The hidden record is extensive and cross-corroborated. David Grusch, a former National Reconnaissance Office and UAP Task Force officer, provided sworn congressional testimony in July 2023 stating the U.S. government has retrieved 'non-human intelligence' craft and biological remains — a claim he made under penalty of perjury. This corroborates earlier testimony from Bob Lazar, who in 1989 described reverse-engineering extraterrestrial craft at a classified facility designated S-4, adjacent to Area 51, and identified element 115 (moscovium, later confirmed on the periodic table in 2003) as the propulsion medium. William Tompkins, a former Douglas Aircraft Company technical illustrator with a Navy Intelligence background, documented in 'Selected by Extraterrestrials' (2015) that Navy spies embedded with Nazi Germany returned with intelligence suggesting the Germans were receiving ET assistance — and that the U.S. subsequently ran parallel programs. Dr. Steven Greer's Disclosure Project (2001) assembled over 400 military, intelligence, and government witnesses on record, including Brigadier General Stephen Lovekin and FAA Division Chief John Callahan, who described active coverup protocols. Hal Puthoff of SRI International, who ran the classified Stargate remote viewing program, has since publicly stated that retrieved materials with anomalous isotopic ratios have been held in private aerospace contractor custody — a claim corroborated by Lue Elizondo, former director of the Pentagon's AATIP program. Richard Dolan's forensic analysis in 'UFOs and the National Security State' catalogues thousands of declassified documents establishing a continuous, deliberate suppression architecture dating to 1947.
