Man's magnificent achievement: two astronauts, Neil Armstrong and Edwin "Buzz" Aldrin, land and step foot on Earth's moon. (Command module pilot Michael Collins stayed in moon orbit.)
I remember the night very well. My family was living in then West Germany and we watched the Apollo 11 coverage on German television. The audio of Armstrong stating "the Eagle has landed" was all we had to hear to know that history had been made.
That was a special time.
