Declassified Project Sign file: 298-page dossier of Colonel Howard McCoy at Wright-Patterson AFB — Historical unsealing in PURSUE Release 07: 298-page personnel and intelligence file of Colonel Howard McCoy, the Wright-Patterson intelligence director who launched Project Sign.

Executive Summary

Tucked within the Pentagon’s October 2026 PURSUE Release 07 is a newly declassified 298-page dossier detailing the career, internal correspondence, and classified research directives of Colonel Howard Monroe McCoy. As Chief of the Intelligence Department at Wright-Patterson’s Air Materiel Command (AMC) from 1947 to 1949, McCoy was the operational architect who launched Project SIGN—the United States Air Force’s very first formal UFO investigation—and oversaw the drafting of the legendary 1948 "Estimate of the Situation." Here is what the unsealed file reveals about McCoy’s intelligence network, foreign technical exploitation, and the origins of modern military secrecy surrounding anomalous craft.

The 298-page dossier on the Air Force intelligence chief who led Project Sign

For military historians and aerospace researchers, Colonel Howard Monroe McCoy (1905–1972) is one of the most enigmatic figures of early Cold War technical intelligence. An aeronautical engineer who spearheaded Operation LUSTY (exploiting captured Nazi jet and rocket technology in Europe) and served as the chief of AMC Intelligence (T-2) at Wright Field, McCoy sat at the nexus of foreign threat evaluation and anomalous aerial reports during the explosive 1947 flying disk wave.

The Architect of Project SIGN: General Twining’s Mandate

When General Nathan Twining authored his seminal September 23, 1947 memorandum declaring that "the phenomenon reported is something real and not visionary or fictitious," it was Colonel Howard McCoy who received the order to build the investigative infrastructure.

McCoy organized Project SIGN within the T-2 Intelligence Division at Wright Field (later Wright-Patterson Air Force Base).
He assembled aeronautical engineers, radar specialists, and materials scientists from the Air Materiel Command to conduct technical evaluations of civilian and military sighting reports.
The newly unsealed dossier includes McCoy’s initial routing slips establishing strict classification protocols for incoming pilot affidavits, ensuring technical data bypassed standard press channels.

The 1948 "Estimate of the Situation" and the Vandenberg Order

The central historical mystery of early Air Force UAP research has always been the late-summer 1948 "Estimate of the Situation"—a top-secret document in which Project SIGN staff concluded that UFOs were interplanetary vehicles.

The unsealed McCoy papers confirm that McCoy reviewed, approved, and forwarded the Estimate of the Situation up the chain of command to Air Force Chief of Staff General Hoyt Vandenberg.
General Vandenberg famously rejected the conclusion on the grounds that the team lacked tangible physical wreckage to substantiate an extraterrestrial hypothesis.
Vandenberg ordered all copies of the Estimate recalled and incinerated; McCoy’s dossier contains contemporaneous bureaucratic logs recording the physical de-accessioning and destruction instructions.

Operation LUSTY, German Saucers, and Soviet Aerospace Scrutiny

Before leading Project SIGN, McCoy was renowned as the military leader of Operation LUSTY (Luftwaffe Secret Technology), confiscating advanced German wind tunnels, swept-wing designs, and rocket prototypes.

Because of his intimate knowledge of Horten brothers flying-wing prototypes and supersonic aerodynamics, McCoy was uniquely qualified to assess whether "flying disks" were secret Soviet adaptations of captured Nazi technology.
Declassified memos in the 298-page file prove that by mid-1948, McCoy’s intelligence staff conclusively ruled out Soviet origin, noting that Soviet metallurgy and propulsion lagged far behind the speeds and maneuvers logged by U.S. radar stations.
This technical conclusion left AMC analysts with only two possibilities: an unprecedented American covert program operating outside AMC oversight, or non-terrestrial phenomena.

Why the 298-Page Dossier Resurfaces in PURSUE Release 07

The timing of the McCoy dossier’s inclusion in PURSUE Release 07—alongside modern 2026 sensor captures—provides critical institutional context for how defense agencies handle persistent anomalous tracking.

Historical Precedent: The files reveal that internal friction between technical evaluators and top brass has existed since the inception of military UFO investigation in 1947.
Archival Traceability: Unredacted routing stamps and personnel serial numbers in the McCoy dossier establish an unbroken custodial chain leading into Project Grudge and Project Blue Book.
Validation of Whistleblower Historical Timelines: The unsealed memos corroborate timelines described by modern whistleblowers regarding when early aerospace crash-retrieval evaluations were compartmentalized into Special Access Programs.

Key findings from Colonel Howard McCoy’s unsealed intelligence dossier

PURSUE Release 07 unseals a 298-page declassified intelligence record on Col. Howard McCoy, chief of AMC Intelligence during the 1947–1949 UFO waves.
McCoy directly oversaw Project SIGN and authorized the drafting of the 1948 Estimate of the Situation, which concluded unidentified craft were extraterrestrial.
The dossier documents internal resistance from Air Force Chief Hoyt Vandenberg, who ordered the Estimate de-accessioned and burned due to lack of physical debris.
Technical memoranda show McCoy systematically eliminated Soviet secret weapons as the explanation for anomalous performance characteristics observed over U.S. atomic installations.

How to analyze Cold War technical intelligence records alongside modern UAP disclosures

The strongest reading starts with the primary record, then follows the supporting documents, dates, agency labels, and public statements around it. When commentary or reporting adds context, it is weighed against the source record instead of being treated as the record itself.
