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.
Football-shaped UAP captured by advanced US military sensor platform in the Indo-Pacific. Object caused temporary sensor interference upon approach and displayed acceleration beyond Mach 5.
USS Nimitz Carrier Strike Group radar operators tracked an unknown object for two weeks before F/A-18 pilots were tasked to intercept. Commander Fravor observed a white 40-foot oblong object with no wings, propulsion, or exhaust hovering over a roiling sea disturbance before it accelerated away instantaneously. FLIR footage declassified by DoD in 2020.
Australian pilot Frederick Valentich radioed Melbourne Air Traffic Control to report a metallic craft with a green light orbiting his Cessna over Bass Strait. His last transmission described the object hovering above him and his engine beginning to malfunction. A final metallic scraping sound was recorded on the ATC tape — then silence. Neither Valentich nor his aircraft was ever found. The Australian Department of Transport investigation found no explanation.
An Australian television news crew aboard an Argosy cargo aircraft filmed approximately 30 minutes of footage of luminous objects over the Kaikoura coast of New Zealand. The footage was analyzed by the Royal Australian Air Force and Eastman Kodak, who confirmed the objects were real and not lens flares. New Zealand's Civil Aviation Division investigated and could not identify the objects.
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.
Anglican priest Rev. William Gill and 38 witnesses at a mission station in Papua New Guinea observed a disc-shaped craft with apparent occupants over two consecutive nights. The British Colonial Government filed an official report. Gill and three other witnesses waved at the figures on the craft; the figures appeared to wave back. The case remains unexplained in all official assessments.
Approximately 200 school students and teachers observed a disc-shaped craft descend, land briefly in a field adjacent to Westall High School, and then depart at high speed. Five smaller craft were also observed. The Royal Australian Air Force (RAAF) responded and reportedly confiscated grass samples and directed witnesses not to speak about the incident. The Australian Dept of Air classified the investigation. Students and teachers report being told to sign confidentiality agreements.
Multiple unidentified craft were observed and tracked on radar over the top-secret Woomera Rocket Range in South Australia between 1954 and 1956. The range housed joint Australian-British-American missile testing programs. Australian Dept of Air SECRET reports, later declassified, document RAAF radar tracking of objects at extreme altitudes performing maneuvers beyond any known aircraft. British Ministry of Supply personnel and US Army observers filed corroborating reports.
A Chilean Navy helicopter crew filmed an unidentified object on infrared for approximately 9 minutes. The Chilean government's official UAP investigation body CEFAA analyzed the footage for two years and concluded the object was 'a highly accelerated, solid, hot object' that could not be identified as any known aircraft. The footage was released publicly by CEFAA in January 2017 with a formal statement confirming the object is unexplained.
A disc-shaped craft was photographed by commercial diver and photographer Almiro Baraúna from the deck of the Brazilian Navy vessel Almirante Saldanha off Trindade Island. Approximately 40 Navy personnel witnessed the object. The Brazilian Navy officially released the photographs and Brazilian President Kubitschek confirmed their authenticity. The photographs were technically analyzed for decades and are among the most extensively examined UAP images in the official record.
In 2010, the New Zealand Defence Force released 2,000 pages of classified UFO files spanning 1952–1984. The release was the largest official New Zealand government UAP document release. The files included RNZAF pilot reports, radar tracking data, witness statements, and official investigations. Many cases remained officially unexplained. The files are accessible through Archives New Zealand.
The Brazilian Air Force deployed a secret investigation team (Operation Saucer / Operação Prato) to northern Brazil following mass civilian sightings of craft that injured residents with light beams. The Brazilian Air Force classified the investigation SECRET. Colonel Uyrangê Hollanda led the team. The operation documented hundreds of incidents. Hollanda's interview before his death confirmed the Air Force considered the craft real and unexplained.
The USS Kitty Hawk carrier strike group operating in the Pacific documented UAP encounters in late 2003 that preceded the famous 2004 Nimitz encounters by less than a year. VF-154 Black Knights F-14D crews reported encounters with unidentified objects that disappeared on radar approach. The incidents were reported through standard military channels. AARO incorporated the Kitty Hawk strike group UAP reports in its historical database.
The USS Princeton guided-missile cruiser, acting as the air warfare command ship for the Nimitz Carrier Strike Group, tracked anomalous radar contacts for approximately two weeks before the now-famous Tic-Tac visual encounter on November 14, 2004. Senior Chief Kevin Day documented the tracks showing objects dropping from 80,000 feet to sea level in approximately 0.78 seconds — an acceleration that would require forces of thousands of G's. Day later testified publicly about the radar data.
Beginning in late January 1996, a wave of UAP sightings swept the Central Coast of New South Wales around Gosford, Australia. New South Wales Police officers filed multiple formal incident reports. Naval Air Station Nowra radar operators reported anomalous contacts. The Australian Dept of Defence reviewed the reports. Local police took hundreds of public reports. The wave is documented in official NSW Police records and referenced in Australian parliamentary questions.
A classified UK Ministry of Defence report documented a Royal Navy encounter with an unidentified object in the South Atlantic that appeared to enter and exit the ocean at speed. The report was prepared for the UK Defence Intelligence Staff. The incident was classified SECRET. Portions of the report were later disclosed through the UK National Archives under the 30-year declassification rule.
A large disc-shaped object was tracked over the Mururoa nuclear test atoll by multiple intelligence assets during a period of French nuclear testing. US monitoring stations and Australian signals intelligence confirmed the contact. The object appeared to enter the restricted airspace coinciding with scheduled test detonations.
Multiple UAP contacts were tracked by the USS Omaha Carrier Strike Group during July 4th independence holiday operations. Spherical objects swarmed ship formations and one was tracked diving into the ocean. P-8 Poseidon crews were tasked with submarine search of the descent area.
In one of the most-witnessed close-range encounters in history, over 300 students and teachers at multiple Victorian schools observed a disc-shaped craft perform maneuvers at low altitude. Australian military subsequently investigated but classified their findings.
An Australian television film crew aboard a cargo aircraft captured sixteen minutes of 16mm color film of unidentified lights off the New Zealand coast. The footage was analyzed by military, civilian, and scientific experts worldwide and remains one of the most thoroughly studied UAP films.
The world's first nuclear carrier USS Enterprise experienced a close-range UAP encounter in the Western Pacific. Multiple F-4 Phantom crew members made visual and radar contact. The encounter occurred during combat operations and was classified under special compartment procedures given the nuclear propulsion sensitivity.
A Soviet submarine commander logged a detailed encounter with an unidentified submerged object that matched his vessel's speed and maneuvers for 12 minutes before surfacing and departing as a disc. The report was obtained by US intelligence and entered into USO/UAP files maintained by the Office of Naval Intelligence.
Personnel at Argentine, British and Chilean scientific bases on Deception Island simultaneously observed a disc-shaped craft for 30 minutes in July 1965. All three nations' Antarctic Treaty representatives filed official diplomatic cables describing the encounter. The incident was coordinated under the Antarctic Treaty framework.
20-year-old pilot Frederick Valentich radioed Melbourne Flight Service describing a craft with a green light orbiting his Cessna 182. His last transmission described his engine failing. Neither he nor his aircraft was ever found. Australian authorities conducted the largest air-sea search in Victoria's history.
The complete Nimitz CSG encounter involved not just the Tic-Tac but multiple objects over several days, transmedium behavior, and USS Princeton tracking objects descending from 80,000 feet to sea level. Commander David Fravor's intercept was one engagement in a multi-day event involving dozens of witnesses.
The USS Omaha transmedium footage shows a spherical object descending from 21,000 feet and entering the ocean at high speed with no splash. Authenticated by the Pentagon in 2021. This is the clearest filmed transmedium UAP entry in the authenticated military record.
Two separate airline crews simultaneously reported a fast-moving luminous object at high altitude over the Pacific near Hawaii. FAA Honolulu Center confirmed the reports were simultaneous and independent. The incident was included in FAA Aviation Safety Reporting System records and subsequently cited in Congressional UAP briefings.
RAAF Pearce radar and Perth airport simultaneously tracked a formation of objects over Western Australia. Merchant ship crews off the coast also filed reports. The RAAF's investigation produced one of Australia's most detailed classified military UAP records from the 1950s.
Just months after Mount Pinatubo's eruption closed Clark Air Base, residual USAF personnel and Philippine Air Force units observed a sustained UAP encounter over the Philippine Sea. The encounter was classified under post-Clark transition protocols and routed to Pacific Air Forces.
The Knowles family's ninety-minute encounter on the Nullarbor Plain included a craft landing on their car roof, lifting the vehicle, and filling it with a gray powder and foul odor. Police, customs officers, and two separate truck drivers independently confirmed the physical evidence. Australian media gave it extensive coverage.
USS Carl Vinson's airwing encountered orbs during Indian Ocean operations nine months before the famous Nimitz events. The encounters are considered part of the same pattern of Navy carrier strike group UAP activity documented across Pacific and Indian Ocean theaters in 2004.
Australian TV journalist Quentin Fogarty and film crew aboard a New Zealand cargo aircraft filmed luminous orbs pacing the aircraft over the Kaikoura coastline. Wellington Air Traffic Control confirmed radar returns. The footage was broadcast globally and analyzed by physicists. New Zealand Department of Defence investigation concluded the objects were genuine unidentified phenomena.
A disc hovered over the Royal Australian Navy communications facility near Perth and HMAS Stirling before departing at extreme speed. RAAF Pearce radar tracked the contact. Perth Police received civilian reports. The Royal Australian Navy filed a confidential report to the RAAF Air Defence command. Australian Department of Air investigation noted the incident's proximity to sensitive naval communications infrastructure.
More than 300 students and teachers at two Melbourne schools simultaneously observed a silver-grey disc land in an adjacent paddock and depart at high speed. RAAF and Victoria Police arrived within hours. Students reported being warned by school staff not to speak about the incident. Physical traces including a flattened circular area were found at the landing site. Australia's largest documented multi-witness school UAP encounter.
RAAF aircraft were vectored to an unidentified contact tracked simultaneously by Hobart approach control and RAAF Edinburgh Air Defence radar over the Bass Strait. The contact performed extreme maneuvers. Australian Department of Air added the report to its classified UAP file. The Bass Strait is one of the most frequently reported Australian UAP corridors, with multiple documented encounters across decades.
Pilot Frederick Valentich reported a large unidentified craft with four bright lights orbiting his Cessna 182 over Bass Strait in a live radio transmission to Melbourne Flight Service. His final transmission was preceded by a metallic scraping sound. Valentich and his aircraft were never found. RAAF investigation could not explain the encounter or the disappearance. One of the most studied aviation UAP disappearances in history.
Anglican missionary Reverend William Gill and 37 mission staff and village witnesses observed a large disc with a superstructure and humanoid figures on its upper deck for multiple hours over multiple nights at Boianai Anglican Mission, Papua New Guinea. Gill and the figures appeared to wave at each other. Project Blue Book received the report via US Embassy. Gill's detailed written accounts on the night of the encounter are preserved.
Farmer George Pedley observed a disc rise from a swamp lagoon in Far North Queensland, Australia, leaving a circular area of flattened and woven reeds 30 feet in diameter. The 'saucer nest' was investigated by Queensland Police and Queensland Department of Primary Industries. Multiple additional nests were subsequently found. The Tully saucer nest is considered the first documented crop circle incident associated with a UAP observation.
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 Australia's most significant UAP events, involving over 200 school students and multiple teachers who witnessed a disc-shaped craft land or hover in a paddock adjacent to Westall High School in Melbourne. Students who ran to the paddock saw the craft before it departed at high speed, leaving a circular pressed-grass impression. Several students reported the craft was subsequently approached by uniformed men who confiscated film and instructed witnesses to say nothing. The case remained actively suppressed for decades.
