1950–1959 · 6 events in the archive
The Cold War decade. Project Blue Book opens at Wright-Patterson in 1952; the Robertson Panel reviews the UFO problem for the CIA in January 1953; UFO objects are tracked by air-traffic-control radar over the National Capital Region during the July 1952 Washington flap.
The 1950s record is dominated by the Air Force investigative arc — Sign giving way to Grudge, Grudge to Blue Book — and by the CIA's institutional response in the form of the Robertson Panel. The panel's recommendation that the public 'reaction' to UFOs be managed through education and counter-amateur-investigation measures shaped US government UFO communication for the next four decades.
Notable non-US material includes the September 1957 RB-47 incident (electromagnetic-interaction case over the southern United States), the 1955 Kelly–Hopkinsville encounter in Kentucky, the 1957 New Mexico Sandia–Kirtland sightings, and the contemporaneous European reporting collected by the French Gendarmerie that would later become GEIPAN's pre-1977 archive.
Why this matters. The 1950s is when the institutional posture solidifies. The 'unknown but unimportant' framing that Robertson recommended became the operational default and remained so until the 2017 NYT story.

PURSUE Release 03 publishes the CIA's 1952-1953 Scientific Advisory Panel on Unidentified Flying Objects — the Robertson Panel — in less-redacted form, with the Department of War's own transmission copy to the Secretary of Defense. The panel found no direct physical threat but warned that public fascination could clog intelligence channels and that a 'morbid national psychology' could be exploited by adversaries — and recommended an official policy of 'debunking' to 'strip the UFO subject of its mystery.'
Across two consecutive weekends, multiple radar installations and visual observers track unidentified objects above the restricted airspace surrounding the U.S. Capitol and White House. The Air Force convenes its largest press conference since World War II to address the events.
