cvg2iln, What a strange snipe at an important book. The identification of individuals by RV Jones in his book is one of the aspects that make it so valuable. The book is a fairly deep record of some important work that UK scientific intelligence achieved in the period. It is not a chronology of British technical development, it is more of a record of scientific counter intelligence and concentrates upon; German Radar and navigation/targeting Beams, Rockets and V weapons, Night fighting equipment and techniques and, German progress towards Atomic weapons. The book describes how intelligence and scientific analysis was successfully used to develop effective countermeasures and tactics for most of the German technical advances. Some of the most enlightening information illustrates how internal British political and military lethargy sometimes caused avoidable Allied losses.
So, sorry cvg2iln, I don't agree with your generalised criticism.
