1. "NASA's Spin-Coupled Force Experiments" (Tim Ventura, 16 May 2026)

URL: https://www.altpropulsion.com/nasas-spin-coupled-force-experiments/ [web] - A long popular account of NASA TM-20205010911 (POAMS), which is already in the project folder. It adds no new primary data; its facts match the TM (SAA signed 1 July 2015; V3 bismuth rotor test 7 Oct 2016 with R. Eskridge, M. Nelson, C. Milam present; about 0.3 g loss/gain, 211 g rotor, about 0.14%; effect faded and returned with new magnets; V5 data held by Quantum Machines; no further NASA work after QM stopped funding) [web]. - New to the review: it states the author found "no public Eskridge patent explicitly covering POAMS, spin-coupled force, bismuth rotors ... gravity modification" [web]. It lists the null gyroscope replications (Quinn and Picard; "Gyroscope-weighing experiment with a null result") against Hayasaka-Takeuchi 1989 [web]. - Bears on claim 3 (spin alignment and weight).

2. "Mark Sokol: Anti-Gravity with Present Technology" (Tim Ventura, 21 Apr 2026)

URL: https://www.altpropulsion.com/mark-sokol-anti-gravity-with-present-technology/ [web] - Identifies the New Jersey lab: Falcon Space, Hawthorne, New Jersey, CEO Mark Sokol, which "works closely with the Alzofon estate" (David Alzofon) to recreate Frederick Alzofon's dynamic nuclear orientation (DNO/DNP) weight-reduction result [web]. This is very probably where the 28 May 2020 "Alzofon experiment" in the interview was to be run (inference; the article does not mention 2020 or Amy). - Hardware: an S-band (about 3 GHz) DNP machine with vacuum and liquid-helium cryogenics attributed to George Hathaway and Daniel Alzofon, never completed on its ruby sample; an X-band system in a Faraday cage under LabVIEW control [web]. - Sokol's claim (his characterization): with the sample at a field "saddle point", "a positive correlation between Dynamic Nuclear Polarization and changes in sample weight over multiple runs"; a paper with David Chester presented as a poster at the Asilomar Experimental NMR Conference (ENC) [web]. No data or poster text found (Google query for the poster returned nothing). - 2026 direction: triplet-state DNP with a tunable laser, Bridgman crystal growth, nitrogen-vacancy diamonds (to orient carbon nuclei) [web]. - The article cites Alzofon AIAA 81-1608, Alzofon's Physics Essays paper, AAS 59-022, the book "How to Build a Flying Saucer and Save the Planet" (F. and D. Alzofon), Stark/Grafe/Tajmar (Measurement), Tajmar/Kossling/Neunzig (Scientific Reports, steady-field coupling search), and David Prutchi's critique "F. Alzofon's 1994 experiments DO NOT prove his model of gravity" [web]. - The article names "Dr. Richard Eskridge" as part of the same "unconventional-propulsion ecosystem" around Sokol [web]. - Bears on claim 3 (Alzofon/DNO test planned in 2020) and on claim 4 (Tajmar's null results are the main counter-record).

3. "Superconductors & Gravity Control: A 30-Year History" (Tim Ventura, 9 Jul 2025)

URL: https://www.altpropulsion.com/superconductors-gravity-control/ [web] - Summary of an interview with Gary Stephenson. Points that bear on claims 1, 2 and 4: - Ron Koczor described as program manager of a NASA program that funded Ning Li; NASA's attempts to replicate Podkletnov "were unsuccessful, largely due to difficulties in replicating the precise experimental conditions" (as stated by Glen "Tony" Robertson) [web]. - Closing summary: Tajmar's replication negative; "Claude Poher attempted a replication and claimed positive results"; "NASA, it turns out, never completed their replication attempt at all, despite rumors to the contrary" [web]. Context is the 1990s-2000s Podkletnov rotating-disc replication, not the 2015 Poher-type test Amy described; the two should not be conflated. - Lists "Amy Eskridge, Claude Poer [sic], and Mark Sokol" as contemporary contributors [web]. - In 2025 Glen Robertson (an adviser on the Institute's 2018-2019 website) "is beginning work on a new replication attempt" with volunteers [web]. - Related: the Google snippet for "Gravity-Superconductors interactions: Theory and experiment" (the Modanese/Robertson book cited on the Institute site) and a NASA Breakthrough Propulsion Physics document (computationaldemonology.com) saying a privately funded Podkletnov replication was completed by Hathaway and that "Tony Robertson, NASA MSFC, Final report due 2001" [web: Google snippet only, not opened].
