AARO HRR Vol I, Pentagon Canonical PDF

Report on the Historical Record of U.S. Government Involvement with Unidentified Anomalous Phenomena, Volume I, media.defense.gov canonical PDF

AARO's February 2024 mandatory historical review concludes, across all classification levels, that no U.S. government program has ever recovered, reverse-engineered, or concealed extraterrestrial technology or biological material.

Brief

Covering 1945 through 2023, AARO reviewed classified and unclassified archives and conducted approximately 30 interviews before determining that every named hidden reverse-engineering program either does not exist, is a misidentified legitimate national security effort, or resolved to a disestablished and meritless proposal. A physical sample from an alleged crashed off-world spacecraft, acquired from both a private UAP organization and the U.S. Army, was analyzed and found to be a terrestrial magnesium-zinc-bismuth alloy with no exceptional properties. The persistent cover-up narrative is attributed largely to circular reporting among a consistent group of individuals active in UAP-related endeavors since at least 2009, many connected to the cancelled DIA program AAWSAP and the subsequently rejected DHS proposal KONA BLUE. None of the interviewees who made claims about secret programs had firsthand, authorized access to any of them.

Key points

  • AARO found no evidence, at any classification level, that any UAP sighting has been confirmed as extraterrestrial technology.p.7
  • A physical sample from an alleged crashed ET spacecraft, acquired from a private UAP organization and the U.S. Army, was determined to be a manufactured terrestrial alloy of magnesium, zinc, and bismuth.p.8
  • The alleged 1961 Special National Intelligence Estimate on UFOs, cited in UAP circles as evidence of a cover-up, was assessed as inauthentic.p.8
  • KONA BLUE, a proposed DHS Prospective Special Access Program for UAP recovery and reverse-engineering, was never approved and its proponents never provided empirical evidence.p.9
  • An IC Controlled Access Program had its scope expanded in 2021 without sufficient justification to cover UAP reverse-engineering; it was subsequently disestablished for lack of merit.p.9
  • None of the interviewees had firsthand, authorized access to the programs they described, a finding AARO cites as the likely root of misidentification.p.9
  • A military officer's claim that he physically touched an extraterrestrial spacecraft was denied by the officer himself, who described touching an F-117 Nighthawk stealth fighter.p.8
  • All named aerospace companies denied, on the record, ever possessing or reverse-engineering off-world technology.p.8
  • The persistent reverse-engineering narrative is attributed to circular reporting among a group of individuals active in UAP efforts since at least 2009.p.9
  • AARO's historical survey spans from Project SAUCER (1946/1947) through AARO's own establishment on July 15, 2022.p.2

Verbatim

  • AARO found no evidence that any USG investigation, academic-sponsored research, or official review panel has confirmed that any sighting of a UAP represented extraterrestrial technology. All investigative efforts, at all levels of classification, concluded that most sightings were ordinary objects and phenomena and the result of misidentification.
    p.7
  • Since 1945, the USG has funded and supported UAP investigations with the goal of determining whether UAP represented a flight safety risk, technological leaps by competitor nations, or evidence of off-world technology under intelligent control.
    p.6
  • The proliferation of television programs, books, movies, and the vast amount of internet and social media content centered on UAP-related topics most likely has influenced the public conversation on this topic, and reinforced these beliefs within some sections of the population.
    p.6
  • AARO has found no evidence of any authentic UAP-related NDA or other evidence threatening death or violence for disclosing UAP information.
    p.7
  • AARO has concluded that a sample from an alleged crashed off-world spacecraft that AARO acquired from a private UAP investigating organization and the U.S. Army is a manufactured, terrestrial alloy and does not represent off-world technology or possess any exceptional qualities.
    p.8
  • It is important to note that none of the interviewees had firsthand knowledge of these programs—they were not approved for access to nor did they work on these efforts—which likely resulted in misinterpretation of the programs' origins and purpose.
    p.9
  • AARO assesses that the inaccurate claim that the USG is reverse-engineering extraterrestrial technology and is hiding it from Congress is, in large part, the result of circular reporting from a group of individuals who believe this to be the case, despite the lack of any evidence.
    p.9

Most interesting

  • The 1961 Special National Intelligence Estimate on UFOs, widely cited in UAP circles as a leaked confirmation of ET reality, was assessed by AARO as a fabrication, not a suppressed government document.
  • A physical sample from an alleged ET crash entered U.S. Army custody at some point before being transferred to AARO for testing; it proved to be conventional metallurgy with no anomalous properties.
  • KONA BLUE was not a fringe proposal: it was a formal Prospective Special Access Program submitted to the Department of Homeland Security, backed by individuals who genuinely believed the USG held off-world technology.
  • An IC program quietly expanded its scope in 2021 to cover UAP reverse-engineering without sufficient justification, then was disestablished when it produced no evidence, an episode largely unknown outside classified channels.
  • Every foreign government UAP investigatory program reviewed by AARO reached the same general conclusions as U.S. investigations, a detail the report flags as underreported.
  • The military officer whose story became an interviewee claim about touching an alien spacecraft apparently was describing an encounter with an F-117 Nighthawk, so classified at the time that the confusion, while incorrect, is historically legible.
  • AARO states it was granted full, unrestricted access by all organizations investigated, a direct contradiction of the bureaucratic-obstruction narrative prominent in congressional testimony.
