Hi,
I got interested in the use of computers (and hand calculations) in Apollo navigation. Is this detailed in a web book or press kit?
Thanks.

Try searching for "apollo guidance" at the NASA Technical Reports Server. But be prepared to spent the next week there... ntrs.nasa.gov/search.jsp

I thought that a resume could exist in a single document, but many thanks for this link!
I think I will!

One question about the LM lifting off. How did they time it? I know Houston did most of the math and relayed info to the astronauts, but did the LM AGC compute the time to lift off based on the CSM's orbit or was the time to lift off relayed to the LM? Found some cool info related to my own question here: history.nasa.gov/afj/loressay.htm

At five seconds before ignition, the Commander presses Abort Stage, which detonates explosive bolts holding the two stages together, and fires other charges to propel guillotines that sever wire bundles and plumbing that pass between the stages. I've heard that in the A/G recordings and I've always wondered if that button really did fire the bolt and cable cutters at that instant or if it simply enabled the computer to do so at the moment the ascent engine was started. I suppose that the ascent stage is well enough balanced on the descent stage that it wouldn't just slide or roll off the moment the Abort Stage button was pressed? Even at the most extreme landing angle?
