Air Force Secretary Frank Kendall smiles after a test flight of the X-62A VISTA aircraft against a human-crewed F-16 aircraft in the skies above Edwards Air Force Base, Calif., on Thursday, May 2, 2024. The flight on the Artificial Intelligence-controlled VISTA is serving as a public statement of confidence in the future role of AI in air combat. The military is planning to use the technology to operate an unmanned fleet of 1,000 aircraft. (AP Photo/Damian Dovarganes)
