This guy is just awesome in his understanding of stress, degins, and has a really good, data driven explanation for what happened. If only the government could function as good as he has. A convincing narrative, that also points out the biggest flaw in the whole event: Why didn't they close the road?

That is the first video, he then provides a super detailed, but clear, analysis of exactly what happened and why:

Very impressive job this guy does.
