Any others? :Anniversary or no anniversary, launch Discovery only when Crippen :is absolutely sure that there is nothing wrong and the Challenger :tragedy should not as far as it is humanly possible be repeated. If :there were no human lives at stake, go ahead and launch it but since :it is a manned mission all precautions have to be taken. I disagree, strongly. There should have been an investigation of the Challenger disaster, and when they found that the O rings failed below a certain temperature, they should have continued launching >above that temperature<, while working on a better engineering solution. There are many, many qualified scientists and pilots willing to risk their lives in spaceflight. The engineering effort necessary to move from a 95% safety record to a 99.9% safety record has stunted the US space program, focussed its energy in introverted paranoia instead of a healthy adult acceptance of risk, and mave have given the Soviets an unbeatable lead in space travel. To me, the latter also implies the potential for Soviet domination of the entire Earth. Michael Sloan MacLeod (amdahl!drivax!macleod)
