He's a crank.

6.1 The Towers were built very strong in the 1960's
The above is a clear indication how the Towers were originally built by serious architects and engineers in the 1960's. Compressive static stresses in the columns were less than 1/3 of the yield stress of the steel before (obviously) ... and after serious damage (not so obvious but shown here)! The buckling stress of the column is virtually the same as the yield stress as the columns were arranged with spandrels. One reason why the static stresses were so low was that the designers had no access to computers to optimize (slender down) the construction. Manual calculations were done and to be on the safe side you added steel and built strong! And steel was quite cheap at that time. And US steel was good quality. The assumed yield stress 248 MPa was probably much higher in reality. NIST never checked the yield stress of the steel from the initiation zone in the rubble!
There was therefore plenty redundancy. A plane may crash into the bird cage and nothing happens. A big fire may break out and nothing happens. Why? Because the normal compressive stress in the supporting vertical structure is so low and if any column breaks or buckles, its load is transmitted to adjacent columns via the spandrels and the stress in adjacent columns increase a little. No global collapse is possible under any circumstances.

As you know by now I find it intriguing to speculate about how 9/11 was actually done and my present stand is CD - at WTC 1,2,7 and pentagon and no planes. Same at Shanksville but no CD ... and no plane, of course. Keep it simple.

From here.

It would appear that NIST, the US authority responsible for analyzing the collapse has abandoned the original suggestion of a rigid upper part free falling, impacting and causing a shock wave and instead suggests that 6-11 lower floors inside the upper part suddenly dropped down and overloaded the uppermost floor of the structure below. The above pictures evidently do not support such modified claim, where it is seen that the roof displaces 20-25 metres, while there is no visible effects at and below the initiation/impact zone at floor 94 (where the floors of the upper part are supposed to drop down). If only internal floors suddenly dropped down, evidently the roof would remain in position. It would appear that the core columns of the upper part above the initiation zone fail first, the upper part is compacted and the walls of the upper part telescopes into themselves. That the upper part does not remain intact should be obvious to anybody. However, a few days later an unknown professor announced exactly the opposite!
2.1 The false Theory and the misleading Assumptions
An American professor Z P Bazant published two days after the WTC destructions 911 a theory that was adopted by the authorities as true.

What I see is a fountain of debris and rubble thrown sideways in all directions - apparently caused by multiple controlled demolitions fired from top down and plenty of smoke, probably caused by the controlled demolition charges.s.
So, sorry! I cannot see anything that confirms your model and theory, Dr. G. But I wonder! Why do you invent such a stupid model and theory and publish it in the Journal of Engineering Mechanics? Are you working for the perpetrators of the controlled demolitions of WTC 1, 2, 7 or some agents of those? Do you think you can convince anyone with your unscientific nonsense? Why do you do it? Why not simply shut up like most other poor bastards and don't say anything. I don't expect you to be like me that can do real structural damage analysis and quickly see that WTC 1 destruction is not caused by crush down or PE>SE that NIST suggests.
Anyway - I have just updated http://heiwaco.tripod.com/nist7.htm . It seems NIST have destroyed all records how they analyzed and simulated the WTC 7 structural failures as presented in its November 20, 2008, report. There is no calculations, etc, of any kind left by NIST to support the WTC 7 final report! All destroyed ... if it ever existed. The NIST WTC7 report was laughable! A big section above floor 16 was dropping at free fall ... and deformed itself." (end of reply to G).
It is always nice with reader contacts! I will update this page when G clarifies his motives.

Or did someone try to discredit him as an anonymous imposter as has happened to other whistleblowers like Lisa Pease?
How to tell? Um, you could READ his own professional marine safety website-
