REDACTED

This file contains an independent report on UFOs written by the French association COMETA (previously published in the French magazine VDS in 1999), which details the results of a study by the Institute of Higher Studies for National Defence. The file also includes a letter from Carol Rosin in which she notes that she was spokesperson for von Braun during the last years of his life.

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 NASA's 40 files in the Trump PURSUE disclosure. Within the NASA agency block it ranks #40 of 40 by Anomalousness Index. Across the entire 334-file archive it ranks #209 of 334.

That places it in the lower-scoring band of the archive (209 of 334 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.

sensor quality (eyewitness only) 30 × 0.25 = 7.5

Reported by a witness with no instrumented record. The lowest tier in the rubric's sensor axis. Eyewitness perception in field conditions, even when the witness is highly credentialed, scores below capture by any instrumented modality. This report reached the federal record through NASA.

witness credibility (astronaut) 95 × 0.2 = 19.0

Astronaut witness on the official federal record - the highest tier in the rubric's witness-credibility axis. It applies to NASA crew debriefings, mission transcripts, and astronaut interviews across the Mercury, Gemini, and Apollo programs. Witness credibility is only one of six components; the astronaut-witness files that also rank high on the sensor and disposition axes are the eight tied for the archive's top score of 72 - the Gemini 7 Borman audio, the Gordon Cooper interview, and the Apollo 14, 16, and 17 crew debriefings.

corroboration (single witness instrument) 60 × 0.2 = 12.0

Single-witness or single-instrument capture. This is the corroboration tier for the overwhelming majority of the PURSUE archive on the released metadata - the rubric records the honest limit of the underlying record rather than inferring multi-witness corroboration that the released summaries do not establish. A small number of files with an independent second witness or instrument score on the multi-witness/multi-instrument tier above this one.

kinematic anomaly (no kinematic data) 30 × 0.15 = 4.5

No kinematic measurements - speed, acceleration, vector - are published in the released file with sufficient precision to score on the kinematic axis. The rubric does not infer kinematic anomaly from narrative observer estimates. Every file in the archive carries this value, which is itself an observation about the disclosure: kinematic-grade telemetry was not part of what was released.

mundane explanation available (weak mundane candidate) 70 × 0.1 = 7.0

A conventional candidate explanation has been considered but is not dispositive. Every file in the archive scores this way - reflecting that the underlying release metadata systematically caveats strong determinations in either direction. The released summaries warn against reading them as conclusive analytical judgments, and the rubric respects that.

official disposition (unresolved no review) 60 × 0.1 = 6.0

Catalogued as unresolved with no formal review process having concluded. This is the disposition for a large share of the archive's military infrared captures - the reports are logged into the system as unresolved, but no formal review has finalized. The rubric distinguishes this from 'open after review' because the absence of review is itself a status signal.

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.
