In 2023, United States Air Force (USAF) officer and former intelligence official
David Grusch was interviewed by various media outlets and testified in a U.S. House of Representatives congressional hearing. Grusch claimed that he had conversations with unnamed officials that led him to believe that the U.S. federal government maintains a secretive UFO recovery program and is in possession of "non-human" spacecraft along with their "dead pilots". In 2022, Grusch filed a whistleblower complaint with the U.S. Office of the Intelligence Community Inspector General (ICIG) to support his plan to share classified information with the U.S. Senate Select Committee on Intelligence. He also filed a complaint alleging retaliation by his superiors over a similar complaint he made in 2021.
