Death of Antigravity Researcher Amy Eskridge Becomes 11th Case in Growing List of Scientists With U.S. Security Access Who Have Died or Vanished

The 2022 death of Amy Eskridge, a propulsion physicist who worked on advanced antigravity concepts, has been identified as the 11th case in a widening list of scientists and federally connected officials who have died or disappeared under unusual circumstances. The renewed scrutiny comes as researchers, family members, and open-source investigators compile patterns among deaths involving individuals with access to sensitive U.S. technical or defense information.

Eskridge, who held a background in physics and worked on unconventional propulsion research through her Tennessee-based company Innoventek, had attracted attention in niche aerospace circles for pursuing concepts related to electrogravitics — a controversial field exploring whether high-voltage systems can produce measurable reductions in gravitational effects. Although mainstream physics has generally treated such work with skepticism, portions of the research echo Cold War-era Pentagon and Air Force studies, some of which remained classified for decades. Eskridge’s sudden death, quietly reported in 2022, had largely escaped public notice until independent researchers began cataloging it alongside other cases involving scientists whose work intersected with national security or emerging technology sectors.

The list of 11 now includes biologists, aerospace engineers, federal contractors, and laboratory personnel whose deaths occurred between the early 2020s and the present. Some cases have been officially closed as suicides or accidents; others remain classified as undetermined. Analysts who have compiled the tally note that in several instances, the individuals involved had recently raised internal concerns, were preparing to testify, or held access to sensitive technical programs. Skeptics of the broader narrative caution that statistically, deaths among any large population of researchers — particularly those working in stressful fields — are not inherently anomalous, and that compiling disparate cases can create the appearance of a pattern where none exists.

What happens next will depend largely on whether any federal agency — the FBI, the Department of Defense Inspector General, or a congressional oversight committee — determines the pattern warrants formal review. At present, none of the listed deaths are being publicly investigated as connected. Family members of several of the scientists, including Eskridge’s, have called for greater transparency about the circumstances surrounding their loved ones’ deaths, while open-source investigators continue to add names and documentation to the running list. Observers will be watching to see whether lawmakers in either chamber request briefings or whether additional cases surface as awareness grows.
