When I was young I took a tour of an air traffic control center near New York. By the end I knew it was not for me. Everyone looked stressed. Things have gotten so much worse.

This guy was doing at least 3 people's jobs even before the first emergency occurred.

Then it was an inevitable cascade failure situation. It was never his fault.

Management failed here. If its stupid but it works, its not stupid, is the old saying, but the reality I've seen is its still stupid but you got lucky. -Maxim 43

The luck finally ran out.
