I know critical military and spaceflight hardware certainly is,
which is why I qualified my own statement with "public sector". :)
I would expect commercial flight hardware is probably similarly
robust, but I don't have any real knowledge of the stuff. The only
other public sector stuff I know of with this level of fault tolerance
is medical life support equipment.
Railroad signalling is a good possibility, I didn't think of that.
One might expect that to be highly fault tolerant. On the other hand,
from what I gather, it isn't. From what I can tell, they appear to
rely on the engineer to make intelligent decisions in the event of
signal failure.
