Wasn't there a space mission that went up in a million-dollar explosion because someone typed a minus instead of a plus sign?
"A classic confusion between metric and imperial (English) measurement units has been reported as the probable cause of the loss of the $125M Mars Climate Orbiter." http://metrologyforum.tm.agilent.com/news19991020.shtml Lockheed Martin used imperial measurements, Jet Propulsion Labs used metric. Not quite a plus or minus sign, but also pretty close. And way more expensive.
There is a quote along the lines of 'Nothing can be made foolproof because fools are so ingenious' (possibly a Murphy's law derivative)
