hope no one minds me dragging this to the top again, i was going to make a post about air raid sirens but thought id do a search first.
i remember when i was a kid, about 8 years old, you could see the old sirens perched atop poles around the town i live in. there are none around anymore.
during the mid to late 80s for some reason the sirens went off when they shouldnt have when i was at school one day. the teachers went into a complete panic and made us hide under our desks. cannot for the life of me find anything on google about it but i know its been discussed on the boards of friends reunited for that school.
my mum was brought up in tooting and remembers hearing the wail of the siren that was situated at tooting bec asylum signalling an escapee, as did my ex's mum who lived in coulsdon and often used to hear the wail coming from cane hill.
