Before an air raid began two warnings were sounded - amber (yellow), then red alert. When it was safe to leave air raid shelters and walk about an 'all clear' signal was sounded.
They were alerted by the sound of the sirens, which are used nowadays as signals to tell factory-workers that their shift is finished.
Even if this didn't work, they had developed a radar system that was installed along the coast of England. This consisted of towers that transmitted radar signals that could detect German bombers while they were still over France.
----------------------------------------------------------------
The population was warned of air raids by the sounding of a loud air raid siren to warn of the start of a raid and again at the end of the raid to indicate that all was no clear.
As soon as approaching enemy aircraft were detected by radar, air raid sirens were activated to warn people to take shelter. Some people had their own purpose built shelters at home and there were public shelters for people who were - for example - out shopping at the time. Factories and businesses usually had their own shelters for the use of staff. When the raid was over, the sirens sounded again (with a different tone) to signal 'all clear'
Sirens were sounded with different signals - one for alert, another for all clear.
People knew because their was a siren to alert them.
There was an air raid siren that went off when planes with weapons from an enemy country were spotted.
They were warned by the sounding of an "Air Raid Siren" after the raid was over the siren would sound again to give the "all clear".
Air raid sirens were sounded to warn people to take shelter. The siren was sounded again once the air raid was over and they could emerge from the shelters.
People felt often terrified and scared in the blitz because they didn't know what was going to happen. They feltscaredterrifiedanxiousworried
I have actually spoken to a mayan. 2012 will not be the end of the world first off. He said in 2012 there will be a change, but it will not be the end of the world. We do not exactly know what is going to happen on 2012. some people say world is going to end but some say it is not going to happen. The truth is if its really going to happen, before that particular incident happens several disastrous would take place. Hence if we are patient we would come to know the truth.
Sirens that could be heard through the city would go off to let people know that they should seek shelter.
no one knows. but i think that how people say the world will end, people getting smashed, drowned, blown up, etc. will not happen. i don't know why God would "torture" us in that way. i just believe that when it happens, it will happen quick and simple.
the problem is that the world is going to end and this is not the answer i think it isn't because i just don't know but the world isn't going to end so don't take this for real because it isn't going to happen
You don't that's the whole point of raids your not meant to know.
A plane would be spotted on-radar or it would be sighted, in both cases the air raid siren goes off.
no you don't know what's going to happen in your future Helen Milner.
They react scared because they don't know when it's going to happen.
when you know something is going to happen it is called a prediction. hope this helps ...x when you know something is going to happen it is called a prediction. hope this helps ...x
People usally ask the question they already know the answer to when they do not want to believe in the truth, when they are in shock of what is going to happen.
It's not really going to happen. It was for amusement only & people should know better.

to me i think we observe them to know which is going to happen or to notice when an eclipse is going to happen
