One of them then said that there was to have been a similar raid on Wolverhampton under the code-name “Einheitspreis”. Felkin explained that “Einheitspreis” meant “unit price”, as at Woolworth’s where most things cost sixpence, and this was an obvious link between the code-word and the target town. p.m., after 90 minutes’ flying, they dropped their bombs on the city of Coventry and turned for home.

In fact the Government had recognised this long before hostilities broke out. Throughout the 1930s, as the Nazi threat was looming over Europe, then Director-General John Reith was in secret discussion with the Cabinet over broadcasting arrangements in the event of war. It was agreed that the BBC should seek to report events truthfully and accurately, but not in such detail as to endanger the civilian population or jeopardise operations. A few months earlier, the British had captured a largely intact German Heinkel He 111 bomber. Jones pulled out the report on it and looked at the list of radio equipment found onboard. It included a blind-landing receiver—designed to guide pilots to the runway in darkness or bad weather. During testing, beam deflection (vertical distance moved) shall not exceed one-quarter inch. If a beam deforms this much without breaking, it is considered failed. 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 British sceptics started regarding the system as proof that the German pilots were not as good as their own, who they believed could do without such systems. The Butt Report proved this to be wrong; aerial reconnaissance returned photographs of the RAF bombing raids, showing that they were rarely, if ever, anywhere near their targets.

First published in 1927, it is the story of a talented yet over-ambitious Russian engineer, who wants to control the world with the help of a powerful laser-like beam he has developed which is capable of destroying everything in its path. Pacy, superbly plotted and unputdownable, it was one of the best sci-fi thrillers ever to come out of Russia.

That is changing, albeit slowly. Ukrainian officials hope to phase out the Chinese DJI consumer drones that are ubiquitous on both sides of the front line in favour of more professional platforms. “One of the takeaways from Ukraine is that having any unencrypted radio link is no longer a choice,” says Mr Withington. “If you’re NATO, you need to encrypt everything.” Even then, M-code would offer only “marginal” benefit, cautions Mr Goward, because the technology is now nearly two decades old and GPS signals are inherently weak.

They also believe that the Germans, without the same naval tradition, will never be able to find targets at night. They are, again, wrong. In 1939 the Germans don't just have radar to spot planes entering their airspace, they have radio beams to guide their own planes into enemy airspace. KGr 100 targeted British factories at night. It was safe work: the squadron dropped 156 tons of bombs that August, and just two members of the unit were injured. Only one plane reported damage from enemy fire. When evaluating solutions it is important to take into account a range of constraints including cost, safety, reliability and aesthetics and to consider social, cultural and environmental impacts.

However, shortly afterwards he had an enthusiastic telephone call from Squadron Leader Felkin, who said that a conversation between two German prisoners had been overheard. They said that the raid on Coventry had been very successful and so had the raid on Birmingham. The German military partnered up with the Lorenz company to develop a blind approach system in 1930. The system used a simple dash and dot system like Morse code. As the British slowly gained the upper hand in the Battle of the Beams, they started considering what the next German system would entail. Since Germany's current approaches had been rendered useless, an entirely new system would have to be developed. RAF Bomber Command continued to insist that navigational aids were unnecessary. That complacency was shaken in mid-1941 when a study found that of British bombers claiming to have reached their target, only a third had dropped bombs within five miles of it. By the following year, the RAF, partly inspired by the Germans, had adopted radio navigation and pathfinders to locate its targets.
