One of the biggest mistakes is to assume that systems are only
safety-critical if they physically control the hardware that is capable of
doing the damage.
I came across a stylesheet recently with a bug: it was designed to display
out-of-range data in red, and this wasn't happening, because the code was
doing a string comparison rather than a numeric comparison. I can think of
many scenarios where this could have fatal consequences: admittedly they all
have a human in the loop, but that's not guaranteed to prevent the disaster
happening.
