Horizon - man and science today.
Introduced by Christopher Chataway.

Rocketry, electronics, and nuclear bombs have radically changed the outward face of war. Robot missiles automatically seek and destroy their targets while 1,000 m.p.h. strike planes hedge-hop on radar guidance. But behind the battlefield is a huge sub-structure of research, where a computer can solve tactical problems in seconds, or a new weapon destroy military principles overnight.
How far are Britain's defence policies governed by the work of her secret army of scientists on the weapons and techniques of tomorrow?
