On September 19, 1976, two Imperial Iranian Air Force F-4 Phantom jets scrambled to intercept a luminous object over Tehran. Both aircraft suffered complete electronics and weapons failures at close range; a declassified Defense Intelligence Agency cable rated it an 'outstanding' case and circulated findings to the White House, Joint Chiefs, NSA, and CIA.

On September 25, 1975, a Uruguayan Air Force FH-227 flight from Asunción to Montevideo at 14,000 feet encountered a yellowish luminous object that matched the aircraft's speed and altitude for an extended period after the pilot activated his landing light and received an immediate reaction from the unknown object. Uruguay's CRIDOVNI, established by presidential decree in 1979, formally investigated.

On February 23, 1975, two seven-year-old boys in Kōfu, Japan, reported watching a domed silver disc approximately 15 feet wide land in a vineyard behind their housing estate. Physical traces found at the site included overturned concrete posts, soil impressions, and what one investigating teacher described as radioactivity traces. The Japanese Civil Aviation Bureau attributed the sighting to a YS-11 propeller plane, a conclusion that drew immediate criticism for not addressing the physical ground evidence.

On September 4, 1971, a National Geographic Institute of Costa Rica aerial survey aircraft photographed a sharp, metallic disc over Lago Cote at 10,000 feet while the automatic mapping camera cycled every 13 seconds. The object appeared in one frame only. Analysts Dr. Richard Haines and Dr. Jacques Vallée examined the original negative and concluded the image was not a double exposure or fabrication.

Throughout spring and summer 1968, U.S. Marine Corps forward observers, Navy patrol crews, and intelligence officers reported slow-moving unidentified lights hovering near the Vietnamese Demilitarized Zone and over the sea toward Tiger Island. In June 1968, USS PCF-19 was destroyed and HMAS Hobart was hit by missiles in the same operational zone on a night when 30 anomalous lights had been reported; a U.S. Navy Board of Inquiry confirmed no hostile aircraft was ever identified in the area.

On August 29, 1967, a 13-year-old boy and his 9-year-old sister reported four small black beings rising into a hovering disc in a field near Cussac, France. The local gendarmerie investigated the same day, noting a sulfur odor and scorched grass at the site.

Cussac, France

On April 6, 1966, more than 200 students and teachers at two Melbourne schools watched a silver, domed disc descend into a field near Westall High School. The object left flattened grass circles, and witnesses were later warned by uniformed officials not to speak about what they had seen.

On July 1, 1965, lavender farmer Maurice Masse encountered an egg-shaped craft on six legs in his field near Valensole, France, accompanied by two small humanoid figures. The following day, gendarmes photographed and measured a cross-shaped ground impression 1.2 meters across. Lavender did not regrow on the spot until 1975.

Valensole, France

At approximately 2:00 a.m. on September 3, 1965, 18-year-old Norman Muscarello and two Exeter, New Hampshire police officers independently observed a large, silent disc with five sequentially flashing red lights hovering 100 feet above a field before departing at high speed; the Air Force later wrote that it could not identify the object.

Exeter, New Hampshire

On January 16, 1958, at least 47 crew members and civilian researchers aboard the Brazilian Navy ship Almirante Saldanha watched a Saturn-shaped object circle Trindade Island. Civilian photographer Almiro Barauna captured four frames with his Rolleiflex before the object reversed course and departed. President Kubitschek personally authorized release of the prints to the press.

On April 4, 1957, three separate radar stations operating a bombing range at RAF West Freugh in Wigtownshire, Scotland, tracked a large stationary object that rose vertically to 60,000 feet with no forward motion before accelerating toward the Isle of Man at high speed. A second formation of four smaller objects was simultaneously tracked by a second station.

On the night of November 2–3, 1957, at least seven separate motorists on two different roads near Levelland, Texas, reported that their engines and headlights failed simultaneously as an egg-shaped luminous object passed overhead, then restarted when it departed, with over 15 calls made to the local police station within two hours.

Levelland, Texas

On the night of August 13-14, 1956, ground radar at RAF Bentwaters and RAF Lakenheath, airborne radar aboard a USAF bomber, and visual observers all tracked unidentified objects moving at extreme speeds over East Anglia. Two RAF de Havilland Venom jets were scrambled; one pilot reported the target maneuvering behind his aircraft and shadowing him for ten minutes.

On August 31, 1954, Royal Australian Navy pilot Lt. Shamus O'Farrell observed two brilliant, fast-moving objects pass his Sea Fury fighter over Nowra, NSW. Radar operator Petty Officer Keith Jessop at HMAS Albatross confirmed two independent returns near the aircraft. The Directorate of Naval Intelligence called O'Farrell 'an entirely credible witness.'

Nowra, New South Wales, Australia

On August 23, 1953, Tom Drury, Deputy Director of Civil Aviation for Papua New Guinea, filmed a silver dart-shaped object emerging from a cloud over Port Moresby on 8mm color film. The footage was sent to the United States for analysis; when returned, the best frames had been removed. A 1966 RAAF summary could not account for the missing frames.

Port Moresby, Papua New Guinea

On January 29, 1952, crews of two separate B-29 Superfortresses operating over North Korea, one over Wonsan, one over Sunchon, independently reported orange globe-shaped lights pacing their aircraft for up to five minutes. Far East Air Forces commander Lt. Gen. Otto P. Weyland publicly acknowledged an ongoing investigation, and the incident was logged in Project Blue Book as among the earliest multi-crew, multi-aircraft Korean War-era UAP cases.

On the nights of July 19–20 and July 26–27, 1952, radar operators at Washington National Airport and Andrews Air Force Base simultaneously tracked unidentified objects over the restricted airspace above the U.S. capital; intercepting F-94 jets found the objects only to watch them vanish from radar, then reappear when the fighters departed.

Washington, D.C.

In May 1951, near Chorwon, South Korea, PFC Francis P. Wall and his Army company reported a pulsating orange object descending through active artillery fire undamaged. Wall fired his M1 rifle at it and heard metallic ricochets. Three days later the entire company was evacuated with elevated white blood cell counts, rapid weight loss, and severe dysentery, physiological effects that baffled attending Army physicians.

Chorwon, South Korea

Between August and September 1951, three Texas Tech professors observed formations of 20–30 lights passing silently over Lubbock, Texas, in under 30 seconds; freshman Carl Hart Jr. photographed five separate passes on August 30, producing images published in Life magazine that Wright-Patterson Air Force Base analysts could neither authenticate nor disprove.

Lubbock, Texas

On January 7, 1948, Kentucky Air National Guard Captain Thomas Mantell died when his P-51 Mustang crashed near Franklin, Kentucky, after he climbed in pursuit of a large, luminous object tracked by multiple control towers and reported by civilian witnesses; he was the first U.S. military pilot to die during a UFO pursuit.

Franklin, Kentucky

On July 24, 1948, Eastern Airlines captains Clarence Chiles and John Whitted reported that a wingless, cigar-shaped craft roughly 100 feet long passed within 700 feet of their DC-3 near Montgomery, Alabama, at 5,000 feet altitude, with an exhaust flame visible from the rear, a sighting that convinced Project Sign analysts UFOs were interplanetary.

Near Montgomery, Alabama

On June 24, 1947, private pilot Kenneth Arnold reported nine crescent-shaped objects flying at roughly 1,200 mph near Mount Rainier, Washington, a credible sighting that introduced the term 'flying saucer' into public discourse and triggered the first formal USAF investigation program.

Mount Rainier, Washington

In July 1947, the Roswell Army Air Field public affairs office issued a press release announcing recovery of a 'flying disc' from a ranch near Roswell, New Mexico; the statement was retracted within hours in favor of a weather balloon explanation, and a 1995 GAO audit found that outgoing Roswell base message traffic from the period had been destroyed.

Roswell, New Mexico

Between May and December 1946, the Swedish Defence Staff logged approximately 2,000 sightings of cigar-shaped objects (the so-called 'ghost rockets', spökraketer) over Scandinavia. On October 10, 1946, the Defence Staff publicly stated that some 200 of the observations could not be explained as natural phenomena, Swedish aircraft, or imagination.

During World War II, Allied servicemen stationed at Wycliffe Well in Australia's Northern Territory documented repeated UFO sightings in a handwritten journal kept at the local camp. The volume of recorded incidents prompted a formal Royal Australian Air Force investigation.

Wycliffe Well, Northern Territory, Australia

On February 24–25, 1942, the U.S. Army fired more than 1,400 anti-aircraft shells over Los Angeles after radar operators and ground observers reported unidentified objects; five civilians died in the chaos, and no enemy aircraft or debris was ever recovered.

Los Angeles, California

On November 13, 2024, journalist Michael Shellenberger published a report attributed to an anonymous Pentagon source describing an alleged Special Access Program code-named 'Immaculate Constellation' purportedly tracking and recovering UAP.

United States

On June 5, 2023 The Debrief published a story by Leslie Kean and Ralph Blumenthal reporting that intelligence officials had told Congress the U.S. had retrieved craft of non-human origin, citing former intelligence officer David Grusch as the named source.
