Mindblowing. Took a walk. All I can say is that if business continues "as usual" and the economy and public services continue largely unaffected then either there were local copies of critical documents, or you can fire a lot of those workers; either one of those ways the "stress test" was a success.
The fire started on 26th September and news about it reached HN only now. I think this is telling how disruptive for South Korea daily life this accident really was.
Yeah you can do the same with your car too - just gradually remove parts and see what's really necessary. Seatbelts, horn, rear doors? Gone. Think of the efficiency!
Long term damage, and risk are two things that don't show up with a test like this. Also, often why things go forward is just momentum, built from the past.
