NASA TM-20205010911 "About the authors" (pp.37-38): Richard H. Eskridge "also researched the anomalous gravitational effects of electrically pulsed superconductors"; Michael P. Schoenfeld (at MSFC since 2005) worked on "anomalous gravitational effects of electrically pulsed superconductors" as well as POAMS; Michael A. Nelson, from 2011, worked on "Space Act Agreements to investigate breakthrough physics phenomena" with teams from "MIT; Italy; France; Los Angeles ... Huntsville" [read: TM pp.37-38].
This is a NASA-published statement that a pulsed-superconductor gravity investigation was done at MSFC by Eskridge and Schoenfeld, which matches Amy's account of the 2015 Poher-type test ("my dad did that") and Richard's 2019 website bio ("superconductor impulse gravity generators"). The "France" partner on an SAA is consistent with Poher (French) but the TM does not name him.
