20242024 U.S. air base drone incursions in the United KingdomThe 2024 U.S. air base drone incursions in the United Kingdom were one of the clearest military-site drone cases in the late-2024 UAP-adjacent wave. Unlike many public sightings that collapsed into aircraft or star misidentifications, this event was anchored by official confirmation: small unmanned aerial systems were seen near and over U.S.-used RAF bases in England, including RAF Lakenheath, RAF Mildenhall, RAF Feltwell and RAF Fairford. The unresolved question is not whether every light in the sky was exotic. It is who operated the drones, why they appeared around sensitive bases, and what the episode revealed about modern counter-drone vulnerability.United KingdomGrade B / DISPUTED 20242024 U.S. Drone SightingsIn late 2024, reports of drones and unusual lights across New Jersey and the northeastern United States prompted federal investigations, flight restrictions, and public concern. Authorities said many reports matched lawful drones, aircraft, stars, or planets, while confirmed drone activity near sensitive sites remained a real airspace-security issue. This dossier separates verified events from viral claims.United StatesGrade B / DISPUTED 20232023 high-altitude object eventsThe 2023 high-altitude object events were a short but intense North American airspace crisis that followed the Chinese surveillance balloon incident. In less than two weeks, U.S. and Canadian authorities tracked and shot down several objects over Alaska, Yukon and Lake Huron. The public mystery was dramatic, but the best-supported reading is more practical than exotic: radar sensitivity, aviation safety concerns, balloons, possible research or commercial platforms, and uncertainty over debris recovery combined into a modern UAP-adjacent security episode.United StatesGrade B / EXPLAINED 2023Eglin AFB UAP case resolutionOn 26 January 2023, a military pilot operating in the Eglin Air Force Base training range off Florida reported four potential UAP as a flight-safety and range-incursion concern. AARO later resolved the case as very likely a lighter-than-air object, such as a large commercial lighting balloon, with moderate confidence and no confirmed anomalous behavior. The case is valuable because it shows how a modern official UAP report can move from uncertainty to a documented conventional assessment.United StatesGrade A / EXPLAINED 2020Los Angeles jetpack man reportsPilots reported a human-like object near Los Angeles airspace, prompting FAA and FBI attention.United StatesGrade C / DISPUTED 2020Mage UFO reportsReports and videos from Mage spread widely online with claims of crashes or military activity.BrazilGrade C / DISPUTED 2019USS Omaha sphere videoThe USS Omaha case centers on a July 2019 infrared-display video showing a round target over the ocean and an operator calling 'splash' as it disappears; the footage was taken by Navy personnel, but the public clip does not prove that an object entered the water.United StatesGrade B / UNRESOLVED 2016Mosul orbThe Mosul orb is a military image said to have been recorded over Iraq in 2016 and later presented in public UAP discussion; the image is real as a published record, but its range, motion, full sequence and object identity are not available in a complete public case file.IraqGrade C / UNRESOLVED 2015Gimbal UAP videoA U.S. Navy infrared video known as Gimbal shows an object apparently rotating during a training flight.United StatesGrade A / UNRESOLVED 2015GoFast UAP videoGoFast is a January 2015 U.S. Navy infrared video whose apparent near-surface high speed became a central UAP claim; AARO's 2025 analysis assessed with high confidence that the object showed no anomalous performance.United StatesGrade A / DISPUTED 2013Aguadilla UFO incidentA thermal camera video near Aguadilla airport became a widely debated UAP clip.Puerto RicoGrade C / DISPUTED 2011Jerusalem Dome of the Rock UFO videosThe Jerusalem Dome of the Rock videos were a viral 2011 online UFO claim showing a light above the shrine. The case is valuable mainly as a digital-era video-hoax and verification lesson.IsraelGrade D / DISPUTED 20102010 Xiaoshan Airport UFO IncidentOn 7 July 2010, Hangzhou Xiaoshan International Airport halted or diverted flights after an unidentified object was reported nearby. The operational disruption is documented in contemporary reporting, but the object's identity, the official investigative record, and the connection of widely circulated photographs to the airport event remain uncertain. This dossier separates the closure, image claims, official limits, and conventional explanations.ChinaGrade C / DISPUTED 2010El Bosque Air Base UFO videoObjects filmed during an air show near El Bosque Air Base were discussed in Chilean UAP contexts.ChileGrade C / DISPUTED 2009Morristown UFO hoaxRed lights over New Jersey were later admitted to be a staged hoax using balloons and flares.United StatesGrade A / EXPLAINED 2009Norwegian spiral anomalyA spectacular spiral light over Norway was widely reported before being explained as a failed Russian missile test.NorwayGrade A / EXPLAINED 2008Stephenville UFO sightingsResidents reported large silent objects near Stephenville, later tied by some to military training flights.United StatesGrade B / DISPUTED 2008Wales UFO helicopter incidentA police helicopter crew reportedly took evasive action after seeing an unidentified object.United KingdomGrade C / DISPUTED 2007Dudley DoritoA series of black triangle sightings in the West Midlands became known as the Dudley Dorito.United KingdomGrade C / DISPUTED 2007Guernsey UFO sightingPilots and passengers reported large yellow objects near Guernsey.United KingdomGrade B / UNRESOLVED 2007Kumburgaz UFO videosThe Kumburgaz videos are a series of Turkish night recordings showing distant lights or shapes over multiple dates. They are important as a video-analysis case, but their evidentiary value depends on distance, optics, and source context.TurkeyGrade C / DISPUTED 2006Chicago O'Hare UFO sightingAirport employees reported a disc-like object over O'Hare that appeared to punch through clouds.United StatesGrade B / UNRESOLVED 2004Mexican Air Force UFO affairInfrared footage from a Mexican Air Force aircraft was released as a UFO case and later debated.MexicoGrade B / EXPLAINED 2004Nimitz Tic Tac UFO encounterThe Nimitz Tic Tac encounter is one of the strongest modern military UAP cases because it combines trained aviator testimony, shipboard radar claims, infrared video, and later official acknowledgement that the video records unidentified aerial phenomena.United StatesGrade A / UNRESOLVED 1997Phoenix LightsThe Phoenix Lights became one of the best-known mass-sighting cases of the 1990s because many people across Arizona reported a large formation or lights, while later video of separate lights was linked to military flares.United StatesGrade B / EXPLAINED 1996Varginha UFO incidentThe Varginha incident centers on reports from January 1996 that residents saw strange creatures and unusual activity around the city of Varginha. It became a national UFO story because the claims expanded from a street encounter into rumors of military transport, hospital involvement, animal deaths, and alleged recovered beings.BrazilGrade B / DISPUTED 1996Yukon giant UFOWitnesses in Yukon reported a large object crossing the sky in 1996.CanadaGrade C / DISPUTED 1995Bariloche UFO incidentA pilot approaching Bariloche reported a bright object during a widely reported Argentine incident.ArgentinaGrade B / DISPUTED 1995South African Airways UFO reportAircrew reports from South African aviation contexts appear in UFO case lists.South AfricaGrade C / DISPUTED 1994Ariel School encounterStudents at Ariel School reported seeing a craft and beings near the school grounds.ZimbabweGrade B / DISPUTED 1993Cosford UFO incidentA wave of triangular-object reports across Britain included sightings near RAF Cosford.United KingdomGrade B / DISPUTED 1990Calvine UFO photographThe Calvine photograph is a disputed Scottish UFO image reportedly taken in 1990 and later associated with Ministry of Defence interest. It is important because it combines a striking image, delayed public access, and unresolved provenance questions.United KingdomGrade C / DISPUTED 1990Greifswald lightsLarge lights filmed near Greifswald became a notable European UFO video case.GermanyGrade B / EXPLAINED 1989Belgian UFO Wave (1989-1990)The Belgian UFO wave began in November 1989 with reports of large, quiet triangular light formations and later included police observations, radar claims and an F-16 response; the witness record is substantial, but no single technical interpretation resolves the whole wave.BelgiumGrade B / DISPUTED 1989Voronezh UFO incidentReports from children and locals about a landed craft and beings became international news.RussiaGrade C / DISPUTED 1987Gulf Breeze UFO incidentThe Gulf Breeze case is a late-1980s Florida photo controversy centered on Ed Walters and a series of alleged UFO images. It is useful for studying how spectacular photographs can divide witnesses, investigators, and local media.United StatesGrade C / DISPUTED 1986Brazil Night of the UFOsBrazilian fighters were scrambled after radar and visual reports of unidentified objects.BrazilGrade B / UNRESOLVED 1986Height 611 UFO incidentWitnesses reported a spherical object crashing into Height 611 near Dalnegorsk.RussiaGrade C / DISPUTED 1986Japan Air Lines Flight 1628A cargo crew reported large unidentified objects while flying over Alaska.United StatesGrade B / UNRESOLVED 1986Japan Airlines Flight 1628 UFO incidentOn November 17, 1986, the crew of Japan Air Lines cargo flight 1628 reported unusual lights and a large dark object while flying over eastern Alaska toward Anchorage. The case is historically important because it generated pilot testimony, air-traffic communications, radar discussion and a large FAA file later found in the National Archives, while skeptical reviews have proposed celestial, radar and cloud-related explanations.United StatesGrade B / DISPUTED 1983Hudson Valley UFO waveThousands reported large V-shaped or boomerang-like lights over the Hudson Valley region.United StatesGrade B / DISPUTED 19821982 Laxou L'Amarante UFO caseAt about 12:35 on 21 October 1982, a biologist in Laxou, France, reported an oval object hovering roughly one metre above his garden for about twenty minutes. GEPAN investigated within days and sampled amaranth plants that the witness said had changed after the event. Its Technical Note 17 preserves the investigation but does not provide a conclusive causal finding.FranceGrade B / DISPUTED 1981Trans-en-Provence UFO caseOn 8 January 1981, farmer Renato Nicolai reported seeing a small object land briefly near his property in Trans-en-Provence, France, leaving physical marks. The case is frequently cited because French official investigators examined the site and associated biological or soil effects.FranceGrade B / UNRESOLVED 1980Cash-Landrum incidentThe Cash-Landrum incident is a disputed Texas close-encounter case in which witnesses reported a bright object, helicopters, and later health effects. It is important because it connects UFO testimony with injury claims and unsuccessful legal action.United StatesGrade C / DISPUTED 1980Halt memoThe Halt memorandum is a key document associated with the Rendlesham Forest incident.United KingdomGrade B / DISPUTED 1980La Joya UFO incidentA Peruvian pilot reportedly fired on a balloon-like unidentified object without effect.PeruGrade B / UNRESOLVED 1980Rendlesham Forest incidentRendlesham Forest is often called Britain's Roswell because it involves U.S. Air Force personnel, multiple nights of reports, alleged physical traces, audio claims, and a formal memorandum.United KingdomGrade B / DISPUTED 1979Manises UFO incidentA commercial flight diverted to Manises after the crew reported red lights approaching the aircraft.SpainGrade B / DISPUTED 1979Robert Taylor incidentForestry worker Robert Taylor reported an encounter with a dome-like object and small spheres.United KingdomGrade C / DISPUTED 1979Val Johnson incidentSheriff's deputy Val Johnson reported an encounter with a bright light that damaged his patrol car.United StatesGrade C / DISPUTED 1978Clarenville UFO sightingA police officer and other witnesses reported and photographed lights near Clarenville.CanadaGrade B / DISPUTED 1978Emilcin abductionFarmer Jan Wolski reported an abduction-like encounter near Emilcin.PolandGrade C / DISPUTED 1978Frederick Valentich disappearancePilot Frederick Valentich disappeared after radioing about an unusual aircraft above him.AustraliaGrade B / UNRESOLVED 1978Kaikoura lightsAircrews and a television crew reported and filmed unusual lights near Kaikoura.New ZealandGrade B / DISPUTED 1978Zanfretta abductionItalian security guard Pier Fortunato Zanfretta reported repeated encounters with beings.ItalyGrade C / DISPUTED 1977Amarante UFO photographsPhotographs from Amarante are cited in Portuguese UFO discussions.PortugalGrade C / DISPUTED 1977Broad Haven UFO sightingsChildren and locals around Broad Haven reported craft and beings during a Welsh UFO wave.United KingdomGrade C / DISPUTED 1977Operation Saucer: Brazil's Colares UFO InvestigationOperation Saucer (Operacao Prato) was a 1977 Brazilian Air Force investigation into reports of unusual lights and alleged injuries around Colares, Para. Surviving records confirm an official inquiry, witness interviews, field observations, and photographs, but the public file is incomplete and does not identify an extraordinary craft. This dossier keeps military records, testimony, and later folklore separate.BrazilGrade B / DISPUTED 1977Petrozavodsk phenomenonA luminous phenomenon over Petrozavodsk became a major Soviet-era UFO report.RussiaGrade B / EXPLAINED 19761976 Talavera Air Base UFO incidentIn the early hours of 12 November 1976, guards at Talavera la Real Air Base near Badajoz reported an unusual encounter while on duty. Spain's Ministry of Defence later released a 28-page file documenting the report and the resulting military inquiry. The file establishes that an investigation occurred, but it does not establish an extraterrestrial or supernatural cause.SpainGrade B / DISPUTED 1976Canary Islands UFO incidentLarge luminous phenomena were reported over the Canary Islands and later linked to missile activity.SpainGrade B / DISPUTED 1976Cannon AFB UFO reportThe Cannon AFB report is a New Mexico airbase case most often encountered through secondary investigation archives and witness retellings. It has search value because of the location and military setting, but the public primary record is thinner than stronger Blue Book-era cases.United StatesGrade C / INSUFFICIENT DATA 1976Tehran UFO incidentIranian fighter pilots were scrambled after reports of a bright object over Tehran.IranGrade B / UNRESOLVED 19751975 Loring AFB UFO incursionsOn 27 and 28 October 1975, personnel at Loring Air Force Base in Maine reported unidentified low-level aerial activity near the weapons storage area. Security, tower and radar accounts prompted alerts and an attempted response. The incident belongs to a broader two-week series of 1975 reports at U.S. strategic bases.United StatesGrade B / UNRESOLVED 1975Travis Walton abductionThe Travis Walton case is one of the best-known abduction claims, involving a logging crew in Arizona, a missing-person search, and Walton's later account of a craft encounter. It is influential but remains disputed.United StatesGrade C / DISPUTED 1975Wurtsmith AFB UFO incidentIn late October 1975, Wurtsmith Air Force Base in Michigan reported low-flying unknown aircraft or helicopter activity around the base. The case is useful because a declassified military message and mainstream reporting anchor what could otherwise be treated as rumor.United StatesGrade B / DISPUTED 1974Berwyn Mountain incidentReports of lights and an impact-like event in Wales became associated with UFO crash theories.United KingdomGrade C / EXPLAINED 1973Coyne helicopter incidentAn Army Reserve helicopter crew reported a close encounter with a bright object over Ohio.United StatesGrade B / UNRESOLVED 1973Falkville metal manA police chief photographed a metallic-looking figure during a reported UFO-related encounter.United StatesGrade D / DISPUTED 1973Pascagoula abductionThe Pascagoula case centers on Charles Hickson and Calvin Parker, who said they were taken aboard a craft while fishing in Mississippi in 1973. It remains a major abduction narrative because of prompt police involvement and later audio-recording interest.United StatesGrade C / DISPUTED 1971Lake Cote Costa Rica UAP photographOn 4 September 1971, an automated aerial-survey camera operated for Costa Rica's National Geographic Institute photographed Lake Cote and the surrounding terrain during work connected to a hydroelectric project near Arenal. One frame later drew attention because a dark, disc-like form appeared over the lake area. The case remains disputed, but it belongs in the archive because the image has a documented survey context, a named photographer, a public-domain scan and clear limits on what a single photograph can prove.Costa RicaGrade B / DISPUTED 1971USS Trepang UFO photographsImages sometimes attributed to a U.S. submarine patrol circulate as a contested naval UFO photo case.Arctic OceanGrade C / DISPUTED 19691969 Pori Finnish Air Force UFO sightingOn 12 April 1969, Finnish Air Force personnel at Pori Airport reported seven yellow, round or disc-like objects during a Fouga Magister training flight. Pilots Tarmo Tukeva and Jouko Kuronen became the best-known named witnesses. Finnish broadcaster Yle later preserved their accounts and archival discussion of the event.FinlandGrade B / UNRESOLVED 1968Minot Air Force Base UFO caseMilitary personnel and a B-52 crew reported unusual aerial activity near Minot AFB.United StatesGrade B / UNRESOLVED 19671967 Duhamel UFO landing marksOn 5 August 1967, farmer Edgar Schielke found four circular or elliptical tracks in pasture near Duhamel, Alberta, after heavy rain. No one reported seeing a craft make the marks. A Defence Research Establishment Suffield scientist inspected the site on 11 August and produced Memorandum 49/67, which documented the traces but did not determine their cause.CanadaGrade B / INSUFFICIENT DATA 19671967 Falcon Lake IncidentOn 20 May 1967, Stefan Michalak reported a close encounter near Falcon Lake followed by burns and site-related material; the medical and archival trail makes it more documented than many encounter stories, but there was no independent witness to the object.CanadaGrade B / DISPUTED 1967Cussac UFO encounterTwo children reported seeing a spherical object and small beings near Cussac.FranceGrade C / DISPUTED 1967Malmstrom missile UFO reportsFormer missile personnel later connected UFO reports with missile shutdown events at Malmstrom.United StatesGrade B / DISPUTED 1967Shag Harbour UFO incidentWitnesses reported lights descending into the water near Shag Harbour, prompting search activity.CanadaGrade B / UNRESOLVED 19661966 Westall UFO IncidentOn 6 April 1966, students and teachers near Westall High School in Melbourne reported a low-flying object that appeared to descend near school grounds. The large witness pool makes Westall a major Australian UFO case, but surviving records do not establish what was seen. This dossier compares testimony, later interviews, official uncertainty, and conventional explanations.AustraliaGrade B / UNRESOLVED 1966Lead Masks caseTwo men were found dead wearing lead masks; later speculation linked the case to UFO and occult themes.BrazilGrade C / UNRESOLVED 1966Portage County UFO chaseOn April 17, 1966, Ohio police officers reported chasing a luminous saucer-shaped object from Portage County into Pennsylvania. The Air Force treated the case as conventional, but later criticism from UFO investigators and scientific consultants kept it in the disputed case file.United StatesGrade B / DISPUTED 1966Tully saucer nestA farmer reported seeing a craft rise from a swamp, leaving a circular flattened reed formation.AustraliaGrade C / DISPUTED 19651965 Valensole UFO IncidentFarmer Maurice Masse reported a landed object and small beings near Valensole.FranceGrade C / DISPUTED 1965Exeter UFO incidentThe Exeter UFO incident is a 1965 New Hampshire case in which Norman Muscarello and local police officers reported bright red flashing lights near rural Exeter and Kensington. It became notable because the main witness account was quickly joined by police observation and later Air Force review.United StatesGrade B / DISPUTED 1965Kecksburg UFO IncidentResidents near Kecksburg, Pennsylvania reported a fireball and a possible crash landing in 1965, after which the story grew into one of America's most debated alleged UFO recovery cases.United StatesGrade C / DISPUTED 1965Warminster ThingWarminster became a British UFO hotspot after reports of strange sounds and lights.United KingdomGrade C / DISPUTED 1964Socorro / Lonnie Zamora UFO IncidentNew Mexico police officer Lonnie Zamora reported seeing an egg-shaped craft and two small figures near Socorro in 1964, making the case one of Project Blue Book's most investigated close-range reports.United StatesGrade B / UNRESOLVED 1960Red Bluff Project Blue Book UFO caseOn the night of August 13, 1960, California Highway Patrol officers Charles A. Carson and Stanley Scott reported a silent, illuminated object near Red Bluff and Corning. The case is valuable because it combines trained public-safety witnesses, local follow-up and a surviving Project Blue Book file, while still leaving important gaps about radar, astronomy and the Air Force's final reasoning.United StatesGrade B / UNRESOLVED 1959Father Gill Papua New Guinea sightingAnglican priest William Gill and others reported a large object with figures near Boianai.Papua New GuineaGrade B / UNRESOLVED 1958Trindade Island UFO photographsPhotographs allegedly taken from a Brazilian Navy vessel became an important Latin American UFO case.BrazilGrade B / DISPUTED 19571957 Milton Torres UFO interceptOn 20 May 1957, U.S. Air Force pilot Milton Torres was scrambled from RAF Manston in an F-86D after ground controllers reported a very large radar target over eastern England. Torres later said he was ordered to prepare a full rocket salvo, but the target disappeared from radar before he obtained a visual contact or fired.United KingdomGrade B / UNRESOLVED 1957Fort Itaipu UFO incidentThe Fort Itaipu story describes Brazilian sentries allegedly burned after a close approach by a luminous object near the coast in 1957. It is famous in South American UFO literature, but later researchers have emphasized that public military records confirming the full story are hard to locate.BrazilGrade C / INSUFFICIENT DATA 1957Kirtland AFB UFO sightingOn 4 November 1957, two Civil Aeronautics Administration tower controllers at Kirtland Air Force Base in Albuquerque reported a maneuvering light and a dark, egg-shaped object near the airfield, followed by radar discussion. The Air Force investigated the report under Project Blue Book and classified the likely explanation as a possible aircraft. The case is useful because it combines trained aviation observers, radar context, a conventional official explanation and later criticism of that explanation.United StatesGrade B / DISPUTED 1957Levelland UFO caseMotorists reported bright objects and temporary vehicle failures near Levelland.United StatesGrade B / DISPUTED 1957RB-47 radar-visual UFO incidentIn September 1957, a U.S. Air Force RB-47 reconnaissance aircraft carrying electronic countermeasures equipment reported a prolonged encounter across the Gulf Coast, Texas and Oklahoma. The case is notable because it combines cockpit visual reports, airborne electronic detections and ground-radar context, while still remaining unresolved in the public record.United StatesGrade B / UNRESOLVED 1956Lakenheath-Bentwaters radar-visual incidentOn the night of August 13-14, 1956, radar and visual reports from RAF Bentwaters and RAF Lakenheath in Suffolk described fast, luminous targets that appeared over U.S.-used air bases in eastern England. The case remains important because it entered Project Blue Book and the Condon Report, where investigators treated it as a difficult radar-visual file rather than a simple light-in-the-sky story.United KingdomGrade B / DISPUTED 1955Kelly-Hopkinsville encounterThe Kelly-Hopkinsville encounter is a famous Kentucky close-encounter claim in which a family reported small beings around a farmhouse. It is valuable as a witness-and-police-response case, but the extraordinary portion remains disputed.United StatesGrade C / DISPUTED 19541954 BOAC Labrador UFO sightingDuring the night of 29-30 June 1954, a BOAC Boeing 377 Stratocruiser flying from New York toward London via Goose Bay reported a large dark or luminous formation accompanied by six smaller objects near the Labrador-Quebec route. Captain James Howard, other crew and passengers watched for roughly eighteen to twenty-two minutes before the objects faded from view.CanadaGrade B / UNRESOLVED 1954Florence stadium UFO sightingOn 27 October 1954, a football match in Florence reportedly paused as thousands of spectators looked at objects in the sky and filament-like material later called angel hair. The case has strong cultural visibility and media documentation but remains disputed because spider-silk explanations are plausible.ItalyGrade C / DISPUTED 1954Quarouble Marius Dewilde UFO encounterOn 10 September 1954, railway worker Marius Dewilde reported seeing small figures and a dark object near tracks at Quarouble in northern France. The case became a centerpiece of the French 1954 wave because it included a named witness, official attention and alleged physical traces.FranceGrade C / DISPUTED 1953Ellsworth AFB UFO reportA Cold War air base report involving unidentified aerial activity entered UFO case catalogs.United StatesGrade C / DISPUTED 1953Kinross incidentAn interceptor disappeared over Lake Superior after being vectored toward an unidentified radar target.United StatesGrade B / UNRESOLVED 19521952 RAF Topcliffe UFO sightingOn 19 September 1952, RAF Shackleton aircrew at Topcliffe reported a silver circular object near a Meteor jet during the NATO exercise Mainbrace. Flight Lieutenant John Kilburn provided the best-known statement. The report was sent rapidly into Air Ministry intelligence channels and survives in the UK National Archives record AIR 20/7390.United KingdomGrade B / UNRESOLVED 1952Flatwoods monsterThe Flatwoods Monster case began after a bright object crossed the West Virginia sky in September 1952 and local residents reported a frightening figure near a wooded hill. The archive treats it as a culturally important but likely explainable close-encounter story.United StatesGrade C / EXPLAINED 1952Haneda AFB radar-visual UFO caseIn August 1952, personnel at Haneda Air Force Base near Tokyo reported a bright object and radar contact in an episode later cited in Air Force UFO literature. The case is significant because it combines military airfield observers, radar tracking and an international setting outside the continental United States.JapanGrade B / UNRESOLVED 1952Nash-Fortenberry UFO sightingTwo Pan American pilots reported a formation of bright objects over Chesapeake Bay.United StatesGrade B / UNRESOLVED 1952Oloron-Sainte-Marie UFO sightingOn 17 October 1952, residents of Oloron-Sainte-Marie in France reported a cigar-shaped object, smaller objects and falling filament-like material. The case is a classic angel-hair report, but natural explanations involving spider silk and atmospheric perception are central to any careful reading.FranceGrade C / DISPUTED 1952Tremonton UFO filmOn 2 July 1952, Navy Warrant Officer Delbert Newhouse filmed a group of bright objects near Tremonton, Utah. The footage became one of the better-known Project Blue Book film cases because it was reviewed by military analysts and later discussed in the Robertson Panel context.United StatesGrade B / DISPUTED 1952Washington D.C. UFO incidentRadar returns and visual reports over Washington, D.C. triggered military attention across two weekends.United StatesGrade B / DISPUTED 1951Fort Monmouth UFO caseRadar operators and pilots reported fast unidentified targets near Fort Monmouth.United StatesGrade B / UNRESOLVED 1951Lubbock LightsWitnesses in Lubbock reported V-shaped formations of lights, with photographs later published widely.United StatesGrade B / DISPUTED 19501950 McMinnville UFO PhotographsPaul Trent's two May 1950 photographs are among the best-known early UFO images; they preserve a real photographic record, but uncertain range and scale prevent the pictures alone from distinguishing a distant object from a small nearby model.United StatesGrade B / DISPUTED 1950Farmington UFO ArmadaBetween March 15 and 18, 1950, newspapers in Farmington, New Mexico, reported that numerous residents had watched formations of bright or silvery objects crossing the daytime sky. The event survives through contemporary press coverage and later witness interviews, but no verified physical evidence or definitive official resolution is public.United StatesGrade B / DISPUTED 1950Mariana UFO filmNicholas Mariana filmed bright objects over Great Falls in one of the early motion-picture UFO cases.United StatesGrade B / DISPUTED 1949Clyde Tombaugh UFO sightingAstronomer Clyde Tombaugh, best known for discovering Pluto, reported seeing unusual geometric lights near Las Cruces, New Mexico, in 1949. The case is notable because of the witness's astronomical background, but it remains a testimony-based report without public instrument data.United StatesGrade C / DISPUTED 19481948 Mantell UFO IncidentPilot Thomas Mantell died while pursuing an unidentified object later associated with a high-altitude balloon explanation.United StatesGrade B / EXPLAINED 1948Aztec UFO incidentA crash-retrieval story alleging a recovered craft near Aztec became part of UFO lore.United StatesGrade D / DISPUTED 1948Chiles-Whitted UFO encounterTwo Eastern Air Lines pilots reported a glowing cigar-shaped object passing their aircraft.United StatesGrade B / UNRESOLVED 1948Gorman dogfightPilot George Gorman reported maneuvering with a light-like object over Fargo.United StatesGrade B / UNRESOLVED 1947Kenneth Arnold sightingPilot Kenneth Arnold reported seeing fast crescent-like objects near Mount Rainier, helping popularize the phrase flying saucer.United StatesGrade B / UNRESOLVED 1947Maury Island incidentA controversial pre-Roswell story involving alleged debris from unidentified craft over Puget Sound.United StatesGrade D / DISPUTED 1947Roswell incidentRoswell is the most famous alleged UFO crash story, but its archive value depends on separating the July 1947 debris recovery from later alien-body and crash-retrieval narratives.United StatesGrade C / EXPLAINED 1947West Rindge UFO debris caseDeclassified records and a new NHPR report describe a 1947 West Rindge, New Hampshire case involving alleged metallic debris, a local witness trail and later official attention during the early flying-disc era.United StatesGrade C / DISPUTED 1946Angelholm UFO memorialSwedish entrepreneur Gosta Carlsson said he experienced a UFO encounter later commemorated by a monument.SwedenGrade C / DISPUTED 1946Ghost rocketsA wave of rocket-like aerial reports spread across Scandinavia after World War II.SwedenGrade B / UNRESOLVED 1944Foo fightersAllied aircrews reported unusual lights or objects near aircraft during World War II.EuropeGrade B / UNRESOLVED 1942Battle of Los Angeles UFO caseIn the early hours of February 25, 1942, anti-aircraft batteries around Los Angeles fired into the night sky after radar and air-raid warnings suggested a possible hostile target. No enemy aircraft was found, and the event is now widely treated as a wartime false alarm that later entered UFO culture through photographs, headlines and retellings.United StatesGrade B / EXPLAINED 1908Tunguska UFO theoriesThe Tunguska explosion is scientifically explained as an airburst, but has long attracted UFO speculation.RussiaGrade C / EXPLAINED 1803Utsuro-bune legendA Japanese legend describes a hollow vessel and strange woman arriving on shore, later interpreted by some as UFO-like.JapanGrade D / DISPUTED 15611561 Nuremberg celestial phenomenonThe 1561 Nuremberg celestial phenomenon is a pre-modern broadsheet report later reinterpreted by UFO writers. It is valuable as historical sky-phenomena material, not as modern sensor evidence.GermanyGrade D / DISPUTED
