Recently while reading Yuval Noah Harari’s Sapiens I found an interesting excrept from it.
During World War Two, BBC News was broadcast to Nazi-occupied Europe. Each news programme opened with a live broadcast of The Big Ben tolling the hour — the magical sound of freedom.
The Genius German physicists found a way to determine the weather conditions in London based on tiny differences in the tone of the broadcast ding-dongs.

This information offered invaluable help to the Luftwaffe.
Luftwaffe is a generic German term for an air force. It was also the official name for the Nazi air force founded in 1935. Led by Hermann Goering, it became the largest and most powerful in Europe by the start of World War Two.

The Luftwaffe could now use the information of the weather in London to make valuable decisions in the war.
When the British Secret Service discovered this, they replaced the live broadcast with a set recording of the famous clock.
The World War 2 was not only fought physical grounds,but also on mental grounds too.
