Where the NIST report got it right.

This was a very interesting entry in 9-11B from Prof. Jones:

9/11 Soiree in LA with McKinney, Gage and Jones; plus some notes

"...I presented new SEM/EDS data on the red/gray chips -- and explained further research that is being planned and done to finish this up. (Hopefully the video will be available soon.) I also spoke about areas where I/we actually agree with NIST scientists and engineers, e.g.,

1. The "pancake theory of collapse" -- has been analyzed and dismissed by NIST in their reports. For example, in an FAQ released by NIST in Aug 2006, they write:

"NIST's findings do not support the "pancake theory" of collapse, which is premised on a progressive failure of the floor systems in the WTC towers."
wtc.nist.gov/pubs/factsheets/faqs_8_2006.htm

2. NIST rejected the false idea that the Towers were "hollow tubes" with the weight of the floors supported only by the perimeter columns. Quoting again from NIST:

NIST: "The core columns were designed to support approximately 50% of the gravity loads." [NIST, 2005] "The hat-truss tied the core to the perimeter walls of the towers, and thus allowed the building to withstand the effects of the aircraft impact and subsequent fires for a much longer time—enabling large numbers of building occupants to evacuate safely." [Sunder, 2006]
"The core of the building, which carried primarily gravity loads, was made up of a mixture of massive box columns made from three-story long plates, and heavy rolled wide-flange shapes." [JoM, 2007]

3. NIST also rejected the notion that the WTC fires melted structural steel:
"In no instance did NIST report that steel in the WTC towers melted due to the fires. The melting point of steel is about 1,500 degrees Celsius (2,800 degrees Fahrenheit). Normal building fires and hydrocarbon (e.g., jet fuel) fires generate temperatures up to about 1,100 degrees Celsius (2,000 degrees Fahrenheit). NIST reported maximum upper layer air temperatures of about 1,000 degrees Celsius (1,800 degrees Fahrenheit) in the WTC towers (for example, see NCSTAR 1, figure 6-36)." [NIST, 2006]
"The initial jet fuel fires themselves lasted at most a few minutes". [NIST, 2005; p. 179] "At any given location, the duration of [air, not steel] temperatures near 1,000 C was about 15 min to 20 min. The rest of the time, the calculated temperatures were near 500C or below." [NIST, 2005, p. 127]

4. NIST: "This letter is in response to your April 12, 2007 request for correction… we are unable to provide a full explanation of the total collapse." (Letter from NIST to us, pub'd in the Journal of 9/11 Studies.)
Shows remarkable and commendable candor!

I urged NIST to "open the door" and actually LOOK for residues of explosives/cutter charges (especially nano-thermite) -- as we have done.

I think there is an opportunity here -- Congress charged NIST to determine "why and how" the Towers AND WTC 7 collapsed. If NIST and Congress will just do their jobs -- and we stand ready to help! (See, e.g., Journalof911Studies.com .) At the same time, we're not holding our breaths -- our independent investigation of the causes of the WTC destructions is proceeding quite well (thank you!)..."
