Through the story of a German night fighter captured in Suffolk, Michael Portillo remembers the crucial electronic war waged between the Axis and the Allies.

In July 1944 the crew of a Junkers JU88 night fighter, lost and without fuel, emergency landed their plane on an RAF airfield in Suffolk. This gift from the skies provided British Air Intelligence with the latest German radar secrets. Throughout the war a technological see-saw had been underway with each side trying to gain the the advantage in radar detection and evasion equipment. The radar technology in this particular night fighter explained why large numbers of British bombers were being shot down from the rear and the RAF aircraft were quickly modified as a result.

Alongside distinguished historians and veterans of RAF Bomber Command, Michael pieces together the story of that fateful night. He also explores how it illuminates the vital - yet lesser known - battle front of electronic warfare
