As I am a direct descendent of Sir Christopher Wren and have many ancestors from London who were members of various Livery companies. I have decided to create this article about Radar which invention helped us British win the second world war.
In 1934 a large-scale Air Defence exercise was held to test the defences of Great Britain and mock raids were carried out on London. Even though the routes and targets were known in advance, well over half the bombers reached their targets without opposition. Prime Minister Baldwin’s statement “The bomber will always get through” seemed true.
To give time for their guns to engage enemy aircraft as they came over, the Army was experimenting with the sound detection of aircraft by using massive concrete acoustic mirrors with microphones at their focal points.
