My favorite part of Apollo 13 is when the Mission Control guys bust out their sliderules, pencils, and paper to confirm a calculation. I don't know if they even still teach how to use a sliderule any longer. People forget what was common practice before easy access to computers, and it make me sad. Vixen is advancing a version claiming our lack of 21st century computing technology is proof the lunar landings were not possible. It's the same thing as claiming the Egyptians couldn't have built the pyramids because they lacked heavy euipment.
That;s why I don't mind posting in this thread. People need to be reminded how smart people once conducted affairs with hopes these practices aren't lost to time.
