Today is the 30th 40th* anniversary of the most expensive flubbed line in history. "One small step for A man, one giant leap for mankind."
This is one of the three "where were you when..." moments in my memory (moon landing, Challenger explosion, 9/11). Actually, I have a fourth of equal power for me, but it does not seem to be on very many other people's lists. That was the moment in 1989 I turned on the TV and saw people climbing on and partying around the Berlin wall. I don't know if there was simply not any warning for this moment, or if I was in some kind of new job lala land and missed the lead up, but it was a real wtf moment for me, a total surprise.
* This is the second time I have done this in a week, dropping a decade in the math. I think it is some subconcious process fighting aging.
