Thanks for the ping.
I wonder if the accident may be due to a situation where the people were overworked and understaffed -- those are conditions conducive to terrible industrial accidents.
Would love to know the details of why the LEOs have declared it a crime scene.
Evidentally, we won't have a clue what transpired until they can search through ALL the wreckage. Also, I wonder if part of the problem in identifying casualties and/or missing is that there were lots of contractors and sub-contractors and sub-subcontractors at work on the new plant.
