In fiscal year 2022–2023, Japan's Air Self-Defense Force scrambled fighters against unidentified aerial phenomena 53 times, more than quadruple the prior year's total and the highest figure since JASDF record-keeping began. In September 2020, Defense Minister Taro Kono had already issued standing orders requiring SDF personnel to photograph and document any unidentified object and to immediately halt training exercises if one is encountered.

In August 2023, the U.S. Defense Department's new UAP transparency website formally designated Japan as a global hotspot for unidentified aerial phenomena, based on trend analysis of sightings logged between 1996 and 2023. Japan's parliament responded by forming an 80-member bipartisan research group in 2024, including former defense ministers, to lead the country's first systematic institutional investigation.

On September 14, 2020, Japanese Defence Minister Tarō Kōno announced that the Japan Self-Defence Forces had adopted a formal protocol requiring SDF pilots to photograph, record, and report any encounter with unidentified aerial phenomena. The directive was Japan's first standing order on UAP encounters and was modelled in part on the U.S. Navy's 2019 reporting guidelines.

On November 9, 2018, commercial pilots flying for British Airways, Virgin Atlantic, and a Norwegian carrier reported very bright, fast-moving objects passing their aircraft off the southwest coast of Ireland. Shannon Air Traffic Control confirmed nothing showed on military radar, and the Irish Aviation Authority opened a formal investigation under its confidential occurrence reporting process.

On November 11, 2014, two Chilean Navy officers in an Airbus Cougar AS-532 helicopter filmed an unidentified object for nine minutes using a Wescam MX-15 HD infrared camera west of Santiago. The object was invisible to the naked eye and emitted two separate thermal plumes. Neither on-board radar nor two ground radar stations detected it. CEFAA's two-year investigation concluded unanimously: cause unknown.

In April 2013, four technicians at the remote Collahuasi copper mine in Chile's Atacama highlands, at over 14,000 feet elevation, observed a brilliant disc-shaped object approach slowly, hover for more than an hour, then depart eastward. One technician photographed it with a Samsung S860 camera. CEFAA's subsequent analysis ruled out meteorological phenomena, aircraft, weather balloons, and drones.

On October 23, 2013, the Peruvian Air Force (Fuerza Aérea del Perú) relaunched its Department of Investigation of Anomalous Aerial Phenomena under the new acronym DIFAA, after the original OIFAA office created in 2001 had gone dormant for several years. The department's mandate was framed by its leadership as grounded in the Peruvian Constitution's assignment of sovereign aerospace responsibility to the FAP.

Between August and October 2012, an Indo-Tibetan Border Police unit near Pangong Lake, Ladakh, logged over 100 sightings of luminous yellowish spheres rising from the Chinese side of the line and traversing the sky for three to five hours. A mobile radar unit and spectrum analyzer deployed to the site detected no metallic signature and no electromagnetic emissions. Indian astronomical observers confirmed the objects were 'non-celestial.'

In May 2011, Argentina's Air Force officially launched the Commission for the Investigation of Aerospace Phenomena (CEFAe), headquartered at FAA headquarters in Buenos Aires. Its first public report, released in 2015, analyzed multiple documented cases from Argentine airspace. Argentina thereby joined Chile, Uruguay, Peru, and Brazil as Latin American nations with active, institutionalized military UFO investigation bodies.

At an air show over El Bosque Air Force Base in Santiago on November 5, 2010, an object moving too fast to be seen by spectators or pilots passed near three separate jet formations. Halcones, F-5s, and F-16s. Seven video recordings from different angles captured it. CEFAA photogrammetric analysis by Air Force and Army technicians estimated its velocity at 4,000 to 6,000 miles per hour.

On July 7, 2010, an unidentified aerial object forced Hangzhou Xiaoshan International Airport to halt all departures; 18 flights were grounded or diverted to Ningbo and Wuxi. A flight crew first detected the object at 8:40 p.m. during approach. Chinese authorities concluded it 'may have been an aircraft, possibly military,' but never issued a definitive identification.

In 2009, Brazil became the first country to institutionalize ongoing military UFO disclosure, releasing over 2,200 pages of formerly classified documents to the Arquivo Nacional and issuing Ordinance 551/GC3 requiring all armed forces branches to forward UAP reports to the national archive annually. The files span 1952 to 2015 and include radar data, photographs, and pilot reports from the FAB's SIOANI investigation system.

Between 2008 and 2013 the UK Ministry of Defence transferred nearly 60,000 pages of UFO investigation files to the National Archives, making them freely downloadable. The releases covered every recorded sighting from 1953 to 2009, more than 12,000 reports, and included the complete case files for Rendlesham, Cosford, and West Freugh. The MoD formally closed its UFO desk in November 2009.

On April 23, 2007, Aurigny Airlines captain Ray Bowyer, en route from Southampton to Alderney over the Channel Islands, observed two stationary bright yellow objects stretching what he estimated at roughly a mile in width at 40 miles' distance. A second aircraft from Blue Islands Airlines independently reported the same objects from a different approach vector. Jersey Airport radar recorded faint primary contacts for 55 minutes.

On October 19, 1998, four Chinese military radar stations in Hebei province simultaneously tracked an unidentified object hovering above a PLA aviation training base near Changzhou. A Jianjiao-6 interceptor pursued the object for nearly an hour; when the jet closed to 4,000 meters, the craft shot upward at a speed that outpaced the fighter entirely. At least 140 ground observers reported a mushroom-shaped craft with rotating multicolored lights.

In 1997, twenty years after commanding Operação Prato, Captain Uyrangê Hollanda gave a filmed interview to Brazilian UFO researchers Ademar Gevaerd and Marco Petit, stating that his team had directly observed the objects, photographed them close-up, and believed them to be intelligently controlled. He described the classification order and his own growing conviction that the phenomenon was real. Three months later he was found dead.

On March 13, 1997, thousands of Arizona and Nevada residents observed two separate events over Phoenix: a silent V-shaped formation of lights traversing the state at low altitude, and a stationary arc of brilliantly lit objects visible for 106 minutes; then-Governor Fife Symington mocked witnesses publicly but stated in 2007 that he personally witnessed 'something otherworldly.'

Phoenix, Arizona

On January 20, 1996, three young women in Varginha, Minas Gerais, encountered a crouching creature with red eyes and a large domed head in a vacant lot. Within hours, military police and firefighters moved through the city; multiple witnesses reported seeing beings transported under military guard to local hospitals. Military police officer Marco Eli Chereze died twenty-six days later under disputed circumstances.

On January 6, 1995, a British Airways Boeing 737 approaching Manchester Airport at 13,000 feet over the Pennines had a near-miss with an unlit wedge-shaped object that flashed silently past the cockpit. Captain Roger Wills and First Officer Mark Stuart filed reports with the Civil Aviation Authority. After a year-long inquiry the CAA's Joint Air Miss Working Group found no likely explanation.

Spain began declassifying Air Force UFO files in 1992 and completed a staged public release through 1997, depositing physical copies in the Central Library of the Air Force. The Manises 1979 incident file, declassified August 1994, was among the most significant, including the Mirage F1 pilot's debriefing, radar logs from two separate tracking stations, and the airline crew's signed statements.
