> Came down hot

Really that's all that needs to be said at the moment. They had way too much energy[1], which anyone with flight sim or RC experience will recognize as a routine mistake when hand-flying.

The question is why all (all!) the layers of checklists and warnings and process and ATC direction somehow failed in combination to prevent. Yeah, they should have aborted for sure, but they didn't, and we won't know why for a good while yet.

[1] Which can just as easily mean "too high" as "too fast", c.f. the sink rate warnings in the logs which would be consistent with trying to squeeze the airplane down onto the runway. But again we won't know without more data.
