Report on the Historical Record of U.S. Government Involvement with Unidentified Anomalous Phenomena, Volume I

AARO says its review covered official U.S. government UAP investigations since 1945, classified and unclassified archives, approximately 30 interviews, and oversight officials responsible for controlled and special-access programs.

AARO reviewed all official USG investigatory efforts since 1945, researched classified and unclassified archives, conducted approximately 30 interviews, and partnered with Intelligence Community (IC) and Department of Defense (DoD) officials responsible for controlled and special access program oversight, respectively.

AARO reports that no U.S. government investigation, academic research effort, or official review panel confirmed that a UAP sighting represented extraterrestrial technology.

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.

The report acknowledges that many UAP cases remain unresolved and attributes that condition largely to missing, limited, or poor-quality data.

Although many UAP reports remain unsolved or unidentified, AARO assesses that if more and better quality data were available, most of these cases also could be identified and resolved as ordinary objects or phenomena.

AARO reports finding no empirical evidence that the U.S. government or private companies have reverse-engineered extraterrestrial technology.

AARO found no empirical evidence for claims that the USG and private companies have been reverse-engineering extraterrestrial technology.

AARO says its analysis of a sample alleged to come from a crashed off-world spacecraft identified a manufactured terrestrial alloy without exceptional qualities.

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.

AARO assesses that alleged hidden reverse-engineering programs named by interviewees were nonexistent, misidentified sensitive programs unrelated to extraterrestrial exploitation, or an unwarranted program that was later disestablished.

all of the named and described alleged hidden UAP reverse-engineering programs provided by interviewees either do not exist; are misidentified authentic, highly sensitive national security programs that are not related to extraterrestrial technology exploitation; or resolve to an unwarranted and disestablished program.

The report says none of the interviewees had firsthand knowledge of the alleged programs because they had neither access to nor worked on them.

none of the interviewees had firsthand knowledge of these programs—they were not approved for access to nor did they work on these efforts

AARO attributes much of the reverse-engineering and congressional-concealment narrative to circular reporting among a recurring group of proponents rather than evidence supplied to its inquiry.

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.

AARO assesses that some sightings since the 1940s were misidentifications of unfamiliar experimental or operational space, rocket, air, stealth, or drone systems.

some portion of sightings since the 1940s have represented misidentification of never-before-seen experimental and operational space, rocket, and air systems, including stealth technologies and the proliferation of drone platforms.

AARO says its historical research identified approximately two dozen U.S. government UFO or UAP investigative efforts, depending on how related programs and reviews are counted.

AARO reviewed official USG efforts involving UFOs/UAP since 1945. This research revealed the existence of approximately two dozen separate investigative efforts, depending on how they are counted.

The report says Project SIGN evaluated 243 reported UFO sightings.

The report says the U.S. Air Force recorded 12,618 UFO sightings between 1947 and 1969 in connection with Project Blue Book.

The USAF recorded 12,618 UFO sightings between the years 1947-1969.

Of the 12,618 Project Blue Book sightings, the report says 701 remained categorized as unidentified and unsolved.

Of the 12,618 sightings in Project BLUE BOOK’s holdings, 701 were categorized as unidentified and never solved.

The report characterizes the debris recovered near Roswell as consistent with a balloon used by the then-classified Project Mogul and says records showed no recovered aliens or extraterrestrial material.

the materials recovered near Roswell were consistent with a balloon of the type used in the then-classified Project Mogul. No records showed any evidence that the USG recovered aliens or extraterrestrial material.

AARO distinguishes AAWSAP from AATIP, stating that AATIP was never an official Defense Department program and later referred to an informal UAP community of interest.

Unlike AAWSAP, AATIP was never an official DoD program.

The report says AAWSAP/AATIP investigated alleged UAP and paranormal activity at a Utah property, including remote viewing and human-consciousness claims.

AAWSAP/AATIP also investigated an alleged hotspot of UAP and paranormal activity at a property in Utah—which at that time was owned by the head of the private sector organization

The report says the UAP Task Force helped standardize and destigmatize reporting, increased reporting volume, improved sensor calibration, and aided identification of Chinese high-altitude balloons.

The UAPTF helped standardize, destigmatize, and increase the volume of UAP reporting. Its work also helped calibrate sensors to improve the quality of data collected.

AARO reports that a small percentage of its cases have potentially anomalous or concerning characteristics and says its research on those cases continues.

A small percentage of cases have potentially anomalous characteristics or concerning characteristics. AARO has kept Congress fully and currently informed of its findings. AARO’s research continues on these cases.

AARO reports that an alleged 1961 Special National Intelligence Estimate about UFOs and nuclear threats is not authentic.

AARO concluded the document is not authentic.

AARO says KONA BLUE was never approved or established as a special-access program and that no data or material were transferred to the Department of Homeland Security.

The SAP was never approved or stood up, and no data or material was transferred to DHS.
