In a 10,000 page report NIST make no effort to quantify the RATE of rotation of the upper block of either tower. In fact NIST lose interest in the collapse about 2 milliseconds after collapse initiation. The rotation of the upper section of the towers, especially WTC 2, was SUBSTANTIAL and crucial to the collapse mechanism. NIST describe it differently in two different sections of the report. NIST's scientists, (god bless them), should do a better job of proof reading their reports and learn some trigonometry while they are at it! If I had just paid $20 million for the NIST report, I'd be asking for a refund!
So you can call it "nit-picking" .... I call it "doing a full and complete collapse analysis"
As for the absence of peer reviewed papers contradicting NIST and Bazant - try reading Cherepanov's paper in I. J. Fracture 141, 287, (2006).
And as for X-ray analysis of materials, I did it for a living for 15 years. Peak heights for adjacent elements in an x-ray spectrum are a pretty good approximation because the x-ray absorption effects are about the same. Oh. and by the way, if chlorine was coming from the water it should be in every concrete spectrum. It isn't! Besides, chloride ion is a no-no in concrete and is generally kept as low as possible
As for a new collapse theory: I have some ideas but, based on the reaction of most JREFers to most of my points, I sense the NISTIANS (who appear to dominate this site) are not ready to look "outside the box", especially when its quite apparent they think they already know all the answers. This approach to 9/11 "research" is based more on CONVICTION rather than CURIOSITY.
I worked many years with nuclear engineers who behaved the same way. When we found a problem with a reactor, the engineers were more concerned about making up a plausible STORY to tell the Nuclear Regulators than getting to the truth. Looks like the engineers at NIST have the same mind-set.
