In December, the Defense Department declassified two videos documenting encounters between U.S. Navy F-18 fighters and unidentified aircraft. The first video captures multiple pilots observing and discussing a strange, hovering, egg-shaped craft, apparently one of a "fleet" of such objects, according to cockpit audio. The second shows a similar incident involving an F-18 attached to the USS Nimitz carrier battle group in 2004. The videos, along with observations by pilots and radar operators, appear to provide evidence of the existence of aircraft far superior to anything possessed by the United States or its allies. Defense Department officials who analyze the relevant intelligence confirm more than a dozen such incidents off the East Coast alone since 2015. Military departments and agencies treat such incidents as isolated events rather than as part of a pattern requiring serious attention and investigation. Reports from different services and agencies remain largely ignored and unevaluated inside their respective bureaucratic stovepipes. There is no Pentagon process for synthesizing all the observations the military is making. The current approach is equivalent to having the Army conduct a submarine search without the Navy. It is also reminiscent of the counterterrorism efforts of the CIA and the FBI before Sept. 11, 2001, when each had information on the hijackers that they kept to themselves. In this instance, the truth may ultimately prove benign, but why leave it to chance?
