Defense Intelligence Agency (DIA) · Initiating and managing the Advanced Aerospace Weapon System Applications Program (AAWSAP) · DIA scientist and rocket engineer

James Lacatski is a Defense Intelligence Agency (DIA) scientist and rocket engineer who initiated and managed the Advanced Aerospace Weapon System Applications Program (AAWSAP) for the Defense Intelligence Agency (DIA).1 He holds a doctorate in engineering and was described as one of the government’s top rocket scientists.2 According to Lacatski, the programme was nestled inside the DIA, a member of the US intelligence community, and drew its authority directly from the United States Congress.3 It was supported by then-Director of the DIA Lieutenant General Michael D. Maples, and funded through the efforts of Senator Harry Reid (Democrat, Nevada), Senator Ted Stevens (Republican, Alaska), and Senator Daniel Inouye (Democrat, Hawaii).4

Lacatski described AAWSAP to Luis Elizondo as a programme that focused on unusual phenomena and investigated unidentified aircraft displaying beyond-next-generation technology and capabilities, now termed Unidentified Anomalous Phenomena (UAP), previously known by the term Unidentified Flying Object (UFO).5 He told Elizondo that for decades civilians, military personnel, and law enforcement officers had reported strange sightings across the world, supported by data from the same intelligence-gathering systems used to protect national security.6 Lacatski maintained that the phenomena under study did not conform to physics as currently understood.7

Elizondo first met Lacatski at a government office building on the tenth floor in Virginia.8 Lacatski formally asked Elizondo to handle counterintelligence and security for AAWSAP,9 telling him the programme worked on sensitive aviation technology and needed a senior counterintelligence agent to protect its intelligence from foreign adversaries.10 Jay Stratton and Lacatski briefed Elizondo on AAWSAP and its successor, the Advanced Aerospace Threat Identification Program (AATIP), inside a Sensitive Compartmented Information Facility (SCIF).11 At Lacatski’s suggestion, Elizondo used his government computer to search terms including “unknown technology”, “unusual performance”, “anomaly”, “unidentified”, “UFO”, and “UAP”.12

According to Elizondo, Lacatski and his team pursued the investigation of anomalous phenomena at USA, Utah, Skinwalker Ranch because the science warranted further investigation and they could not rule out a link between the events there and UAP.13 Elizondo said Lacatski believed the research at Skinwalker Ranch was worth pursuing.14 The book In Plain Sight (2021) reports that around 2008, Senator Reid received a letter from a senior DIA scientist - likely a physicist named James Lacatski, though he was never publicly named - whose world view had been transformed by events he witnessed at the ranch.15

As Lacatski and his contractors circulated AAWSAP executive summaries, the email responses received via secure internal servers were unfailingly positive.16 That changed with a shift in DIA leadership: within weeks, Lacatski began spending most of his time defending his efforts rather than conducting research, as senior DIA leadership actively tried to kill the programme.17 If any glimmer of the truth about Lacatski’s work reached a broader report destined for other powerful readers, DIA bureaucrats killed it, filed it away, or ignored it.18 Within thirty to forty-five days of Devon Woods’s reassignment to the DIA, the agency’s attitude toward AAWSAP shifted, with higher-ups who had previously welcomed the reports beginning to question why the work was being done.19 In the fall of 2009, Elizondo and Jim Semivan attended a meeting with Lacatski in which they discussed whether AAWSAP should drop investigations widely considered paranormal and instead focus solely on UAP threats.20 Elizondo said that in the spring of 2010, Lacatski confided to him that he was being pressured to stop all AAWSAP efforts.21 Lacatski planned to meet with Deputy Secretary of Defense William J. Lynn that year in an effort to allay concerns about the programme.22 George Knapp has said that when Lacatski pressed for access to the exotic materials studied under AAWSAP, he was met with harsh rebukes and had the door slammed in his face.23 Elizondo called Michael Higgins and asked him to protect Lacatski from internal persecution within the DIA;24 Higgins agreed and said he would look into it.25 Elizondo believed that, as the newest member of the AAWSAP/AATIP team, the powers that be had targeted Lacatski and the programme for elimination.26

Lacatski also conceived a chart placing the word God at the top, Angels in the middle, and Humans at the bottom.27 According to Elizondo, he theorised that if the distance between humans and angels is large, an entire ecosystem of divine and semidivine life forms could exist between purely spiritual angels and flesh-and-soul humans.28 A briefing Lacatski prepared for DIA and United States Department of Defense (DoD) leadership included the terms archangels, angels, demons, and spiritual realm.29 Elizondo has said that Lacatski and his team ran the United States’ official programme on UAP, while the Legacy Program worked at cross-purposes to that effort.30 Jim Lacatski has also been identified as a DIA rocket scientist who was involved in AAWSAP,31 and Jesse Mitchells has said that Lacatski writes about the UFO subject as a platonic puzzle, more a mystical object than something physicists would be set against.32
