Other than 9-11 what event in history do you most remember?

SCPO David Lockwood Oh, another one for me was when Mt. Saint Helen's blew. I was 10 at the time, and we lived in Hillsboro, OR, roughly 90 miles away. Plenty close enough to see the mushroom cloud. Which, to my young mind that'd actually done duck-and-cover drills in 1st grade in preparation for a nuclear attack (like that'd do any good, right?), combined with the state of the cold war at the time...I immediately interpreted as a nuclear strike. I ran inside the house shouting to my mom that we'd just been nuked. She rolled her eyes, and turned on the tv where we learned the truth.

I could get into the 3 feet (literally) of ash that we got...but that's beyond the scope of your thread lol.

uss cole bombing

SCPO David Lockwood for me Challenger is number one. I had woken up really early in the morning to watch the launch with my dad. We were watching the launch, then we were not sure what we were watching, then it became clear watching a tragedy. I used to always get up with my dad and watch the launches. The Second is Columbia. I had just moved to Florida, my wife and our youngest daughter were listening to news coverage of the landing, and then they said it was gone. I remember telling my wife that they lost communication for a time during the re-entry. She said to me immediately that it was not that.

Pearl Harbor, 7DEC1941 and President Roosevelt announcing the attack on the radio.

Being a senior in high school and waiting for Shock and Awe to begin. Also a week or so later being the first one awake after a house party the night before and going upstairs and watching the invasion unfold on live TV.

I remember the first nights of Desert Storm like there were yesterday. I kept a log those two night, even though I was only 15 at the time.

The Berlin Wall coming down. My German-born mother cried all day, she was so happy.
The implications of that event were hard to grasp then, but it became clear in the ensuing months that the Iron Curtain was collapsing.

SCPO David Lockwood, as I’ve stated on another thread. I remember the “Iran Hostage Crisis” and the “Beirut Bombing” I also remember the “Challenger Explosion” and the “Oklahoma City Bombing” as well. I missed the "Moon Landing", I was just a thought then.

JFK’s Inaugural address, Jan. 20, 1961
And so, my fellow Americans, "Ask not what your country can do for you, Ask what you can do for your country."
Funny I was only 8 years old and still remember what JFK said, not everything else but just that. By the way, it was on a black and white TV, but now you can watch it on your cell, and still in black and white. Salute!

The Challenger, Chernobyl disaster, the Berlin Wall coming down, landing on the moon Cuban missile crisis, Watergate, 1st Gulf war and closer to home the 1st recorded F-5 tornado to hit in Minnesota. I know there are a lot more out there but these are the ones that popped into my head.
