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

The report concludes that AARO found no empirical evidence that the U.S. government or private companies have been reverse-engineering extraterrestrial technology. It determined that claims involving specific people, locations, tests, and documents allegedly related to the reverse-engineering of extraterrestrial technology are inaccurate. Interviewees' accounts of hidden programs were assessed as either nonexistent, misidentified legitimate national security programs unrelated to extraterrestrial technology, or resolved to unwarranted and disestablished efforts. Specifically on KONA BLUE, a proposed Prospective Special Access Program identified by interviewees as intended to cover retrieval and exploitation of non-human biologics, AARO found it was never approved, established, funded, or provided any materials; it was rejected by DHS leadership for lacking merit, with the assumption of extraterrestrial craft or bodies existing only as a premise among advocates. No verifiable evidence of recovered extraterrestrial craft or biologics was located across reviewed records, interviews, and archives. A sample alleged to be from an off-world spacecraft was analyzed and determined to be a terrestrial manufactured alloy.
