Initially they did not bleep people jumping out of the twin towers. I was in complete shock watching events transpire live on national news in my stateside barracks. Anyways as a genx'r earliest news reports I remember was princess Diana getting married in 81, on a more tragic and somber note I remember the 83 Beirut barracks bombing.. in regards to nuclear war "duck and cover" i guess it prevented observing firsthand a superheated fireball about to vaporize you.Reagan was sort of a lesser impact because it was reported that way. 9/11 was different because the whole world knew victims and watched the events play out on multiple computer screens across the country and world.
Networks may have bleeped it out but financial people saw the jumping and heard them hitting the awnings at street level. Interview conversations on the street often didn't even pause after an impact but the interview continued. People clung to the ledges with no hope of escape and everyone watched the desperation unfold. Rumors spread in seconds.
I'd say 9/11 and The Cuban Missile Crisis were equals because of the amount of unknowns. JFK was powerful because it was 100% unexpected and he was so well liked. If you were a kid, you'll never forget Nov 22. I note there was no notice of the event on the news this past year. I guess it's history now.
The nukes from Cuba were supposed to be launched the next AM and I recall it reported and talked about that way. Adult men that had fought with fixed bayonets in the sands of Europe were afraid and said so.
