Incidents where UAP maintained a stationary position with no visible means of propulsion or lift — defying known aerodynamics.
Materials recovered near Roswell, NM. A hexagonal disc approximately 20 feet in diameter was documented, suspended from a balloon. Modern re-analysis notes 'composition inconsistent with known terrestrial alloys'.
Astronaut Frank Borman reported a 'bogey' keeping pace with Gemini 7 in orbit. Audio recording included in the current indexed archive 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.
Photograph shows three dots in triangular formation in the lunar sky. Harrison Schmitt reported a flash north of Grimaldi crater. NASA's assessment: 'no consensus about the nature'. Photographs not included in original public mission archives.
Federal agents witnessed orange orbs described as resembling 'the Eye of Sauron without a pupil', emitting smaller red orbs in groups of 2–4. Rated 'among the most compelling cases in AARO's holdings.'
NATO pilot reported a 'triangular and metallic UAP' at 25,000 ft over the Mediterranean. Object hovered motionless for 4 minutes then accelerated to beyond sensor range instantaneously.
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.
FBI Photo B20: an infrared still of an unidentified craft hovering at under 1,000 ft for 45 minutes. Object defied wind conditions and maintained perfect stationary position with no discernible propulsion.
Recurring UAP activity reported near nuclear installations in Eastern Europe. Luminous spheres that neutralized sensor systems upon approach. Recurring pattern documented across multiple facilities.
A massive V-shaped formation of lights traversed Arizona from north to south on March 13, 1997, witnessed by an estimated 10,000 people including the sitting governor. FAA radar records and military communications included in the 2026 archive release remain unexplained for the formation event.
A metallic disc-shaped object was observed hovering silently over Gate C17 at O'Hare International Airport by over a dozen United Airlines employees and flight crew. The FAA initially denied radar contact; a Freedom of Information Act release revealed internal FAA discussion of the event. The object punched a clear circular hole through the overcast cloud layer upon departure.
An F/A-18 Super Hornet ATFLIR pod captured a disc-shaped object visibly rotating against the direction of wind at 25,000 feet. The object moved into the prevailing wind and appeared to rotate continuously with no visible means of propulsion. DoD officially released the FLIR footage in 2020; AARO lists it 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 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.
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.
Socorro police officer Lonnie Zamora observed a white oval craft with red insignia resting on legs in an arroyo, attended by two figures in white. He observed the craft take off with a roaring flame, become silent after 20 feet, and depart at high speed. Physical evidence — burned vegetation, soil compression, metal scrapings — was immediately confirmed by State Police and Army investigators. Project Blue Book listed this as 'unknown.'
Over the course of two hours on November 2, 1957, nine independent witnesses in and around Levelland, Texas reported their vehicles' engines dying and headlights extinguishing when a large, glowing egg-shaped object appeared near or over their vehicles. Engines and electrical systems restarted immediately when the object departed. Six separate highway incidents in different locations within a 10-mile radius all occurred within the same two-hour window.
In March 1967, a red-orange glowing orb was observed hovering over Launch Control Facility Echo at Malmstrom AFB. Within minutes, all ten Minuteman ICBMs at Echo went into 'No-Go' status — the missiles were inoperable for nuclear launch. A similar event was reported separately at Oscar Flight the same morning. The event has never received an unclassified technical explanation.
A retired engineer observed a disc-shaped object land in his terraced garden in southern France. Physical trace evidence collected by French national police (Gendarmerie) was subsequently analyzed by GEPAN — the French government's official UAP investigation body — and found to include ground compression, scorched vegetation, and unusual biochemical changes in plant matter at the landing site. GEPAN's 1983 report remains one of the most rigorous official government UAP physical evidence analyses ever published.
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.' The objects were oval-shaped with orange and white centres. At one point a group of the orbs assembled into a triangular formation before vanishing. The encounter lasted over an hour. The witness account is included in the May 2026 Pentagon 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.
USAF Captain Thomas Mantell died when his F-51 Mustang disintegrated at 30,000 ft while pursuing a large, metallic, stationary object over Fort Knox. Godman Field tower personnel and multiple pilots observed the object. Project Sign classified the incident SECRET. No official explanation has been accepted.
Nick Mariana captured approximately 16 seconds of 16mm color footage showing two bright disc-shaped objects flying in formation over Great Falls, Montana. USAF Project Blue Book analyzed the film and initially attributed the objects to F-94 jets; subsequent independent analysis found the objects' luminosity and flight path inconsistent with that explanation.
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.
Two Portage County Sheriff's deputies pursued a luminous disc-shaped object for 85 miles across Ohio into Pennsylvania, joined mid-pursuit by officers from multiple jurisdictions. Project Blue Book attributed the object to Venus — an explanation the officers publicly disputed, triggering congressional scrutiny of the Blue Book program.
A B-52H crew and ground radar simultaneously tracked an unidentified object over Minot AFB's nuclear missile field. The object descended to 200 feet, disrupted radio communications, and was observed by base security near missile launch facilities. Project Blue Book closed the case as 'insufficient data' — later declassified Blue Book files show the radar returns were confirmed as real targets.
An Army Reserve UH-1 helicopter crew of four had a near-collision with a large grey metallic object over Mansfield, Ohio. The object stopped the helicopter's controlled descent and the aircraft inexplicably climbed 2,000 feet with no crew input. The incident is regarded as one of the most credible military UAP cases in the official record due to the four-person trained military crew and corroborating ground witnesses.
A large acorn-shaped metallic object with a raised band of unknown symbols around its base crashed into woods near Kecksburg, Pennsylvania. The Army cordoned off the area within hours and reportedly recovered a large object on a flatbed truck. NASA reopened the case in 2003 following a lawsuit and could not produce the original investigation file.
Three civilians suffered documented acute radiation injuries after a close encounter with a large diamond-shaped, flame-emitting craft escorted by 23 military Chinook helicopters on a Texas highway. The witnesses sued the U.S. government for damages; the case was dismissed because the government denied ownership of either the craft or the Chinook escort.
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.
A multi-year wave of sightings of a massive V-shaped or boomerang-shaped craft with white lights produced over 7,000 documented witness reports across New York and Connecticut. FAA radar at Stewart Airport confirmed unidentified targets. The object was observed hovering silently over the Indian Point Nuclear Power Plant.
USS Omaha combat information center footage captured a spherical object hovering over the ship and entering the ocean without a splash. The Navy sent a submarine to search for wreckage and found nothing. The declassified footage was released by the DoD in 2021 as part of the first official UAP video release and is among the cases referenced in the 2021 UAP Task Force preliminary assessment.
USS Russell combat information center captured night-vision footage showing triangular or pyramid-shaped UAPs flying in formation over the ship at approximately 700 feet. The DoD authenticated the footage in 2021. The pyramid appearance is attributed in some Navy analysis to a bokeh artifact from the night-vision optics — but the objects themselves remain unidentified.
Two hikers photographed a large diamond-shaped craft hovering at low altitude near Calvine, Scotland. The UK Ministry of Defence classified the photographs SECRET and kept them for 30 years before release in 2022. Defence Intelligence Staff analysts assessed the object as between 25–100 metres in diameter and of 'unknown origin.'
