The 1974 Coyame, Mexico UFO Crash

Overview

On August 25, 1974, US Air Defense radar detected an unknown object traveling at 2,200 knots at 75,000 feet altitude over the Gulf of Mexico, approaching US airspace before veering into northern Mexico and disappearing from radar screens near Coyame, Chihuahua, Mexico. According to the Denb Report—an anomalous document posted on early internet message boards in 1992 and anonymously mailed to UFO researchers—the object collided mid-air with a civilian aircraft departing El Paso for Mexico City. Mexican military forces located both crash sites but died under mysterious circumstances before they could return the recovered disc. A CIA-coordinated recovery team staged at Fort Bliss, Texas then covertly entered Mexican airspace, retrieved a 16-foot 5-inch silver disc weighing approximately 1,500 lbs, destroyed the Mexican convoy and bodies with high explosives to sanitize the site, and transported the object to Atlanta, Georgia.

The Coyame incident represents one of the most detailed alleged crash retrieval cases outside the United States, notable for its primary source document, the Denb Report, which provides minute-by-minute operational detail resembling classified military after-action reports. The case is referenced in MJ-12 Documents research, listed by the UAP Caucus as a case to bring before Congress, and corroborated by independent researchers including Leonard Stringfield, who heard of a US military cross-border retrieval in Chihuahua as early as the late 1970s. The deaths of the Mexican recovery team, the involvement of hazmat-equipped US personnel, and the rapid response from Fort Bliss evoke parallels with other alleged crash retrieval operations, including the 1997 Peru UFO Crash Retrieval involving Jonathan Weygandt.

The authenticity of the Denb Report remains contested. Ryan S. Wood, author of Magic Eyes Only, rates the case as medium to high authenticity based on the report's military terminology, operational detail, and consistency with known crash retrieval protocols. Key unanswered questions include the identity of "JS" (the report's author), the nature of the "DENB Team" (hypothesized to be an internal USG investigation group operating via early internet message boards), the cause of the Mexican personnel deaths, and the ultimate destination of the recovered disc.

The Denb Report: Primary Source and Provenance

The Denb Report first surfaced in 1992 on an electronic bulletin board under the title "Research Findings on Chihuahua Disc Crash," authored by an individual or entity identified only as "JS" and dated March 23, 1992. In early summer 1993, paper copies were anonymously mailed to UFO researchers including Elaine Douglas and Nick Redfern. Douglas shared the original documents with Leonard Stringfield, who reviewed the report and concluded it was "authoritatively written using correct military terminology" and, unlike hoaxes, drew clear distinctions between hard evidence and speculation.

The report is addressed to "all Denb team members" and designated "File UFO 3263," suggesting it is one of many UAP cases studied by this group. JS states the facts were "gathered from two eyewitness accounts, documentation illegally copied, and a partially destroyed document" by a now-deceased person in 1978. The notes and documents came into the hands of the DENB group in February 1992. The authorship and organizational affiliation of JS remain unknown. Hypotheses include "Joint Staff" or "Joint Services" as an acronym, or that JS represents an individual. The DENB Team itself is speculated to be an internal intelligence community investigation group analogous to the later UAP Task Force, which used Top Secret online forums to discuss UAP cases during the so-called "UAP Dark Ages" (1969–2007), the period between the closure of Project Blue Book and the creation of AATIP.

The star name "Deneb"—a highly luminous blue supergiant in the constellation Cygnus marking the beginning of the Milky Way's Great Rift—held significance to ancient stargazers, including southern Mexican shamans who referred to the rift as the "birth of all life." Whether this astronomical reference holds symbolic meaning for the DENB Team is unclear.

Radar Detection and Flight Profile

According to the Denb Report, on August 25, 1974, at 2207 hours, US Air Defense radar detected an unknown object approaching US airspace from the Gulf of Mexico at 2,200 knots, bearing 325°, altitude 75,000 feet. The object was on a course to intercept US territory approximately 40 miles southwest of Corpus Christi, Texas. After approximately 60 seconds, the object simultaneously decelerated to approximately 1,700 knots, turned to heading 290°, and began a slow descent. It entered Mexican airspace approximately 40 miles southwest of Brownsville, Texas.

The object was tracked by two different military radar installations for approximately 500 miles to a point near Coyame, Chihuahua, where it suddenly disappeared from radar screens. During flight over Mexican airspace, the object leveled off at 45,000 feet, then descended to 20,000 feet. Crucially, the descent occurred in level steps—each level maintained for approximately 5 minutes—not a smooth curve or straight line. This stepped descent profile ruled out a meteor explanation, as meteors travel at higher speeds and descend in smooth arcs.

An air defense alert was initially called, but before any interception could be scrambled, the object turned to a course that would not immediately take it over US territory. The alert was called off within 20 minutes. The object's point of disappearance was over a barren, sparsely populated area of northern Mexico. It was assumed the object had descended below the radar horizon; a watch was kept for reemergence, but none occurred.

Mid-Air Collision and Mexican Recovery Efforts

Approximately 52 minutes after the object disappeared from radar, civilian radio traffic indicated a civilian aircraft had gone down in the same area. The missing aircraft had departed El Paso International Airport with a destination of Mexico City; it could not have been the object tracked over the Gulf of Mexico, but both disappeared in the same area at approximately the same time.

By daylight on August 26, Mexican authorities began searching for the missing plane. At approximately 1035 hours, radio reports indicated wreckage from the missing civilian plane had been spotted from the air. Almost immediately came a report of a second "plane" on the ground a few miles from the first. Minutes later, an additional report stated the second "plane" was circular in shape and apparently in one piece, although damaged. Shortly thereafter, the Mexican military clamped radio silence on all search efforts.

The Denb Report speculates the collision occurred while the object was traveling at approximately 1,700 knots, suggesting significant impact force that "almost totally destroyed" the civilian light aircraft. The second area of damage on the disc—described as a "dent" about 2 feet wide—may have resulted when the object impacted the ground at considerably lower speed. No mention is made of the occupants of the civilian craft; given the destruction of the aircraft in mid-air, bodies may not have come down near the larger pieces.

Researchers Noah Torres and Ruben Uriarte, who co-authored Mexico's Roswell: The Chihuahua UFO Crash, believe the civilian aircraft was likely a Cessna 180 light aircraft, which has a service ceiling of 17,700 feet, consistent with the UFO's last radar detection at 20,000 feet. The authors speculate the aircraft may have been engaged in covert low-altitude drug smuggling operations. Anti-drug smuggling between the US and Mexico was a major issue in 1974; in an October 21, 1974 discussion between US President Gerald R. Ford and the Mexican president (just two months after the alleged crash), the Mexican leader stated, "along the 3,000 km border it is very easy for small planes to take off and land in small private ranches."

Torres and Uriarte reported that a Mexican newspaper, El Heraldo de Chihuahua, published a story on October 27, 1974, detailing the death of a group of Mexican soldiers in the crash of a "military transport." Mexican UFO researcher Alfonso Salazar is credited with locating this article. The authors also mentioned the August 1974 death of 50-year-old Mexican pilot Enrique Riviera Gutierrez, as reported in El Friso of Juarez, Chihuahua, though the connection to the Coyame incident remains speculative.

CIA Response and Recovery Team Assembly

Radio intercepts of the Mexican search efforts were reported through intelligence channels to the CIA. Possibly as many as two additional government agencies—speculated to include the NRO or NGA—also received reports, though this has not been confirmed. The CIA immediately began forming a recovery team. The Denb Report notes, "The speed with which this team and equipment was assembled suggests that this was either a well-rehearsed exercise or one that had been performed prior to this event."

Requests were initiated at the highest levels between the United States and Mexican governments that the US recovery team be allowed onto Mexican territory to "assist." These requests were met with "professional ignorance and a flat refusal of any cooperation."

By 2100 hours on August 26, 1974, the recovery team had assembled and been staged at Fort Bliss, Texas. Several helicopters were flown in from an unknown source and assembled in a secured area. The helicopters were painted a neutral sand color and bore no markings. Eyewitness descriptions suggest three smaller craft, very probably UH-1 Hueys, and one larger helicopter, possibly a CH-53 Sea Stallion. Personnel from the team remained with their craft and had no contact with other Fort Bliss personnel, suggesting compartmentalization and operational security.

The CIA's role in coordinating rapid UFO crash retrievals is corroborated by a September 2024 article by investigative journalist Christopher Sharp, who reported that the CIA's Office of Global Access (OGA) has played a central role in UFO crash retrieval since 2003, coordinating with Joint Special Operations Command (JSOC) and other agencies. Sharp's source stated the OGA acts as "a facilitator for people to get in and out of countries" and is "very clever at being able to get anywhere in the world they want to." The source added that while physical retrieval is done by the military, objects are moved out of military control "fairly quickly into private hands" because the military "has to keep too many records."

Intelligence on the crash site came from satellite and reconnaissance aircraft overflights. Satellite imagery likely came from the fleet of Keyhole spy satellites put into orbit around 1971, operated primarily by the NRO. Reconnaissance aircraft may have included assets from the El Paso Intelligence Center (EPIC), established at Fort Bliss in 1974, or an EP-3E reconnaissance aircraft, established in 1972.

Covert Recovery Operation

High-altitude overflights indicated that both the crashed disc and civilian aircraft had been removed from the crash sites and loaded onto flatbed trucks. Later flights confirmed the convoy had departed the area heading south. However, high-altitude overflights then indicated the convoy had stopped before reaching any inhabited areas or major roads. Reconnaissance showed no activity, and radio contact between the Mexican recovery team and its headquarters had ceased.

A low-altitude, high-speed overflight was ordered. The photos showed all trucks and jeeps stopped, some with doors open, and two human bodies lying on the ground beside vehicles. The decision was immediately made to launch the recovery team, but the actual launch was delayed for the arrival of additional equipment—presumably hazmat protection gear and high explosives—and two additional personnel, possibly munitions or decontamination experts.

At 1438 hours on August 26, the four helicopters departed Fort Bliss. They followed the border down to Presidio, Texas, then turned and entered Mexican airspace north of Candelaria. They were over the convoy site at 1653 hours. All convoy personnel were dead—most within the trucks, some outside.

Members of the recovery team dressed in bio-protection suits reconfigured the straps holding the object onto the flatbed truck, then attached them to a cargo cable from the Sea Stallion. By 1747 hours, the recovered object was on its way to US territory. Before leaving the convoy site, members of the recovery team gathered together the Mexican vehicles and bodies, then destroyed all with high explosives. This also included the pieces of the civilian light plane involved in the mid-air collision.

The use of high explosives to sanitize the site—destroying vehicles, bodies, and aircraft debris—suggests the recovery team was aware of contamination risks and sought to eliminate all evidence. Torres and Uriarte speculated the explosive used may have been an MK54 SADM (Special Atomic Demolition Munition) suitcase nuke, carrying the smallest yield of 10 tons. Such an explosive would effectively sterilize the site while keeping residual radiation effects and damage to the local population almost negligible. In his 2000 paper, Hans Krueger argued that fireballs from low-yield nuclear warheads can neutralize biological warfare agents, making this a plausible decontamination protocol.

At 1746 hours, the UH-1 Hueys departed. The Hueys caught up with the Sea Stallion as it re-entered US airspace. The recovery team then proceeded to a point in the Davis Mountains, approximately 25 miles northeast of Valentine, Texas. There they landed and waited until 0225 hours the next morning (August 27). At that time, they resumed flight and rendezvoused with a small convoy on the road between Van Horn and Kent, Texas. The recovered disc was transferred to a truck large enough to handle it and capable of being sealed totally. Some personnel from the Hueys transferred to the convoy. All helicopters then returned to their original bases for decontamination procedures.

Disc Description and Transport

The recovered object was described as follows:

• Diameter: 16 feet 5 inches
• Thickness: slightly less than 5 feet
• Shape: convex on both upper and lower surfaces to the same degree
• Color: silver, much like polished steel
• Features: no visible doors, windows, lights, or propulsion means; no markings
• Damage: Two areas of damage on the rim. One showed an irregular hole approximately 12 inches in diameter with indented metal around it, likely caused by the collision with the civilian aircraft. The other was described as a "dent" about 2 feet wide, possibly from ground impact.
• Weight: estimated at approximately 1,500 lbs, based on the effect of the weight on the carrying helicopter and those who transferred it to the truck

The Denb Report does not indicate whether anything was visible inside the hole or whether the disc was manned. Speculation about the cause of death of the Mexican recovery team included a chemical or biological agent released from the disc as a result of the damage. There are no indications of death or illness by any of the US recovery team, all of whom wore bio-protection suits when handling the object.

The convoy continued non-stop using back roads and smaller highways, staying away from cities. The destination of the convoy, according to the report, was Atlanta, Georgia. The reasons for this destination are unknown. However, Lockheed Martin operates a complex at Air Force Plant 6, located less than 30 miles outside of Atlanta in Marietta, Georgia. Lockheed's Skunk Works performs "advanced development" work at this location. The Lockheed Company had engaged in C-130 work in Marietta since the 1950s. Additionally, the Lockheed Martin Georgia Nuclear Aircraft Laboratory (AFP No. 67) served as Lockheed's lab for investigating the feasibility of nuclear-powered aircraft. The site was closed in 1971 and acquired by the city of Atlanta, but remains a plausible transfer point for exotic materials requiring specialized analysis.

One unconfirmed report says the disc was eventually transferred to Wright-Patterson Air Force Base. Another says the disc was either transferred after that to another unnamed base or was taken directly to this unknown base from Atlanta.

Deaths of the Mexican Recovery Team

The cause of death of the Mexican recovery team remains one of the most perplexing aspects of the case. The Denb Report states, "Unfortunately, what caused the deaths of the Mexican recovery team is not known. Speculation ranges from a chemical released from the disc as a result of the damage to a microbiological agent."

Some researchers have speculated that the US recovery team killed the Mexican soldiers to prevent them from returning with UAP debris. David Grusch has referenced multiple times that crimes have been committed to maintain UAP secrecy, and the destruction of the Mexican convoy and bodies with high explosives raises questions. However, the delay in departure for the arrival of additional hazmat equipment and specialists suggests the US team was aware of contamination risks beforehand, favoring the biological/chemical agent hypothesis over deliberate killing.

Parallels exist with other alleged contamination incidents documented in the MJ-12 Documents. The MJ-12 First Annual Report includes a passage in Section F ("Government Policy of Control and Denial") describing several Sandia National Laboratories personnel who came into contact with UFO debris and bodies. One technician collapsed while attempting to remove a body; one went into a coma for 4 hours when attempting to place a non-human intelligence body in a bag. All four technicians who suffered effects were rushed to Los Alamos, but all four died of seizures and profuse bleeding. Upon inconclusive autopsies, it appeared all four suffered from some form of toxin or highly contagious disease. The report states, "In the opinion of the senior Atomic Energy medical adviser, current medical equipment and supplies are wholly inadequate in dealing with a large-scale outbreak of the alien virus."

An IPU (Interplanetary Phenomenon Unit) summary report also discusses severe nervous breakdowns and suicides by military police, and states that "ground personnel from Sandia experienced some form of contamination resulting in the deaths of three technicians."

The biological contamination hypothesis is further supported by the testimony of Jonathan Weygandt, who described adverse mental effects—intense and unexplainable fear—when close to a crashed UAP in Peru in 1997. Weygandt's account also involved a CIA-coordinated recovery team arriving via CH-47 helicopters, with personnel in black fatigues and hazmat suits, strikingly similar to the Coyame case.

Whether the Mexican soldiers died from a toxic or biological agent released from the damaged craft, or were killed by the US team, remains unresolved.

Corroboration and Witness Testimony

Leonard Stringfield stated in 1994, "I heard of the Chihuahua case before, either in the late 1970s or early 1980s. The only detail I vaguely recall is that the US military team had covertly crossed into Mexico to retrieve the object." Stringfield presented "Retrievals of the Third Kind" at MUFON in 1978 and was reportedly warned circuitously by the CIA several days in advance that "it would be inadvisable for him to discuss crash information in Mexico or West Germany."

Noah Torres and Ruben Uriarte conducted field investigations in the Coyame region and reported witness testimony. In 2012, at a festival in Presidio, Texas, school teacher Johnny Chambers and her 10-year-old son (at the time) recalled seeing a strange fireball—a "big explosion in the sky"—on the Mexican side of the border near the Coyame area. The two initially thought a plane had crashed in the mountains. Within a day of the fireball, several residents observed a group of military helicopters traveling back into the US from the Mexican side, including a large twin-rotor helicopter. These witnesses came forward in 2012, five years after Torres and Uriarte's initial reporting, raising questions about whether they are false witnesses or legitimate corroboration.

Additional witnesses contacted Torres, including "Melissa P." (full name withheld), who stated on Facebook, "My uncle was ordered to go to the Mexico Roswell by the US military. He went, came back, and was never the same." Without names or further evidence, these accounts remain anecdotal.

Torres and Uriarte also reported finding alleged aircraft debris near the supposed crash site during their field investigation, though the forensic analysis of this material is not detailed in public sources.

The Wikipedia Mystery and "Mercy 11"

Since 2008, Wikipedia featured a brief report on the Coyame UFO crash referencing the Denb Report and Torres/Uriarte's Mexico's Roswell. In September 2012, user "Mercy 11" radically altered the article, adding names and intriguing details for the US recovery team and crash victims:

American recovery team (per Mercy 11):

• Captain Lawrence Mearley
• Lieutenant Randall Bishop
• Lieutenant Eduardo Ramirez
• Lieutenant Benjamin Rhodes
• Sergeant Terrence Miles
• Lieutenant Jerome Smith

All identified as "retired US Armed Forces personnel," suggesting the recovery team was not active military but experienced Private Industry seasoned operators.

Mexican soldiers (per Mercy 11):

• Captain Rogelio Arguello Gonzalez
• Sergeant Teofilo Margarito Puebla
• Corporal Jose Trinidad Marz
• Corporal Ricardo Velasquez

Mercy 11 stated the soldiers' "bodies displayed signs of death by asphyxiation."

Torres and Uriarte attempted to reach out to Mercy 11 to discover the source of this information. Mercy initially linked to a UFO Hunters episode titled "Unexplained Mexico's Roswell: The Coyame Crash," which did not contain any of this information. When pressed, Mercy 11 responded, "I suspect what happened is that I saw the information at some other site which I had on my screen at the moment but in another window which I failed to attribute and record properly."

Shortly after these 2013 correspondences, the entire Wikipedia page for the incident was deleted in 2014 by admin "Scotty Wong," who retired his account soon after. The entire Wikipedia page's existence and deletion is highly suspicious.

Research into the named individuals yields limited results:

• Captain Lawrence Mearley: One Utah-based individual left for the Armed Forces near the tail end of World War II; no rank or detail of service given.
• Lieutenant Randall Bishop: An Indiana man (1932–2020) who served in the Korean War as a war zone air traffic controller for the US Air Force while attending the University of Kentucky, then moved to Indiana to be a teacher. This is notable given the emphasis the alleged "Infographics Whistleblower" placed on the Korean War in UAP programs, and the significance of the general Indiana area.
• Lieutenant Benjamin Rhodes: Almost zero footprint outside of a famous US Civil War soldier. One modern reference exists in a 1989 issue of American Legion, identifying a Mr. Rhodes out of Delafield, Wisconsin, who served as a post commander, though it is unknown whether he was armed forces.
• Sergeant Terrence Miles: Referenced as Senior Chief Petty Officer Terrence Miles in the April 21, 1993 edition of the Guantanamo Bay Gazette, on active duty at the time. This contradicts Mercy 11's claim that all operators were retired US Armed Forces. However, it is possible Miles reenlisted, furthering his rank.
• Lieutenant Jerome Smith: If this is a misprint and the reference is instead to "Lieutenant Colonel Jerome Smith," a record exists of a deceased individual (2006) who served in the US Army in World War II and transferred to the US Public Health Service in 1970, achieving the rank of Commander before retiring in 1985.
• Lieutenant Eduardo Ramirez: A Private First Class Eduardo Ramirez served in World War II and earned a Distinguished Service Cross for bravery in destroying German machine gun nests with explosives and incendiaries. No record of promotion to Lieutenant can be found.

Whether these names are legitimate, partially accurate, or complete fabrications remains unknown.

Jesus Alberto and Alleged Video Evidence

On March 16, 2024, Jesus Alberto—a Mexican government official tasked with setting up UFO disclosure legislation and hearings, and intimately tied to the controversial "Nazca mummies"—posted a now-deleted tweet translated as: "I have the video. At your time, it's from another world." Context around the tweet suggested it referenced the 1974 Coyame incident.

UAP Gerb inquired whether Alberto was referencing the Coyame incident and whether he would share the video. Alberto responded with a thumbs-up about the video referencing the crash. Follow-up requests for access to the video, witnesses (military or civilian), or military documents on the case were met with no response. As of the video's publication, Alberto has not released the alleged video or provided any additional information.

Relationship to Fort Bliss and Philip J. Corso

Fort Bliss is mentioned by Colonel Philip J. Corso in his book The Day After Roswell. According to Corso, debris and bodies from the 1947 Roswell Crash were shipped to Fort Bliss, Texas. Fort Bliss was also the home of the El Paso Intelligence Center (EPIC), established in 1974, which could have been involved in gathering intelligence on cross-border UAP incidents.

Few other connections exist between Fort Bliss and UAP cases beyond a handful of Project Blue Book sightings. However, the Coyame case establishes Fort Bliss as a staging area for rapid cross-border retrieval operations, suggesting a longstanding role as a forward operating base for covert UAP recovery in the US-Mexico border region.

Forensic Analysis and Authenticity Assessment

Ryan S. Wood, author of Magic Eyes Only, rates the Coyame case as medium to high authenticity based on forensic document analysis. Wood considers the Majestic 12 Special Operations Manual to be among the most crucial pieces of the MJ-12 document set alongside crash retrieval case documentation. The Coyame case is referenced in MJ-12 research contexts and in the Eisenhower Briefing Document, which references crash retrieval cases and Sandia lab involvement.

Stringfield's assessment that the Denb Report is "authoritatively written using correct military terminology" and distinguishes between hard evidence and speculation supports the case for authenticity. However, the anonymous provenance, the mysterious identity of JS and the DENB Team, and the lack of corroborating government documentation remain significant obstacles to definitive authentication.

Inquiries to the FAA revealed no documents concerning the civilian aircraft crash, likely because it did not involve a US aircraft nor occur over US airspace. NORAD was suggested as possibly having space tracking records of the object's descent if it entered from orbital altitude, but no records have been released.

Key Unanswered Questions

• Who is JS? Is JS an individual or an acronym for a department such as Joint Staff or Joint Services?
• What is the DENB Team? Was it an internal USG investigation group analogous to the UAP Task Force, operating via early internet message boards during the "UAP Dark Ages"?
• What caused the deaths of the Mexican recovery team? Was it a biological or chemical agent from the craft, or were they killed by the US recovery team?
• Where is the disc now? Was it transferred to Wright-Patterson AFB, retained in Atlanta, or moved to another unnamed facility?
• Why was Atlanta the destination? Does this relate to Lockheed facilities, nuclear decontamination capabilities, or proximity to Sandia-related research?
• Are the names added by "Mercy 11" on Wikipedia legitimate? Can service records for the alleged US recovery team members be verified?
• What video does Jesus Alberto possess? Does he have reconnaissance aircraft overflight imagery, convoy footage, or other documentation?
• Did the disc enter from orbital altitude? If so, does NORAD have space tracking data?

Context Within UAP Crash Retrieval Discourse

The Coyame incident is contextualized within broader UAP crash retrieval discourse. It is listed by the UAP Caucus among crash retrieval events to bring before Congress. The case exhibits protocol elements consistent with other alleged retrieval cases:

• Rapid assembly and deployment of a specialized recovery team
• Use of unmarked helicopters with bio-protection suits
• Coordination by the CIA with possible involvement of JSOC, NRO, or other intelligence agencies
• Site sanitization with high explosives
• Transport to civilian aerospace contractor facilities rather than military bases
• Biological contamination risks requiring hazmat protocols

The parallels with the 1997 Peru incident involving Jonathan Weygandt—CIA coordination, CH-47 helicopters, hazmat suits, intense biological effects—suggest a consistent operational template for cross-border crash retrievals spanning at least two decades.

The Coyame case is frequently referred to as "Mexico's Roswell" and compared to internationally significant UAP incidents such as the Shag Harbour Incident in Canada and the Varginha Incident in Brazil, all of which involve alleged crash retrievals outside the United States with government involvement and witness testimony.
