A tale of the supreme competence of Neil Armstrong
He overcame some computer problems as he landed the Lunar Module as well.  His experience, knowledge, and sheer courage were amazing.http://www.doneyles.com/LM/Tales.htmlABSTRACT: The Apollo 11 mission succeeded in landing on the moon despite two computer-related problems that affected the Lunar Module during the powered descent. An uncorrected problem in the rendezvous radar interface stole approximately 13% of the computer's duty cycle, resulting in five program alarms and software restarts. In a less well-known problem, caused by erroneous data, the thrust of the LM's descent engine fluctuated wildly because the throttle control algorithm was only marginally stable.
