This is a percentage of fatal accidents, which on the whole are very statistically unlikely (they account for less than 1% of all accidents). Just because someone didn&#x27;t die doesn&#x27;t mean an accident was inconsequential.<p>In other words, if I told you 1&#x2F;3 of fatal airline crashes were caused by drunken pilots but half of all airline crashes were caused by fatigued pilots, which would you try to fix first?
