I bet you were shown those 'Protect and Survive' brochures in class and probably also shown the dreaded PIFs of the time played from a VHS or Betamax tape through one of those big hulking TV sets wheeled into the classroom on a tall stand.
All rather quaint now, but my god, I do remember being shown some stuff, especially during PSE lessons that was rather shocking at times, including the ITV docudrama 'Starting Out' and certain episodes of BBC's 'Scene', etc (though that's for another thread to discuss more in-depth), but never 'P & S' nor anything else to do with the Cold War at the time.
