While that is true for some general aspects, digital computers were used to make more precise computations or when there was simply no other way.

Oh, and the scientists and mathematicians used slide rules.

I was always a little bit in love with Jim Lovell. He has a brief appearance in the Star Trek Enterprise intro.  :-*

I thought Apollo 13 was a great movie and highlighted Lovell's incredible career and accomplishments.  The Right Stuff was also a great movie and I have HBOs miniseries From the Earth to the Moon on DVD. All good stuff.

Thanks. Very cool. Mostly over my head, but very cool.

Little Joe:
United Launch Alliance will be launching a Delta IV heavy tonight.  I'll probably be asleep, but if I happen to be taking one of my nocturnal walks, I might check it out.  It launches just a bit south of here.
