"By
April 1967, Looking Glass crews possessed the capability to launch
selected Minuteman ICBMs via an airborne launch control system (ALCS).
A SAC general officer, with special training in emergency war order
(EWO) implementation and in nuclear command and control procedures, was
in command of each Looking Glass aircraft. This “airborne emergency
actions officer” (AEAO), had authority to act for and on behalf of the
commander in chief, SAC, in any confirmed wartime emergency. Indeed,
should the president and the NCA become incapacitated, the AEOA could
act for them."
