This documentary explores the extraordinary history of America’s airborne command posts—better known as “doomsday planes.” From the Cold War’s Operation Looking Glass EC-135s, which maintained an unbroken 24/7 airborne alert for three decades, to the E-4 Nightwatch 747s designed to safeguard presidential command, and the Navy’s E-6 Mercury fleet carrying out the critical TACAMO mission, these aircraft were built to ensure continuity of leadership and nuclear command in the event of catastrophe. Alongside them, the E-8 JSTARS provided unmatched battlefield surveillance and management. Together, these platforms reveal a hidden world of airborne strategy, technological innovation, and the immense responsibility carried by their crews—an often overlooked yet vital chapter in Cold War and modern defense history.
