The ignorance! It reeks! The train was NOT "blown up with explosives" (one huge kaboom!). The vinyl chloride tanks were perforated with shaped charges so the contents would drain into a fire pit and combust. Combustion is not detonation. I worked in munitions and combustion, so I understand this. Or, the tanks would have exploded from overpressurization, launching a deadly chemical in all directions to considerable distances, where it would quickly evaporate and blanket the ground for the enjoyment of anyone breathing. Take your pick. I guess you would have done nothing...and enjoyed the pressure explosion. Then indeed, you "intelligent people" would have to "piece together the patterns and pieces."
