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.
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 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.
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.
