It is held by rocketry experts (example, WILLY LEY - see his ROCKE'IS, p. 192, diagram and note in connection there­ with) that it wol,ll.d take about 100 hours f or a rocket-craf t to negotiate the di stance from Earth to Moon. Prior to its ~xplosion over Norcatur, this object of Feb. 18th was variously reported as a "falling plane", a "jet plane", and a ''ball of fire11 It is said by some to have l eft a trail of smoke behind it. It is the suggestion of this writer that the Army collect assimilate reports on this object , with a view t o determining where it was seen as an object trailint: smoke and llhe re as a ball of fire. If this thing is a r ocket of some kind headed for the moon, it might first have been seen as a streak of sr.oke, then later as a ball of fire, and lastly as a tremendous ex­ plosion when it at last reached sufficient speed and eleva­ tion for take-off. The writer has in mind the various and unexplained r e1.,orts on "!lying saucers", and bases this speculation upon a lonb c onsideration of various oddments of reports whose significance might be of epace-craft f r om other worlds of The so-called "meteori c procession" which crossed Tor ont o in February 1913, consisted of a number of u oups or illimunated bodies traveling in v oups of three an:l moving in "rigid formation", all pursuing a course acr oss the same streak of the earth's surface. J.r a line is projected backward along ·t his line of fli ght it will be seen that this line "comes out" at the position of the moon at the time. The 1913 phenomenon occurred in the mid-period of a series of reports on dirigible aircraft of appearance like zeppelins which were seen over :&, gland an:i whose appearance terminated - or reports on the appearances stopped - j ust prior to the inferior conjt.mction of Venus of April 1913. The writer begs to call attention to the f act that the times prior to and just after inferior conjunction of Venus are prolific in reports of strange t hings seen in the sky. Also t}at lights have been reported on the moon from time to time, back f or at l east a century. Ir in thr future of mil itary experiment the moon is selected as a base for the launching of r ockets (which has been suggested by some writers), it may be wel l to look first

From: Norman G. Uarkham MAIN HOT£L, Pueblo, Colo To: Chief ~ignal Of ficer Subject: Norcatur, ~s., sky explosion ing tho above phenomenon and another one of earlier date and to call attention to occurrences between the two which have an appearance of dental or not. The geographical position of the Norcatur explosion suggests possible linka.!;8 with other occurrences happening inside latitooinal limits arbitrarily demarkable between 43° 36 1 North (which is the latitooe of Ooise, Idaho) miles wide. 'lbis suegestion is gained from positions given for occurrences hereinaft er briefly described, THE OOISE (Idaho) OBJECT- This was seen either beginnin{.! or ending at 330 pm 24 June 1947 am was visible for 20 minutes. It was in the western sky, was of comet-li~ appearance, and settled gradually toward the horizon ae planetary bodiea set. It was seen bo.r Lt. Gov. Whitehead •u)j Chief Justice Lartpert. Its nature was unknmm . The peculiarity which connects this object, for speculative purposes, with the explosion of some unknown object over 1~orcatur, Kans ., on 18 l!'ebruary 1948 is the seeming of a relationship between the positions of the moon for the two phenomena:

Where this file fits in the PURSUE archive

This file is one of DoD's 257 files in the Trump PURSUE disclosure. Within the DoD agency block it ranks #148 of 257 by Anomalousness Index. Across the entire 450-file archive it ranks #272 of 450.

That places it in the lower-scoring band of the archive (272 of 450 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

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.

witness credibility (military personnel) 80 × 0.2 = 16.0

Reported by trained U.S. military personnel during an operational mission (2026-06-12) - 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.

corroboration (single witness instrument) 60 × 0.2 = 12.0

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.

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

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.

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

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.

official disposition (open after review) 90 × 0.1 = 9.0

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. For the full per-axis weights and the rubric JSON, see /methodology.
