The section on the "NASA Mars Lander" warrants an extra paragraph:

The Mars Polar Lander smashed into Mars, due to a premature shutdown of descent engines when software incorrectly interpreted a spurious sensor signal as meaning it had touched down. In addition, the Mars Climate Orbiter had a navigation flaw due to mix-up of English and metric units, more a pure play on human error and process bugs than real software bug. It is assumed to have broken up in the Martian atmosphere.

The USS Vincennes is erroneously referred to as the "US Vicennes."

Thanks to Chuck Howell for the feedback.
