Title: Ever wonder how Saturn V "knew" exactly where it was pointing at launch?

Well, wonder no more!

The phrase "Guidance is internal" at T minus 15 seconds was one of the most important call-outs in the Saturn V countdown, and this fascinating short video with excellent graphics explains why.

Its the minute details like this that show just how complicated it is to send rockets to the moon.

Thanks, Smartcooky. I particularly enjoyed this little bit:
0:05:46  …it could align the gimbal to within one-thousandth of a degree.

I guess that's about near enough if I want to know in which way I'm pointing. :-)
