Close Encounters of the Fifth Kind

The Center for the Study of Extra-Terrestrial Intelligence defines a “Close Encounter of The Fifth Kind” as direct human contact and communication with extraterrestrial life. But is this a classification that will only be useful in the distant future, or have such encounters already taken place… and within the highest levels of the U.S. government?
