Civilian pilot Kenneth Arnold reports nine crescent-shaped objects flying at 1,200 mph near Mount Rainier, Washington. A newspaper misquotes his description, and "flying saucer" enters the lexicon. The modern UFO era begins.

RAAF public affairs officer Walter Haut issues the press release heard round the world. Within hours, the Army retracts it. The cover-up that would define the next 75 years begins the same day it starts.

Multiple unidentified craft tracked on radar over Washington DC and Andrews AFB on two consecutive weekends. F-94 interceptors scrambled. Objects outrun jets and appear to respond to pursuit.

Over 200 students and teachers watch a silver craft land, hover, and depart at speed. Officials arrive within hours and warn witnesses to stay silent.

Stefan Michalak's encounter with a landed craft leaves a precise grid-burn pattern across his chest. Physical evidence — radiation, melted materials, the burn pattern — survives decades of investigation intact.

The US Air Force closes its 22-year public UFO investigation program. The Condon Report concludes study is not worthwhile. Many researchers believe it was cover by design — not a genuine investigation.

Charles Hickson and Calvin Parker are taken aboard a craft by robotic beings while fishing. Both pass polygraph examinations. Dr. J. Allen Hynek interviews them and finds no deception.

Logger Travis Walton vanishes for 5 days after being struck by a beam from a hovering craft. Six eyewitnesses pass polygraph tests. His is the most corroborated abduction case in history.

A giant jellyfish-shaped object hovers over a Soviet city for 12 minutes. TASS — the official state news agency — reports it. Pitted glass and elevated readings remain unexplained.

Japanese Airlines pilot Capt. Terauchi tracks two craft and a massive mothership for over 31 minutes. FAA radar independently confirms unidentified traffic in proximity to the aircraft.

Physicist Bob Lazar tells investigative reporter George Knapp he worked on reverse-engineering alien craft at a classified facility south of Area 51. His technical descriptions are detailed, internally consistent, and partially corroborated by subsequent declassifications.

62 schoolchildren witness a craft land and beings emerge at their school in Ruwa. Harvard psychiatrist Dr. John Mack flies to investigate and concludes the children experienced something genuinely inexplicable.

Three women encounter a strange being in broad daylight. Military activity spikes across the region. Multiple witnesses describe a Brazilian Army operation to capture living non-human beings.

Thousands of Arizona residents — including the governor — watch a massive silent craft traverse 300 miles of sky. One of the largest mass UFO events in American history. Governor Symington later admits he saw it too.

Navy pilots encounter a white Tic-Tac shaped craft demonstrating performance impossible with known physics. FLIR footage captured. Pentagon would not acknowledge the encounter for 13 years.

The Department of Defense formally declassifies and releases the FLIR1 (Tic-Tac), GIMBAL, and GOFAST videos. The release confirms their Navy provenance; it does not identify their contents as extraterrestrial.

The Office of the Director of National Intelligence releases its unclassified UAP report. 144 incidents examined. 143 unexplained. The report says limited data prevent firm conclusions about most reports; lack of identification is not a finding of extraterrestrial origin.

The House Intelligence Subcommittee holds the first public congressional UAP hearing since 1969. Deputy Director of Naval Intelligence confirms ongoing encounters. Stigma in the military begins to crack.

The August release includes historical film analysis and FBI records, including witness-based digital renderings.

The Department announced a sixth release on September 18 and said further releases are in preparation. Browse the official collection for the complete batch.
