What are the big "remember-where-you-were-when-you-heard" events in your lifetime?

Some events have such a huge impact that we tend to remember where we were when we heard or witnessed them. Some of these for me were:
Obama wins election (2008)
September 11, 2001
The Colombine High School shootings
My mother’s passing
The first time I heard a speech by Bill Clinton
My father’s passing
John Lennon’s murder
Defeat of George McGovern by Richard Nixon
The Lunar Landing
The Kennedy Assassination
The first manned space flight
The launch of “Sputnik”
