Case files
Tehran Dogfight
Two Imperial Iranian Air Force F-4s scrambled on an object that reportedly knocked out their instruments and weapons. Documented in a US DIA memo.
The Colares Incident
For months an island village at the mouth of the Amazon reported low-flying lights that burned people — the chupa-chupa. Brazil's air force spent four months watching with cameras, and its own files are now in a public archive.
Shag Harbour Incident
Something crashed into the harbour and sank; the RCMP and Navy searched. Canada’s files list it as an unsolved UFO case.
O’Hare Airport Sighting
United Airlines staff reported a disc hovering over Gate C17 before it shot upward, punching a hole in the cloud deck.
USS Nimitz “Tic Tac” Encounter
Navy F/A-18 pilots and the Nimitz strike group tracked a 40-foot wingless “Tic Tac” on radar and gun-camera. One of the best-sensored military cases on record.
Japan Air Lines Flight 1628
A JAL cargo 747 crew tracked enormous craft over Alaska for nearly an hour. The FAA investigated and never fully explained it.
Levelland Vehicle Interference
A dozen drivers independently reported an egg-shaped object that stalled their engines and headlights, then departed.
The Falcon Lake Incident
A Winnipeg mechanic prospecting for quartz said a domed disc landed on the rock beside him and vented hot gas that seared a grid of burns across his chest. The RCMP, the RCAF and the USAF all examined the man, the site and the samples, and none of them closed the file.
The Phoenix Lights
Thousands watched a silent V-formation of lights cross Arizona. Flares explain part of it; the earlier craft sightings less so.
Malmstrom Missile Shutdown
Officers reported a craft over the base as a flight of Minuteman ICBMs dropped offline. Corroborated by multiple missileers.
Washington D.C. Flap
Unknowns painted on radar over the capital two weekends running, prompting jet intercepts and a hurried Air Force press conference.
Roswell Incident
Debris on a ranch, a press release that said “flying disc,” then a hasty walk-back to “weather balloon.” The founding myth of modern ufology.
Stephenville Lights
Dozens of residents, including a pilot, reported a mile-wide craft. FAA radar data later showed unexplained tracks in the area.
Varginha Case
Locals claimed the military captured a strange creature. Enormously popular in Brazil, thin on hard evidence.
Trans-en-Provence Case
A farmer reported a landed disc; France’s GEPAN found unusual soil and plant changes at the site. A rare physical-trace investigation.
Trindade Island Photos
A Brazilian Navy expedition photographed a Saturn-shaped object. The negatives were vouched for by the government of the day.
Rendlesham Forest
USAF personnel near RAF Woodbridge reported a landed craft and radiation traces. Britain’s most documented military case.
Cash–Landrum Incident
Two women reported a diamond-shaped craft escorted by helicopters, then suffered burns and radiation-like illness.
Kecksburg UFO
A fireball, then reports of an acorn-shaped object recovered by the military. Officially a meteor; locally, something else.
Lakenheath–Bentwaters Radar-Visual Case
Over six hours, three ground radars, a night fighter's airborne set, a C-47 pilot and two control towers all reported the same intruder over Suffolk. The Condon Report — the study that shut American UFO research down — called it the most puzzling case in its radar-visual files.
Aguadilla Thermal Video
A Customs and Border Protection aircraft filmed an object skimming the sea and apparently splitting in two on infrared.
Westall School Sighting
Some 200 students and staff watched a craft descend near their school. One of the largest mass sightings on record.
The Belgian Wave
Months of triangular-craft reports, backed by police witnesses and an F-16 radar-lock chase the Belgian Air Force openly investigated.
Area 51 / S-4
Bob Lazar claimed he reverse-engineered alien craft at a site south of Groom Lake. The physics is intriguing; the corroboration is thin.
Hudson Valley Sightings
Years of huge, silent boomerang-craft reports across the New York–Connecticut border. Some, but not all, tied to hoaxing pilots.
