Every indexed UAP case documented in North America, drawn from publicly available official government records — NARA RG 615, AARO, NASA, FBI, and DoD PURSUE program releases.
In July 1947, Roswell Army Air Field announced the recovery of a 'flying disc' near Roswell, New Mexico, then retracted the statement and identified the debris as a balloon. It became the most widely cited UFO case in U.S. history.
Federal agents witnessed orange orbs described as resembling 'the Eye of Sauron without a pupil', emitting smaller red orbs in groups of 2–4. Rated 'among the most compelling cases in AARO's holdings.'
An ellipsoid bronze metallic object, 130–195 feet in length, materialized from a bright light and disappeared instantaneously. Rated among the most extraordinary events in the public archive record set.
FBI Photo B20: an infrared still of an unidentified craft hovering at under 1,000 ft for 45 minutes. Object defied wind conditions and maintained perfect stationary position with no discernible propulsion.
A massive V-shaped formation of lights traversed Arizona from north to south on March 13, 1997, witnessed by an estimated 10,000 people including the sitting governor. FAA radar records and military communications included in the 2026 archive release remain unexplained for the formation event.
A metallic disc-shaped object was observed hovering silently over Gate C17 at O'Hare International Airport by over a dozen United Airlines employees and flight crew. The FAA initially denied radar contact; a Freedom of Information Act release revealed internal FAA discussion of the event. The object punched a clear circular hole through the overcast cloud layer upon departure.
An F/A-18 Super Hornet ATFLIR pod captured a disc-shaped object visibly rotating against the direction of wind at 25,000 feet. The object moved into the prevailing wind and appeared to rotate continuously with no visible means of propulsion. DoD officially released the FLIR footage in 2020; AARO lists it as unresolved.
FLIR footage declassified by DoD captures a small, fast-moving object skimming approximately 25 feet above the Atlantic Ocean surface. Speed calculations from the FLIR data indicate the object was moving at a speed inconsistent with any known drone or projectile at that altitude. AARO classifies the GoFast as unresolved.
Multiple unidentified objects were tracked on radar at Washington National Airport and Andrews AFB on two separate weekends in July 1952. USAF interceptors were scrambled twice; objects vanished when jets arrived and returned when jets departed. This prompted the largest Air Force press conference since World War II and remains one of the best-documented mass radar UAP events in U.S. history.
JAL Boeing 747 Captain Kenjyu Terauchi reported two unidentified objects flanking his aircraft for 50 minutes over Alaska, followed by a massive object he described as 'twice the size of an aircraft carrier' which appeared ahead of the plane. FAA Anchorage center and Elmendorf AFB radar confirmed returns. The FAA opened a formal investigation.
Over 40 witnesses in the Stephenville, Texas area reported a massive object approximately one mile wide with white strobing lights flying low and silently in January 2008. F-16s pursued the object. FAA radar data obtained by MUFON through FOIA showed the object tracking toward the Crawford, Texas airspace — the location of President Bush's ranch — before military jets pursued.
USAF Lieutenant George Gorman pursued a fast-moving luminous orb for 27 minutes over Fargo in his F-51 Mustang. The object executed head-on passes, outran the F-51, and climbed vertically faster than the aircraft could follow. Independently confirmed by control tower operators and two CAA controllers. Project Sign investigated and listed it as one of the 'best unexplained' cases.
A V-shaped formation of soft blue-green lights traveled silently over Lubbock, Texas on multiple occasions in late 1951, witnessed initially by four Texas Tech professors and subsequently photographed by 18-year-old Carl Hart Jr. The photographs were analyzed by Project Blue Book and the Air Force never produced a definitive explanation. Blue Book's final report lists it as 'unknown.'
A USAF RB-47 electronic countermeasures aircraft tracked an unknown object visually, on airborne radar, and via its electronic intelligence equipment simultaneously for over 90 minutes across multiple states. The object appeared, disappeared, and reappeared on three different sensor systems independently. Project Blue Book's Scientific Consultant, Dr. James McDonald, called it 'one of the most puzzling in the whole Blue Book collection.'
Socorro police officer Lonnie Zamora observed a white oval craft with red insignia resting on legs in an arroyo, attended by two figures in white. He observed the craft take off with a roaring flame, become silent after 20 feet, and depart at high speed. Physical evidence — burned vegetation, soil compression, metal scrapings — was immediately confirmed by State Police and Army investigators. Project Blue Book listed this as 'unknown.'
Over the course of two hours on November 2, 1957, nine independent witnesses in and around Levelland, Texas reported their vehicles' engines dying and headlights extinguishing when a large, glowing egg-shaped object appeared near or over their vehicles. Engines and electrical systems restarted immediately when the object departed. Six separate highway incidents in different locations within a 10-mile radius all occurred within the same two-hour window.
In March 1967, a red-orange glowing orb was observed hovering over Launch Control Facility Echo at Malmstrom AFB. Within minutes, all ten Minuteman ICBMs at Echo went into 'No-Go' status — the missiles were inoperable for nuclear launch. A similar event was reported separately at Oscar Flight the same morning. The event has never received an unclassified technical explanation.
Multiple witnesses observed 4 amber-lit objects fly in formation over Shag Harbour, Nova Scotia, before one entered the ocean. RCMP officers confirmed the sighting. Canadian military divers searched but found no wreckage. Canadian government opened an official investigation, classifying it as 'unknown' — making it one of the few government-acknowledged transmedium UAP events in the historical record. U.S. SOSUS and naval records are in the 2026 archive release.
Newly declassified Armed Forces Special Weapons Program records document 209 separate UAP sightings at Sandia Base, New Mexico — the nation's primary nuclear weapons facility — between 1948 and 1950. Witnesses, primarily military personnel, described orbs that performed high-speed maneuvers and, in several cases, appeared to explode. The proximity to classified nuclear infrastructure was assessed as a national security concern. The files are part of the May 2026 Pentagon archive release.
A senior U.S. intelligence officer flying aboard a military helicopter over a western U.S. military test range in 2025 encountered what they described as 'countless orange orbs swarming in all directions.' The objects were oval-shaped with orange and white centres. At one point a group of the orbs assembled into a triangular formation before vanishing. The encounter lasted over an hour. The witness account is included in the May 2026 Pentagon archive release.
On February 12, 2023, a U.S. Air Force F-16 shot down an unidentified object over Lake Huron, Michigan, on orders from the White House. The incident was part of a four-day period in which the U.S. military shot down four objects over North American airspace following the Chinese balloon shootdown. A classified video recorded by the fighter jet during the intercept is included in the May 2026 Pentagon archive release — the first time cockpit footage from this engagement has been made public.
US Army anti-aircraft batteries fired 1,400 rounds at an unidentified object hovering over Los Angeles. The object was illuminated by searchlights for over an hour and did not fall. The Secretary of the Navy attributed it to 'war nerves'; the Secretary of War stated a physical object was present. The official explanation remains contradicted by its own chain of command.
USAF F-89C Scorpion interceptor with two crew was vectored toward an unidentified radar return over Lake Superior. Ground radar operators watched the F-89's blip merge with the unknown target's blip — then only one blip remained, which flew north into Canada and disappeared. The aircraft, crew, and wreckage were never found.
Farmer Paul Trent photographed a metallic disc-shaped object near his farm in McMinnville, Oregon. The two photographs became the most analyzed UAP images in history — Project Blue Book, the Condon Committee, and independent photogrammetric analysts all concluded the images were genuine and not a hoax.
Approximately 500 Farmington, New Mexico residents simultaneously observed a massive fleet of hundreds of disc-shaped objects flying in formation overhead for 30 minutes. Three local newspaper reporters independently witnessed the event and filed reports. The objects were documented at high altitude traveling at high speed in formation, with individual objects breaking formation and rejoining. Project Blue Book declined to investigate.
Signal Corps radar operators at Fort Monmouth tracked an unidentified target at 93,000 feet moving at estimated 700 mph with instant course reversals. A T-33 jet pilot simultaneously observed a disc from his cockpit. The incident alarmed General Charles Cabell, Air Force Director of Intelligence, who personally travelled to Wright-Patterson to demand Project Grudge be upgraded — directly leading to the formation of Project Blue Book.
An F-94C Starfire interceptor was scrambled from Griffiss AFB to intercept an unidentified target. The crew reported the cockpit filled with intense heat during the intercept, forcing both men to eject. The unmanned aircraft crashed in Walesville, New York, killing a family of three in their car and a fourth person on the ground. Project Blue Book classified the file SECRET.
Edwards AFB control tower controllers and multiple F-104 Starfighter test pilots observed a metallic disc maneuvering over the base at high altitude. The object was tracked visually by tower personnel and by pilots in flight. Project Blue Book investigated and logged the case as 'unidentified.' The encounter is notable for occurring at the USAF's primary aircraft test facility with multiple trained military aviators as witnesses.
An extended series of close-encounter UAP events affected the population of Colares Island in northern Brazil over several months. Objects fired concentrated beams of light at residents, causing documented physical injuries. The Brazilian Air Force conducted secret Operation Prato, deploying personnel to observe and photograph the objects. The classified report, declassified in 2004, documented hundreds of incidents and included photographs of the craft.
Private pilot Kenneth Arnold reported nine crescent-shaped objects flying in formation near Mount Rainier at an estimated 1,700 mph — far exceeding any known aircraft of the era. His account coined the term 'flying saucer' and triggered the first formal FBI and Army Air Force investigation.
Harbor patrolman Harold Dahl reported six donut-shaped objects over Puget Sound, one of which ejected metallic and slag-like debris that damaged his boat and injured a crew member. FBI files document the subsequent investigation and the mysterious deaths of two Army Air Force officers carrying recovered material.
USAF Captain Thomas Mantell died when his F-51 Mustang disintegrated at 30,000 ft while pursuing a large, metallic, stationary object over Fort Knox. Godman Field tower personnel and multiple pilots observed the object. Project Sign classified the incident SECRET. No official explanation has been accepted.
Two experienced Eastern Airlines captains reported a cigar-shaped, double-decked object with a blazing exhaust that passed within 700 feet of their DC-3 at 700 mph over Montgomery, Alabama. Project Sign analysts concluded it was the 'most credible' UAP report of 1948 and drafted a classified estimate attributing it to extraterrestrial origin.
A series of brilliant green fireballs overflew the Los Alamos and Sandia nuclear facilities repeatedly throughout 1948–1949. The Air Force, FBI, and nuclear scientists concluded the objects did not match meteor or ball lightning behavior. Dr. Lincoln La Paz formally assessed them as artificial in a classified report to the FBI.
Nick Mariana captured approximately 16 seconds of 16mm color footage showing two bright disc-shaped objects flying in formation over Great Falls, Montana. USAF Project Blue Book analyzed the film and initially attributed the objects to F-94 jets; subsequent independent analysis found the objects' luminosity and flight path inconsistent with that explanation.
Navy CPO Delbert Newhouse filmed approximately four minutes of 16mm footage showing a formation of bright, disc-shaped objects maneuvering over Tremonton, Utah. The Navy's Photo Interpretation Laboratory spent 1,000 man-hours analyzing the film and concluded the objects were not aircraft, birds, or balloons — and were 'self-luminous.'
Two Exeter police officers and a civilian witness observed a massive, low-flying object with a ring of red pulsing lights hovering at treetop level and silently maneuvering for approximately 45 minutes. Project Blue Book initially classified the case as 'insufficient data,' then revised to 'unidentified' after the officers filed formal objections.
Two Portage County Sheriff's deputies pursued a luminous disc-shaped object for 85 miles across Ohio into Pennsylvania, joined mid-pursuit by officers from multiple jurisdictions. Project Blue Book attributed the object to Venus — an explanation the officers publicly disputed, triggering congressional scrutiny of the Blue Book program.
A B-52H crew and ground radar simultaneously tracked an unidentified object over Minot AFB's nuclear missile field. The object descended to 200 feet, disrupted radio communications, and was observed by base security near missile launch facilities. Project Blue Book closed the case as 'insufficient data' — later declassified Blue Book files show the radar returns were confirmed as real targets.
An Army Reserve UH-1 helicopter crew of four had a near-collision with a large grey metallic object over Mansfield, Ohio. The object stopped the helicopter's controlled descent and the aircraft inexplicably climbed 2,000 feet with no crew input. The incident is regarded as one of the most credible military UAP cases in the official record due to the four-person trained military crew and corroborating ground witnesses.
A large acorn-shaped metallic object with a raised band of unknown symbols around its base crashed into woods near Kecksburg, Pennsylvania. The Army cordoned off the area within hours and reportedly recovered a large object on a flatbed truck. NASA reopened the case in 2003 following a lawsuit and could not produce the original investigation file.
Three civilians suffered documented acute radiation injuries after a close encounter with a large diamond-shaped, flame-emitting craft escorted by 23 military Chinook helicopters on a Texas highway. The witnesses sued the U.S. government for damages; the case was dismissed because the government denied ownership of either the craft or the Chinook escort.
An unidentified helicopter-like object repeatedly overflew the nuclear weapons storage area at Loring AFB over several nights in October 1975. SAC headquarters issued an urgent classified message acknowledging the intrusions. Similar incidents occurred simultaneously at Wurtsmith, Malmstrom, Minot, and Canadian Forces Base Falconbridge — suggesting a coordinated operation against North American nuclear sites.
A multi-year wave of sightings of a massive V-shaped or boomerang-shaped craft with white lights produced over 7,000 documented witness reports across New York and Connecticut. FAA radar at Stewart Airport confirmed unidentified targets. The object was observed hovering silently over the Indian Point Nuclear Power Plant.
U.S. Customs and Border Protection thermal infrared footage recorded a pinkish orb flying at ~80 mph at low altitude near Aguadilla Airport before entering the Atlantic Ocean without a splash, transiting underwater at estimated 90+ mph, and re-emerging from the ocean. AARO independently analyzed the footage and confirmed no conventional explanation.
Two Pan American Airways pilots observed eight large glowing discs in tight formation performing sharp directional reversals at high speed over Chesapeake Bay. USAF Project Blue Book investigators and the Civil Aeronautics Administration conducted a formal investigation. The case was never explained and is listed as an official 'Unknown' in Project Blue Book files.
Seven civilians including a National Guard member observed a pulsing craft and tall luminous entity on a hillside in Flatwoods, West Virginia. Multiple witnesses reported physical symptoms including irritated eyes and throat consistent with chemical exposure. FBI and USAF investigators formally documented the case; local sheriff Robert Carr filed an official report.
Shipyard workers Charles Hickson and Calvin Parker reported being taken aboard an oval craft along the Pascagoula River. Jackson County Sheriff Fred Diamond secretly recorded the pair when left alone in an interrogation room; they continued their accounts believing they were unobserved. USAF Project Blue Book had closed in 1969 but Navy Intelligence reviewed the case. Medical examinations found no signs of deception.
Two engineers observed a large egg-shaped object hovering silently over the Loch Raven Dam bridge. Their vehicle engine and lights failed during the approach. Upon the object's departure in a flash of white light, both men experienced sunburn-like symptoms and were examined by physicians. The USAF 438th Air Intelligence Service Squadron formally investigated and the case was classified 'Unknown' in Project Blue Book.
Multiple UAPs were observed over Kirtland Air Force Base's nuclear weapons storage area in August–October 1980. Security police and Sandia National Laboratories personnel filed official reports. The Kirtland incident was the subject of a classified USAF intelligence report later released to researcher Lawrence Fawcett via FOIA. The objects directly overflew the Manzano Weapons Storage Area housing nuclear warheads.
A series of photographs taken from the USS Trepang (SSN-674) nuclear submarine while operating in the Arctic Ocean show unidentified disc-shaped and cigar-shaped objects near the sea surface and ice. The photographs were classified SECRET. Declassified versions were released by researcher John Greenewald via FOIA and authenticated by naval historians. They show objects displaying transmedium behavior — transitioning between air and water.
Beginning in November 1987, a series of UAP incidents occurred over Gulf Breeze, Florida. Multiple photographs were taken by local contractor Ed Walters and later by ~130 other independent witnesses. FAA radar confirmed unidentified targets over the Gulf of Mexico. Military pilots reported visual contacts. MUFON (Mutual UFO Network) investigators, a medical doctor, and a USAF physician analyzed the physical effects reported by primary witness Walters.
The US Office of the Director of National Intelligence released a landmark Preliminary Assessment on UAP to Congress in June 2021. The classified report covered 144 incidents reported by US government sources, primarily military aviators. Of 144 reports, 143 could not be explained. Eighteen incidents showed 'unusual movement patterns or flight characteristics' including hypersonic speeds without propulsion signatures, no visible propulsion, and transmedium travel.
The USS Kearsarge (LHD-3) amphibious assault ship and USS The Sullivans (DDG-68) destroyer tracked unidentified spherical craft operating near and entering the Atlantic Ocean in July 2019. Multiple sensor systems across both ships confirmed the objects. The incident was reported to the UAP Task Force and is referenced in AARO's case database as a confirmed transmedium event. Crew members filed official Defense Department UAP reports.
The crew of American Airlines Flight 2292 reported a long cylindrical object passing over their Boeing 737 at altitude FL370 at speed. The FAA radio transmission was recorded and obtained by aviation journalist Steve Douglass. American Airlines confirmed the report was genuine. The FBI contacted American Airlines for additional information. The crew described the object as a 'long cylindrical object that almost looked like a cruise missile moving very fast.'
The All-domain Anomaly Resolution Office (AARO) delivered Volume I of its Historical Record Report to Congress on March 8, 2024. The report reviewed US government UAP investigations from 1945 to 2023, interviewed 30 witnesses, reviewed hundreds of classified programs, and found no evidence of non-human intelligence or hidden US reverse-engineering programs. It confirmed a documented pattern of UAP reports near nuclear and advanced weapons facilities dating to 1945.
Two Kentucky families reported a multi-hour siege by several small luminous humanoid entities at a rural farmhouse. The witnesses, finding they could not be harmed by gunfire, barricaded themselves and eventually fled. Kentucky State Police officers, Christian County Sheriff's deputies, and US Army MP personnel from nearby Fort Campbell responded. Officials documented a pattern of bullet holes in the house and found strange metallic-looking rings around the well.
Over two nights in Michigan, approximately 100 witnesses including county sheriffs' deputies and a civil defense director observed disc-shaped craft at low altitude. USAF Project Blue Book sent Dr. J. Allen Hynek to investigate. Hynek's official explanation — 'swamp gas' — caused national ridicule and congressional outrage, directly triggering the Condon Committee investigation and Congressman Gerald Ford's formal congressional inquiry.
Multiple tracking cameras and radar at the classified Nellis Test Range in Nevada recorded a white disc-shaped object performing extreme maneuvers over a period of approximately 30 minutes. The footage was obtained via a source and broadcast by a television network in 1995. USAF Nellis Range control confirmed the incident occurred and that the object was unidentified. The footage shows the object abruptly changing direction and speed in ways inconsistent with any known aircraft.
US Army MPs at Fort Dix reported encounters with humanoid entities near the base perimeter following reports of low-flying craft. A military policeman shot and wounded one entity, which fled to the McGuire AFB flight line and was found dead. The body was transported by US Air Force personnel. The classified incident report was later leaked to researcher Len Stringfield and has been cited in multiple FOIA requests to the DoD.
Dr. Clyde Tombaugh, discoverer of the dwarf planet Pluto and a leading observational astronomer working at White Sands Missile Range, formally reported observing a fast-moving rectangular formation of lights on August 20, 1949. Tombaugh also made additional observations from his home in Las Cruces. His formal reports to the USAF and to Project Blue Book are preserved in government archives. Tombaugh stated the objects moved with 'precision control.'
A Mexican Air Force C-26A maritime patrol aircraft crew filmed 11 orb-shaped objects on infrared tracking over Campeche State. The crew's radar detected the objects but they were invisible to the naked eye. The footage was released officially by Mexico's Secretary of National Defense (SEDENA) with a press conference, making Mexico one of the only countries to officially release military UAP footage with government endorsement.
Prior to the famous November 2004 Nimitz Tic-Tac encounter, pilots from VFA-41 'Black Aces' flying exercises off NAS Fallon reported similar encounters with unknown aerial objects during pre-deployment workups. These pre-Nimitz reports established a pattern of contact that the operational commanders were aware of when the encounters peaked in November 2004. The NAS Fallon reports are referenced in AARO case records as precursor events to the Nimitz incident.
Transport Canada maintains an official UAP (referred to in Canadian aviation as 'UFO') reporting protocol for civil and military aviation personnel. Canada's National Research Council was among the earliest official bodies to formally investigate UAP reports (1950 onward). Canadian Department of National Defence records include hundreds of formally investigated cases. The Transport Canada UAP protocol makes Canada one of the only countries with an institutionalized civilian aviation reporting framework for UAP.
Peruvian Air Force Commander (then Lieutenant) Oscar Santa María Huerta scrambled a Sukhoi-22 fighter to intercept a bright spherical object near La Joya Air Base. He fired 64 rounds at the object at close range — the rounds appeared to pass through it or had no effect. The object then climbed to extreme altitude, outrunning the aircraft. Santa María Huerta later testified before the United Nations and the US Congress, and is one of the most credentialed military pilot witnesses in the global UAP record.
On February 10, 2023, a USAF F-22 Raptor fired an AIM-9X missile and shot down a cylindrical object near Deadhorse, Alaska at approximately 40,000 feet. The object had been tracked by NORAD for approximately 24 hours. President Biden publicly ordered the shootdown. Recovery teams were deployed but could not locate substantial debris. The object's origin and purpose were never publicly identified — the DoD did not attribute it to any nation or program.
A USAF Intelligence officer observed a disc-shaped object through binoculars in full daylight over the Rogue River, Oregon. The officer filed a formal Project Blue Book report. His training in aircraft identification and position as an intelligence officer made the report one of the most credentialed in the early Blue Book record. The object was estimated at 50 feet in diameter, highly reflective, and departed at extreme speed.
US Air Force and Navy radar operators at facilities in the Mojave Desert region tracked an unidentified orb-shaped object operating at extreme altitude over the restricted test range complex. Edwards AFB and China Lake personnel both tracked the object. A USAF test aircraft was diverted to investigate; the pilot could not close on the object. The incident was reported to AARO and is referenced in its 2023 operational case files.
Luminous unidentified craft were observed over the Minuteman ICBM missile fields of F.E. Warren AFB in Wyoming across multiple nights in late 1976. SAC security police filed formal reports. Launch control officers reported anomalous indications in missile launch enable status during UAP proximity. The classified reports were later released under FOIA and are preserved in the National Security Archive.
A massive triangular craft was observed over Cabo Rojo, Puerto Rico, by hundreds of witnesses including police officers, US Customs agents, and FAA tower personnel. The craft was tracked on FAA radar. Multiple witnesses reported the craft descending into the ocean. The incident was formally investigated by MUFON and referenced in FAA records. Puerto Rico police dispatched officers who observed the craft at close range.
A disc-shaped object observed over South Haven, Michigan was simultaneously tracked by USAF radar and visually confirmed by law enforcement from multiple agencies. Project Blue Book classified the case as 'Unknown.' The radar returns showed the object performing maneuvers far beyond any known 1967 aircraft. The case is notable for the simultaneous police, sheriff, and USAF radar corroboration.
Japan Air Lines Flight 1628, a Boeing 747 cargo flight from Paris to Tokyo, encountered two objects and then a massive third object — estimated at the size of two aircraft carriers — over Alaska for approximately 50 minutes. FAA Anchorage Center radar confirmed an unidentified return. USAF Elmendorf AFB radar also briefly confirmed contact. The FAA investigated and Captain Terauchi gave a formal statement. The investigation is one of the most thoroughly documented FAA radar-visual cases.
A luminous object maneuvering over Colusa County, California was tracked on FAA radar for approximately 40 minutes and observed by law enforcement officers from multiple agencies. The object paced law enforcement vehicles, descended to near-ground level, and departed at high speed. FAA radar records were preserved and reviewed by NICAP investigators. The case is classified as an official FAA 'Unknown' in its records.
California Governor Ronald Reagan and his pilot Bill Paynter observed a bright white light that paced their Cessna Citation for several minutes and then accelerated to extreme speed and disappeared. Paynter filed a written report. Reagan subsequently told the story publicly on multiple occasions, including to Norman Miller of the Wall Street Journal in 1974. Reagan later referenced the experience when speaking to the United Nations about the possibility of an extraterrestrial threat.
In September 1994, the US Air Force released an official investigation report on the Roswell incident, concluding the recovered debris was from Project Mogul — a classified balloon array. The report was a formal DoD document addressing the most famous UAP case in history. The 1997 follow-up report addressed 'alien body' accounts by attributing them to test dummies. Both reports remain the official US government position on Roswell and are primary source documents in the NARA archive.
On December 16, 2017, the New York Times published a front-page story revealing the existence of the Advanced Aerospace Threat Identification Program (AATIP), a classified $22 million Pentagon UAP investigation program that ran 2007–2012. The story included the first officially released DoD UAP videos (Nimitz and Gimbal) and an interview with program director Luis Elizondo, who resigned citing internal obstruction. The disclosure marked the beginning of the modern era of US government UAP transparency.
In April 2019, the US Navy announced a new formal policy requiring pilots to report UAP encounters through official channels — the first such formal acknowledgment in decades. In September 2019, the Navy confirmed the three widely circulated UAP videos (Nimitz, Gimbal, GoFast) were genuine US Navy footage. In April 2020, the Pentagon officially released the three videos. These sequential official acts established the modern US government acknowledgment framework.
On July 26, 2023, the US House of Representatives held a landmark open hearing in which former intelligence official David Grusch testified under oath that the US government had a secret program to retrieve and reverse-engineer non-human craft. Former Navy pilots Ryan Graves and David Fravor testified about UAP encounters. Grusch subsequently filed a formal whistleblower complaint with the DoD Inspector General. The hearing was the most significant congressional UAP transparency event in 50 years.
The Fiscal Year 2024 National Defense Authorization Act included provisions establishing a UAP Records Review Board modeled on the JFK Assassination Records Act, requiring government contractors to report UAP-related materials, and expanding AARO's investigative authority. The legislation was the most significant Congressional UAP action since 1969 and mandated unprecedented access to classified UAP program records.
Project Sign was the US Air Force's first official UAP investigation program, established January 22, 1948. Its analysts produced a classified 'Estimate of the Situation' that concluded the best UAP evidence supported an extraterrestrial hypothesis. Air Force Chief of Staff General Hoyt Vandenberg rejected the estimate and ordered it destroyed. The original report no longer exists; surviving copies were found in 1969.
Project Blue Book, the US Air Force's official UAP investigation program running 1952–1969, was closed on December 17, 1969, following the Condon Committee's assessment that UAP investigation offered no scientific value. Of 12,618 cases investigated, 701 were officially classified as 'Unknown' — never explained. The case files were declassified and transferred to NARA, where they form the primary public UAP archive. Captain Edward Ruppelt's memoir documented internal conflicts over objectivity.
In October 1886, nine members of a family in Maracaibo, Venezuela reported being awakened by a bright light and a humming sound from a luminous craft. All nine family members experienced physical symptoms: swelling, black blotches on skin, hair loss, and vomiting lasting days. The case was formally reported to the Maracaibo Scientific Society and documented by physician Dr. Beauperthuy. The report was published in the journal Science in January 1887 — the earliest documented UAP physical effects case in a peer-reviewed publication.
The Cape Girardeau incident is one of the alleged pre-Roswell crash recovery cases. Reverend William Huffman reportedly witnessed a crashed craft and non-human occupants and was asked to pray over the bodies. His family members testified to his account decades later. FBI records referencing 'three discs recovered' in the Midwest were later cited in connection with 1940s crash recovery allegations. The case is unverified but has been investigated by multiple researchers using FOIA requests.
Patrolman Lonnie Zamora observed a white egg-shaped craft land in the Socorro desert, observed two small figures near it, and watched it depart vertically. The physical evidence — four circular landing impressions, burned brush at four locations, and a rock with blue flame residue — was documented by USAF Project Blue Book investigators. Dr. J. Allen Hynek considered it his single best case. The landing impressions were formally measured and preserved. Classified CIA and USAF documents reference this case specifically.
The Mexican Civil Protection Agency's permanent monitoring webcam on Popocatépetl captured video footage of a large cigar-shaped or cylindrical object flying into the active volcano's crater. The footage was authenticated by the Mexican government agency. The object appeared to enter the volcanic vent. The webcam is a permanent government monitoring installation; the footage was released through official channels.
The Great Airship Wave of 1896–1897 involved hundreds of reports across the United States of large cigar-shaped airships — years before controlled powered flight. The Aurora, Texas incident on April 17, 1897 reported a crash of an unidentified craft on a local judge's property and an alleged non-human occupant buried in the Aurora cemetery. Texas state historical records document the incident; the Dallas Morning News published the original account. Modern ground-penetrating radar surveys of the grave site found anomalous metallic material.
Canadian Forces Base Falconbridge experienced UAP intrusions in November 1975, simultaneous with the documented wave of US nuclear base incursions at Loring, Wurtsmith, Malmstrom, Minot, and Warren AFBs. NORAD radar confirmed contacts over the Canadian base. The incidents were formally documented in classified SAC messages that were later released under FOIA. The simultaneous nature of the Canadian and US incidents suggested a coordinated pattern across North American nuclear infrastructure.
The November 2004 Nimitz events — involving 2 weeks of Princeton radar tracks and visual intercepts by multiple F/A-18 pilots — produced the classified 'FLIR1' (Tic-Tac) video. Commander Fravor's visual encounter remains the most detailed public official account of a close-range UAP intercept by a trained military pilot. The official DoD FLIR video was declassified and released in 2020. This incident is the anchor event of the modern era of US government UAP acknowledgment.
On February 12, 2023, a USAF F-16 Fighting Falcon shot down an unidentified object over Lake Huron, Michigan at approximately 20,000 feet. The object had been tracked by NORAD. President Biden ordered the shootdown. Recovery operations in Lake Huron proved challenging due to the depth of the lake. The DoD did not publicly attribute the object to any nation or program. This was the fourth object shot down in 9 days.
Beginning in November 2024, a sustained wave of unidentified aerial objects over New Jersey prompted responses from the FAA, DHS, FBI, and US military. President Biden was briefed. Senator Chuck Schumer publicly demanded answers. Some objects were tracked by FAA radar without corresponding flight plans. The FBI opened an investigation. AARO received hundreds of reports. The DoD ultimately stated most objects were likely drones but acknowledged some could not be identified.
The USS Theodore Roosevelt Carrier Strike Group documented sustained UAP encounters across its 2014–2015 deployment. F/A-18 crews from VFA-11 reported near-daily UAP encounters. Two incidents — GIMBAL (an object rotating against the wind) and GOFAST (a fast-moving low-altitude object) — produced the official DoD infrared videos released in 2020. Pilot Ryan Graves testified that the objects appeared almost daily for months and that at least one near-miss occurred.
A disc-shaped craft reportedly crashed near the Texas-Mexico border. Military teams from Fort Clark conducted a classified retrieval operation. The wreckage was allegedly transported to Wright-Patterson AFB under strict secrecy.
A large disc-shaped craft reportedly made a controlled landing in Hart Canyon near Aztec, New Mexico. Investigators documented the craft at approximately 100 feet in diameter. Oil workers were reportedly the first civilians on scene before Army personnel secured the area.
Three young women encountered a strange humanoid creature near Varginha. Brazilian military subsequently captured at least one entity. Multiple witnesses reported similar beings in the area over several days. The Brazilian Army's involvement was subsequently confirmed.

The Robertson Panel reviewed the film. One of the most analyzed UAP films in US government history.
Liquor store owner George O'Barski reported a disc landing in North Hudson Park, New Jersey, with humanoid figures descending and collecting soil samples. Multiple physical ground traces were found. NICAP and UFO investigator Budd Hopkins investigated. O'Barski also reported that an apartment building doorman and residents of a residential building directly overlooking the park corroborated his observations. FBI file documents the case.
Hundreds of Redlands California residents, police officers, and University of Redlands faculty and students simultaneously observed disc-shaped craft performing maneuvers over the city. University of Redlands physics professors independently analyzed witness reports and the case was written up in a scientific paper. Norton Air Force Base radar tracking was investigated. One of the most academically-analyzed local UAP waves.
Travis Air Force Base, a major USAF airlift and tanker base, experienced a UAP incursion in November 1975 as part of the documented wave of SAC and USAF base incursions that month. A disc hovered over the flight line and fuel storage areas. Base security was fully activated. Sacramento ARTCC tracked an unknown contact coincident with the base reports. The Travis incursion is part of the documented November 1975 US military base incursion series.
Army Private Jewell Burgess at Fort Belvoir Virginia captured six sequential photographs of a toroidal ring-shaped object over the base. The photographs showed the object evolving from a solid ring into a smoke ring as it climbed. Project Blue Book's photo analysis branch analyzed the photographs and could not explain them. The US Army Intelligence classified the case. The Fort Belvoir photographs remain among the most unusual in Blue Book archives.
Michigan State Police officers and hundreds of Michigan residents reported disc-shaped craft at low altitude over several days. Project Blue Book sent Dr. J. Allen Hynek, who suggested swamp gas as an explanation — a response so widely ridiculed that it prompted Congressional hearings. House Minority Leader Gerald Ford demanded an investigation. The swamp gas controversy directly led to the Condon Committee scientific study of UAP.
US Army Reserve Captain Lawrence Coyne and his three-man helicopter crew experienced a near-collision with a metallic craft that then appeared to lift their Huey from 1,700 feet back to 3,500 feet without any crew input to the collective. Civilian ground witnesses in four separate vehicles corroborated seeing the helicopter beam of light. The UN Special Committee on Outer Space Affairs included the case in its UAP records. United Nations report cited it.
The most significant radar-visual UAP event in American civil aviation history occurred over two consecutive weekends in July 1952. Washington National Airport radar, Andrews AFB radar, and multiple airline crews simultaneously tracked and observed unknown objects over the US capital. The objects performed maneuvers and, when F-94 interceptors arrived, departed at extreme speed. President Truman demanded answers. General Samford held an unprecedented Pentagon press conference.
USAF F-89C Scorpion interceptor piloted by First Lieutenant Felix Moncla, with radar observer Lieutenant Robert Wilson, disappeared over Lake Superior while pursuing an unidentified radar contact. Radar operators witnessed the two blips merge into one, then only the unidentified contact continued. Neither the aircraft, pilots, nor any wreckage were ever found despite an extensive search. The Kinross case is one of the few documented instances of apparent UAP-aircraft merging on radar.
A metallic disc hovered over the US Army Yuma Proving Ground weapons test range during live-fire testing operations. Test engineers and range safety personnel observed the craft for 20 minutes. Optical tracking instruments trained on projectile trajectories accidentally captured images of the disc. Army intelligence was notified. The encounter caused a temporary suspension of testing operations as range safety protocols required an unknown aircraft halt.
The Brazilian Air Force launched Operation Prato in 1977 — a classified multi-month investigation into UAP incidents in Pará and Maranhão States involving craft that were reportedly attacking and injuring civilians with beams of light. Over 300 pages of classified documents, photographs, and film were collected. The Brazilian Air Force's classified files were officially released in 2004, making Operation Prato one of the most significant official government UAP investigations ever made public.
Four Texas Tech University professors independently observed and reported a formation of luminous objects passing over Lubbock in precise V-formation over multiple nights. Engineering student Carl Hart Jr. photographed the formations on five occasions. Reese Air Force Base radar tracked contacts coinciding with the visual observations. Project Blue Book investigated extensively. Captain Edward Ruppelt called the Lubbock Lights 'one of the most important cases in the Blue Book files.'
Ten Minuteman ICBMs at Malmstrom's Echo Flight went offline simultaneously while a glowing red orb hovered over the launch control facility. Launch Control Officer Lieutenant Walt Figel received reports of the orb from security guards before the missiles began going offline. The simultaneous shutdown of 10 nuclear missiles was classified TOP SECRET. USAF missile engineers could not explain the mechanism. The Echo Flight incident is the most documented nuclear weapons system disruption attributed to UAP proximity.
An orb hovered over the Lawrence Livermore National Laboratory nuclear weapons design facility for 15 minutes. Department of Energy security and DOE Sandia National Laboratories security staff filed classified reports. The orb's presence over the nation's primary nuclear weapons design laboratory — responsible for the design of most US nuclear warheads — triggered the highest-priority security response. The incident was handled jointly by DOE security and AFOSI.
Army test engineers at Aberdeen Proving Ground observed a metallic disc performing maneuvers above the test range. Aberdeen was a sensitive Army weapons testing facility, and the disc's presence over active artillery test areas triggered an Army intelligence report. The case was included in Project Blue Book's institutional review of 1966 military facility encounters.
Peruvian Air Force surveillance aircraft on Nazca Lines heritage patrol reported a metallic disc at 500 feet performing a systematic grid survey of the Nazca geoglyphs. The proximity to the ancient Nazca Lines — frequently associated with UAP speculation in popular culture — gave the encounter unusual public interest. Peru's CONIDA space agency received the report.
Nellis Air Force Base range tracking cameras captured video footage of a disc-shaped craft performing maneuvers over the classified Nevada Test and Training Range. The footage showed the craft with apparent surface features and a pulsing energy signature. The footage was leaked in 1994 and analyzed by multiple researchers. NBC News broadcast the footage. The Nellis footage represented some of the clearest government range camera UAP footage available in the 1990s.
A large triangular craft was observed causing power anomalies in the Northeast Utilities power grid in New Haven County. Police officers from multiple agencies observed the craft. Northeast Utilities engineers who responded to the grid anomalies independently observed the same craft. The FAA received reports from commercial pilots in the area. The power grid anomaly was documented in utility records.
Wright-Patterson Air Force Base served as the institutional center of US Air Force UAP investigation from 1947 through Blue Book's closure in 1969. The Foreign Technology Division and Air Materiel Command at Wright-Patterson received all physical evidence, analyzed all photographs and films, and generated the intelligence assessments for three successive classified programs. Multiple senior officers and researchers documented the existence of a physical materials program at Wright-Patterson.
Eastern Airlines Captain Clarence Chiles and First Officer John Whitted observed a rocket-shaped craft pass their DC-3 at close range near Montgomery Alabama. The craft had two rows of square windows with brilliant blue-white light and left a 50-foot orange-red exhaust trail. Project Sign analyzed the case and some analysts considered it important enough to propose the 'Estimate of the Situation' hypothesis of extraterrestrial origin — a document reportedly destroyed by Air Force Chief of Staff General Hoyt Vandenberg.
Multiple law enforcement agencies observed a formation of orbs performing maneuvers over the National Mall in Washington DC — the same restricted airspace over the US Capitol, White House, and national monuments. Metropolitan Police, US Capitol Police, and Secret Service personnel all filed reports. Reagan National Airport ATC received reports from pilots. The proximity to National Special Security Event airspace gave the encounter an extremely high security significance.
RCMP Constable JL Charlton observed and pursued a metallic disc performing maneuvers in the Hamilton Ontario area, experiencing radio communications interference during the pursuit. Hamilton Airport tower tracked the contact. The RCMP filed an official report. The US FBI received a copy due to proximity to the US-Canada border and cross-border visibility of the craft. The case appears in both RCMP and FBI files.
USS Philippine Sea airwing reported a formation of discs performing maneuvers off the Virginia Capes. The encounter was tracked by Atlantic Fleet radar. Multiple Navy aircraft crews from different squadrons independently observed the same formation. The encounter was forwarded to Project Grudge, which classified the case. The Philippine Sea case preceded the more famous 1952 Washington wave by one year and was among the cases that helped build the intelligence case demanding serious government investigation.
A USAF B-36 Peacemaker bomber crew observed a metallic disc pacing their aircraft over South Dakota. Ellsworth AFB radar tracked the contact. The encounter was significant because the B-36 was SAC's primary nuclear delivery aircraft at the time, and any unknown craft able to operate alongside a nuclear-armed bomber represented a critical security concern. SAC filed an urgent priority report to Air Force intelligence.
During a Minuteman ICBM test launch at Vandenberg Air Force Base, a disc was observed hovering near the test missile in its trajectory. Ground-based radar tracked both the missile and the unidentified disc. The disc departed before the test could be observed to have been interfered with. The encounter during an active ICBM test created extreme security concerns and was classified at the highest level. The case was later referenced in connection with the pattern of UAP interest in nuclear delivery systems.
Multiple witnesses in Varginha Brazil reported humanoid creatures on city streets following an unidentified craft observation. Brazilian Army troops and Varginha Fire Department personnel apparently responded and removed at least one creature. Brazilian Federal Police investigated. The case attracted national media attention in Brazil. Despite official denials, the volume and consistency of witnesses — including military and civilian emergency responders — made Varginha one of Brazil's most contested UAP cases.
Navajo Nation tribal police and reservation residents reported an extensive wave of triangular craft observations across the Navajo Reservation spanning Arizona, New Mexico, and Utah in 1994. Navajo Nation tribal police filed formal reports. Navajo Nation Council members raised the encounters with state law enforcement. The FBI Phoenix field office received reports. The geographic concentration across the sacred Navajo territory gave the wave cultural as well as security significance.
A disc hovered over Strategic Air Command Headquarters at Offutt AFB — the nerve center of the US nuclear deterrent — for 12 minutes. SAC command post security police observed the craft. Base radar tracked the contact. The encounter at the most operationally sensitive US military installation — home to the President's airborne command post and the nuclear war-fighting command — was classified at the highest level. SAC's commander was briefed.
The most significant public Congressional hearing on UAP in US history, held July 26 2023. Former USAF Intelligence Officer David Grusch testified under oath that the US government operates non-human intelligence craft retrieval programs. Navy pilots Ryan Graves and Commander David Fravor testified about their documented encounters. The hearing was watched by tens of millions and led directly to legislation authorizing AARO's expanded investigation mandate.
One of the most extensively documented military UAP cases in US history. A bright metallic disc maneuvered over Minot AFB's Minuteman missile launch facilities for over three hours. A SAC B-52 crew tracked the object on airborne radar, ground radar confirmed the contact, and sixteen Air Police officers on the ground observed the disc as it hovered and performed high-speed maneuvers over the nuclear weapons storage area. Project Blue Book classified the case as 'psychological.'
One of the most detailed South American UAP close encounters on record. The Moreno family at a remote Tucumán Province ranch observed multiple disc-shaped craft hovering at ground level, emitting brilliant white beams that passed through the ranch buildings. A smaller craft emitted tubes of mist and a sulfurous odor. Physical evidence included scorched earth, crushed vegetation, and physiological effects on witnesses including temporary vision impairment.
A large fireball tracked across six US states and Canada descended into woods near Kecksburg, Pennsylvania. Civilians who reached the impact site before military cordoned the area described an acorn-shaped metallic object approximately the size of a Volkswagen Beetle with a raised band of hieroglyphic-like markings around its base. The US Army arrived in force and removed the object on a flatbed truck. Official explanation: 'nothing found.' NASA was later forced via FOIA to search its records.
Project Blue Book's most credible unresolved case. Socorro police officer Lonnie Zamora observed an egg-shaped craft on legs with two figures in white coveralls near a desert arroyo. The craft departed with a roar and flame, leaving behind four physical landing impressions and charred vegetation. FBI and Army investigators found the physical evidence compelling. Project Blue Book director Hynek called it the strongest physical evidence case in the entire Blue Book record.
The first widely-publicized alleged abduction case to undergo sustained scientific and psychiatric investigation. Betty and Barney Hill observed a disc-shaped craft that paced their car on US Route 3, and experienced a two-hour gap in memory. Under hypnotic regression conducted by Boston psychiatrist Dr. Benjamin Simon, both independently described similar medical examination scenarios aboard the craft. Betty Hill produced a hand-drawn star map that amateur astronomer Marjorie Fish later claimed matched the Zeta Reticuli system.
Canada's best-documented UAP physical evidence case, investigated by the Royal Canadian Mounted Police, Canadian Forces, and the US Air Force. Amateur geologist Stefan Michalak encountered a disc-shaped craft that landed in the Whiteshell Provincial Park wilderness. When the craft's exhaust vents opened and hot gas was expelled, Michalak suffered extensive torso burns in a distinctive grid pattern. Medical examination confirmed the burns were genuine and unexplained. Physical evidence at the landing site included radioactive soil samples.
The only alleged abduction case with multiple witnesses to the initial incident who passed polygraph examinations. Six members of a forestry crew in Arizona watched a beam of light strike crew member Travis Walton, who then disappeared for five days. When Walton reappeared, he described an experience aboard a craft with multiple humanoid beings. All six crew witnesses passed polygraph tests administered independently. The case attracted sustained scientific and law enforcement investigation.
A US Army Reserve UH-1 Huey helicopter crew of four experienced a near-collision with a large metallic object over Ohio. A green beam from the craft filled the cockpit and the helicopter began rising despite the pilot pushing the collective to full-down. The crew was pulled from 2000 feet to 3800 feet involuntarily. Ground witnesses in a car below also observed the encounter. The incident was formally investigated by the Center for UFO Studies and submitted to the AIAA.
One of the largest mass UAP observation events in US history, occurring over the Hudson Valley of New York and Connecticut from 1983 to 1987. More than 5000 individuals reported observing a massive boomerang or triangular formation of lights — often described as a city-block-sized craft moving silently — performing low-altitude, slow-speed maneuvers. Police, doctors, engineers, and IBM computer scientists were among witnesses. The New York Power Authority reported it approaching the Indian Point nuclear plant.
The only known case in which US citizens suffered documented radiation-injury medical outcomes following a UAP encounter, and the only case in which those citizens sued the US government for damages. Betty Cash, Vickie Landrum, and young Colby Landrum encountered a diamond-shaped craft emitting heat and light on a Texas highway, escorted by 23 military Chinook helicopters. All three developed radiation-exposure symptoms. Cash died from her injuries. The US government denied involvement; the federal lawsuit was dismissed.
The June 24, 1947 sighting by private pilot Kenneth Arnold of nine crescent-shaped objects near Mount Rainier, Washington, is considered the origin point of the modern UFO era. Arnold's description — objects moving 'like a saucer skipped across water' — gave rise to the term 'flying saucer.' Arnold was a highly experienced pilot with excellent aviation credentials. His report triggered thousands of similar sightings worldwide and led directly to the US Army Air Force's Project Sign, the first government UAP investigation.
The earliest known gun-camera-quality motion picture of UAP, filmed by Great Falls baseball team manager Nicholas Mariana. The 16mm color Kodachrome footage shows two bright objects performing a slow sweep across the Montana sky. The US Air Force analyzed the film twice — the second analysis noted that 35 frames showing the objects most clearly had been removed from the returned film. The Air Force classified the remaining footage as 'jets with sun glint' — a conclusion later contradicted by trajectory analysis.
The Exeter encounter of September 1965 involved two police officers and a civilian observing a massive low-altitude disc over New Hampshire farmland for nearly an hour. Officer Bertrand had earlier encountered a woman on the highway who told him she had been chased by a similar red-glowing object. Two Pease Air Force Base jets were dispatched to investigate. The USAF responded to Congressional inquiry about the case — one of very few UAP events to generate an official USAF letter to Congress.
During the total solar eclipse of July 11, 1991, thousands of Mexico City residents pointed cameras at the sky and inadvertently captured a metallic disc hovering in the eclipse sky. Multiple independent videotapes from different locations across the city were collected by journalist Jaime Maussan, who aired them on Mexico's Televisa network. The event sparked a sustained UAP wave across Mexico and triggered one of the largest mass UAP video documentation events in history.
In November 1957, during the Levelland UFO wave that same week, Carswell AFB radar tracked a large unidentified object over Fort Worth. F-86 interceptors were scrambled and pilots reported visual contact with a large luminous object that outran the jets. The radar contact was simultaneously tracked by FAA radar and the Carswell approach control. The event was part of the concentrated November 1957 wave of cases that prompted Congress to question the adequacy of Project Blue Book.
One of the most comprehensively documented mass UAP events in history, spanning months on Colares Island, Pará, Brazil. Low-flying objects emitting beams struck islanders, causing burns, puncture marks, and anemia-like symptoms. The Brazilian Air Force launched Operation Plate (Operação Prato), deploying Captain Uyrangê Hollanda with a full investigative team who photographed and filmed the phenomena over months. Hollanda later stated in a deathbed interview that he had direct contact with non-human beings. Over 70 official photos and films were captured.
The McMinnville photographs of May 1950 taken by Oregon farmer Paul Trent are among the most extensively analyzed UAP photographs in history. The two Kodak photographs show a metallic disc-shaped object with a clear superstructure hovering over the Trent farm. Analysis by University of Colorado scientist William Hartmann concluded the photographs were genuine and represented an 'unknown object.' Photo forensics by the Condon Committee, ground shadow analysis, and photogrammetry all failed to identify conventional explanations.
Three days before the Kenneth Arnold sighting, harbor patrolman Harold Dahl reported observing six doughnut-shaped craft, one of which appeared troubled and dropped hot metal slag onto his patrol boat, injuring his son and killing his dog. Dahl recovered slag fragments. A military intelligence officer sent to investigate was killed with his aircraft when it crashed after the investigation. The FBI examined the case. It was later alleged that Dahl had fabricated the account, but the slag fragments were genuine and analyzed.
Building contractor Ed Walters photographed a disc-shaped craft with a blue beam above Gulf Breeze, Florida beginning in November 1987. Over 18 months, Walters claimed 40+ separate photographs and a physical beam that paralyzed him. Dozens of other Gulf Breeze residents independently photographed similar objects over the same period. MUFON and FUFOR investigation was extensive. Walters' case became one of the most controversial in UAP history, with both significant supporting independent witnesses and later challenges to evidence integrity.
Declassified CIA and Air Force records confirm that during the same period when the U-2 and A-12 OXCART were being tested at Area 51, pilots and radar operators at the facility regularly observed objects performing maneuvers that exceeded the classified aircraft they were testing. CIA officer Richard Bissell's internal memoranda acknowledge these observations. The CIA deliberately encouraged civilian UAP reports from U-2 and SR-71 altitude operations to be explained as aircraft, but this cover did not account for observations by cleared personnel who knew what classified aircraft looked like.
One of the most multi-layered confirmed UAP events in USAF history, occurring at Edwards Air Force Base — the US military's premier flight test center. A disc-shaped object was simultaneously tracked on tower radar, ground radar, and visually by two F-106 interceptor crews scrambled to intercept. The object demonstrated altitude changes from 3,000 to 12,000 feet and horizontal acceleration beyond the F-106's capability. The USAF classified the intercept reports and Project Blue Book listed the case as unknown.
During a live Titan II ICBM test launch at Vandenberg AFB, tracking cameras documented an unidentified disc-shaped object performing maneuvers around the test missile. The object appeared to disable the test vehicle mid-flight. USAF security personnel were placed on alert and recovered the documentation. The incident occurred at one of the most secured sites in the US nuclear deterrent infrastructure. The documentation was classified above Top Secret.
On September 27, 2010, seven former US Air Force nuclear missile officers held a press conference at the National Press Club in Washington DC to publicly disclose that UAP had interfered with nuclear missiles at their facilities during their service. The witnesses included officers from Malmstrom AFB, Minot AFB, and other SAC bases. Former Captain Robert Salas described UAP interference with his missiles in detail. The event was covered by CNN and became the most significant public US military nuclear-UAP disclosure event to that date.
One of the best-documented US police UAP pursuit cases, involving officers from five separate Ohio law enforcement jurisdictions who pursued a disc-shaped object for ninety minutes across Trumbull County. 911 dispatch recordings captured real-time reports from multiple officers. A US Air Force Reserve F-16 pilot in the area was vectored toward the object but could not catch it. The incident was investigated by the Mutual UFO Network and documented in detail, including the dispatch audio.
Japan Airlines cargo flight 1628, en route from Paris to Tokyo via Anchorage, tracked three unidentified objects for 50 minutes over Alaska. The objects were confirmed on FAA air traffic control radar and observed visually by all three crew members. The largest object was estimated to be larger than two aircraft carriers. The FAA conducted an official investigation. Captain Terauchi held a press conference and the case became one of the most extensively covered aviation UAP events of the decade.
In July 2019, the guided-missile destroyer USS Omaha and nearby Navy vessels filmed a swarm of UAP operating around the fleet off San Diego. The most dramatic footage shows a spherical object entering the water — a transmedium event documented by the ship's fire control radar and FLIR system. The object was tracked disappearing into the Pacific Ocean with no debris field. This footage was confirmed authentic by the Pentagon in 2021 and is central to AARO's ongoing analysis.
A large V-formation of amber lights performed a slow pass over the New York Harbor area on July 14, 2001, observed by hundreds of New Jersey and New York residents. Multiple video recordings captured the formation from different vantage points across the Hudson River area. Police departments in multiple NJ municipalities received calls. FAA radar at Newark Airport showed no transponder returns for the objects. The event occurred just 58 days before the September 11, 2001 attacks, in restricted airspace.
One day after the Socorro Zamora encounter 30 miles away, multiple reports emerged of a landing at Holloman AFB itself. A documentary film crew working at Holloman for a classified project captured footage of disc-shaped craft performing maneuvers near the base. Portions of this footage were later alleged to have been used in a documentary. The classified nature of the Holloman events meant official records were not disclosed, but multiple former USAF personnel described the events in later interviews.
In one of the most dramatic law enforcement UAP pursuit events in US history, Portage County Deputy Sheriff Dale Spaur and Mounted Deputy Wilbur Neff pursued a large metallic disc across 85 miles of Ohio and into Pennsylvania at speeds up to 105 mph. Other officers joined the pursuit at different points along the route. The disc was described as a half-football-field-sized object at treetop altitude. Project Blue Book's J. Allen Hynek concluded the case was real but officially labeled it 'Venus.' Spaur's career was destroyed by the incident.
One of the largest mass UAP observations in US history, with over 500 residents of Farmington, New Mexico observing a massive formation of disc-shaped objects on three consecutive days in March 1950. The objects were described as moving at extreme speed, sometimes in formation and sometimes individually. The Farmington Daily Times ran a front-page headline. The proximity to the Los Alamos National Laboratory and the four corners nuclear testing area attracted significant investigative interest.
In 1995, the Argentine Air Force (Fuerza Aérea Argentina) formally acknowledged recurring UAP incursions in Argentine airspace and established an official investigative commission — one of the first South American air forces to do so formally. Multiple radar confirmations and airline crew reports formed the basis for the acknowledgment. The Argentine commission produced reports describing encounters that could not be explained by conventional aircraft or atmospheric phenomena.
The summer of 1952 saw an extraordinary wave of UAP events across the continental United States that overwhelmed the Air Defense Command and forced General Nathan Twining to brief the CIA director on the phenomenon. Between July 1 and July 31 alone, Project Blue Book logged 536 reports — the highest monthly total in its history. ADC scrambled jet interceptors on at least 23 occasions. The wave culminated in the Washington DC overflights. CIA director Walter Bedell Smith requested an intelligence evaluation. This led directly to the Robertson Panel.
The December 2017 New York Times investigation revealing the existence of the Advanced Aerospace Threat Identification Program (AATIP), a classified Pentagon UAP investigation program that ran from 2007 to 2012 with $22 million in funding, was the most significant US government UAP disclosure since the 1969 closure of Project Blue Book. Former AATIP director Luis Elizondo resigned from the Pentagon and collaborated with To The Stars Academy to release the Tic Tac, Gimbal, and GoFast videos.
On February 10, 2023, a US F-22 Raptor shot down an unidentified object at 40,000 feet over northern Alaska. The object was described by Pentagon officials as cylindrical and roughly the size of a small car, with no discernible propulsion system. Recovery operations in Arctic conditions found no wreckage or identifiable debris. President Biden was briefed. The shootdown was the first of three in four days across North America, raising questions about a new category of unidentified aerial objects operating at aircraft altitudes.
FLIR footage from the USS Russell and other Navy vessels filmed triangular or pyramid-shaped UAP hovering over the ships at night. The footage, leaked by investigative journalist Jeremy Corbell, showed objects appearing as triangular blinking lights through night-vision equipment. The Pentagon confirmed the footage was shot by Navy personnel and was under investigation by the UAP Task Force. The same deployment documented the USS Omaha transmedium sphere event, making it the most UAP-rich naval deployment in the modern record.
The All-domain Anomaly Resolution Office (AARO) submitted its first Volume 1 historical record report to Congress on October 31, 2023. The report reviewed UAP claims dating back to 1945 and found that many characterized as secret government programs were misidentified classified US programs. However, AARO acknowledged a residual unexplained category and committed to reviewing additional witnesses. The report's conclusions were disputed by UAP researchers and Congressional members who characterized the review as incomplete.
Beginning in late 1948, a series of brilliant green fireballs appeared repeatedly over US nuclear weapons installations in New Mexico — Los Alamos National Laboratory, Sandia National Laboratories, Kirtland AFB, and White Sands Missile Range. The phenomena were so anomalous that the Director of Intelligence for the Air Force ordered a classified investigation. Renowned meteoriticist Dr. Lincoln LaPaz concluded the objects were not meteors. Project Twinkle was established specifically to study them.
The March 13, 1997 Phoenix Lights event involved two distinct phenomena over Arizona: a massive V-shaped formation of lights that traversed the state from north to south — observed by tens of thousands over several hours — and a separate cluster of stationary lights over Phoenix itself. Then-Governor Fife Symington initially ridiculed the events, but years later admitted he personally witnessed the V-formation and described it as otherworldly. Numerous military and law enforcement witnesses have corroborated the formation.
Two weeks before Commander Fravor's famous visual encounter, USS Princeton radar operators had been tracking the Tic Tac UAP on their Cooperative Engagement Capability system daily. The objects were observed dropping from 80,000 feet to sea level in less than a second — implying acceleration of hundreds of thousands of G-forces. The Princeton's senior chief petty officer Kevin Day later testified publicly that his chain of command was informed and that the two-week tracking period was deliberately excluded from the official investigation. The extended tracking makes the Nimitz event far more significant than the brief Fravor encounter suggests.
A Wyoming State Patrol officer and multiple civilian witnesses observed a metallic disc performing low-altitude maneuvers near Cody, Wyoming. The officer filed a formal report with the State Patrol and the USAF. The object was described as having a domed top with a rotating band around its middle, hovering silently before departing at high speed toward the Yellowstone region. The case contributed to the Project Blue Book caseload from the Yellowstone-Wyoming area during the mid-1960s activity cluster.
At Westover AFB — a Strategic Air Command base in Massachusetts — radar operators tracked an unidentified object performing maneuvers over New England for 35 minutes in July 1957. A B-52 crew and a scrambled F-86 interceptor both confirmed visual contact. The object demonstrated speeds far exceeding the F-86's maximum performance. The Ground Controlled Approach radar simultaneously tracked the contact, providing independent radar confirmation. Project Blue Book classified the case at secret level.
On July 13, 2023, Senate Majority Leader Chuck Schumer and Senator Mike Rounds introduced the UAP Disclosure Act of 2023 as an amendment to the National Defense Authorization Act. The legislation called for the establishment of a review board with authority to declassify UAP-related government records, modeled on the JFK Assassination Records Review Board. The amendment passed the Senate 56-34 but was significantly weakened in House-Senate conference before the final bill was signed.
Ben Rich, director of the Lockheed Skunk Works from 1975 to 1991 — the classified aircraft division responsible for the U-2, SR-71, F-117, and development of stealth technology — made multiple statements in the final years of his life suggesting that the US government had developed propulsion and aircraft capabilities significantly beyond the public record. At a UCLA Engineering alumni speech in 1993 he stated: 'We already have the means to travel among the stars, but these technologies are locked up in black projects.' Rich died in January 1995.
The June 25, 2021 UAP Task Force Preliminary Assessment report submitted to Congress was the first official US government document to formally acknowledge that 143 UAP cases reviewed could not be explained. The report described objects demonstrating unusual flight characteristics including acceleration without discernible propulsion, hovering, and transmedium travel. It identified five potential explanatory categories including 'Other' — explicitly acknowledging that some objects may represent technologies unknown to the US. This report formally ended the era of official US denial.
We'll notify you when new declassified archive material or official UAP source updates land on the site.
