Photographic, USA

A cigar-shaped 'object' in a winter 1870 stereograph of Mount Washington, New Hampshire, was once called the earliest photograph of a UFO; it is now generally traced to a cropped scale ruler in a frost-formation photo.

Photographic, Mexico

Other, USA

A June 1884 Nebraska State Journal story of a crashed cylindrical 'celestial visitor' on the Nebraska plains was a newspaper fabrication, admitted as a hoax in 1927, and is among the earliest American UFO-type stories still cited by ufologists.

Sighting, Australia

A recurring, unexplained light reported across Queensland's Channel Country since the early 1890s, most famously near the ruined Min Min Hotel, and widely attributed to a superior mirage of distant headlights or campfires.

Mass sighting, USA

A five-month wave of reported 'mystery airships' swept the western and then central United States from November 1896 to April 1897, generating thousands of newspaper reports and a mix of genuine misidentifications, hoaxes, and press-driven excitement.

Crash retrieval, United States

During the Great Airship Wave of 1896–1897, a cigar-shaped craft allegedly crashed into a windmill in Aurora, Texas, and townspeople reportedly buried the non-human pilot in the local cemetery — a story that has been debated for over a century.

Other, Russia

A massive explosion near the Podkamennaya Tunguska River in Siberia on June 30, 1908, remains the largest impact event in recorded history and a subject of UFO speculation.

Mass sighting, New Zealand

Mass UFO wave across New Zealand in winter 1909 featuring cigar-shaped and boat-shaped craft with occupants, generating hundreds of reports and consistent eyewitness descriptions.

Sighting, USA

Mass sighting, South Africa

Between 11 August and 9 September 1914, thousands of South Africans reported a night-flying monoplane, or its headlights, in a wave that was widely attributed to German aircraft but was never identified and is now studied as a case of collective belief.

Mass sighting, Portugal

On October 13, 1917, an estimated 30,000–70,000 people witnessed a spinning, multicolored luminous disk perform aerial maneuvers near Fátima, Portugal. The phenomenon, claimed as proof of a Marian apparition, later became a case study in mass UFO sightings.

Sighting, China

During the Roerich expedition across Central Asia, the Russian painter-philosopher Nicholas Roerich recorded in his diary an oval object in the sky that his party watched through field glasses before it vanished; the single, uncorroborated entry later became a frequently cited pre-Roswell 'flying saucer' reference.

Other, USA

Five U.S. Navy TBM Avenger bombers on a navigation training flight vanished over the Atlantic on 5 December 1945; a Mariner sent to search for them was also lost, and the case became the foundation of the Bermuda Triangle legend and a cultural touchstone for UFO-adjacent speculation.

Contact, Sweden

Railway worker Gösta Carlsson said he saw a disc-shaped craft land in a forest near Ängelholm in May 1946 and met its crew; the claim, first made public in 1971 and memorialised in 1972, rests on his testimony alone.

Crash retrieval, United States

In July 1947, debris from an unidentified object was recovered from a ranch near Roswell, New Mexico; the U.S. Army initially announced the capture of a 'flying disc' before retracting the claim, launching the most enduring and consequential UFO controversy in history.

Mass sighting, USA

On 8 July 1947, several officers and engineers at the Army Air Field at Muroc, California, reported silver disc-like and oval objects over the base; sworn statements were taken and the case went to the Fourth Air Force, which left it pending.

On August 18, 1947, the captain and co-pilot of a United Air Lines flight near Boise reported two silver, disc-shaped objects passing about 2,000 feet below their aircraft at an estimated speed near 960 mph, one of several airline reports in the Boise area that summer.

Crash retrieval, USA

The debris that rancher W. W. 'Mac' Brazel found near Corona, New Mexico, in June–July 1947 is the same material that sparked the Roswell story; the 1994 Air Force review tied it to a classified Project Mogul balloon, but Stanton Friedman and Don Berliner later argued in Crash at Corona (1992) that it marked a separate alien craft crash.

Crash retrieval, USA

A widely publicized 1949–50 claim that a 100-foot flying saucer and 16 humanoid bodies were recovered near Aztec, New Mexico in 1948 — a story that made a bestseller of journalist Frank Scully's book before being exposed as a fraud built by two con men to sell fake oil-detecting devices.

Other, USA

Project Grudge was the second U.S. Air Force UFO study, run from late 1948 to 1952 between Project Sign and Project Blue Book. Its August 1949 report explained the sightings as misidentified conventional phenomena, a conclusion critics called public relations.

Sighting, USA

On 24 April 1949 a tracking team at White Sands used a theodolite to follow a second object they computed at about 56 miles up and seven miles per second; Edward Ruppelt could not explain it, and later accounts dispute the observer and the figures.

Radar visual, USA

On May 21, 1949, a silvery disc hovering over the Hanford nuclear site was confirmed on radar and by ground observers, prompting an F-82 interception from Moses Lake that failed to locate it; Air Force files later attributed the radar contact to a leaflet-dropping aircraft, a link the investigating officer disputed.

Sighting, USA

On 24 May 1949 a group fishing on the Rogue River in Oregon reported a round, silver object about the size of a C-47 that made no sound and left no exhaust; an Air Force OSI inquiry could not rule out an aircraft and the case was filed as unresolved.

Radar visual, Japan

On the night of 3 October 1951 a radar crew at Kadena Air Base on Okinawa tracked a large “sausage-shaped” target at speeds the Air Force later estimated at over 2,000 mph; a declassified intelligence analysis concluded it was probably a manufactured, possibly guided missile.

Radar visual, Japan

On 7 February 1953 five U.S. Air Force radar and ground personnel at a Hokkaido detachment watched a star-like, colour-changing light for about 35 minutes, and a radar return was logged and dismissed; the Far East Air Forces concluded it was probably a Soviet weather balloon.

Radar visual, Greenland (Denmark)

In 1953 the Air Force's Arctic air-defence outpost at Thule, Greenland, logged an unidentified radar track on a ground-controlled approach scope and a series of glowing lights seen by interceptor pilots.
