Description
Please note: This is a companion version & not the original book. Sample Book Insights: #1 The truth about military intelligence work is that much of it is based on chance and tenacity. It is rarely glamorous. However, in terms of the effort involved, the flight of the Anson with the two-man crew was far removed from the abortive Elint collection mission off the coast of Great Britain almost a year earlier. #2 The Lorenz system was developed by the German company Lorenz to help aircraft find airfields in bad weather. It used two adjacent radio beams to mark a path extending up to thirty miles from the airfield. The signals interlocked, so that where the two beams overlapped, a listener heard a steady note. #3 The Luftwaffe had two blind-bombing systems, Knickebein and X-Gerät, that could be used by the entire bomber force. They were much simpler than the Lorenz system, and they used the same frequencies as the Lorenz airfield-approach receiver standard in all German twin-engined bombers. #4 The RAF had not considered it likely that German night bombing attacks would be a serious threat. In March 1940, a prisoner admitted under interrogation that Knickebein was something like the X-Gerät, about which he assumed his captors already knew.
