I trust I'm the last nerd to see this, but it's still astounding -- eight minutes and 42 seconds of the July 16, 1969 launch of Apollo 11, as recorded at 500 frames per second. To save you from doing the math: that's the first 30 seconds of liftoff in real time. I would like to buy the guy who provides the commentary to this video a beer. He sounds awesome.
[Again, to save anyone the trouble of looking it up: Apollo 11 was the mission to the moon; "One small step for [a] man, one giant leap for mankind."]
