See what would settle it. ## Where it stands Three answers have been proposed. None is ahead on the evidence yet. Three are still possible. ## Why it matters The UFO strand of the story, the "reverse tech" idea, needs two things: that such a programme exists, and that someone on the list worked on it. The first is the subject of the site's mystery on US government UAP disclosures, whose question "Does the US government hold recovered non-human craft or materials, as witnesses have testified?" (https://mysteriesdept.com/r/QST0CXDNKG005SN) weighs Grusch's testimony against the Pentagon's historical review⁠[[1]](https://mysteriesdept.com/sources/SRC0CXDN62A7S39/opening-statement-to-the-house-oversight-subcommittee-on)⁠[[2]](https://mysteriesdept.com/sources/SRC0D0140M03414/report-on-the-historical-record-of-u-s-government). This question asks only the second part, and what the record shows of McCasland's own link to UFO work⁠[[3]](https://mysteriesdept.com/sources/SRC0DCQC4JZ7ZZM/missing-retired-air-force-general-consulted-on-ufos-for)⁠[[4]](https://mysteriesdept.com/sources/SRC0DCQCD2NPV32/read-tom-delonges-leaked-email-to-hillary-clinton-campaign). ## Answers 3 [**No: no such programme is documented, and no one on the list is documented as working on one** ](https://mysteriesdept.com/mysteries/missing-scientists/answers/ANS0DCQPP8B3QZ1/no-no-such-programme-is-documented-and-no-one-on-the-list-is) None Evidence: 2 for Still possible [**None of these.** ](https://mysteriesdept.com/mysteries/missing-scientists/answers/ANS0DCQPQ0CJG90/none-of-these) None Evidence: none yet Still possible [**Yes: such a programme exists, and McCasland, at least, was close to it** ](https://mysteriesdept.com/mysteries/missing-scientists/answers/ANS0DCQPPJRTBTW/yes-such-a-programme-exists-and-mccasland-at-least-was-close) None Evidence: 2 for, 1 against Still possible ## What would settle it 1. Watch for releases under the UAP records provisions and any further FOIA release by the DoD Inspector General of Grusch's submissions (withheld in full under DODOIG-2024-000205), and record whether any names a retrieval programme or anyone on the list. ## History 1. 2013[U.S. Air Force: deLonge wrote in 2016 that McCasland had run the laboratory where the Roswell wreckage was taken](https://mysteriesdept.com/sources/SRC0DCQCC8Q9PKP/major-general-william-n-mccasland)For: Yes: such a programme exists, and McCasland, at least, was close to it 1. 2016[Blistein: deLonge wrote in 2016 that McCasland had run the laboratory where the Roswell wreckage was taken](https://mysteriesdept.com/sources/SRC0DCQCD2NPV32/read-tom-delonges-leaked-email-to-hillary-clinton-campaign)For: Yes: such a programme exists, and McCasland, at least, was close to it 1. 2023[Grusch: grusch testified under oath that he was told of a multi-decade retrieval and reverse-engineering programme](https://mysteriesdept.com/sources/SRC0CXDN62A7S39/opening-statement-to-the-house-oversight-subcommittee-on)For: Yes: such a programme exists, and McCasland, at least, was close to it 1. 2024[All-domain Anomaly Resolution Office: the Pentagon's 2024 historical review found no verifiable evidence of a retrieval or reverse-engineering programme](https://mysteriesdept.com/sources/SRC0D0140M03414/report-on-the-historical-record-of-u-s-government)For: No: no such programme is documented, and no one on the list is documented as working on one 1. 2024[All-domain Anomaly Resolution Office: the official historical review found no verifiable evidence of the programme](https://mysteriesdept.com/sources/SRC0D0140M03414/report-on-the-historical-record-of-u-s-government)Against: Yes: such a programme exists, and McCasland, at least, was close to it 1. 2026[Ruiz: mcCasland's documented UFO link is unpaid advice to DeLonge's fiction and media projects](https://mysteriesdept.com/sources/SRC0DCQC4JZ7ZZM/missing-retired-air-force-general-consulted-on-ufos-for)For: No: no such programme is documented, and no one on the list is documented as working on one 1.
