so the high speed maneuvering is an interpretation, not a measurement. None of this is a method shown debunk; it is a list of unexcluded ordinary possibilities, which is a different and weaker thing.

Pass two, if it is what it appears to be. If the object is genuinely out in the air and genuinely moving as Cid describes, pulling away from a jet at roughly 800 kilometers per hour and then closing back in within a ten second clip, then it is something performing at or beyond the speed of a commercial airliner at altitude, with no wings, tail, or contrail visible, which is the classic signature of the unexplained aerial object reported again and again from cockpits and cabins. This would put it in the same family as the better documented Mexican aviation encounters of the era, where pilots and instruments registered objects that paced or circled aircraft.

The honest verdict is that the case stands or falls on a single low resolution video that no qualified independent party has ever forensically analyzed, taken by one witness with no named corroboration, and never touched by any official body. There is no method shown discredit that would push it toward Disputed, and there is no authentication or official documentation that would lift it to Verified Unexplained. It rests entirely on its footage and its lone witness, with a clear and traceable chain of custody through Ana Luisa Cid and Scott Corrales but no instrumentation behind it. That is the definition of the Unknown tier: no official narrative exists, and the case lives or dies on the clip and the man who shot it.
