List of UFO Incidents

List of Major UFO / UAP Incidents in World History

S. No.	Incident / Event	Date / Location	Description / Evidence / Status
1	Battle of Los Angeles	February 1942, California, USA	Air-defence forces fired at objects or suspected aircraft during a wartime alert. The cause of the reported sightings remains debated; no confirmed extraterrestrial involvement.
2	Kenneth Arnold Sighting	June 1947, Washington, USA	Pilot Kenneth Arnold reported seeing unusual objects near Mount Rainier. The widely publicized report helped popularize the term "flying saucer."
3	Roswell Incident	July 1947, New Mexico, USA	Debris recovered near Roswell sparked claims of a crashed alien spacecraft. The U.S. Air Force later attributed the debris to a classified balloon-borne research project; alien recovery claims remain unsubstantiated.
4	Washington, D.C. UFO Incidents	July 1952, Washington, D.C., USA	Radar operators and observers reported unidentified targets near the capital. Investigations considered radar and atmospheric explanations; the episode remains a famous historical UFO case.
5	Lubbock Lights	August 1951, Texas, USA	Witnesses reported formations of lights moving across the sky, and photographs were publicized. The Air Force investigated the sightings and proposed birds reflecting streetlights as an explanation.
6	Levelland UFO Incident	November 1957, Texas, USA	Multiple reports described unusual lights and vehicle electrical problems. Project Blue Book attributed the events to electrical phenomena, although the explanation has been disputed.
7	Westall School Sighting	April 1966, Victoria, Australia	Students and other witnesses reported an unusual flying object near a school in Melbourne's suburbs. The precise explanation remains disputed, and extraterrestrial origin has not been established.
8	Shag Harbour Incident	October 1967, Nova Scotia, Canada	Witnesses reported a lighted object descending into the water. Searchers investigated the reported location, but no confirmed extraterrestrial craft was recovered.
9	Tehran UFO Incident	September 1976, Tehran, Iran	Military pilots were dispatched after reports of a bright object. Accounts described radar contact and instrument or weapons-system malfunctions; the incident remains unexplained in popular UFO literature.
10	Belgian UFO Wave	1989–1990, Belgium	Numerous witnesses reported large triangular objects. Some reports involved police and military investigations, but the sightings did not establish that the objects were extraterrestrial craft.
11	Rendlesham Forest Incident	December 1980, England, UK	U.S. military personnel stationed near RAF Woodbridge reported unusual lights in the forest. An official memorandum documented observations, but no verified alien spacecraft was recovered.
12	Trans-en-Provence Incident	January 1981, France	A witness reported an object descending near a property, followed by alleged physical traces. French investigators examined the case, but the evidence did not establish an extraterrestrial origin.
13	JAL Flight 1628 Encounter	November 1986, Alaska, USA	A Japanese cargo-aircraft crew reported unusual lights and a large object during a flight. The report attracted attention because of claims involving radar and crew observations; the object's identity remains disputed.
14	Varginha Incident	January 1996, Brazil	Witnesses alleged that unusual beings and a strange craft were encountered near Varginha. The story became a major UFO legend, but claims of alien capture have not been independently substantiated.
15	Phoenix Lights	March 1997, Arizona, USA	Many people reported lights or formations in the night sky. Some observations have been associated with military flares, while reports of other formations have different proposed explanations.
16	Ariel School Incident	September 1994, Ruwa, Zimbabwe	Schoolchildren reported seeing an unusual object and alleged beings near their school. Their accounts received international attention, but no independently verified evidence established extraterrestrial contact.
17	USS Nimitz Tic Tac Encounter	November 2004, Pacific Ocean, USA	U.S. Navy personnel reported an unusual object described as resembling a white Tic Tac. Military video and witness accounts made the case prominent; the object's identity and origin remain unconfirmed.
18	Chicago O'Hare Airport Sighting	November 2006, Illinois, USA	Airport personnel reportedly observed a disc-shaped object above the airport. The report received widespread media coverage, but no publicly verified evidence established an extraterrestrial craft.
19	Mexican Air Force Infrared Video	March 2004, Mexico	An aircraft crew recorded multiple infrared points of light. Proposed explanations have included distant industrial or other terrestrial sources; the footage does not independently establish anomalous craft.
20	USS Theodore Roosevelt Encounters	2014–2015, U.S. East Coast	Military aviators reported unusual objects during training flights. Several Navy videos later became widely known, but the objects' identities vary by case and are not evidence of confirmed extraterrestrial technology.
21	Gimbal Video Incident	January 2015, off the U.S. East Coast	A U.S. Navy infrared video showed an unidentified airborne object. The recording is authentic military footage, but its exact interpretation and the object's identity remain disputed.
22	GoFast Video Incident	January 2015, off the U.S. East Coast	A Navy video showed an object appearing to move rapidly above the ocean. Apparent speed can be affected by viewing geometry and camera motion; the video does not establish extraordinary performance.
23	USS Omaha Sphere Video	July 2019, Pacific Ocean	Military footage showed an object described as a sphere near a Navy ship. Publicly available information has not conclusively established the object's identity or extraterrestrial origin.
24	U.S. Congressional UAP Hearings	2022–2024, Washington, D.C., USA	Military personnel and other witnesses testified about unidentified anomalous phenomena. Testimony raised questions about reporting and oversight but did not publicly establish that aliens have visited Earth.
25	Recent Military UAP Reports	2020s, various locations	Military personnel have reported unidentified objects and sensor observations. Official investigations distinguish unresolved cases from objects explained by balloons, drones, satellites, atmospheric effects or other ordinary causes.

Notes:

UFO means "Unidentified Flying Object." UAP means "Unidentified Anomalous Phenomena," a broader term used in modern official reporting.
An unidentified observation means that available information is insufficient to determine what was seen. It does not automatically indicate an alien spacecraft.
Some incidents have multiple witnesses, photographs, videos, radar reports or official records, but these forms of evidence differ in quality and do not necessarily establish the object's identity.
Roswell remains one of the most famous UFO incidents, but the U.S. Air Force's historical explanation attributed the recovered debris to a balloon-borne research project.
The Nimitz, Gimbal and GoFast cases involve genuine military reporting or footage; the exact identity of an object must be assessed separately from the authenticity of a recording.
No UFO incident in this list has conclusively established that extraterrestrial beings or spacecraft have visited Earth.
The list is a selection of notable historical cases, not a ranking of the strongest evidence for extraterrestrial life.
