I'm really at a loss of words. There is only one lesson from this incident: nobody is supposed to touch a 500M piece of equipment after 12 hours of work. Period. The author is not getting it, and nobody in the comments. The world is run by idiots and it shows.

It seems like there was a lot of pressure to meet the deadline and everybody overworked in this environment. A perfect example of normalization of deviance. It's a shame that there still exists many workplaces like that. It's our duty to be aware of what's happening around us and tell the guy - Hey, what the fuck are you doing here? Get home, that's no critical emergency.
