By all means order this original hardback rather than the far more expensive paperback reprint. R V Jones became famous when Churchill, in Volume III of his "Second World War", credited him with discovering the Luftwaffe's use of adapted Lorenz navigation beams to pinpoint night bombing targets in Britain. Jones explains this in depth, and includes his own version of his various meetings with Churchill. He goes on to discuss the discovery of German Freya and Wurzburg radar, culminating in the Bruneval Raid in 1942 in which Commandoes brought back German radar equipment from the French coast. He also mentions the dead-end of infra-red research, with which he had started his war. Here is a great expert at work, and in his own eloquent words. I have returned to this many times when I wanted to be crystal clear about the science, the sequence of events, and some of the key figures in wartime British radar intelligence. This is in no way a criticism because RVJ was describing his own war, not other people's, but a more rounded view of wartime radar can be found in the books by Watson-Watt (3 Steps To Victory), E G Bowen (Radar Days) and, for the very technical, Bragg "RDF 1". Obviously recommended.
