Sirens are going off in the UK for the first time since 1996.
The UK has been hit by its first major air raid siren test since 1996, and it was all part of a nationwide trial to test the country’s air raid warning system. In a tweet, the National Police Chiefs’ Council said that sirens would be heard across London, Manchester, Cardiff and Glasgow on October 27th.
Air raid sirens were first introduced during World War II to warn people of impending attacks from enemy aircraft. They were used in Britain until 1996, when they were replaced by more high-tech methods such as text messages and automated phone calls. The decision to bring back the air raid sirens came after they were tested on April 27th this year, which led to a number of false alarms being reported across London.
What is an air raid warning?
An air raid warning is an alert that sounds when enemy aircraft are detected approaching or entering airspace above a particular area.
The term “air raid” refers to an attack by enemy aircraft and was used extensively during World War II.
While there are many different types of warning systems in place around the world today, including satellite detection systems and missile defence systems, many countries still use air raid warnings as part of their early warning system.
“Aircrews have always been fascinated with aircraft sirens – who can resist revving up a car engine at full throttle or standing outside an open window with your mouth wide open as you hear one pass?”
“During World War II there was a wide variety of siren types used by countries around the world.”
“The Germans used Lautsprecher (loudspeaker) systems while Italy employed loudspeakers mounted on trucks.”
“In Great Britain and Australia small versions were fitted onto cars while in America they were attached to ambulances.”
