• DOCUMENTED Japan issued a formal SDF reporting procedure in September 2020. Then-Defense Minister Taro Kono announced on 14 September 2020 that the Ministry of Defense had established a protocol requiring Self-Defense Forces personnel who encounter unidentified flying objects in Japanese airspace to record the encounter and pass the material up for analysis. It was explicitly framed as a response to the US Department of Defense's April 2020 release of three Navy UAP videos.
• DOCUMENTED The stated purpose was information collection, not UFO-hunting. At his press conference the following day Kono characterised the measure as collecting information on unidentified objects rather than searching for craft from space. He had previously said publicly that he did not personally believe in UFOs — the protocol was an airspace-awareness measure sitting alongside Japan's existing scramble regime against Chinese and Russian aircraft.
• UNSUPPORTED Claims that the protocol was prompted by a specific Japanese military encounter. No Japanese SDF UAP encounter has been officially released to justify the directive, and the MoD has not published a report tally, a case file, or any imagery under the protocol in the six years since. Anyone asserting a triggering incident has not produced the document.
• DOCUMENTED Japan has a much older aviation case with a paper trail. The 17 November 1986 Japan Air Lines Flight 1628 incident over Alaska is documented in FAA records, not Japanese ones — captain Kenju Terauchi's report was investigated by the US Federal Aviation Administration, whose division chief John Callahan later spoke about it publicly. The FAA's formal position was that it could not confirm an object; skeptics including Philip Klass and James Oberg proposed Jupiter and Mars plus reflected moonlight off ice crystals. Note the asymmetry: the "Japanese" case is preserved because a US agency filed it.

• DOCUMENTED Australia ran an official channel called "Unusual Aerial Sightings" (UAS), then closed it. The Royal Australian Air Force accepted and assessed UAS reports from the 1950s. It ceased investigating them by 1996. The governing policy, Defence Instruction (General) ADMIN 55-1, was last reviewed in November 2003 and formally cancelled on 25 March 2013 — released in Defence FOI documents. Australia has had no official UAP reporting mechanism since.
• DOCUMENTED The files went to the National Archives of Australia in 2008 — and some cannot be found. Defence transferred its UAS holdings to the NAA; when the location of specific records was queried again in 2011, Defence was unable to verify where certain files were. Missing files are a documented archival fact. They are not evidence of a cover-up, and they are not evidence there wasn't one — they are evidence of poor records management, which is the boring and usual explanation for gaps in every national archive.
• DISPUTED Westall, 6 April 1966. Students and staff at Westall High School in Clayton South, Melbourne reported a domed, silver-grey object descending near The Grange. Air force personnel visited the site on 9 April 1966 and reported nothing of interest. Proposed explanations: a weather balloon released from Laverton (The Age, 7 April 1966); a HIBAL high-altitude test balloon blown off course from Mildura, based on National Archives documents located by researcher Keith Basterfield; a towed nylon target drogue (Brian Dunning, who monetises skeptical content via the Skeptoid podcast); and memory contamination across decades of retellings (Richard Saunders). Proponents counter that no single balloon flight has been matched to the date and time. Nobody has closed it.
• DISPUTED Frederick Valentich, 21 October 1978. A 20-year-old pilot flying a Cessna 182L (VH-DSJ) over Bass Strait radioed Melbourne that an unidentified aircraft with four bright landing lights and a green light was above him, said "it's not an aircraft," and transmitted metallic scraping sounds before contact ended. Neither pilot nor aircraft was recovered. The Department of Transport air safety investigation concluded the disappearance was presumed fatal, cause not determined. Prosaic candidates: a graveyard-spiral disorientation event in which he saw his own lights or celestial bodies (Venus, Mars, Mercury, Antares) while inverted — argued by James McGaha and Joe Nickell, both affiliated with the Committee for Skeptical Inquiry, which publishes Skeptical Inquirer; and a staged disappearance, given the aircraft's fuel range. Note that a missing-aircraft case with no wreckage cannot be resolved by argument, only by wreckage.

• DOCUMENTED Project Magnet, approved 2 December 1950. Run by Wilbert Brockhouse Smith, a senior radio engineer in Transport Canada's Broadcast and Measurements Section. It operated officially until mid-1954 and informally, on Smith's own time, until his death in 1962. Smith opened a small observation station at Shirley's Bay outside Ottawa in October 1952.
• DOCUMENTED Smith's conclusions were far outside what his own evidence supported — and Canada's government knew it. His June 1952 interim and 1953 reports asserted that UFOs were probably extraterrestrial and probably used magnetic propulsion. Smith also stated he had made telepathic contact with extraterrestrials and founded the Ottawa New Sciences Club. Transport Canada did not endorse his conclusions and the project was wound up. This is the cleanest available example of an official government UFO programme reaching an ET conclusion — and it is worthless as evidence, because the conclusion came from the investigator's prior beliefs, not from his data.
• DOCUMENTED Project Second Storey, established April 1952. A committee of scientists and military officers convened under the Defence Research Board that met periodically to assess Canadian UFO reports; Smith briefed it. It ran to about 1954 and produced no finding of unusual technology. It is routinely, and wrongly, described online as a "secret Canadian UFO agency" — it was a small interdepartmental review panel.
• DISPUTED Falcon Lake, 20 May 1967. Stefan Michalak, an industrial mechanic prospecting in Whiteshell Provincial Park, Manitoba, reported two glowing objects, one of which landed; he said he approached, touched hot metal, and was struck by a blast of hot gas from a grid of vents, leaving a grid-patterned burn on his chest. The RCMP, RCAF, Department of National Defence and Department of National Health and Welfare all investigated — Canada's most heavily documented UFO case by government paperwork volume. Findings both ways: soil collected on 26 June 1967 tested significantly radioactive, but chemists attributed the radioactivity to contamination by commercially available radium-based luminous paint, and site radiation was judged no danger to life. Skeptical positions include prior alcohol consumption noted by police, a Mayo Clinic psychiatrist's 1968 assessment that later grid marks were factitial (self-inflicted), and a possible motive involving a disputed mineral claim. Michalak maintained his account to his death in 1999; his son Stan Michalak co-authored a 2018 book on the case, which is a commercial stake worth stating.
• DOCUMENTED Canada re-entered the field in 2025 — as a data-management problem, not a mystery. The Office of the Chief Science Advisor of Canada ran the Sky Canada Project from 2023 and published "Management of Public Reporting of Unidentified Aerial Phenomena in Canada" in 2025 (preliminary version January 2025, final version mid-2025). Its scope was explicitly limited: it reviewed how public UAP reports are handled, did not collect firsthand evidence, and stated it was neither trying to establish nor refute extraterrestrial visitation. Its core finding was that Canadian UAP reporting is fragmented across Transport Canada, NAV CANADA, the RCMP, DND and private researchers, with no single accountable service; its central recommendation was to designate a federal body to receive, triage and publish UAP reports.
• DOCUMENTED Canada's actual UAP dataset is privately run. The annual Canadian UFO Survey has been compiled since 1989 by Ufology Research (Chris Rutkowski and colleagues), aggregating civilian, police and aviation reports. It is the longest continuous national UAP dataset in the world and it belongs to a hobbyist organisation, not a government. Rutkowski has authored multiple commercially published books on the subject — a stake to note, though he is on record consistently arguing that most reports resolve to prosaic causes.

• DOCUMENTED The Soviet Union ran a genuine, sustained state UAP programme for about thirteen years. Following a directive from the USSR Military-Industrial Commission, two parallel programmes were launched in 1978: Setka-MO ("Grid — Ministry of Defence") and Setka-AN ("Grid — Academy of Sciences"). They ran until roughly 1990. Participants Yuli Platov and Boris Sokolov published an account after the collapse of the USSR: "Study of Unidentified Flying Objects in the Soviet Union," Herald of the Russian Academy of Sciences, 2000. This is the best primary-adjacent source in existence on a communist-bloc UAP programme and it is in English.
• DOCUMENTED The programme's own conclusion was mundane. Platov and Sokolov report roughly 3,000 collected observations over the programme's life, with the overwhelming majority attributed to rocket and missile launches, high-altitude balloons and related military activity — a direct consequence of the USSR launching a great deal of hardware from sites the public knew nothing about. A residue of a few hundred cases was left unexplained. The authors did not conclude anything extraterrestrial. Unexplained means unexplained.
• RESOLVED The Petrozavodsk phenomenon, 20 September 1977. A vast luminous "jellyfish" was seen over Karelia around 04:00 local time and reported across a corridor stretching from Scandinavia to the Soviet Far East. A 1977 preliminary Academy of Sciences report said the phenomenon could not be satisfactorily understood on available data, and by December 1978 the Academy had compiled 85 reports. The explanation: American space journalist James Oberg matched it to the launch of the Kosmos-955 satellite from Plesetsk Cosmodrome at approximately 03:58 local time the same morning, the display being exhaust plume expansion illuminated as the vehicle left Earth's shadow. Yuli Platov — the Soviet investigator — publicly endorsed this explanation in 1984. Note who resolved it: an outside skeptic, confirmed by the insider. Oberg is a longtime commercially published space author and debunker, which is a stake; it is also not a reason to reject an explanation that the responsible Soviet scientist accepted.
• DOCUMENTED Petrozavodsk is why Setka exists. The event's scale, and the Academy's inability to explain it in 1977, is the proximate cause of the 1978 programme. The causal chain runs: a secret launch produced a spectacular sky display → the state could not explain its own activity to itself → it funded thirteen years of study → the study concluded the cause was mostly its own launches. That loop is the single most instructive thing in this section.
• DISPUTED The "Blue Folder" (Синяя папка). Accounts hold that in late 1991 the KGB released a compilation of around 124 pages of UAP-related material — military depositions, witness statements and sketches, covering observations across multiple Soviet regions in the 1980s — to cosmonaut Pavel Popovich, and that copies subsequently reached Western researchers including journalist George Knapp during a 1993 trip to Russia. That some Soviet-era UAP paperwork was released and circulated is not seriously contested. What is contested is provenance and completeness: analysts have noted that the circulating "Russian UFO files" corpus mixes authentic official documents with material of unclear or fabricated origin, and no independent chain of custody has been published for the folder as a whole. Popovich was honorary president of a Russian ufology association — an institutional stake. Knapp has built a long broadcast and documentary career on this material — also a stake.
• UNSUPPORTED Claims that the USSR or Russia recovered or reverse-engineered non-human craft. This circulates widely, sometimes attached to alleged follow-on programme names such as "Nit'" (Thread). No document, no photograph, no named custodian and no chain of custody has ever been produced. The people making the claim are typically Western media figures citing anonymous Russian sources, or Russian ufology associations with subscriber bases. What is missing is any primary document — and the Platov/Sokolov account, written by people who ran the actual programme, describes no such thing.

• DOCUMENTED A PLA researcher described a Chinese military UAP effort in an open publication. Chen Li of the PLA Air Force Early Warning Academy authored a report, dated 2019 and surfaced in Western media in 2021, describing a People's Liberation Army task force handling reports of "unidentified air conditions" (不明空情, UAC) — the Chinese military term, which is closer to "unidentified air situation" than to "UFO" and carries no exotic connotation. The report described a tiered reporting flow drawing on both military and civilian sightings, and stated that machine-learning tools were being applied to the sighting dataset because the volume had outgrown human analysts.
• TESTIMONY What the AI is claimed to do. Chen's report stated that automated analysis was used to separate explicable observations — aircraft, balloons, birds, launch debris — from a residual unexplained set. Specific accuracy figures attributed to the system in secondary coverage have not been independently verified against the original Chinese-language document, and the paper itself is a conference/institutional report, not a peer-reviewed result. Treat the capability claim as an assertion by a serving officer about his own service's tooling.
• UNSUPPORTED "China confirmed it has a UFO task force" as a claim about extraterrestrials. Widely repeated in Anglophone media. What is actually documented is an air-defence identification function, which every capable air force runs under some name — the US equivalents are NORAD's identification process and, since 2022, AARO. China's Ministry of National Defense has not issued a statement about non-human craft, and no Chinese official document describing a UAP encounter has been published. Reading "unidentified air situation" as "aliens" is a translation artefact.
• DOCUMENTED The structural point about China. There is no public Chinese UAP reporting mechanism, no FOIA-equivalent that reaches military records, and no released case files. Whatever China holds is not discoverable by the methods that produced the American, British, French and Brazilian record. Absence of Chinese data in global datasets reflects the absence of a disclosure regime, not the absence of sightings.

• DOCUMENTED The incident is documented by the United States, not Iran. A US Defense Intelligence Agency Defense Information Report, prepared from Imperial Iranian Air Force accounts by personnel at the US Defense Attaché Office in Tehran in October 1976, describes the events of the night of 18–19 September 1976. It was released under FOIA and is the reason the case is citable at all. The DIA evaluation attached to the report calls it an outstanding report meeting the criteria necessary for a valid study of the UFO phenomenon — a US intelligence assessment of report quality, not a US endorsement of any explanation.
• TESTIMONY What the crews reported. Two IIAF F-4E Phantom II interceptors were scrambled from Shahrokhi Air Base. The first, flown by Lt. Yaddi Nazeri, reportedly lost instrumentation and UHF/intercom communications at about 25 nautical miles from the object and recovered them on turning away. The second, flown by Maj. Parviz Jafari with Lt. Jalal Damirian, reported acquiring a radar lock at about 27 nautical miles, described intense red, green, orange and blue lights, and stated that his weapons control panel and communications failed as he attempted to fire an AIM-9 Sidewinder at a smaller object that had detached. Jafari testified publicly to this account, including at a National Press Club event in Washington in 2007 organised by advocates who publish commercially on the subject. The fact of the testimony is solid; the events described rest on the aircrew's word plus the contemporaneous US report of what they said.
• DISPUTED The prosaic explanation, and the case against it. Philip J. Klass — Aviation Week senior editor and the era's most prolific published debunker, with an explicit financial and reputational stake in skeptical books — argued the crews initially misidentified Jupiter, that the first F-4 had a documented history of electrical faults and poor maintenance, and that the September date coincided with the Gamma Piscids and Southern Piscids meteor showers. James Oberg has advanced similar astronomical explanations. Critics respond that Jupiter's elevation and the reported relative motion do not fit, that two independent aircraft suffering correlated avionics failures is not accounted for by one aircraft's maintenance record, and that a radar lock is not a meteor. Neither side has closed it. A separately noted detail — a beeping transponder-like device recovered near the reported landing area was traced to a US C-141, possibly shed in mountain turbulence — is a resolved sub-element, not a resolution of the case.
• DOCUMENTED Iran has published nothing. No Iranian government file on the 1976 incident has ever been released, before or after the 1979 revolution. Every primary document available comes from the US intelligence chain. This is the pattern for most of the world.

• RESOLVED Ladakh, August 2012 – February 2013. Indian Army and Indo-Tibetan Border Police units near Pangong Tso, on the disputed Chinese frontier, logged on the order of 329 sightings of luminous objects crossing from Chinese territory over roughly six months. They were assessed internally as possible Chinese drones or surveillance craft — a serious matter on a contested border.
• RESOLVED The explanation was Jupiter and Venus. A team from the Indian Institute of Astrophysics travelled to Ladakh with telescopes and established that the "objects" were the planets Jupiter and Venus, their apparent motion exaggerated by atmospheric refraction, high altitude and long observation from fixed posts. The resolution was published in the astronomical literature and reported in the Indian press in 2013.
• DOCUMENTED Why this case matters more than most. Trained military observers, in a high-tension theatre, generated hundreds of reports over six months against two of the brightest objects in the sky. The proximate risk was not aliens but a border incident. It is the strongest available demonstration that observer training does not confer immunity to misidentification, and that the fix is instrumentation and expert review, not credentials. Anyone citing "trained military observers" as though the phrase settles a case has to get past Ladakh first.
• DOCUMENTED India has no UAP reporting mechanism. There is no Indian equivalent of AARO, GEIPAN or the former RAAF UAS channel. Military sightings are handled internally as air-defence matters and are not published.

• DOCUMENTED Grenada put UFOs on the UN agenda. Prime Minister Sir Eric Gairy campaigned from 1977 for the establishment of a UN agency or department to coordinate research into unidentified flying objects. On 27 November 1978 he led a delegation addressing the UN — the group included scientists and an astronaut. Participants named in accounts of the 1977–78 proceedings include Grenada's UN representative Wellington Friday, astronomer J. Allen Hynek (founder of the Center for UFO Studies), Jacques Vallée (author, later a venture capitalist), and Lt. Col. Lawrence Coyne of the 1973 Ohio Army Reserve helicopter incident.
• DOCUMENTED Decision 33/426, adopted 18 December 1978. UN document symbol A/DEC/33/426, titled "Establishment of an agency or a department of the United Nations for undertaking, co-ordinating and disseminating the results of research into unidentified flying objects and related phenomena." What it actually did was far less than its title: it took note of Grenada's statements and draft resolutions, invited interested Member States to take appropriate steps to coordinate on a national level scientific research and investigation into extraterrestrial life including UFOs, asked those states to inform the Secretary-General of their observations and evaluations, and transmitted Grenada's material to the Committee on the Peaceful Uses of Outer Space for possible consideration in 1979.
• DOCUMENTED It created nothing. A "decision" is the General Assembly's weakest instrument — below a resolution, adopted without a recorded vote, carrying no obligation, no budget line, no mandate and no secretariat. Decision 33/426 established no office, appointed no official, and allocated no funds. It is routinely cited on the internet as "the UN's UFO resolution"; it is a decision, not a resolution, and its operative verb is "invites."
• DOCUMENTED The initiative died with its sponsor's government. On 13 March 1979, while Gairy was abroad — accounts say at the UN for further discussions on the subject — the New Jewel Movement under Maurice Bishop seized power in Grenada in a largely bloodless coup. Gairy never returned to office. With no other Member State willing to carry it, the item lapsed. COPUOS did not take it up substantively.
• DOCUMENTED There is no standing UN body today, and the reasons are structural. No state has proposed a successor mandate. UN bodies require a sponsoring state coalition, a budget appropriation and a home committee; UAP has no natural home — COPUOS handles outer space law and debris, ICAO handles aviation safety incidents, and neither has jurisdiction over "unknown objects in national airspace," which is a sovereignty and defence matter states guard closely. The one thing every state agrees on is that it does not want an international body examining its own airspace sensor data.
• UNSUPPORTED Claims of secret UN briefings, an existing UN UFO office, or the "UN Office for Outer Space Affairs alien liaison." A recurring hoax cycle — including a widely circulated 2010 story that Malaysian astrophysicist Mazlan Othman of UNOOSA had been appointed "Earth's ambassador to aliens," which Othman and UNOOSA publicly denied at the time. No document supports any of it.

• DOCUMENTED Fewer than a dozen of roughly 195 states have ever run a named public UAP channel. The list below is close to exhaustive. Everywhere else, an unidentified object in national airspace is handled — if at all — inside an air-defence identification process that publishes nothing.

• DOCUMENTED The consequence: global UAP data is a map of disclosure law, not of the sky. The countries that dominate every dataset — the US, UK, France, Brazil, Chile, Canada, Australia — are the countries with freedom-of-information statutes, declassification schedules or public archives. The apparent geographic clustering of UAP reports in North America, Western Europe and parts of South America is an artefact of who publishes.
• DOCUMENTED There is also no common definition, taxonomy or reporting form. France's GEIPAN uses a four-class scheme (A/B/C/D by explanation confidence); the US AARO uses its own categories; China uses "unidentified air conditions"; Australia used "unusual aerial sightings." No two national datasets are directly comparable, and none use a shared case-numbering system. Cross-national statistical claims about UAP trends are therefore built on incommensurable data.
• UNSUPPORTED Claims of a coordinated international UFO secrecy agreement. Variously described as a NATO protocol, a "UN treaty," or a Five Eyes arrangement. No text has ever been produced. The evidence is equally consistent — and far better explained — by the mundane alternative: most states simply never built a mechanism, and the ones that did guard sensor performance data because it reveals radar and IR capability, not because of what was detected.
