Ever wondered what really controlled the last minutes before a Saturn V liftoff?
In this video, we go inside the Terminal Countdown Sequencer — the relay-based machine that issued commands, demanded confirmations, and decided whether the launch could proceed or be cut off. From tank pressurization to guidance release and engine ignition, this is the system that turned the final seconds into proof.
▶️ Watch now and experience the engineering that made Saturn V possible.
