One of my hobbies is shooting fire effects at big music festivals. We're shooting huge flames in front of 10s of thousands of people. I think that is pretty safety-critical. We have a very rigid communication protocol that I designed based on my experience as a pilot and all the time I've spent flying with my father, who is a very experienced pilot. The communication protocol and operational checklists are there specifically to catch human errors. For instance: "snoop" (which is a sort of soapy water used for checking gas lines for leaks) every gas line any time it is changed. Snooping something, finding a leak, and then either reseating the gas fitting or shutting off its supply is the system working properly. You could absolutely write an article that said "multiple gas leaks found on fire effects system", omitting the part where they were immediately found and fixed as part of the operation of the system. I also wrote the ignition and control systems for a fire effect that we use, which has fail-safes built into every stage of its operation. That doesn't mean that failure modes don't ever occur (for instance: dead battery on the controller, out of range events, etc), it means that I designed around them so that they occur safely. So I'm sorry that you wouldn't hire me for safety-critical systems. I'm curious what safety critical system you design or manage, because the idea that you either don't think errors will ever occur, or don't know what they are and how to design around them, is perplexing.
