Declassified U.S. government documents confirm that UFOs have repeatedly visited nuclear weapons sites—laboratories, plutonium production plants, bomb test ranges, missile warhead storage depots, ICBM launch silos—as early as December 1948.

Furthermore, KGB and Ministry of Defense documents released or leaked following the collapse of the U.S.S.R. verify that the Soviets also experienced such incursions at their nuclear facilities during the Cold War era.

In short, someone or something operating highly superior aerial craft has been monitoring and sometimes disrupting the functionality of American and Russian nuclear weapons for decades.
