On the brink of World War II, the huge Graf Zeppelin crossed the North Sea on a daring spy mission.  As the airship shadowed the eastern coastline all the way to Scotland, Fighter Command reeled in horror - the German spies were on the trail of Britain’s greatest secret. 

This documentary, released in 2010 for the 70th anniversary of the Battle of Britain, is a riveting story of the beginnings of radar in the UK with film footage from the time interspersed with expert analysis.

This series of documentaries was originally broadcast by the BBC at the beginning of 1977.  It is based on RV Jones's book 'Most Secret War' (see book list), which is an account of his part in British Scientific Intelligence between 1939 and 1949.  It was Jones' responsibility to anticipate German applications of science to warfare, so that their new weapons could be countered before they were used.
