Two questions for you. Do you not see anything, anything at all, that looks questionable? Maybe not rising to a level of proof, but raising suspicions? Things that don't quite make sense? Things for which the official explanation seems even just a bit contrived? Nothing at all? I'm just wondering if in your pursuit of truth you've convinced yourself that there's no grey left.
Second question: if you're not a structural engineer, then when you see structural engineers writing in favor of one interpretation of events and other structural engineers writing to argue against that interpretation, what convinces you of one over the other?
