Summary
This file is a collection of internal U.S. Army correspondence and memoranda spanning February 24 to April 20, 1949, generated by the Plans and Operations Division (P&O) of the General Staff, U.S. Army, in connection with its formal request for an evaluation study of the flying saucer phenomenon. The file includes cover sheets (Combined Routing-Information-Filing Forms), disposition forms, outbound dispatch records, and the evaluation study itself. The study was prepared by the Intelligence Division (ID) and forwarded to P&O on 7 March 1949.
The core finding of the Evaluation Study, as summarized in the document and recorded in the transmittal memoranda, was: "Evaluation study was prepared at request of P&O to determine if the various reports on this subject stemmed from natural phenomena or if the origin could be traced definitely to the activities of a foreign power." The ID's study indicated "of all cases investigated there was no foreign nation implication in these flying saucers."
A secondary driver for the file's later documents was broadcaster Walter Winchell's April 3, 1949 broadcast about flying saucers, which prompted P&O to ask ID to verify Winchell's accuracy.

Origins: Why the Army Asked the Question
The file opens with a memorandum for record dated February 24, 1949, from Lt. Col. Peisinger of the Executive Branch, P&O. It notes that conversations with the Chief of North American Branch and the Office of Deputy Director P&O (AE) "reveal that P&O has not received any evaluation of the flying saucer type of phenomenon." The memo further states that the North American Branch "feels that P&O, and themselves in particular, have a direct interest in this phenomenon because, until it is properly evaluated, a possibility exists that this phenomenon may have foreign implication."
Col. Ligon of the Intelligence Group, ID, suggested that the division request ID to make a study on the subject "insofar as it pertains to continental U.S." Three Air Force radio messages from Kirtland AFB and Wright-Patterson AFB (dated February 2, 8, and 19, 1949) were cited as the triggering operational context.
The Evaluation Study: Findings
The Evaluation Study — one page of substantive analysis, classified CONFIDENTIAL — was prepared by a special project group at Headquarters, Air Materiel Command, Wright-Patterson Air Force Base, Ohio. The study covered incidents reported from June 1945 to the date of writing.
Key findings, verbatim from the document:
"Detailed investigations of all incidents reported to involve unusual flying objects during the period June 1945 to date have been conducted by a special project group of Headquarters, Air Materiel Command, Wright-Patterson Air Force Base, Ohio."
"Of some 210 incidents, approximately twenty (20) per cent have been explained. The majority of these involved misidentification of synoptic weather balloons. Others involved observations of airborne cosmic ray research equipment, bolides, meteors, and in one instance, the daylight observation of the planet Venus. Only two reported incidents were determined to have been hoax."
"To date there has been no tangible evidence which would support a theory that any incidents are attributable to activity of a foreign nation. There are no highly secret experimental Projects of the U.S. Government that could be responsible."
"The ID feels that if complete data were available the remaining 80% of the reported sightings could be eliminated as due to natural meteorological phenomena or domestic weather balloons and the like."
The Walter Winchell Episode
A later document in the file, a memorandum for record dated April 20, 1949 from Maj. J. S. Byrne, records that following Walter Winchell's April 3, 1949 broadcast about flying saucers, "the D/F Cmt #1 was sent to ID requesting verification of the accuracy of the broadcast." ID's response (D/F Cmt #2) constituted the official Army reply. This episode illustrates the degree to which public media discourse about flying saucers was actively monitored by the Army staff and treated as a coordination issue requiring official response.
Significance
This file is the Army's earliest known formal internal study of the flying saucer phenomenon. It documents the institutional decision-making process by which a major military staff division moved from informal awareness of reports to a structured intelligence request, received an official assessment, and established a standing requirement for ID to inform P&O of any future changes in that assessment. The 210-incident baseline, the 20% explained rate, and the explicit exclusion of foreign-nation and U.S. government secret-program explanations make this document a foundational record in the official U.S. government effort to evaluate UAP.

This file contains one of the most important military documentation collections in the history of UAP research. It includes the famous Twining Letter of September 23, 1947, in which a senior U.S. Army officer formally declared that the flying disc phenomenon is "real and not visionary or fictitious." The file documents a complete chain of classified correspondence between Air Materiel Command and Air Force headquarters, and offers an unprecedented view into American military thinking during the founding months of the flying saucer era.

DOW-UAP-D087: U.S. Air Force Analysis of Flying Objects in the United States — Incident Summaries 1–100
The first volume of a two-part declassified collection of U.S. Air Force "Check-List — Unidentified Flying Objects" incident summaries, covering incidents numbered 1 through 100. The summaries were compiled by the Air Materiel Command at Wright-Patterson Air Force Base under Project Sign (later Project Grudge), and forwarded under a Secret routing slip dated 3 March 1949. Each check-list records a standardized set of 26 fields: date, time, location, observer identity and occupation, object count, altitude, speed, direction, maneuvers, sound, size, color, shape, odor, apparent construction, exhaust trails, weather, effect on clouds, sketches or photographs, manner of disappearance, and narrative remarks. The incidents span July 1947 onward and include multi-witness sightings confirmed across observers, with evaluations ranging from "confirmed by other sources" to identified natural or man-made phenomena. This volume is a companion to DOW-UAP-D088, which covers incidents 101–172.

DOW-UAP-D085: Transmission of the CIA Robertson Panel Report to the Secretary of Defense, 1953
A declassified file comprising the Secretary of Defense routing slip, a CIA cover letter dated 13 March 1953, and the full text of the "Report of the Scientific Panel on Unidentified Flying Objects" (the Robertson Panel report), dated 17 January 1953. The CIA, at the direction of DCI General Walter Bedell Smith, forwarded the panel's conclusions and recommendations to the Secretary of Defense. The panel — chaired by H. P. Robertson of Caltech and including physicists Luis Alvarez, S. A. Goudsmit, Lloyd Berkner, and Thornton Page — concluded that UFOs posed no direct physical threat to national security but that the continued reporting of them represented an indirect danger: the risk of clogging intelligence communication channels and making the public susceptible to enemy psychological operations. The panel recommended a national program to strip UFOs of their "aura of mystery."
