The fact that they held a Congressional Hearing means it's something. Grusch's background is spotless, not your typical probed story. Not exactly the background and credentials of a crackpot.
Could be legit or could be a disinformation scheme to hide our own classified new tech flying capabilities.
Born in Pittsburgh, Pennsylvania,[2] Grusch was a decorated combat officer within the USAF during the War in Afghanistan and is a veteran of the National Geospatial-Intelligence Agency (NGA) and the National Reconnaissance Office (NRO).[3] From 2019 to 2021, he was the representative of the NRO to the Unidentified Aerial Phenomena Task Force.[4] From late 2021 to July 2022, he was the co-lead for UAP analysis at the NGA and its representative to the task force.[4] He assisted in drafting the National Defense Authorization Act of 2023,[5] which includes provisions for reporting of UFOs, including whistleblower protections and exemptions to non-disclosure orders and agreements.[6][7][8] Congressional interest in UFO sightings immediately prior to Grusch's public claims surrounded questions about the four objects that the Air Force shot down in February 2023.[9]
