The United States and Soviet Union are in a Cold War and have fought a proxy war in Korea. The Soviet Union is expanding Communism behind its closed borders and is competing with the United States in the Nuclear, weapons, and space races. The United States needs to know what the Soviet Union is up to behind the Iron Curtain, but to do so requires a revolutionary surveillance plane capable of overflying the Soviet Union undetected and high enough to escape the missiles of its Cold War enemy. When the US Air Force refuses to develop such a plane, the US president goes to the Central Intelligence Agency who undertakes the development of the U-2 plane. The CIA needs a remote location to secretly develop the U-2 and to train its pilots. The agency selects a remote site in Nevada along the nation’s western line of defense established in World War II. The secret location becomes known as Area 51.
