and found "Operation LOOKING GLASS"
Looking Glass (or Operation Looking Glass) is the code name for an airborne command and control center operated by the United States. 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 name Looking Glass, which is another word 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.
The code name "Looking Glass" came from the aircraft's ability to "mirror" the command and control functions of the underground command post at Strategic Air Command headquarters.
On October 1, 1998 the U.S. Navy's fleet of E-6Bs replaced the EC-135C in performing the "Looking Glass" mission, previously carried out for 37 years by the U.S. Air Force. Unlike the original Looking Glass aircraft, the E-6Bs are modified Boeing 707 aircraft, not the military-only KC-135. The E-6B provides the National Command Authority with the same capability as the EC-135 fleet to control the nation's intercontinental ballistic missile (ICBM) force, nuclear-capable bombers and submarine-launched ballistic missiles (SLBM).
