The comments on the WSJ piece are particularly interesting to me as representative of how people tend to mentally approach stuff like this or choose to mentally stonewall it.
It is a tough puzzle and pretty hard to know for sure of the validity of the various pieces of official information. There is next to nothing to go on, unlike say a 9/11 where you can take occam's razor and peel it down to the properties of structural steel and physics, which are quite constant.
