About this deal

stress: Description of force exerted on an object over a defined cross-sectional area. Stress = Force/Area It was ironic that, despite the Y-Device’s sophistication, this was the system Jones was most prepared for: it used the distance-measuring technique set out in the Oslo memo. pillaging vikings

It turned out their conclusion about code name Wotan was incorrect as it did not in fact imply a single beam. Jones 1978, p. 177 The idea of beam radio navigation was developed during the 1930s, initially as a blind landing aid. The basic concept is to produce two directional radio signals that are aimed slightly to the left and right of a runway's midline. Radio operators in the aircraft listen for these signals and determine which of the two beams they are flying in. This is normally accomplished by sending Morse code signals into the two beams, to identify right and left. Listening to BBC broadcasts (or any other banned broadcasts) in occupied countries was often punishable by death. In Poland it was illegal to even possess a radio. For these audiences the BBC broadcast a special news service in morse code, so that sympathisers could publish the reports in their illegal newspapers. p.m., after 90 minutes’ flying, they dropped their bombs on the city of Coventry and turned for home.

FIRST, THOUGH, the Vikings of KGr 100 would have their moment to shine. On the evening of November 14, its crews clambered into their Heinkels. The night was so clear that the observers could easily see the countryside below by the moonlight. Just after The Secret War was a six-part television series that was produced by the BBC in conjunction with the Imperial War Museum (IWM) that documented secret technical developments during the Second World War. [1] It first aired during 1977 and was presented by William Woollard, drawing on the first-hand recollections of participants from both sides. The principal interviewee was R. V. Jones, whose autobiography informed much of the research before its publication. [2] The opening music was an excerpt from Mussorgsky's Pictures at an Exhibition. The closing music was by the BBC Radiophonic Workshop.

It took Reginald Jones, Bernard Lovell, and other British radio scientists and engineers considerable effort and perseverance to turn the tide by developing a new radar technology and - eventually - win the 'radio war'.

The Luftwaffe, finally realising that the British had been deploying countermeasures from the very first day that the system was used operationally, completely lost faith in electronic navigation aids (as the British had predicted) and did not deploy any further system against Great Britain, [29] although by this time Hitler's attention was turning toward Eastern Europe.
