DOW-UAP-D158, Flying Object Report, Canada, 1953
This document is a Flying Objects Report prepared in accordance with Air Force Regulation 200-2, which established guidance for reporting unidentified flying objects. This report records a November 13, 1953, incident in British Columbia, Canada, in which three U.S. Air Force servicemembers reported observing a round, blinking white light with a blue hue, initially described as resembling a falling star. The report describes the object’s motion as descending to an estimated altitude of 150 feet, remaining stationary for approximately 30 seconds, ascending vertically to an estimated altitude of 300 feet, remaining stationary for approximately 10 seconds, and then departing the observers’ field of view in a westerly direction while gaining altitude. All descriptive and estimative language contained in this report reflects the reporter’s subjective interpretation at the time of the event. Such characterizations should not be interpreted as a conclusive indication of the presence or absence of any intrinsic object features or performance characteristics.

Where this file fits in the PURSUE archive
This file is one of DoD's 282 files in the Trump PURSUE disclosure. Within the DoD agency block it ranks #164 of 282 by Anomalousness Index. Across the entire 478-file archive it ranks #288 of 478.
That places it in the lower-scoring band of the archive (288 of 478 by score), typical of investigative-record style files where the report is paper-based rather than instrumented.
Anomalousness Index: 56/100
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 Department of War, 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.
Reported by trained U.S. military personnel during an operational mission (11/13/1953) - a high witness-credibility tier, ranked in the rubric below astronaut, trained-aviator, and federal-agent testimony. This profile is shared across the AARO-submitted infrared-capture cluster that anchors the archive's densest scoring band, at 66.
On corroboration, this file from the Department of War - 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 Department of War 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 Department of War's own published conclusion from it, not an absence of one.
Bottom line on the score: the Anomalousness Index of 56/100 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.

This hash is the SHA-256 of the file body war.gov served on the verification date above. War.gov has re-processed some file bodies since first release (re-compression + OCR, no content removed - see /changes); we re-verify and record the change rather than silently serve a stale hash.
