35-page slide deck for a talk to the Huntsville Alabama L5 Society (HAL5), 6 Dec 2018 (pp.1-4 title and speaker material; pp.5-35 content). It is a survey of 'gravity modification' history, not a statement of the Institute's own mechanism: definitions (gravity, 'antigravity', relativity needs negative mass, graviton unsolved), then early efforts (T. T. Brown electrogravitics, Tesla patent 1,655,144, Gravity Research Foundation 1948 and the 1953 DeWitt essay, supposed 1950s Wright-Patterson work, Searl, Dean, Wallace 1968 'kinemassic field', Laithwaite gyroscopes 1974), the Mansfield Amendment (1973), the Hutchison effect, Woodward/Mach effect (1990), and modern efforts in Huntsville and elsewhere: Ning Li and Doug Torr (UAH, AC Gravity LLC 1999, $500,000 DoD contract 2001), Podkletnov (rotating YBCO disc, 2001 patent, claimed 2% weight reduction), Torr/Vargas/Datta (USC, 2001), Poher (static YBCO disc discharge, 'tested at NASA MSFC, 2015'), Morningstar Applied Physics (claimed 7%), Boeing Phantomworks GRASP ('admitted to in 2014'), and the Dec 2017 AATIP/DIA reference documents. The conclusion slide (p.34) says: theories with a testable hypothesis are needed; independently funded private research is required; 'Promising results always disappear into the classified realm - how do we fix this?'. The deck has no reference list, no URLs and no citations; sources appear only as images (a Reddit screenshot on p.25, patent drawings, a Popular Mechanics photo, book covers, DIA document covers). Many slides are hedged ('supposedly', 'claimed', '?'); some carry verdict labels ('unsubstantiated' for Brown's 1960 patent and Wallace, 'Widely panned' for Searl and Podkletnov, friction for Dean, Newton's 2nd law for Laithwaite). The Ning Li slide (p.25) rests its 'disappearance' on an anonymous r/conspiracy post. The Boeing slide poses every bullet but the program name as a question. She is an interested party (her Institute pursues this R&D); the deck is her characterization of others' work. Small slips are on the slides themselves: Cavendish dated 1790s (usually 1797-98), Podkletnov 'ousted by University of Tampere (1997)' with no source, slide p.28 says Torr's work 'never made public' while p.26-27 show a patent figure and a website 'still online'. QE addendum (2026-10-07, page images pp.10-12): slide p.12 reads 'Patent 1,655,144: a "space drive" or anti-electromagnetic propulsion system' beside the cover of William Lyne's 'Occult Ether Physics' (a popular book by an author with a stake in its thesis); p.11 is an unlabelled saucer cutaway with no patent number. Checked: US 1,655,144 is a 1928 grain-treating machine (Hallgarth and Chandler), not a Tesla patent [web: https://patents.google.com/patent/US1655144A/en]. Tesla's 3 Jan 1928 aircraft patent is US 1,655,114 'Apparatus for Aerial Transportation', a vertical-take-off 'helicopterplane' driven by turbines [web: https://patents.google.com/patent/US1655114A/en]. So the number on her slide is wrong whichever Tesla patent was meant, and no Tesla patent in that family describes a space drive; the slide's characterization comes from the Lyne book, not the patent. The number is hers (as shown on her slide); the book is the likely origin (not confirmed).

Key claims

• Antigravity ('gravity modification') is not allowed by general relativity without negative mass, and the Standard Model has no negative mass (p.7).
• A rotating YBCO superconductor produces 'gravity shielding' with a claimed 2% weight reduction (Podkletnov, 2001 patent; p.26).
• Ning Li and Doug Torr (UAH) theorized that a magnetic field on a superconductor aligns ion spins to give gravitomagnetic and gravitoelectric effects; AC Gravity LLC was founded 1999 and got a $500,000 DoD contract in 2001 (p.24).
• Claude Poher's static YBCO disc, discharged, gives a propelling force; it was 'tested at NASA MSFC, 2015' (p.29; the transcript adds that her father ran that test).
• Morningstar Applied Physics claims a 7% weight reduction with a modified Searl machine (p.30).
• The 1973 Mansfield Amendment means 'most modern antigravity research has been outsourced to the private sector (and/or black budgets)' (p.21).
• Boeing Phantomworks ran a Gravity Research for Advanced Propulsion (GRASP) program 'admitted to in 2014' (p.31; no source given).
• Antigravity needs theories with testable hypotheses and independently funded private research, because 'promising results always disappear into the classified realm' (p.34).

Relevance: Only primary Amy Eskridge document with a formal structure: shows what she presented publicly as the field's history and what she treated as credible (Podkletnov, Poher, Li) or as unsubstantiated (Brown 1960 patent, Wallace). It names the 2015 MSFC Poher-type test, the thread that links her to her father's NASA work.

Mainstream conflict: Mainstream physics holds that no antigravity or gravity shielding effect exists; the deck itself labels several items 'unsubstantiated' or 'widely panned'. The slides present the suppression and black-budget readings as consequences ('This means...') while the lecture presents them as one of several interpretations. Whether Podkletnov's effect was tested and failed or never properly tested is not addressed in the deck. Slide p.12's Tesla 'space drive' patent number does not match a Tesla patent (see summary).

HAL5 announcement: 'A Historical Perspective on Anti-Gravity Technology', Thursday 6 December 2018, 7 pm, Huntsville-Madison County Main Public Library auditorium, speaker Amy Eskridge, President and Co-founder of The Institute for Exotic Science. The abstract defines antigravity as hypothetical positive or negative modification of gravity, with a timeline from Brown's Gravitator (1920s) to the EM Drive (early 2000s). Her bio: chemistry degree from UAH, enrolled in the UAH Materials Science PhD program, MEMS testing of piezoelectric microcantilevers and gyroscope testing, nonviral polymeric drug delivery and gene therapy work, software consulting and startup leadership, co-founder and President of the Institute (a public benefit corporation) and CEO/President of HoloChron Engineering. The page copyright line shows it was updated in 2024.

Key claims

• Amy Eskridge gave the talk 'A Historical Perspective on Anti-Gravity Technology' at the Huntsville library on 6 December 2018.
• Her self-described credentials in 2018: UAH chemistry degree, Materials Science PhD student, President of the Institute for Exotic Science, CEO of HoloChron Engineering.

Relevance: Dates and fixes the lecture and gives her self-reported credentials (an interested party's own biography).

Mainstream conflict: none

YouTube machine captions of what is most likely the 6 Dec 2018 HAL5 talk (the header says 'not confirmed'); it follows the slides and then runs a long Q&A. Speakers are not separated and names are garbled (for example 'Pod Like Knobs' for Podkletnov, 'Naimly' for Ning Li, 'Boyer' for Poher, 'Ivar' for Vargas), so audience statements can be mistaken for hers. The deep read sorts statements into her slide summary, her own testimony, her hearsay and audience claims. Beyond the slides: (1) She says anti-gravity is a misnomer, 'really more gravity modification' [00:00:45]. (2) Poher/2015 test: 'tested at NASA Marshall Space Flight Center in 2015, which has not been published. My dad did that', very similar results, a discharge makes the liquid-nitrogen dewar explode but the disc is undamaged [00:29:08-00:30:10]. An unnamed first-person voice (possibly her father or another MSFC participant; not identified in the text) adds: glass dewars were destroyed so Walmart buckets were used; a fiberglass rod with an accelerometer read an 'excess of 500 Gs' but 'we never reproduced the waves that he claimed'; a levitated magnet over a second superconductor was thrown 'far away'; with a double Faraday cage 'we did not reproduce Boyer's signals'; a 1,000,000 frames per second film showed a wave; the disc was 'pristine' [00:49:38-00:52:44]. Her own summary (very similar results) and the first-hand voice (signals not reproduced) are both kept; the text does not reconcile them, and no control run is described. (3) Ning Li: three or four stories she has heard (cancer from toxic chemicals, died in China, absorbed by DoD, went to China for funding); 'I don't know what happened'; AC Gravity LLC 'still registered. But no one really knows what they're doing'; audience says big discs kept cracking and she reported no results beyond her paper, while another line says she reported a percentage reduction. (4) Podkletnov: smoke-vortex discovery story (hearsay), NASA MSFC collaboration c.2001 ended over unpaid travel (hearsay), claimed 2% weight reduction, 'a small number of labs have replicated or attempted to replicate with varying degrees of success' (no labs named); audience: a second experiment used a megavolt Marx generator in Moscow and 'they never would show a film'; alternative explanations raised (convection, nitrogen vaporizing). (5) She met Woodward at Estes Park (Sept, year not stated; probably 2018): 'he only ever gets like a micronewton of thrust'. (6) She photographed every page of Robert Becker's UAH quantized-gravity thesis; loan record: checked out twice, in 1999 by 'DIA' (as transcribed) and by her. (7) Institute plan: public benefit corporation registered in Delaware, taking equity investment ('closing that right now'), a planned 100,000 sq ft facility, 'generous royalties' to inventors; money, not technology, is the problem. (8) 'I believe in the ether' [01:03:35]; recommends Ken Wheeler videos. (9) Suppression framing: academia calls it fringe, tenure pressure suppresses publication, 'promising signals always seem to disappear' (partly garbled); to an inventor afraid of disappearing: 'taking it to the public is better'. She flags rumours as rumours (Wallace 'went black' is 'unsubstantiated'; Hutchison anecdotes 'take that with a grain of salt'; Boeing TR-3B/ARV talk is rumor). QE additions (2026-10-07, text re-read): (10) YBCO priority story [00:19:51]: YBCO 'was actually invented out of UAH by a grad student and it was famously stolen by another university and patents it within like the next day'; asked who invented it, a voice answers 'It was Jim Ashworth' [00:28:36]. This is very probably Jim Ashburn of UAH, co-author with Wu, Torng and Chu of PRL 58, 908 (1987); the first sample was made by Torng on 28 Jan 1987 and tested next day by Ashburn and Wu [web: https://ethw.org/Milestones:Superconductivity_at_93_Kelvin,_1987; https://www.aps.org/publications/apsnews/200307/prl-2.cfm]. The 'stolen patent' claim itself is not checked; the Wu/Chu priority history is the record to read. (11) Becker: she says she photographed every page of Robert Becker's UAH quantized-gravity thesis and that its loan record shows a 1999 'DIA' interlibrary-loan checkout [00:21:58]; the 2018 Institute website lists a Robert Becker as 'Aerospace Engineering and Quantum Gravity Technical Advisor' [read: website 2018], so he is on her own advisory list. The loan record is a checkable library record, not seen. (12) First-hand MSFC voice, in order [00:51:12-00:52:13]: 'we told management about this but we never saw the waves that he claimed'; 'when we use a double Faraday cage, we did not reproduce Boyer's signals' (Poher is meant, per slide p.29); 'However, we did see a whole lot of really strange effects. Like the tossing of the magnet and forces coming off the disc'; the disc was unaffected, and 'if it was a thermal explosion between the layers of the disc, it would have destroyed the disc, but you pull it out and it was pristine'; 'a million frames per second movie of a wave coming off one of his emitters'. The 'pristine disc' is the voice's own argument against a mundane thermal cause; 'we told management' points to MSFC management records (a lead, not seen). The voice is unnamed; whether it is her father is not stated.

Key claims

• In 2015 NASA MSFC tested a Poher-type pulsed YBCO device; the results were unpublished, the dewar was destroyed, and the disc was undamaged; her father ran it (her statement, 00:29:39).
• In the MSFC test an accelerometer on a fiberglass rod read an 'excess of 500 Gs' but Poher's claimed waves and signals were not reproduced (unnamed first-hand voice, 00:49:38-00:52:44).
• A magnet levitated over a second superconductor was thrown away when the first superconductor was fired (unnamed first-hand voice, 00:50:09).
• Ning Li's company AC Gravity LLC is 'still registered' but its activity is unknown, and Li's fate is unknown to the speaker (00:17:14, 00:18:16).
• Podkletnov claimed a 2% weight reduction and a small number of labs replicated or tried to replicate with varying success (00:23:36).
• Woodward's Mach-effect thrusters give only about a micronewton (her statement from meeting him at Estes Park, 00:41:27).
• The Institute is a Delaware public benefit corporation seeking equity investment to fund a shared research 'sandbox' and a 100,000 sq ft facility (00:57:26-01:02:04).
• Independent private funding is needed because academia suppresses fringe results and promising work disappears into the classified world (00:36:51; 00:55:48).
• The first-hand MSFC voice says the discharged disc came out 'pristine', which it offers as evidence against a thermal explosion between the disc layers, and reports 'a whole lot of really strange effects ... forces coming off the disc' alongside the non-reproduction of Poher's signals (00:51:42-00:52:13).
• YBCO was 'invented out of UAH by a grad student' and the patent 'stolen by another university' (00:19:51); the name given in reply, 'Jim Ashworth' (00:28:36), is probably J. R. Ashburn of PRL 58, 908 (1987).

Relevance: Adds to the slides her own testimony about the father's 2015 MSFC test, the Institute's business model, her belief in the ether, and how she frames suppression.

Mainstream conflict: Gravity shielding and anomalous thrust from superconductors conflict with mainstream physics (conservation laws, equivalence principle); the 500 g accelerometer reading has no stated mass or control, so no thrust can be derived. Ether belief conflicts with relativity as normally taught. The lecture itself offers mundane alternatives (friction for Dean, centripetal forces for Laithwaite, convection or nitrogen vaporization for the smoke vortex).

Machine-captioned recording of a call, about May 2020 (an experiment date of 28 May and a Cyber Huntsville luncheon on 27 May are mentioned). The uploader captured only his output audio, so Jeremy Rys is silent; there are no speaker labels, so who says what is inferred from content (Mark's daughter, divorce and 'Amy took me to the airport' are Mark's; the Alzofon/'dynamic nuclear orientation' remarks and the neutron-beam design talk are an interviewer's). Both interviewers are interested parties in a planned 'disclosure' documentary; Amy is seeking funding and publication for her father's work; the call is partly drinking and joking. Content, in her account: (a) Disclosure plan: publish 'the paper' on arXiv/archive rather than a peer-reviewed journal, with simultaneous media (Tucker Carlson, a Netflix documentary) and three months of public visibility first; the paper was never published (per README). (b) Physics claims: her group has 'a mathematical equation' for six forces with antigravity the sixth force and a seventh 'energy into matter into energy'; no equation is shown; 'gravity chemistry'. (c) Her father Richard Eskridge, technical lead of the NASA MSFC advanced propulsion lab, saw an idea that a neutron beam needs aligned spins; an interviewer called that Alzofon's dynamic nuclear orientation; a test of the 'Alzofon' experiment is planned for 28 May in New Jersey with Amy to travel. (d) Tajmar: she and a business partner confronted Martin Tajmar at the 2018 Estes Park (Woodward Mach-effect) conference: his published protocol used monolayer YBCO, Podkletnov's used a bilayer, so null results are irrelevant; Tajmar said send samples; she did not; she says he is 'funded by the German Air Force to publish no results' (her inference). (e) Harassment account: 'they're gonna kill you'/rape threats (relayed, unnamed sources), three apartment break-ins with an ex-boyfriend (cut charger, window closed, headphones unplugged, drawer searched), a silver Lexus whose plate was swapped within about two minutes of her remark and which later appeared as an Uber, a 'Mana World Holdings Trust' $100 million offer she calls a Russian criminal gang gathering intel, 'handler' boyfriends who leave at six months, Bluetooth attacks with 'logs and live packet captures' (not shown), roofie incidents, and an estimate of 5,000 foreign agents in Huntsville (hearsay). She names no police report, photo or video; she names a cybersecurity contractor (ex-CIO of Northrop Grumman, unnamed) who said her stories match those of other women in technology. (f) 'NSA list of five' who independently discovered anti-gravity, from a source she calls a possible 'plant' (self-styled time traveller 'Dan Cooper'): Tesla, Podkletnov, a Milwaukee 'Han' relative, Ken Wheeler (whom she also calls a 'honey pot'), Cooper, and her father as the fifth. (g) Fringe passages: 'ultra terrestrials' from Hal Puthoff, 'P47/P52' future humans (speaker uncertain), '20 and backers', 'time traveling world-saving prophecy fulfilling' joke. (h) She cites team members as possible plants: Bill Dent and Seth Whale; the Institute's 2019 website lists Bill Dent as Senior Scientist and Seth Wahle as Cybersecurity Technical Advisor. (i) Background: biology/chemistry degrees, nearly finished a biotechnology PhD (she says a harassment case sabotaged it), 15-year-old first job at Redstone Arsenal's weapons sciences directorate, a December 2019 negotiation to sell a plasma-thruster patent to Maxar (from her calendar), COVID-19 from DEF CON September 2019. Digest errors to avoid: the digest's 'Alzheimer's experiment' is a mis-caption of Alzofon; the digest attributes interviewer speech to Amy. QE additions (2026-10-07, text re-read): (j) Attribution correction: the Tajmar passage [01:25:34-01:27:47] is in the first person ('chantelle and i ... sprung on him ... we have your paper right here in our backpack ... it says you used a mono layer not a bilayer'), so the monolayer/bilayer argument is Amy's. 'Chantelle' is probably Shantel Butler, whom she describes at 01:07:22 as 'chief research officer of geometric energy in calgary' with 'sam' as business partners; the 2018 website lists Shantel Butler as the Institute's research director [read: website 2018], so she is a possible second witness to the 2018 meeting at Estes Park. Only the 'funded by the german air force to publish no results' line follows an interviewer interjection and remains of uncertain speaker. (k) Father and Podkletnov: 'my dad tried to get me to replicate eugene's experiment when i was a junior in high school' [01:26:06] and 'in 2004 my dad tried to get me to do the podkletnov experiment for the science fair' [01:31:33]; her father's interest in Podkletnov dates from at least 2004 (her account). (l) Maxar: she reads from her Outlook calendar 'i was negotiating with maxar about selling them a plasma thruster patent on the 17th of december' [00:57:56; digest and QE give 2019]. The Investigator found US7808353B1 (plasmoid-thruster coil patent) assigned from NASA to Richard H. Eskridge on 2018-10-03 [web: https://patents.google.com/patent/US7808353B1/en]; the link between the two is a reasonable lead, not a stated fact (the transcript does not name the patent). It shows commercial activity by the family business and bears on the funding and IP explanations for the Institute's silence. (m) Austin investor and Hal [00:47:14-00:48:15]: 'my dad got poached by this weird ass investor ... out of nasa ... who lives in austin texas he's a real estate investor ... this investor brings hal to our house' (three visits; 'hal' is first-name only, probably Hal Puthoff [memory: medium]). The NASA memorandum says Nelson's Space Act partners included Austin, Texas [read: TM p.37]; Quantum Machines LLC (the TM's funder, CEO Chris Milam) is a candidate but the TM gives no location, so the identity is open. Bears on who funded and holds the V5 data (claim 3). (n) PhD 'court case' [02:05:28]: she says her biotech PhD was ended through 'a sexual harassment thing ... a really horrible court case', 'a fake vehicle of sabotage'; a court record would exist if the case was filed; not seen. (o) 'Prototypes melted down for scrap' [01:16:46]: cancelled NASA Huntsville hardware goes to divestment auction and is melted by scrap vendors; a generalization with no named device.

Key claims

• Amy Eskridge and her group have a mathematical equation that physically describes six forces of nature, with anti-gravity the sixth (00:20:50; no equation shown).
• Martin Tajmar's published YBCO protocol used a monolayer, whereas Podkletnov used a bilayer, so Tajmar's null results do not test Podkletnov's claim (01:26:06-01:27:09).
• A test of Alzofon's dynamic nuclear orientation experiment was planned for 28 May 2020 in New Jersey (interviewer's plan; Amy to travel; 02:10:02).
• A neutron beam could be formed by orienting nuclear spins with dynamic nuclear orientation (an interviewer's design idea, 00:17:47-00:19:50).
• She was threatened, surveilled and burgled over four to five years, escalating in the last 12 months (02:57:31); no police report or physical record is cited beyond claimed packet captures and the Uber app record.
• A silver Lexus's licence plate was changed in front of her and her ex-boyfriend within about two minutes of her saying she would photograph it (02:53:22-02:57:31).
• A source she doubts says the NSA has a list of five people who independently discovered anti-gravity and that her father is the fifth (00:30:44-00:34:21).
• Huntsville has an estimated 5,000 foreign nation-state agents among about 100,000 people (01:44:28; hearsay from unnamed 'people in the know').
• Prototypes at NASA Huntsville that worked the first time were cancelled and scrapped (01:16:15; generalization, no named case).
• She says she and 'Chantelle' (probably Shantel Butler, the Institute's research director) confronted Tajmar in 2018 with his protocol paper showing a monolayer where Podkletnov used a bilayer; the account is hers, first person (01:25:34-01:26:38).
• Her father tried to get her to replicate Podkletnov's experiment in high school and again for a 2004 science fair (01:26:06, 01:31:33), per her account.
• In December 2019 she was negotiating with Maxar to sell a plasma-thruster patent, per her calendar (00:57:56); possibly US7808353B1, assigned to Richard H. Eskridge in October 2018 (Investigator, [web]).

Relevance: Her fullest account, in 2020, of her plans, physics claims, suspicions and the harassment narrative; it is the only document that gives her view of the Tajmar null results and the planned Alzofon test.

Mainstream conflict: Physics: no equation or data given for a sixth force or antigravity; mainstream physics has no such force. Harassment and intelligence-agency claims are not physics and are unverifiable from the transcript; the P47/P52 and time-travel material is outside science. The Tajmar objection is a testable protocol point (monolayer vs bilayer), but the 'Tajmar publishes null results on purpose' claim is her inference.

Archived home page: 'Exotic science. Exotic results.' The Institute is a public benefit corporation researching exotic phenomena, with licensing, patenting and product development; categories are energy, quantum computing, material science, communications, with specific interests in efficient energy, metamaterials, electroceramics, quantum gravity and exotic matter. Staff listed: Amy Eskridge (President; UAH chemistry degree, UAH Materials Science PhD student, MEMS and gyroscope testing at AMRDEC on Redstone Arsenal), a creative director, Shantel Butler (research director; also Chief Research Officer of Geometric Energy Corporation and of HoloChron Engineering), Samuel Reid (government affairs, Geometric Energy), Richard Eskridge (Professor Emeritus, co-founder; 33 years at NASA MSFC), Glen A. Robertson (propulsion advisor), Paul Handy. This is a promotional page by an interested party; 'quantum gravity' and 'exotic matter' are named but no claim is stated.

Key claims

• The Institute is a public benefit corporation focused on exotic phenomena including quantum gravity and exotic matter (own description, 2018).
• Richard Eskridge, retired NASA MSFC scientist, is a co-founder; Glen Robertson (ex-MSFC) is a propulsion adviser.

Relevance: Documents the Institute's self-description and staff; the Geometric Energy team (Butler, Reid) appears in her 2020 interview as business partners.

Mainstream conflict: none (no technical claims)

Archived July 2019 page, rebranded: a privately held, independently run, for-profit research institution for 'tomorrow's space economy' (propulsion, materials, energy, communications). Staff: Amy Eskridge (President, Chairwoman, co-founder); Richard Eskridge (Lead Scientist, Research Director); Dick Reeves (Vice Chairman, COO); Paul Handy; Kathy Eskridge (Operations); Bud and Abigail Brown; advisers Jeff Thornburg, Jen Rae Wang (ex-NASA communications), Glen Robertson, Tim Pickens, Eva Blaisdell, Bill Dent (nuclear physicist, Senior Scientist), Seth Wahle (cybersecurity), Deborah Barnhart. Richard's biography: retired from NASA MSFC Dec 2016 as Chief Technical Advisor of the Propulsion Research Lab; his 18 years of research included 'investigation of superconductor impulse gravity generators', fusion and electric propulsion, and the Plasmoid Thruster (PT-1, patent 7808353 B1). Robertson's bio cites his book 'Gravity-Superconductors Interactions - Theory and Experiment'. Notable: the 2018 'public benefit corporation' wording became 'for-profit' here; Bill Dent and Seth Wahle, whom she calls possible plants in 2020, are listed as staff.

Key claims

• Richard Eskridge's MSFC work included 'investigation of superconductor impulse gravity generators' (own website biography; no NTRS report found per README).
• Richard Eskridge co-holds Plasmoid Thruster patent 7808353 B1 (as stated on the site).

Relevance: Only document tying her father to the Podkletnov-type work, supports her statement that he ran the 2015 test.

Mainstream conflict: none stated; 'impulse gravity generators' refers to the Podkletnov claim, which mainstream physics does not accept

Technical memorandum of work under a Space Act Agreement (SAA8-1519855, signed 1 July 2015) with Quantum Machines LLC, whose CEO Chris Milam requested and funded it and who thought POAMS might underpin an advanced propulsion system (an interested party). Amy is not named. POAMS (Pope and Osborne, Galilean Electrodynamics 2003, as cited) says a spinning body in orbit has a spin-modified gravitational constant, G-bar = (v*/v0) G, with v* = sqrt(2(ko plus or minus ks)/m) built from orbital and spin kinetic energies. NASA reinterprets it as keeping G fixed and adding a non-Newtonian 'spin-coupled force' (SCF), and extends it to any central force. Key result (28a): delta f = sqrt(FN^2 plus or minus (m vo^2/ro)(sp wp/ro)) - FN; a vector form (31) was found 'by inspection'. NASA's own cases say ordinary spins change weight by less than 1 part in 10^8, so 'no viable test' on Earth-scale spins. The deep read finds (28a) is an exact algebraic restatement of the POAMS postulate (units consistent), with postulates for the sum of energies, the NASA extension to all central forces, an ad hoc continuation (28b) past an imaginary root, a 'synthetic velocity' vs = ro wp, and an assumed r = ro. Experiments: orbiting gyroscopes (V1, V2) gave unusable data because of bearing friction. Bismuth rotor (V3) combining Barnett and Wallace effects: first test 7 Oct 2016 at MSFC, with Richard Eskridge, Mike Nelson and Chris Milam present, on a 0.01 g-resolution scale. Anti-spin mode lost about 0.3 g (possible thermal buoyancy or aerodynamic forces), then after a rebuild co-spin gained 0.3 g on a 211 g rotor (0.14%), described as 'a remarkable result' that 'matched the theory'; the effect weakened with repeated tests and disappeared, returned with new magnets, and was 'suspected' to come from the rare earth magnets. V4 and V5 (at QM, data held by QM) followed; no further MSFC work for lack of funding. Conclusion: 'rudimentary and preliminary data appears consistent' with the spin-coupled force, more careful work needed. No error bars, controls or published data tables appear in the sections read. Appendix A is Richard Eskridge's handwritten derivation, 16-24 September 2015. Wallace's 1971 patent 3,626,605 is cited, linking to the Wallace machine on her HAL5 slide 18. The report's date is 1 Nov 2021 (documentation page) while the back cover says April 2021. QE additions (text pp.25-36 re-read): (a) The V3 rotor, tested 7 Oct 2016 with Richard Eskridge, Mike Nelson and Chris Milam (QM CEO) present, used a cast bismuth disc with an aluminum outer shell (the V4 used a SS304 shell) spun by a three-phase motor; rotor dimensions, rpm, magnet geometry, number of runs and any control run (an inert rotor) are not given [read: TM p.33-35]. (b) Alignment mechanisms the TM invokes [read: p.31-33]: Barnett self-magnetization of electrons; Overhauser transfer from aligned electrons to nuclei ('as predicted by Overhauser'); a field gradient that 'induces a small fraction of the nuclei to flip parallel to the spin axis'; and the Wallace effect. All four are stated in words only; the TM gives no number for any of them, only the magnet field (2,000 gauss) and the remark that 'a very small alignment fraction' is implied. It also says 'in most ordinary situations, even for very high magnetic fields and cold temperatures the alignment fraction is limited to a very small fraction' and that 'significant improvements in nuclear alignment methods' are needed (p.30). So the memorandum itself supplies no figure that raises Bi-209 alignment above thermal equilibrium at 0.2 T and room temperature. (c) The authors' own control arguments, in their favour: 'a multiphase motor ... direction is controlled by relative phasing of the three pulsed DC signals ... does not have a reversal of DC current which might explain a reversal of forces' (p.33), and 'the external magnetic field of the magnets was measured from test to test and did not change' while the effect faded to nothing and 'returned with equal force' with new magnets (p.33). The memorandum itself raises thermal buoyancy or aerodynamic forces for the first 0.3 g loss and later suspects 'some phenomenon in the rare Earth magnets'. (d) Table 1 / Appendix B sign convention (QE correction): Appendix B defines Fmeas = Fgyro - DF, so the table's change is F_zero-spin minus F_table; with F_N = 89.85 N (disc mass) and that sign, Table 1 is reproduced by eq. 28a [calc by QE; earlier statements here and in the deep read that it is not reproduced are withdrawn]. (e) The V1/V2 orbiting-gyroscope runs: 'There were measurable deviations in centripetal forces ... but meaningful measurements of these anomalies could not be made because of the rapid spin-down' (p.25); V2 'data were not useful' (p.27). (f) The V5 and its data remain with QM; the Space Act proprietary period has ended and 'NASA may therefore continue the research' (p.35).

Key claims

• A spinning body in orbit experiences a non-Newtonian 'spin-coupled force' delta f = sqrt(FN^2 +/- (m vo^2/ro)(sp wp/ro)) - FN (eq 28a), equivalent to a spin-modified G (Pope-Osborne).
• The spin-coupled force applies to any central force, not only gravity (NASA's own assumption, p.16).
• The spin-coupled force can be produced by aligning nuclear spins (nucleons) in a spinning rotor in a magnetic field, giving a weight change.
• A 211 g bismuth rotor lost about 0.3 g in anti-spin mode and gained 0.3 g (0.14%) in co-spin mode at MSFC on 7 Oct 2016, with the effect fading on repeat tests.
• For ordinary objects at realistic spin rates the predicted weight change is less than 1 part in 10^8, so only nuclear alignment could give a testable effect.
• The orbiting-gyroscope experiments gave no usable data because of bearing friction (NASA's own statement).
• The memorandum itself says that for a rotor the aligned fraction of nuclei is 'a very small fraction' even in strong fields at low temperature, and that the 0.14% result implies only 'a very small alignment fraction' (pp.30, 33); it gives no number for the alignment achieved.
• The authors argue the weight reversal was not a power-lead artifact because a three-phase motor reverses by phasing, not by reversing DC current, and that the magnets' external field was measured unchanged from test to test as the effect faded (p.33).

Relevance: Official NASA record of the father's late work on spin-coupled non-Newtonian force, the nearest published relative of the nuclear-spin experiment Amy planned (Alzofon); it also gives dates, equipment and the QM funding context. It is his paper, not hers. Table 1 reproduction: QE shows the table follows from eq. 28a with Appendix B's sign convention; the earlier 'not reproduced' remark is withdrawn.

Mainstream conflict: A spin-dependent modification of gravity or centripetal force contradicts the equivalence principle and Newtonian/relativistic mechanics, which are well tested; the kinetic-energy sign rule, the single-body 'natural orbit' and the extension to all central forces are postulates. The bismuth result is a 0.3 g shift on a single scale with acknowledged possible thermal and aerodynamic causes and no stated controls.

Independent test of Frederick Alzofon's 1981/1994 claim that pulsed dynamic nuclear polarization lowers a sample's weight. Alzofon (1994): 0.5 g aluminum powder with iron in plastic, about 0.33 T, 9.5 GHz pulses, a Mettler scale showed a maximum change of 1.1 mg (0.22%). The Dresden group used NMR pulses (30-300 MHz) in a 9 T cryostat at about 5 K, specimens (5 mm aluminum, brass, Al2O3, PTFE, YBCO) hung from an aluminum bending beam read by a laser interferometer. Low pulse counts gave no deflection down to about 0.38 microgram resolution (YBCO). High pulse counts gave deflections of about -0.1 to -0.25 micrometre (apparent -0.2 to -0.5 mg), similar to Alzofon's size, but also appeared with no specimen and tracked temperature; they attribute all of it to heat warming the helium and changing its refractive index (laser at 1.53 micrometre), not to gravity. They also note metals' skin depth (aluminum 9.2 micrometre) and YBCO's small penetration depth limited how much material was polarized (polarized mass of order micrograms), and that DNP polarizes at least ten times more nuclei than NMR, so Alzofon's own DNP setup was not exactly reproduced. Conclusion: the claimed effect is either unmeasurable by NMR, smaller than predicted, or non-existent. Amy Eskridge is not mentioned; her 2020 plan was to test the Alzofon experiment (the interviewer's plan, with her to travel).

Key claims

• Pulsed NMR on aluminum, brass, Al2O3, PTFE and YBCO at 5 K and 9 T produces no measurable weight change at about 0.4-9 microgram resolution at low pulse counts.
• The milligram-scale apparent weight changes at high pulse counts occur without any specimen and track temperature; they are explained by helium refractive-index change in the interferometer path.
• Alzofon's 1994 experiment reported a 1.1 mg (0.22%) weight change under pulsed DNP in about 0.33 T at 9.5 GHz.
• Because of skin depth and DNP/NMR differences, the Dresden test could not polarize enough nuclei in metals to rule out an effect at the claimed size.

Relevance: The only independent test in the folder of the Alzofon nuclear-spin weight-reduction claim that Amy and her interviewers wanted to replicate; shows what a controlled attempt found and what it could not exclude.

Mainstream conflict: Nuclear spin polarization changing weight would contradict the equivalence principle; the paper reports null results with a mundane explanation. The authors say their setup differs from Alzofon's (NMR not DNP; skin-depth limits).
