Speaking of Murphy's Law, I read today that the cause of the parachute failure of the Genesis Probe reentry capsure is believed, at this stage, to be a gravity switch that was, well, installed backwards, resulting in catastropy. In short, a textbook case of Murphy's Law.
Ah, indeed, here's the article I read: http://www.sun-sentinel.com/news/local/florida/orl-asecmnasa15101504oct15,0,3696580.story?coll=sfla-news-florida
Also, "capsule" and "catastrophy." whoops.
