Wallace and Gromit's World of Invention Episode 5 - Better Safe Than Sorry Episode Title:Better Safe Than Sorry.Episode Description:Wallace and Gromit have always taken their safety into their own hands, and in this episode of the science series they consider other inventors with the same philosophy. They tell the tale of 1940s Hollywood starlet Hedy Lamarr, who had a side-line in inventing, and who devised a radio-controlled 'secret-communication' system for steering torpedoes to help allied forces in the war. They also look at the most futuristic surveillance drones and the history of spy technology. Gromit really goes through the wars in this episode (he keeps suffering from accidents instigated by Wallace throughout apart from curiosity corner).
