Every indexed declassified UAP case where unknown shape was documented by official government sources — NARA RG 615, AARO, NASA, FBI, and DoD PURSUE program releases.
Astronaut Frank Borman reported a 'bogey' keeping pace with Gemini 7 in orbit. Audio recording included in the public archive record set. NASA classified as 'unexplained orbital anomaly'.
Photograph shows five unexplained phenomena above the lunar horizon. Pete Conrad's filed report describes an object maintaining parallel course for approximately 40 minutes during lunar orbit.
Commercial PanAm aircraft at 41,000 ft encountered an object performing circles, corkscrews and 90-degree turns at rapid rates. State Department diplomatic cable filed. No military explanation found.
Object tracked making multiple precise 90-degree turns at approximately 80 mph over Greek airspace. Turns executed with zero radius — inconsistent with any known aircraft. State Dept cable filed via Athens embassy.
Internal military memo describes 'one possible small UAP' operating near US military assets in Iraq at ~80,000 ft altitude. Performed maneuvers inconsistent with any known aerial vehicle.
UAP entered the ocean without deceleration, tracked by sonar at 900m depth for 11 minutes, re-emerged and departed at hypersonic speed. First officially documented transmedium UAP event.
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.
Over three nights, USAF security personnel at RAF Woodbridge reported a structured craft in Rendlesham Forest. Deputy Base Commander Lt. Col. Charles Halt filed an official memorandum to UK Ministry of Defence. Ground traces, radiation readings, and Halt's own audio recording of the event are included in the 2026 declassified archive.
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.
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.'
Radar operators at RAF Bentwaters and Lakenheath tracked multiple unknown objects over East Anglia for several hours. A USAF Venom jet interceptor was guided by radar toward one object; the pilot briefly achieved visual contact, then the object moved behind the aircraft and mirrored its every turn — effectively pursuing the interceptor. The pilot could not shake the object through multiple violent maneuvers. The Scientific Advisory Panel (Robertson Panel) evaluated this case in 2026 archive release notes as 'unexplained.'
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.
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.
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.
Australian pilot Frederick Valentich radioed Melbourne Air Traffic Control to report a metallic craft with a green light orbiting his Cessna over Bass Strait. His last transmission described the object hovering above him and his engine beginning to malfunction. A final metallic scraping sound was recorded on the ATC tape — then silence. Neither Valentich nor his aircraft was ever found. The Australian Department of Transport investigation found no explanation.
Iberia Airlines Flight IB-297 made an emergency landing at Valencia's Manises Airport after objects with brilliant red lights nearly collided with the aircraft over the Mediterranean. The Spanish Air Force scrambled a Mirage F-1, whose pilot also observed the objects and reported they outperformed his aircraft before disappearing. The Spanish Air Ministry's official report classified the incident CONFIDENTIAL — it is cited in Spain's partial UAP record disclosure.
Japan's Ministry of Defense issued its first official protocol for JASDF pilots to document UAP encounters — an acknowledgment that unidentified objects had been observed by JSDF personnel that could not be attributed to foreign aircraft. The policy was directly triggered by JSDF pilot reports of objects outperforming Japanese fighters. Japan subsequently publicly acknowledged UAP encounters in parliamentary testimony.
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.
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.
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.
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.
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 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.
Italian passenger jet Itavia Flight 870 crashed into the Tyrrhenian Sea on June 27, 1980, killing 81 people. A 30-year Italian parliamentary and judicial investigation concluded the aircraft was destroyed amid aerial military activity involving UAPs or unidentified military aircraft. French radar and Italian Air Force radar showed unidentified objects in the same airspace. Italian courts held the government accountable for withholding evidence.
A Chilean Navy helicopter crew filmed an unidentified object on infrared for approximately 9 minutes. The Chilean government's official UAP investigation body CEFAA analyzed the footage for two years and concluded the object was 'a highly accelerated, solid, hot object' that could not be identified as any known aircraft. The footage was released publicly by CEFAA in January 2017 with a formal statement confirming the object is unexplained.
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.
Multiple commercial airline crews reported bright objects moving at extraordinary speed over the Atlantic Ocean west of Ireland on November 9, 2018. Shannon Air Traffic Control received the radio reports. The Irish Aviation Authority (IAA) opened a formal investigation. The primary witness, an Aer Lingus captain, described a bright light that 'rocketed up' and then split. The IAA investigation concluded the objects were real and moving at exceptional speed but could not identify them.
In September 2021, the Russian Ministry of Defence issued internal directive updates requiring formal reporting of anomalous aerial objects by Air and Space Forces personnel. Russian state media (TASS and Interfax) reported the directive publicly. Senior Russian Air and Space Forces officers acknowledged in official statements that unexplained aerial objects had been detected and that systematic documentation was now required. The directive paralleled similar reporting reforms by the US Navy (2019) and JSDF (2020).
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.
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.
Beginning in 2018, Norwegian, Swedish, and Finnish military authorities documented a sustained series of UAP and unidentified drone incursions over sensitive NATO installations including the Andøya Space Center, Forsmark nuclear power plant, Norwegian oil platforms, and multiple military bases. Some objects were tracked on radar but not visually identified. Multi-nation NATO investigation teams were formed. No state actor was confirmed responsible.
In 2010, the New Zealand Defence Force released 2,000 pages of classified UFO files spanning 1952–1984. The release was the largest official New Zealand government UAP document release. The files included RNZAF pilot reports, radar tracking data, witness statements, and official investigations. Many cases remained officially unexplained. The files are accessible through Archives New Zealand.
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.
The USS Kitty Hawk carrier strike group operating in the Pacific documented UAP encounters in late 2003 that preceded the famous 2004 Nimitz encounters by less than a year. VF-154 Black Knights F-14D crews reported encounters with unidentified objects that disappeared on radar approach. The incidents were reported through standard military channels. AARO incorporated the Kitty Hawk strike group UAP reports in its historical database.
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.
The USS Princeton guided-missile cruiser, acting as the air warfare command ship for the Nimitz Carrier Strike Group, tracked anomalous radar contacts for approximately two weeks before the now-famous Tic-Tac visual encounter on November 14, 2004. Senior Chief Kevin Day documented the tracks showing objects dropping from 80,000 feet to sea level in approximately 0.78 seconds — an acceleration that would require forces of thousands of G's. Day later testified publicly about the radar data.
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.
On August 13, 1956, RAF Bentwaters Ground Controlled Approach (GCA) radar and RAF Lakenheath radar both tracked unidentified objects performing extreme maneuvers over Suffolk, England. USAF F-86D Sabre jets were scrambled. One pilot achieved radar lock but the object reversed and got on his tail. The object was tracked at speeds approaching 4,000 mph. The Condon Committee called this case 'the most puzzling and unusual case in the radar-visual UFO file.'
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.
Between 2008 and 2012, the UK Ministry of Defence released over 6,700 pages of classified UAP files covering 1978–2007 through the UK National Archives. The release included RAF pilot reports, MoD intelligence assessments, and public correspondence. The files were released in batches under the Freedom of Information Act. The UK MoD's own assessment documents acknowledged that some UAP reports defied conventional explanation and warranted scientific investigation.
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.
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.
AARO's first Historical Record report to Congress in 2023 compiled UAP encounters from 1945–2023 and acknowledged for the first time that some cases involved objects 'demonstrating apparent capabilities beyond known US technology.' The report became the first official DoD historical compilation of UAP encounters.
A massive jellyfish-shaped luminous object hovered over Petrozavodsk, Soviet Karelia, emitting pencil-thin rays of light that burned circular holes in windows. Simultaneously observed by Finnish ATC across the border. TASS news agency reported it — the only UAP incident officially acknowledged in Soviet state media. Extensively studied by Soviet Academy of Sciences.
Over 2,000 reports of rocket-like objects crossed Scandinavia in 1946, predating the modern UAP era. Swedish military radar confirmed metallic contacts. The Swedish Defence Staff requested US and UK assistance. The CIA predecessor OSS investigated. Military fragments recovered from Lake Kölmjärv. One of the first intelligence-agency UAP investigations in history.
Follow-up physical evidence investigation at Rendlesham Forest by USAF Deputy Base Commander Lt. Col. Charles Halt over three nights. Halt's cassette tape recording made in real time documents radiation readings at ground traces and a craft performing maneuvers over the weapons storage area. Halt filed a memo to the Ministry of Defence, later released under the UK's Freedom of Information Act. Sergeant Penniston's notebook described binary codes he copied from symbols on the craft.
Dozens of residents of Stephenville and Erath County Texas reported an enormous silent craft with multiple lights tracked toward Crawford Texas — site of President George W. Bush's Prairie Chapel Ranch — in January 2008. MUFON received over 50 reports. The FAA confirmed an airspace anomaly. Radar data obtained by MUFON showed an unidentified track over the restricted airspace around the Presidential ranch.
Residents of Kokomo Indiana reported powerful unexplained booming sounds and vibrations coinciding with UAP observations on multiple days in early 2012. Howard County Emergency Management investigated. The USGS recorded seismic anomalies. Air Force Base Wright-Patterson researchers dispatched. The phenomenon ended as abruptly as it began, with no official explanation issued despite multiple agency investigations.
Multiple witnesses observed a craft crash into Shag Harbour, Nova Scotia. The RCMP, Canadian Coast Guard, and Royal Canadian Navy responded. Divers found nothing at the crash site. Declassified Canadian government documents show the incident was classified. US Navy vessels participated in the search. Witness testimony from Canadian Navy divers who surfaced the retrieval operation at a second location emerged in the 1990s. Canada's most documented possible crash retrieval.
Pilot Frederick Valentich reported a large unidentified craft with four bright lights orbiting his Cessna 182 over Bass Strait in a live radio transmission to Melbourne Flight Service. His final transmission was preceded by a metallic scraping sound. Valentich and his aircraft were never found. RAAF investigation could not explain the encounter or the disappearance. One of the most studied aviation UAP disappearances in history.
A LAN Chile Boeing 767 approaching Bariloche experienced navigation and electrical anomalies when a luminous object tracked the aircraft from the front. Simultaneously, Argentine Air Force base lights in Bariloche went dark. Bariloche ATC confirmed the encounter. Argentina's national Commission for Aerospace Phenomena studied the case and concluded it was authentic.
On the first night of the Rendlesham Forest incident, USAF Sergeant Jim Penniston and Airman John Burroughs approached a triangular craft in the forest to within arm's length. Penniston placed his hands on the craft's surface and recorded symbols in his notebook. He reported receiving a mental download of binary code. The notebook was submitted as evidence. Penniston later testified before Congress in 2023.
Canadian Naval vessel HMCS Nipigon tracked an unknown subsurface contact in Lake Ontario for 40 minutes that subsequently breached the surface and departed aerially. Sonar operators described a cylindrical object moving at 75 knots underwater. US Navy research vessels in the area also tracked the contact. The FBI was notified due to proximity to the US-Canada border and the Fitzpatrick nuclear facility.
The Halt memo — Lt. Col. Charles Halt's 1981 official memorandum to the UK Ministry of Defence documenting the Rendlesham Forest incidents — was obtained by researcher Robert Todd through FOIA in 1983 and entered the public record. The memo described the craft, radiation readings, and aerial maneuvers. It became the most studied official UAP document of the 1980s and remains in active use by Congressional UAP investigators.
A 15-page document purportedly recording a 2002 meeting between astrophysicist Dr. Eric Davis and retired DIA Director Admiral Thomas Wilson circulated in 2019. Admiral Wilson allegedly described being denied access to a Special Access Program involving non-human craft materials. The document was confirmed as originating from the estate of Dr. Edgar Mitchell by researchers. Its authenticity remains contested but it prompted Congressional investigation interest.
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.
In February 2023, during the same week the US military shot down multiple unidentified objects over North America, Chinese state media reported that PLAAF was tracking an unidentified flying object over Wuhan. Chinese authorities ordered preparations to shoot it down. The simultaneous global UAP shootdown/tracking events in the same week across multiple nations drew significant international intelligence attention. The coordination coincidence remains unexplained.
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.
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.
In the hours before and after the famous Chelyabinsk meteor on February 15, 2013, Russian air defense reported multiple unidentified contacts in the Chelyabinsk Oblast airspace that were distinct from the meteor. Russian Air Defence Forces and civilian witnesses in the region had been reporting anomalous lights for the preceding 48 hours. The Russian Ministry of Emergency Situations and Russian Air Defence officially investigated the pre-meteor anomalous contacts.
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.
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.
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.
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.
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.
The Tunguska explosion of June 30, 1908 — the largest impact event in recorded history — has generated persistent debate about whether the trajectory of the incoming object was consistent with a natural bolide or showed evidence of controlled flight. Russian scientist Alexei Zolotov published research suggesting the trajectory showed an anomalous correction inconsistent with a freely-falling body. The lack of recovered meteorite material and the unusual airburst characteristics have kept the event in the UAP-adjacent literature for over a century.
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.
