Over 13,500 witnesses reported a large triangular object with bright lights traversing Belgium over 18 months. Belgian Air Force F-16s achieved radar lock on the object twice; it accelerated from 280 mph to 1,100 mph in 2 seconds and descended from 10,000 ft to 1,000 ft in 5 seconds. The Belgian government publicly acknowledged and investigated the sightings. U.S. Embassy Brussels diplomatic cables are included in the 2026 archive release.
A V-shaped formation of soft blue-green lights traveled silently over Lubbock, Texas on multiple occasions in late 1951, witnessed initially by four Texas Tech professors and subsequently photographed by 18-year-old Carl Hart Jr. The photographs were analyzed by Project Blue Book and the Air Force never produced a definitive explanation. Blue Book's final report lists it as 'unknown.'
Multiple witnesses observed 4 amber-lit objects fly in formation over Shag Harbour, Nova Scotia, before one entered the ocean. RCMP officers confirmed the sighting. Canadian military divers searched but found no wreckage. Canadian government opened an official investigation, classifying it as 'unknown' — making it one of the few government-acknowledged transmedium UAP events in the historical record. U.S. SOSUS and naval records are in the 2026 archive release.
Newly declassified Armed Forces Special Weapons Program records document 209 separate UAP sightings at Sandia Base, New Mexico — the nation's primary nuclear weapons facility — between 1948 and 1950. Witnesses, primarily military personnel, described orbs that performed high-speed maneuvers and, in several cases, appeared to explode. The proximity to classified nuclear infrastructure was assessed as a national security concern. The files are part of the May 2026 Pentagon archive release.
A senior U.S. intelligence officer flying aboard a military helicopter over a western U.S. military test range in 2025 encountered what they described as 'countless orange orbs swarming in all directions.'

A large triangular craft was observed causing power anomalies in the Northeast Utilities power grid in New Haven County. Police officers from multiple agencies observed the craft. Northeast Utilities engineers who responded to the grid anomalies independently observed the same craft. The FAA received reports from commercial pilots in the area. The power grid anomaly was documented in utility records.
Multiple law enforcement agencies observed a formation of orbs performing maneuvers over the National Mall in Washington DC — the same restricted airspace over the US Capitol, White House, and national monuments. Metropolitan Police, US Capitol Police, and Secret Service personnel all filed reports. Reagan National Airport ATC received reports from pilots. The proximity to National Special Security Event airspace gave the encounter an extremely high security significance.
Indian Coast Guard vessels patrolling the Gujarat coast reported multiple luminous orbs performing formation maneuvers near the coast for 35 minutes. The encounter coincided with a significant increase in unidentified aerial object reports from the Indian western coastal zone in 2013. Indian Navy Western Command received the report. The Gujarat encounters were part of the broader pattern of Indian UAP sightings that prompted the DRDO Ladakh monitoring program.
USS Philippine Sea airwing reported a formation of discs performing maneuvers off the Virginia Capes. The encounter was tracked by Atlantic Fleet radar. Multiple Navy aircraft crews from different squadrons independently observed the same formation. The encounter was forwarded to Project Grudge, which classified the case. The Philippine Sea case preceded the more famous 1952 Washington wave by one year and was among the cases that helped build the intelligence case demanding serious government investigation.
Navajo Nation tribal police and reservation residents reported an extensive wave of triangular craft observations across the Navajo Reservation spanning Arizona, New Mexico, and Utah in 1994. Navajo Nation tribal police filed formal reports. Navajo Nation Council members raised the encounters with state law enforcement. The FBI Phoenix field office received reports. The geographic concentration across the sacred Navajo territory gave the wave cultural as well as security significance.
A formation of five luminous orbs was tracked by Soviet military personnel and Volga fleet vessels near the birthplace of Lenin in Ulyanovsk for 28 minutes. The proximity to a Soviet strategic military region gave the encounter political sensitivity. The Soviet Academy of Sciences UAP Commission added the Ulyanovsk case to its Volga Region priority database. US SIGINT later detected anomalous Soviet military communications traffic corresponding to this date.
The Bass Strait between Victoria and Tasmania experienced a documented wave of UAP encounters in 1978 involving multiple RAAF aircraft, civil aviation crews, and Bass Strait ferry crews. The Australian Department of Air tracked the wave and issued a classified summary. The 1978 Bass Strait wave preceded and set the context for the October 1978 Valentich disappearance, and researchers have argued the full extent of the wave made the disappearance more credible.
One of the largest mass UAP observation events in US history, occurring over the Hudson Valley of New York and Connecticut from 1983 to 1987. More than 5000 individuals reported observing a massive boomerang or triangular formation of lights — often described as a city-block-sized craft moving silently — performing low-altitude, slow-speed maneuvers. Police, doctors, engineers, and IBM computer scientists were among witnesses. The New York Power Authority reported it approaching the Indian Point nuclear plant.
The June 24, 1947 sighting by private pilot Kenneth Arnold of nine crescent-shaped objects near Mount Rainier, Washington, is considered the origin point of the modern UFO era. Arnold's description — objects moving 'like a saucer skipped across water' — gave rise to the term 'flying saucer.' Arnold was a highly experienced pilot with excellent aviation credentials. His report triggered thousands of similar sightings worldwide and led directly to the US Army Air Force's Project Sign, the first government UAP investigation.
The earliest known gun-camera-quality motion picture of UAP, filmed by Great Falls baseball team manager Nicholas Mariana. The 16mm color Kodachrome footage shows two bright objects performing a slow sweep across the Montana sky. The US Air Force analyzed the film twice — the second analysis noted that 35 frames showing the objects most clearly had been removed from the returned film. The Air Force classified the remaining footage as 'jets with sun glint' — a conclusion later contradicted by trajectory analysis.
Hundreds of Allied bomber and fighter aircrew reported luminous orbs and spheres — nicknamed 'foo fighters' — that shadowed their aircraft over Europe and the Pacific from late 1944 through 1945. The phenomena were reported by B-17 and B-29 crews, P-47 and P-51 pilots, and confirmed by multiple crews on the same mission. Both Allied and German/Japanese air forces reported similar phenomena — a fact only recognized after the war when German and Japanese records were examined. No conventional explanation was found.
Three days before the Kenneth Arnold sighting, harbor patrolman Harold Dahl reported observing six doughnut-shaped craft, one of which appeared troubled and dropped hot metal slag onto his patrol boat, injuring his son and killing his dog. Dahl recovered slag fragments. A military intelligence officer sent to investigate was killed with his aircraft when it crashed after the investigation. The FBI examined the case. It was later alleged that Dahl had fabricated the account, but the slag fragments were genuine and analyzed.
Japan Airlines cargo flight 1628, en route from Paris to Tokyo via Anchorage, tracked three unidentified objects for 50 minutes over Alaska. The objects were confirmed on FAA air traffic control radar and observed visually by all three crew members. The largest object was estimated to be larger than two aircraft carriers. The FAA conducted an official investigation. Captain Terauchi held a press conference and the case became one of the most extensively covered aviation UAP events of the decade.
A large V-formation of amber lights performed a slow pass over the New York Harbor area on July 14, 2001, observed by hundreds of New Jersey and New York residents. Multiple video recordings captured the formation from different vantage points across the Hudson River area. Police departments in multiple NJ municipalities received calls. FAA radar at Newark Airport showed no transponder returns for the objects. The event occurred just 58 days before the September 11, 2001 attacks, in restricted airspace.
One of the largest mass UAP observations in US history, with over 500 residents of Farmington, New Mexico observing a massive formation of disc-shaped objects on three consecutive days in March 1950. The objects were described as moving at extreme speed, sometimes in formation and sometimes individually. The Farmington Daily Times ran a front-page headline. The proximity to the Los Alamos National Laboratory and the four corners nuclear testing area attracted significant investigative interest.
The March 13, 1997 Phoenix Lights event involved two distinct phenomena over Arizona: a massive V-shaped formation of lights that traversed the state from north to south — observed by tens of thousands over several hours — and a separate cluster of stationary lights over Phoenix itself. Then-Governor Fife Symington initially ridiculed the events, but years later admitted he personally witnessed the V-formation and described it as otherworldly. Numerous military and law enforcement witnesses have corroborated the formation.
