# Report on the Historical Record of U.S. Government Involvement with Unidentified Anomalous Phenomena/Volume 1/Section 3

Layout 2
​SECTION III: Scope & Assumptions
Scope
This HR2 is provided by DoD in response to a requirement established in the National Defense Authorization Act (NDAA) for FY 2023, Section 6802(j), which states: "Not later than 540 days after the date of the enactment of the Intelligence Authorization Act for Fiscal Year 2023, the Director of the Office shall submit to the congressional defense committees, the congressional intelligence committees and the congressional leadership a written report detailing the historical record of the United States Government relating to unidentified anomalous phenomena." This report, pursuant to the legislation, is based upon the records and documents of the IC and DoD, oral history interviews, open source analysis, interviews of current and former government officials, and classified and unclassified archives.
AARO will provide its findings to Congress in two volumes:
AARO interviewed approximately 30 people who claimed to have insight into alleged USG involvement in off-world technology exploitation or to possess knowledge of UAP that have allegedly disrupted U.S. nuclear facilities in the past.
Assumptions
AARO and DoD assume that individuals convey their accurate recollection of their perception of the events they observed or heard. It is important to note that AARO cannot discount nor rely on interviewee accounts alone because of the extraordinary claims contained in their reports. Although individual accounts are important, they are only one element of the larger picture and provide AARO with the opportunity to initiate an investigation. However, any final assessment on the veracity of these accounts must be accompanied by provable facts.
Note on "UAP" Nomenclature
Use of the UAP naming convention, while imperfect, is the best manner in which to characterize the multitude of unidentified reported sightings. AARO understands that the use of "UAP" to refer to all potential possibilities provides a false sense of commonality; such as their origins, identity, purpose, type, and threat they may pose. The only commonality that they all share, at least initially, is that they are each unidentified. Beyond initially being unidentified or misidentified, drones, balloons, aircraft, rockets, rocket exhaust plumes, satellites, infrared (IR) aberrations, sensor artifacts, birds, stars, planets, indistinct lights, vague radar returns, meteors, and optical effects—such as parallax—have nothing in common.
Congressional Oversight
DoD is committed to providing timely and thorough reporting to Congress and to transparency with the American public. Since its establishment, AARO has endeavored to keep Congress fully and currently informed of its activities and findings at all levels of classification. AARO and DoD will continue to share the status and findings of its research at the appropriate level of classification with Congress.
AARO's HR2 Program of Analysis
AARO established six complementary lines of effort (LOEs) to conduct the HR2 research with the goal of ensuring this report conveys an accurate and complete picture. LOEs were conducted in parallel and reinforced each another; a lead in one LOE drove new research and pursuits in another. AARO's goal was to conduct thorough cross-checks to vet all information to discover and close gaps in its understanding. These LOEs were to:
