The United States Air Force begins Operation Looking Glass, and over the next 30 years, a "Doomsday Plane" is always in the air, with the capability of taking direct control of the United States' bombers and missiles in the event of the destruction of the SAC's command post.

The United States Air Force (USAF) is the air service branch of the United States Department of Defense. It is one of the six United States Armed Forces and one of the eight uniformed services of the United States. Tracing its origins to 1 August 1907, as a part of the United States Army Signal Corps, the USAF was established by transfer of personnel from the Army Air Forces with the enactment of the National Security Act of 1947. It is the second youngest branch of the United States Armed Forces and the fourth in order of precedence. The United States Air Force articulates its core missions as air supremacy, global integrated intelligence, surveillance and reconnaissance, rapid global mobility, global strike, and command and control.

Looking Glass is the historic code name for an airborne command and control center operated by the United States. In more recent years it has been more officially referred to as the ABNCP. It provides command and control of U.S. nuclear forces in the event that ground-based command centers have been destroyed or otherwise rendered inoperable. In such an event, the general officer aboard the Looking Glass serves as the Airborne Emergency Action Officer (AEAO) and by law assumes the authority of the National Command Authority and could command execution of nuclear attacks. The AEAO is supported by a battle staff of approximately 20 people, with another dozen responsible for the operation of the aircraft systems. The name Looking Glass, which is another name for a mirror, was chosen for the Airborne Command Post because the mission operates in parallel with the underground command post at Offutt Air Force Base.

Strategic Air Command (SAC) was a United States Department of Defense Specified Command and a United States Air Force (USAF) Major Command (MAJCOM) responsible for command and control of the strategic bomber and intercontinental ballistic missile components of the United States military's strategic nuclear forces from 1946 to 1992, active for most of the Cold War. SAC was also responsible for strategic reconnaissance aircraft; airborne command posts; and most of the USAF's aerial refueling aircraft.
