David Charles Grusch (born 1985) is a former U.S. Air Force officer and intelligence official who became the most prominent UAP-related whistleblower of the 2020s after publicly and then formally, under oath, alleging that the United States operates a decades-long secret program to retrieve and study non-human craft and biological material.[1]

Background

Grusch served in Afghanistan and later as a senior technical adviser to the National Geospatial-Intelligence Agency and the Pentagon’s UAP Task Force, giving him access to classified compartments relevant to his later claims.[2] He filed a formal whistleblower complaint with the intelligence community’s inspector general in 2022 and went public with his allegations in June 2023.

Congressional testimony

In July 2023, Grusch testified under oath before the House Oversight Committee that the U.S. government possesses “intact and partially intact” craft of non-human origin, and that he had been personally threatened in connection with his efforts to raise the issue through proper channels.[3] He did not present physical evidence at the hearing, saying it remained classified, and stated his testimony was based on interviews with others rather than direct personal observation of craft.

Official response and independent assessment

The Department of Defense has repeatedly and directly denied Grusch’s core claims. AARO’s 2024 Historical Record Report, a year-long review drawing on hundreds of interviews and extensive document review, found no verifiable evidence supporting the existence of a crash-retrieval or reverse-engineering program, past or present, and concluded that many such claims traced back to the same small set of unverified secondhand accounts.[4] Grusch and his supporters, including retired colonel Karl Nell, have maintained the AARO report itself is part of the same pattern of denial, while independent journalists have generally reported that Grusch’s specific claims remain uncorroborated by any produced physical evidence.[5] As of the most recent congressional hearings in 2025, Grusch’s central allegations remain unverified and disputed.
