== Link: NASA DASHlink - Real System Failures The [[Observed Failures https://c3.nasa.gov/dashlink/static/media/other/ObservedFailures1.html]] slide deck from [[NASA DASHlink https://c3.nasa.gov/dashlink/resources/624/]] (via many places) is an interesting and even alarming collection of observed failures in hardware and software, mostly avionics related. I find it both entertaining and a useful reminder that all of this digital stuff is really analog underneath and that leads to [[interesting https://c3.nasa.gov/dashlink/static/media/other/ObservedFailures5.html]] [[failure https://c3.nasa.gov/dashlink/static/media/other/ObservedFailures24.html]] [[modes https://c3.nasa.gov/dashlink/static/media/other/ObservedFailures36.html]]. Lest you think that all of these were hardware faults and us software people can be smug, well, [[not https://c3.nasa.gov/dashlink/static/media/other/ObservedFailures40.html]] [[really https://c3.nasa.gov/dashlink/static/media/other/ObservedFailures41.html]]. There are more; read the whole thing, as they say.
