The talk focussed on failures I've encountered in multiple fields, and what I learned from reading from other people's failures, a common practise in aviation that has saved countless lives in not re-creating failures and accidents out of ignorance.
As they say in aviation "experience is a cruel teacher: she gives you the test first, and if you survive, then you get to learn the lesson".

After looking at examples of failures we experienced at Google, I give a fair amount of examples from aviation, from AF447, QF32, and the Boeing 737 Max disaster which is so many failures in so many ways that it takes a while to describe in details. My hope is that engineers in a similar situation where they know they are getting overruled, can use other escallation steps to avoid disaster for others.
