Host Planet Earth by Colin Cooper and Anne Howell

Host Planet Earth is a BBC Light Program sci-fi serial in six parts originally broadcast between July and September 1967.

Produced by - Nesta Pain
Music by - Clive Webster, BBC Radiophonic Workshop

Set in England, the British space program is eager to compete and has gained an advantage with the invention of a propulsion system that enables exploration of distant regions of the universe within weeks instead of years.
The danger of invading – or invasive – alien species is only being realized very slowly, following some bizarre and seemingly unconnected events. Has that realization come too late?
