The Pentagon's fourth batch of declassified UFO files makes one thing undeniable: unidentified craft have been breaching America's most sensitive nuclear sites for decades. A silent, diamond-shaped object hovered over the Pantex nuclear weapons plant in 2015 with no visible propulsion, and military aviators have tracked objects moving at speeds and with flight characteristics that defy explanation. This level of transparency — 40 files spanning agencies from the CIA to the Energy Department — is exactly what the public deserves.
