BATTLE OF THE BEAMS (PB)

World War II. The British believe that they alone have a war-winning weapon: radar. They are wrong. They believe that their unique maritime history means their pilots have no need of navigational aids and that the Germans, without the same naval tradition, will never be able to find targets at night. Again, they are wrong. The Germans have developed radio beams to guide their own planes into enemy airspace. Luckily, one young engineer is able to convince Churchill, and a room full of sceptics, just how much danger they’re in.
