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 (or UAP) 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.
He claims to have viewed documents reporting that Benito Mussolini's government recovered a "non-human" spacecraft in 1933, which the Vatican and the Five Eyes assisted the U.S. in procuring in 1944 or 1945. Grusch claims second hand knowledge that American citizens have been harmed and killed as part of the government's efforts to cover up the information. In response to his June 2023 claims, the National Aeronautics and Space Administration (NASA) and the U.S. Department of Defense (DoD) issued statements reaffirming that no evidence of extraterrestrial life has been discovered and that there is no verifiable information about anyone possessing and reverse engineering any "extraterrestrial materials".
