The Roswell Incident: The 1947 Crash That Started Modern UFOlogy.

The Roswell incident is the case that produced the entire framework of modern UFOlogy — the witness reversals, the document leaks, the rotating official explanations, the museum, the souvenir industry, and the ongoing federal disclosure debate of 2023–2026. What it actually consists of, in primary documents, is small: a rancher's recollection, a single-edition newspaper headline, a one-day Army press release and its next-day retraction, a set of Fort Worth photographs, an 18-page 1994 federal report, and approximately 30 sworn or contemporaneously-recorded witness statements collected across half a century. Around that primary record, decades of investigation have built up. The shape of what is verifiable — and what is not — is what this page sets out.

Where it started — June and July 1947

The chronology starts roughly three weeks before the famous press release. William W. "Mac" Brazel (1899–1963) was the foreman of the J.B. Foster Ranch, a sheep operation roughly 75 miles northwest of Roswell, in Lincoln County, New Mexico. Foster himself was not on the property; Brazel managed the ranch with his wife and children. Brazel later recalled the discovery as having occurred on or near June 14, 1947: he and his young son had been riding the ranch following a thunderstorm and came upon a debris field of unusual material — metallic foil-like sheets that he later reported would not tear, would not burn, and would resume their original shape after being crumpled; thin beam-like material with markings that resembled hieroglyphics; and rubber-like fragments scattered across approximately three-quarters of a mile.

Brazel did not initially report the find. He had work to do. The relevance of the debris changed on June 24, 1947, when Idaho pilot Kenneth Arnold reported sighting nine crescent-shaped objects flying near Mount Rainier in Washington State at high speed. Arnold's account, given to a local newspaper that afternoon, introduced the term "flying saucer" into American English and produced — over the following six weeks — a national wave of similar reports across most of the continental US. Brazel, hearing about the saucers, began to wonder whether the debris on his ranch might be related. On July 7, 1947, he drove into Roswell and reported the find to Chaves County Sheriff George Wilcox. Wilcox contacted the Roswell Army Air Field.

The base sent Maj. Jesse A. Marcel Sr., the 509th Bomb Group's intelligence officer, and Capt. Sheridan Cavitt of the Counterintelligence Corps. They drove to the Foster Ranch with Brazel, examined the debris field, collected as much material as they could, and returned to RAAF on July 8.

The 24-hour news cycle that produced the case

What happened on July 8, 1947 is the single most consequential 24-hour period in the history of American UFO discourse. The morning of that day, RAAF public information officer Lt. Walter Haut, on instructions from base commander Col. William "Butch" Blanchard, drafted and released a press statement to local Roswell media. The statement read in part: "The many rumors regarding the flying disc became a reality yesterday when the intelligence office of the 509th Bomb Group at Roswell Army Air Field was fortunate enough to gain possession of a disc through the cooperation of one of the local ranchers and the sheriff's office of Chaves County."

The Roswell Daily Record's afternoon edition of July 8, 1947 carried the announcement on the front page under the headline "RAAF Captures Flying Saucer On Ranch in Roswell Region." The Associated Press picked up the story on the wire that evening. Within hours, newspapers across the United States were carrying the announcement.

Then it was retracted. By that evening, Marcel had been ordered to fly the debris from Roswell to Fort Worth Army Air Field, headquarters of the 8th Air Force, where Brig. Gen. Roger Ramey took control of the materials. On the morning of July 9, 1947, Ramey held a press conference in his office at Fort Worth, with Marcel present, in which he announced that the recovered material was the remnants of an ordinary weather balloon. Photographs of Marcel and Ramey posing with the substituted material — clearly identifiable balsa-strut, foil, and reflector components — were released to the press and widely distributed. The Roswell Daily Record's July 9 evening edition carried the new version under the headline "General Ramey Empties Roswell Saucer." The case, in mainstream press terms, was over within 36 hours.

It would not be revisited in any serious public way for thirty years.

The 1978 Marcel reversal

In 1978, nuclear physicist Stanton T. Friedman (1934–2019), then a lecturer on UFO topics at college campuses across North America, was given Maj. Jesse Marcel's contact information by a Louisiana ham-radio operator who had been making conversation with the now-retired officer. Friedman called Marcel. The two spoke at length. Marcel, then 71, agreed to be interviewed on the record.

What Marcel said in 1978–1979 was the foundation of every subsequent line of inquiry into the case. He stated, in interviews recorded variously by Friedman, by William L. Moore, and by the BBC's Nationwide program: that the debris he had collected at the Foster Ranch was unlike any material he had encountered in his Army intelligence career; that the foil-like sheets did not behave like aluminum foil and could not be cut, dented, or burned; that the beam-like elements bore symbols he could not identify; that the press conference at Fort Worth had used substituted material; and that, in his judgment, what he had recovered was "not anything from this Earth." Marcel was an experienced wartime intelligence officer who had received the Air Medal and three battle stars during the European theater. His reversal, more than thirty years after the event, did not produce additional documents — but it did produce a witness whose military credentials made the case impossible to ignore.

Marcel's son, Jesse Marcel Jr., was 11 years old in July 1947. He recalled, in interviews recorded from the late 1970s onward, that his father had brought several pieces of the debris home in the early hours of July 8 before delivering them to the base, and had laid the material out on the kitchen floor for him and his mother to examine. Marcel Jr.'s independent recollection of the foil-like material and the symbol-bearing beams matched his father's account. Marcel Jr. became a flight surgeon and later served as the Iraq Surgeon for the Montana Army National Guard. He gave a sworn deposition in 2010, the year before his death, restating his recollection in detail.

What the theory claims

The Roswell case is, more than almost any other case in this catalog, a question about what the documents say versus what the witnesses say. The documents say one thing — Mogul balloons. The witnesses, taken across the full half-century span of the case's investigation, say something else. The central thesis researchers have built is not that the documents are wrong on their face. It is that the documentary record is incomplete in a way that is itself the evidence.

The argument runs as follows. The Roswell Army Air Field's 509th Bomb Group was in July 1947 the only nuclear-weapons-armed bomber unit in the United States military and the highest-classified active combat unit in the country. The Group's intelligence officer, Marcel, had been read into the relevant local programs and had handled classified material continuously for years. The proposition that this unit's intelligence officer would issue, with base-commander approval, a public press release announcing recovery of a "flying disc" — and then both that officer and the base commander would within 24 hours be photographed with substituted weather-balloon material in front of national press — describes either a catastrophic failure of military information discipline or a deliberately staged retraction. Either reading raises questions the official Mogul explanation does not by itself answer.

Researchers further note that Project Mogul's existence as a classified program does not, on its own, account for the witness testimony collected from non-RAAF personnel beginning in the late 1970s. Brazel's late wife and children gave separate accounts. Glenn Dennis, a Roswell mortician, recalled receiving an unusual call from the base in 1947 inquiring about availability of child-sized caskets — an account he repeated consistently from his first 1989 interview through his 2015 death. Frankie Rowe, daughter of a Roswell fire department officer, recalled her father bringing home an account of small bodies recovered at a separate impact site. Loretta Proctor, a neighbor of Brazel's, recalled handling a piece of the debris Brazel had brought to her family. None of these witnesses had any apparent reason to fabricate. None of them had been in contact with each other before being interviewed. The official Mogul-and-crash-test-dummies explanation, researchers argue, accounts for the foil but not for the people.

The most-developed framing, advanced by Friedman in his 1980 book with William L. Moore and continued in Donald Schmitt and Tom Carey's 2007 Witness to Roswell, holds that two separate crash sites were involved — the Foster Ranch debris field and a separate impact site at which bodies were recovered — and that the weather-balloon press conference was a deliberate cover story designed to redirect public attention from the second site. Annie Jacobsen's 2011 Area 51: An Uncensored History advanced an alternative reading in which the recovered material was Soviet-Horten Brothers experimental aircraft carrying surgically-altered humans — a thesis Jacobsen attributes to a single retired EG&G engineer source, and one that other Roswell researchers have rejected as inadequately corroborated.

The 1994 Mogul disclosure and the 1997 follow-up

By the early 1990s, the Roswell case had returned to mainstream American politics. Congressman Steven Schiff (R-NM), whose district included Roswell, requested a formal General Accounting Office investigation in early 1993. The GAO opened its inquiry and issued its report on July 28, 1995. The report's primary finding was that essentially all relevant Air Force administrative records from Roswell Army Air Field for the months of March, April, and May 1947 had been destroyed at some point during the 1950s through unspecified routine procedure, with no documentation of the authorization or process. The GAO's secondary finding was that the Air Force had recently completed its own internal investigation, the results of which were the September 1994 USAF report.

The September 1994 USAF report, prepared by Col. Richard Weaver of the Air Force Office of Special Investigations, identified the recovered material as Project Mogul debris — specifically Flight #4, launched June 4, 1947 from Alamogordo Army Air Field, which had been tracked across central New Mexico and lost in approximately the Foster Ranch area. The report acknowledged that Project Mogul had been classified at a level above Maj. Marcel's local clearance and that base-level personnel could plausibly not have been briefed on the program's existence. The report's primary author for Project Mogul technical details, Charles B. Moore, was the surviving senior NYU Constant Level Balloon Group physicist and one of Mogul's original principal investigators. Moore supported the identification.

The June 24, 1997 follow-up report, "The Roswell Report: Case Closed," addressed the alleged "alien body" witness accounts. The report's conclusion was that witness recollections of small-stature bodies recovered in the Roswell area were chronologically displaced memories of crash-test dummies dropped by the Air Force in the New Mexico desert during high-altitude testing programs between 1953 and 1959. Researchers noted that this conclusion required moving the witnesses' memories forward by six to twelve years and unifying the recollections of multiple separate witnesses around a substantially different program. The report acknowledged this as a known limitation of the explanation.

The 1995 Santilli alien-autopsy footage

In May 1995, British music producer Ray Santilli announced that he had acquired approximately 17 minutes of black-and-white 16mm film footage purportedly showing a US Army medical autopsy on a small humanoid creature recovered from a 1947 New Mexico crash site. Santilli stated that the footage had been provided to him by an unnamed retired US Army cameraman. The footage was first broadcast in the United States on August 28, 1995 in the Fox television special "Alien Autopsy: Fact or Fiction?", hosted by Star Trek: The Next Generation actor Jonathan Frakes. The broadcast generated international coverage and several follow-up productions across multiple countries.

In 2006, in the British Channel 4 documentary Eamonn Investigates: Alien Autopsy, Santilli publicly stated that the released footage was a "reconstruction" rather than the original 1947 material. He maintained — and continues to maintain — that he had been shown genuine 1947 footage that had degraded by the time he attempted to release it, and that the released footage was a reproduction created with the assistance of British sculptor and special-effects artist Spyros Melaris using a latex body cast. The original footage Santilli claims to have seen has never been produced. Most Roswell researchers now treat the Santilli footage as a hoax.

The case's interpretive position is that the Santilli affair is, by itself, evidence neither for nor against the underlying Roswell incident. What it illustrates is the case's susceptibility to opportunistic fabrication — and the parallel difficulty of independently verifying any non-government primary documentation that has emerged in the decades since 1947.

The Walter Haut affidavit

In December 2002, Lt. Walter Haut — the original public information officer who had drafted the July 8, 1947 RAAF press release — signed a notarized affidavit, witnessed by Roswell attorney Patrick V. Powers and sealed until after Haut's death. Haut died on December 15, 2005. The affidavit was released in 2007 by Donald Schmitt and Tom Carey, and incorporated into their book Witness to Roswell.

The affidavit's content went substantially beyond what Haut had stated publicly during his lifetime. Haut declared in writing that he had personally been shown the recovered craft at "Building 84" on the base on July 8, 1947, in the presence of Col. Blanchard, and that he had observed the craft to be approximately twelve to fifteen feet long, six feet wide, and roughly egg-shaped. He stated that he had seen two small bodies under a tarpaulin. He stated that the press release he had issued — declaring recovery of a flying disc — had been the original cover story, and that the subsequent weather-balloon retraction at Fort Worth had been the second cover story; both, in his account, were intentional. The affidavit's release reopened the case in independent research circles. The official US government position has not been revised.

The variations within the broader thesis

Roswell is one of the few cases in this catalog where genuinely distinct sub-camps among researchers have formed. The differences are about what was recovered.

The extraterrestrial-craft variation is the most popularly held and the one most directly continuous with the witness statements collected from 1978 through 2007. It holds that what crashed at one or more sites in the Foster Ranch area in early July 1947 was a vehicle of non-human origin, that the debris collected by Marcel was material of unknown manufacture, and that small humanoid bodies were recovered from a separate impact site. The cover story — Mogul balloons — is read on this view as a true but partial statement: Mogul was real, Mogul was classified, and Mogul provided the institutional cover for a more sensitive recovery operation.

The Mogul-only variation is the official US government position and the position of physicists including Charles B. Moore. It holds that what was recovered was a balloon array carrying acoustic sensors, that Marcel and the 509th personnel were not briefed on the program's classified nature, and that the witness reversals collected decades later are products of memory contamination, social influence among researchers in regular contact, and conflation of the 1947 events with later 1950s test programs.

The Soviet-or-terrestrial variation is the smallest of the three and is most prominently associated with Annie Jacobsen's 2011 work. It holds that the recovered material was an experimental Soviet aircraft of Horten Brothers design (the wartime German flying-wing designers, several of whom were captured by Soviet forces), and that small bodies recovered at a separate site were surgically-altered teenagers being used by Stalin in a psychological-warfare operation against the United States. Jacobsen's reading depends on a single retired-engineer source. Most other Roswell researchers reject the variation as inadequately documented.

The connections people make

Roswell sits at the origin of modern UFOlogy and is therefore connected, at least loosely, to essentially every subsequent UAP case. The four adjacencies most commonly drawn by independent researchers are these.

The most direct adjacency is to the Bob Lazar / Area 51 disclosures of 1989. Lazar's 1989 KLAS-TV interviews with reporter George Knapp described his alleged work at the S-4 facility on retro-engineering recovered craft. Lazar specifically claimed that nine craft were stored at S-4, and the storage of non-domestic craft at Nevada Test and Training Range facilities is, in independent research circles, the most-cited continuation of the operational structure researchers infer began at Roswell in 1947. The Wright-Patterson Air Force Base "Hangar 18" tradition — which holds that recovered craft were transferred from Roswell to Wright Field in Ohio in mid-July 1947 — is the connecting tissue between the two cases.

A second adjacency is to the Phoenix Lights mass sighting of March 13, 1997 — the case in which thousands of witnesses across multiple states observed a V-shaped formation moving silently across Arizona, and in which then-Governor Fife Symington publicly mocked the public's concern at a 1997 press conference before reversing himself in 2007 and stating he had personally witnessed the formation. The Phoenix Lights and Roswell are connected as bookends of the modern UAP era — Roswell as the case that produced the framework, Phoenix Lights as the case that demonstrated the framework continued to be operative fifty years later.

A third adjacency is to Skinwalker Ranch, the 480-acre property in Utah's Uintah Basin that was studied by Robert Bigelow's National Institute for Discovery Science from 1996 onward and by Bigelow Aerospace's BAASS contract with the Defense Intelligence Agency's Advanced Aerospace Threat Identification Program (AATIP) from 2008 onward. The Skinwalker case is the most-documented sustained anomalous-phenomena field site of the post-1947 era; researchers connect the two cases as showing that whatever Roswell represented institutionally has continued to receive ongoing classified attention.

A fourth adjacency, more methodological than topical, is to Project Stargate — the CIA / Defense Intelligence Agency remote-viewing program that ran from 1978 through 1995 at SRI International and Fort Meade. The connection independent researchers draw is that the same federal apparatus that has, on the public record, run a 17-year remote-viewing research program is the apparatus whose Roswell-related records were destroyed without authorization in the 1950s. The willingness to fund the first is read as relevant context for assessing the latter.

The official position

The United States government's formal position is that the debris recovered from the Foster Ranch on July 7–8, 1947 was the remnants of Project Mogul Flight #4, a top-secret high-altitude balloon array launched June 4, 1947 from Alamogordo Army Air Field for the purpose of detecting Soviet atomic-bomb tests by acoustic monitoring of the upper stratosphere. The 1994 USAF report by Col. Richard Weaver established this position; the 1997 follow-up report addressed the witness accounts of small-stature bodies and identified them as displaced memories of crash-test dummies dropped during 1953–1959 high-altitude testing programs. The 1995 GAO report acknowledged that most Roswell Army Air Field administrative records for spring 1947 had been destroyed at some point during the 1950s through unspecified routine procedure. No federal investigation has been formally reopened since 1997. Subsequent UAP-related federal activity (AATIP, the 2021 ODNI report, the 2023 Grusch hearings, the Schumer-Rounds UAP Disclosure Act) has not formally addressed the 1947 case.

Where it is now

Roswell has become a permanent feature of American cultural geography. The International UFO Museum and Research Center on North Main Street in downtown Roswell, co-founded by Walter Haut in 1991, receives approximately 200,000 visitors per year. The annual Roswell UFO Festival, held each July around the anniversary, draws additional tens of thousands. The Foster Ranch site itself remains private property and is not publicly accessible. Mac Brazel's gravesite is in the Capitan Cemetery in Lincoln County. Walter Haut's gravesite is in Roswell.

The case's role in contemporary UAP discourse has shifted. The 2017 New York Times reporting on the Pentagon's Advanced Aerospace Threat Identification Program, the 2019 Navy public acknowledgments of the Tic Tac and Gimbal incidents, the 2021 ODNI Preliminary Assessment, the 2023 House Oversight hearings featuring former intelligence officer David Grusch's allegations of an undisclosed crashed-craft retrieval program, and the 2023–2024 UAP Disclosure Act provisions introduced by Senators Charles Schumer and Mike Rounds have collectively shifted the official posture from denial to a constrained acknowledgment that anomalous phenomena require institutional study. None of these subsequent disclosures have formally revisited 1947. Several have referenced it implicitly: Grusch's testimony spoke of a long-running US program of crashed-craft retrieval and reverse engineering whose alleged origin point is, for most independent researchers reading the testimony, the case at hand.

Whether the contemporary disclosure track will, before it concludes, formally revisit the events at the Foster Ranch in early July 1947 is the open question. President Trump's December 2024 interview comments — "I do know interesting things about Roswell" — were not elaborated on. As of 2026, the case stands where it has stood since 1997: with one explanation on the federal record, multiple independent witness accounts that the official explanation does not fully account for, and a steady accumulation of adjacent disclosures that have begun to make the original record's silences more visible.

Frequently asked questions

What was the Roswell incident?

The Roswell incident refers to the July 1947 recovery, by personnel of the Roswell Army Air Field's 509th Bomb Group, of unidentified debris from the J.B. Foster Ranch approximately 75 miles northwest of Roswell, New Mexico. On July 8, 1947, RAAF issued a press release stating the base had "gained possession of a flying disc." The Roswell Daily Record carried it as the front-page story under the headline "RAAF Captures Flying Saucer On Ranch in Roswell Region." The following day, the Army's 8th Air Force, headquartered at Fort Worth, retracted the announcement and stated the debris was from a weather balloon. The reversal, the photographs of the substituted material, and the subsequent decades of witness reversals are what generated the case as it now exists.

Who found the Roswell debris?

William W. "Mac" Brazel, a rancher and foreman of the J.B. Foster Ranch, discovered scattered debris in mid-June 1947 (his later recall placed the discovery on or near June 14). The debris consisted of metallic foil-like sheets that reportedly would not tear or burn, beam-like material with unusual markings, and rubber-like fragments. Brazel did not initially report the find. Following the widely-publicized June 24, 1947 sighting by pilot Kenneth Arnold over Mount Rainier — the event that introduced the term "flying saucer" to the American public — Brazel traveled to Roswell on July 7, 1947 and reported the debris to Sheriff George Wilcox, who contacted the Roswell Army Air Field.

What was Project Mogul?

Project Mogul was a top-secret United States Army Air Forces program (1947–1949) operated by the New York University Constant Level Balloon Group under physicist Charles B. Moore (with senior involvement from James A. Van Allen) that sent long arrays of high-altitude balloons carrying acoustic sensors into the upper stratosphere. The objective was to detect Soviet atomic-bomb tests by listening for low-frequency pressure waves in the sound channel of the upper atmosphere. The 1994 USAF report by Col. Richard Weaver identified Mogul Flight #4, launched June 4, 1947 from Alamogordo, New Mexico, as the most likely source of the debris recovered from the Foster Ranch. Charles B. Moore participated in the 1990s investigation and supported the Mogul identification.

What did Maj. Jesse Marcel say about Roswell?

Maj. Jesse A. Marcel Sr. was the intelligence officer of the 509th Bomb Group at the Roswell Army Air Field in July 1947. He personally drove to the Foster Ranch with Mac Brazel and Capt. Sheridan Cavitt, collected debris, and flew it from Roswell to Fort Worth, where Brig. Gen. Roger Ramey held the press conference declaring the material a weather balloon. The famous photographs of the recovery show Marcel posing with the balloon material at Fort Worth. In 1978–1979 interviews with nuclear physicist Stanton Friedman, Marcel publicly stated for the first time that the weather-balloon story had been false, that what he had collected was "not anything from this Earth," and that the material at Fort Worth had been substituted before the press conference. Marcel's 1978 reversal is the event that revived the Roswell case after 30 years of dormancy.

What was the alien autopsy film?

In 1995, British music producer Ray Santilli released approximately 17 minutes of black-and-white 16mm footage purportedly showing an autopsy on a humanoid creature recovered from a 1947 New Mexico crash site. The footage was first broadcast in the United States on August 28, 1995 in the Fox television special "Alien Autopsy: Fact or Fiction?", hosted by Star Trek actor Jonathan Frakes. The footage generated international coverage. In 2006, Santilli publicly admitted that the footage as released was a "reconstruction" produced with the assistance of sculptor Spyros Melaris. Santilli has continued to claim that the reconstruction was based on genuine 1947 footage that had degraded; no original footage has been produced.

What did the 1994 Air Force report conclude?

The September 1994 USAF report, prepared by Col. Richard Weaver of the Air Force Office of Special Investigations and titled "The Roswell Report: Fact vs. Fiction in the New Mexico Desert," concluded that the debris recovered from the Foster Ranch in July 1947 was the remnants of a Project Mogul balloon array — most probably the June 4 launch identified internally as Flight #4. The report acknowledged that the project's classification at the time had prevented base-level personnel, including Maj. Marcel, from being told what they had recovered. A follow-up June 1997 report, "The Roswell Report: Case Closed," addressed the alleged "alien body" witness accounts and concluded these were memories of crash-test dummies dropped during 1953–1959 high-altitude testing.

Who was Walter Haut?

Lt. Walter Haut was the public information officer of the 509th Bomb Group at Roswell Army Air Field in July 1947. He drafted and released the July 8, 1947 press release announcing that the base had "gained possession of a flying disc." The release was approved by the base commander, Col. William "Butch" Blanchard. Haut remained in Roswell for the rest of his life and in 1991 co-founded the International UFO Museum and Research Center in Roswell. In 2002, Haut signed a sworn affidavit, sealed until after his death, in which he stated that he had personally seen a recovered craft and small bodies at the base. Haut died in 2005; the affidavit was released in 2007.

What is the significance of the 509th Bomb Group?

In July 1947, the 509th Bomb Group at Roswell Army Air Field was the only nuclear-weapons-armed bomber group in the United States military. It was the same unit that had delivered the atomic bombs to Hiroshima and Nagasaki in August 1945. Independent researchers have argued the unit's status — the highest concentration of military secrecy and operational security in the country at that moment — is incompatible with the official explanation, which would require the unit's intelligence officer to have misidentified an ordinary weather-balloon array. Defenders of the official explanation argue the inverse: precisely because Mogul itself was classified above the level of the 509th's local intelligence personnel, Maj. Marcel could plausibly not have been briefed.

Has the US government acknowledged Roswell?

The official US government position remains that the July 1947 debris was Project Mogul material and that subsequent "alien body" accounts were displaced memories of 1950s crash-test dummies. Congressman Steven Schiff (R-NM) requested a formal General Accounting Office investigation in 1993; the GAO report was issued July 1995. The 1994 and 1997 USAF reports remain the formal federal positions. Beyond the Roswell case specifically, the broader US government posture toward unidentified anomalous phenomena has shifted substantially since 2017 — Pentagon AATIP disclosures, the 2021 ODNI UAP preliminary assessment, the 2023 House Oversight hearings featuring David Grusch, and the Schumer-Rounds UAP Disclosure Act provisions of 2023–2024. None of these subsequent developments have formally revisited the 1947 case.

What happened in Roswell after the 1947 incident?

The case was effectively dormant from late July 1947 until 1978, when Stanton Friedman's interviews with Maj. Jesse Marcel revived public attention. The 1980 book "The Roswell Incident" by William L. Moore and Charles Berlitz consolidated the renewed interest. The International UFO Museum and Research Center opened in Roswell in 1991, co-founded by Walter Haut. The annual Roswell UFO Festival, launched in 1996 (the 50th anniversary year fell in 1997), has become a sustained tourism economy for the city. The case continues to function as the foundational reference point for modern UFOlogy and was directly cited in 2024 by President Donald Trump in interviews with Tucker Carlson and Donald Trump Jr.
