As somebody who grew up during the Cold War, seeing those red lights flash still sends shivers down my spine. I lived yards away from UKWMO / ROC Group Control No.1.
🇬🇧, 😬 - how realistic that small/miniature replica 3D printed “British” air-raid/civil-defence siren sounded to its full-sized vintage/war-relic equivalent, the uniqueness of the siren being the duel-tone pneumatic/air-chopping type? I like to think that, like the French ~ if the UK had kept its siren network after the Cold War, it would be more effective “alarm” system than the government emergency message now mass-sent to our smartphones - with those you can choose to “ignore” them, but with a siren sounding the “alert” outside, you are certainly not going to ignore it 😨 and unlock phone, turn on the telly/radio to hear the warning and take the appropriate action
