After reading the whole article, I’m satified that this was one of those “perfect storm” accidents where all the necessary elements came together to make it happen. Very few accidents have only a single cause.
If you conspiracy theorists have this much time on your hands, why don’t you go start the barbecue and see if you can melt steel with fire? As for me, I will spend my next few minutes praying for this family, what’s left of it.
