A Pentagon report on Unidentified Anomalous Phenomena (UAP) concluded that there is no evidence the US has reverse-engineered alien spacecraft. The long-awaited report also rebutted claims that the US is hiding technology or extraterrestrial biological material.The first volume of a probe from the All-domain Anomaly Resolution Office (AARO) called the Historical Record Report, was released on March 8. The ARRO is a US government office established in 2022 to detect and mitigate threats including “anomalous, unidentified space, airborne objects.” The ARRO probe debunks claims of alien or unexplainable UAP, more commonly known as UFOs.
