The report states that AARO found no empirical evidence for claims that the USG or private companies have recovered, hidden, or reverse-engineered extraterrestrial technology or biological material. It notes that many claims trace to circular reporting within a small group of individuals linked to earlier UAP programs like AAWSAP/AATIP. Specific allegations, including those involving 'non-human biologics' or crash retrievals, were investigated; programs such as the proposed KONA BLUE (a Prospective Special Access Program for potential UAP material exploitation) were never formally established, received no funding or materials, and assumed the existence of such items without evidence. A sample claimed to be from an off-world craft was analyzed and determined to be a terrestrial magnesium-zinc-bismuth alloy. Overall, no U.S. government investigation has confirmed any UAP as extraterrestrial technology; most sightings were explained as misidentifications or ordinary phenomena. The report explicitly addresses and finds inaccurate specific claims of hidden programs or recovered biologics.[[1]](https://s3.dualstack.us-east-1.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-615/493468580/05_AARO_Historical_Record_Report.pdf)[[2]](https://en.wikisource.org/wiki/Report_on_the_Historical_Record_of_U.S._Government_Involvement_with_Unidentified_Anomalous_Phenomena)[[3]](https://uapledger.com/documents/aaro-historical-record-volume-1)
