I’d just like to point out that if you are in the computing industry long enough, you will get to see a few such incidents under different circumstances, not only in industries like aerospace. Mostly things like ECC save your a*, sometimes your software will be able to recognise a temporary spurious reading and disregard it because you had enough alternative checking logic, or in the case of realtime and safety critical maybe even your systems can take a vote between them. Got caught out by (cpu cache line) bit flips in the 90s, months of pain trying to track it down. Some of your will know :-)
