From Blue Book to AARO: Decades of U.S. UAP Scrutiny and the Push for Disclosure (1947–2024)

Investigation of UFO reports by the United States government - Wikipedia

Since 1947, the U.S. has systematically studied unidentified aerial phenomena across multiple agencies—from Project Sign/Grudge/Blue Book and the Robertson Panel to the Condon Report and congressional hearings, then renewed scrutiny starting in 2017 with AATIP, the UAPTF, NASA and the All-domain Anomaly Resolution Office (AARO) in 2022, public disclosures of videos, and high-profile testimonies by Avi Loeb, David Grusch, Ryan Graves, and David Fravor (with Scott Bray and Ronald Moultrie among those testifying), ongoing legislation such as the Unidentified Anomalous Phenomena Disclosure Act and an August 2023 public UAP portal, culminating in a March 2024 AARO assessment that found no evidence of extraterrestrial spacecraft but attributed most cases to misidentifications or ordinary objects, all within a framework emphasizing better data collection and declassification amid persistent public and congressional pressure and disputed claims of alien technology, while figures like J. Allen Hynek helped shape earlier scrutiny.
