Cold War bunker found in Brooklyn Bridge

"NEW YORK (CNN) -- New York workers have discovered a trove of Cold War-era supplies within the masonry of the Brooklyn Bridge, a cache meant to aid in survival efforts in the event of nuclear attack...
Some containers were marked with two dates notorious in the annals of the Cold War: 1957, when the Soviet Union launched the first satellite into space, and 1962, the year of the Cuban missile crisis when the two superpowers may have come closest to war."

"Sarlin said one of the containers was marked, 'To be opened after attack by the enemy.'"
