There’s a whole community of people out there making mocked-up videos of Emergency Broadcast Tests, the system used to alert the populous to an imminent catastrophic event. Its curious how many people are attracted to imagining the end of the world (though I guess its been going on for millenia). If you’ve got the time, check out some of the related videos. This one has it all, with a plethora of sirens, scary lady robot voices, fat gothic typefaces and authentic 1980s ads.
