This is not a talk about airplane crashes by Andromeda Yelton Are you: an embodied, thinking, feeling human who works together with other humans in a context of technical systems and wants that to go well? If so, let's talk about aviation: a field that's become exceptionally safe by obsessively investigating accidents and sharing lessons learned. In addition to being fascinating engineering detective stories, these retrospectives yield recommendations that are useful for anyone who said "yes" to the above questions. I'll tell you stories of key accidents in aviation history and what we can learn from them. (CW: injury, death.)
