Non-Human Craft Recovery Programs is the collective term for a body of allegations asserting that the United States government and associated private defence contractors have, over several decades, retrieved physical craft assessed to be of non-human origin, stored them at secure facilities, and conducted efforts to reverse-engineer their technology. The claims emerged from multiple independent streams of testimony, government whistleblower disclosures, and journalistic investigation, but have not been confirmed by any official US government body. The All-Domain Anomaly Resolution Office (AARO) concluded in its 2024 Historical Record Report that it found no empirical evidence supporting the core allegations.1920
The most prominent public disclosure came from David Grusch as part of the Grusch Unidentified Anomalous Phenomena (UAP) Whistleblower Disclosure, 2023. In testimony before the House Oversight Subcommittee on 2023-07-26 and in classified submissions to Congress beginning in 2022, Grusch stated that he had been informed in the course of his official duties of a multi-decade UAP crash retrieval and reverse-engineering programme to which he was denied access.1 He described what he characterised as a decades-long covert competition with near-peer adversaries to identify Unidentified Anomalous Phenomena crash and landing sites and retrieve material for exploitation, aimed at gaining asymmetric national defence advantages.4 Grusch asserted that retrieved objects had been assessed as of exotic non-human origin on the basis of vehicle morphologies, material science testing, unique atomic arrangements, and radiological signatures,3 and that the government, its allies, and defence contractors had made recoveries ranging from partial fragments to intact vehicles across several decades.2 He further stated that the operation had been illegally shielded from proper Congressional oversight5 and that recovery operations were ongoing at various levels of activity at the time of his testimony.22 Several current members of the alleged recovery programme reportedly corroborated Grusch’s account to the Intelligence Community Inspector General office.6 Grusch also testified that biologics recovered alongside some craft were assessed as non-human by individuals with direct programme knowledge.18
Prior to Grusch’s 2023 disclosure, a number of former officials and researchers had made or corroborated related claims. Eric Davis, a physicist with ties to government advisory bodies, told The New York Times in 2020-07 that the US held recovered physical UAP samples that examination had failed to explain, adding “We couldn’t make it ourselves,"12 and separately stated that in 2020-03 he had given a classified briefing to a Department of Defense (DoD) agency regarding retrievals from “off-world vehicles not made on this earth."13 The Wilson Davis Memo, a disputed document purporting to record a 2002 meeting between Admiral Thomas Wilson and Eric Davis, states that a secret programme had “recovered technological hardware not of this Earth and not made by human hands."17 Nat Kobitz, a former Director of the US Navy’s Science and Technology Development, confirmed to journalist Ross Coulthart that he had been read into a crash retrieval programme and had never been read out of it,14 stated he had heard the US had recovered alien spacecraft on several occasions,15 and confirmed the US had been attempting to develop recovered alien technology.16
Luis Elizondo, a former senior DoD intelligence official, recounted that his team was informed a defence contractor was in possession of UAP materials of non-human origin.7 When Jay Stratton enquired on the team’s behalf, the contractor acknowledged holding the material8 but stated that access would require authorisation from the Secretary of the US Air Force.9 Elizondo concluded this acknowledgement demonstrated the US Air Force had known about crash retrievals and historically controlled them.10 The contractor also indicated that after decades of study it could no longer glean meaningful understanding from the material and considered it an expensive liability.11 Christopher K. Mellon separately stated that multiple well-placed current and former officials had shared detailed information with him regarding an alleged non-human craft recovery programme, including insights into its governing documents and the location where a craft was allegedly abandoned and recovered. Intelligence analyst Jonathan Grey stated that retrievals of this kind are not limited to the United States and represent a global phenomenon.23 Whistleblowers also briefed members of Congress and their staff at the classified level about UAP Legacy Programs efforts to capture, collect, and reverse-engineer vehicles of non-human origin.24
AARO’s 2024 Historical Record Report characterised the overarching claim — that the US government and industry partners have possessed and concealed off-world technology from Congressional oversight since approximately 1964 — as the dominant narrative it had been tasked to investigate.21 AARO concluded that many programmes alleged to relate to UAP exploitation are authentic sensitive national security programmes, but that none had been involved with capturing, recovering, or reverse-engineering off-world technology.20 The office stated it had found no empirical evidence that any UAP investigatory effort since 1945 had uncovered verifiable information regarding the recovery or existence of extraterrestrial craft or beings.19 Proponents of the recovery narrative, including Grusch and Elizondo, have argued that the relevant programmes were deliberately concealed from AARO and other oversight bodies, a claim that remains contested and unresolved in the public record.
