CIA-UAP-014, British activity in the Field of "Unidentified Flying Objects"
A December 1952 Memo on the activities the British are taking to identify UFOs. The memo references a UFO sighting at an RAF field seen by high officials and RAF pilots. A more redacted version of the memo has been available on CIA's public website.
The summary above is sourced from the released file metadata as published to war.gov. The analysis sections below are original to this tracker.
Where this file fits in the PURSUE archive
This file is one of CIA's 21 files in the Trump PURSUE disclosure. Within the CIA agency block it ranks #13 of 21 by Anomalousness Index. Across the entire 334-file archive it ranks #193 of 334.
That places it in the lower-scoring band of the archive (193 of 334 by score), typical of investigative-record style files where the report is paper-based rather than instrumented.
For the broader cluster context, this file is part of CIA UFO Files - the 21-file CIA cluster, from the 1953 Robertson Panel to the U-2 history and Cold War sightings. The cluster page walks through all 21 member files with regional grouping, sensor breakdown, and standout analysis.
Anomalousness Index: 58/100
Evidentiary weight that this encounter remains unexplained after conventional analysis. Not a probability of extraterrestrial origin - that number is not honestly computable from the released files and this tracker refuses to publish it.
🤖 AI-ASSISTED SCORING · methodology
The six rubric components break down for this file as follows. Each component has a weighted contribution to the final score; the per-component explanation below describes what this file's particular value on that component means in the rubric's framework.
No sensor, camera, or instrument backs this observation - it is testimony, relayed through the CIA, and scored on the rubric's lowest sensor-quality tier for that reason. That doesn't bear on the witness's credibility (a separate axis); it reflects only that nothing beyond human perception recorded the event.
The witness here is CIA personnel, entering the report into the federal investigative system through standard channels. That's a real credibility tier - trained federal investigative staff - though the rubric ranks it below mission-active military or astronaut testimony because the posture is reactive (responding to a report) rather than an active operational context.
On corroboration, this file from the CIA - like every single-tier file in the PURSUE archive - is a single-witness or single-instrument capture per the released metadata. The rubric doesn't infer multi-witness confirmation the summaries don't actually establish; this score reflects the honest limit of what was released, not a judgment about the underlying event.
The released file contains no speed, acceleration, or vector data precise enough to score on the kinematic axis - and that's true archive-wide, not specific to this file. The rubric declines to infer kinematic anomaly from a witness's narrative estimate of how fast something moved; that itself says something about what PURSUE actually released: descriptive accounts, not flight-path telemetry.
Every file in the archive, including this one, scores this tier: a conventional explanation was considered in the released record but isn't treated as dispositive. That's a pattern in how war.gov's own summaries are written - they consistently hedge against strong conclusions either way - and the rubric takes that hedging at face value rather than resolving it for them.
This file was released as open by the CIA after a formal review process concluded - not simply logged and left pending. That's a stronger disposition signal than 'unresolved, no review': a review actually happened, and remaining open is the CIA's own published conclusion from it, not an absence of one.
Bottom line on the score: the Anomalousness Index of 58/100 reflects evidentiary weight that this specific file's encounter remains structurally unexplained by the rubric's six axes - it is not a claim that the underlying event involved anything non-conventional, and it is not comparable across rubrics that use different weights.
