We all know where we were when 9/11 happened, and probably Challenger... maybe even Columbia. Same with Waco, and at least for those of us anywhere near Philly, The Move. Many here are old enough to remember the assassinations of Kennedy and MLK Jr.
My earliest memory of a major news event was the death of Elvis in 1977, mostly because that breaking news interrupted whatever cartoon I was watching, and I remember my mother (prime age to be an Elvis fan) shushing me to hear the news on the TV.
I guess I should remember the John Lennon assassination, but since my parents were too old to be into the Beatles, that one didn't even get honorable mention in our house. The Ronald Reagan assassination attempt was much bigger news, at least in our house.
What's the earliest major news event you remember experiencing, live? Anyone here old enough to remember FDR dying in office? Harding? VE or VJ day?
