For me, one of the key quotations and take-aways is this:<p>> <i>In almost all software-related aerospace accidents, it turns out that the software is behaving as designed, but the designed behaviour was not safe from a system viewpoint.</i><p>There is more that is of value. For people - like me - who have designed safety-critical systems, and for people who want to do stuff that potentially has deeper consequences when it goes wrong, this is an interesting article.<p>But it's not a tutorial. You need to study it to find the lessons, you need to read with attention and extract the value. As with learning to program, learning to dance, learning math, learning to juggle, <i>it's not a spectator sport.</i><p>If you want to get into anything that has a safety aspect, this article isn't a bad place to start.
