Any news on NIST WTC7 data?

Does anyone know what the situation is regarding the NIST WTC7 simulation data?

There were two terabytes mentioned back in February 2009 by AE911...were these files obtained and uploaded to

It seems NIST also recently released 8,910 files to Ronald Brookman of Cryptome, I wonder if he will make these available? They withheld 3,370 files for reasons of 'public safety', including the 'connection models' and all 'results files'.

EDIT: The data which accompanied the letter above is available:

I can't find a reference to either data set on this site about the simulation, though there are links to two (unreadable?) LS-DYNA files found on a NIST ftp site (under 'World Trade Center 7 Computer Simulations')

I think this is going before

I think this is going before federal judges. I feel we may hear something in April or shortly thereafter unless the process gets prolonged.


NIST gave the same excuse they gave to Mr. Brookman, specifically that:

These records are currently exempt from disclosure under section (b)(3) of the FOIA, 5 U.S.C
§ 552 (b)(3). Exemption (b)(3) permits an agency to withhold records in an agency's possession
which are records that are "specifically exempted from disclosure by statute (other than 5 U.S.C
552(b)), provided that such statute (A) requires that the matters be withheld from the public in
such a manner as to leave no discretion on the issue, or (B) establishes particular criteria for
withholding or refers to particular types of matters to be withheld."

The statute underlying the (b)(3) exemption in this case is the National Construction Safety
Team (NCST) Act, 15 U.S.C. § 7301 et seq. Section 12 of the NCST Act (15 U.S.C. § 7311)
provides that it applies to the activities of NIST in response to the attacks of September 11, 2001.
Section 7(d) of the NCST Act (15 U.S.C. § 7306(d)), exempts from disclosure, information
received by NIST in the course of the investigations regarding building failures if the Director
finds that the disclosure of the information might jeopardize public safety. On July 9, 2009, the
Director of NIST determined that release of the withheld information might jeopardize public
safety. Therefore. these records are being withheld.

I am working on getting the data NIST sent Mr. Brookman, and will put a link here as soon as it's available.
EDIT: (the link is now posted above)

"Our study has identified thermal expansion as a new phenomenon that can cause the collapse of a structure. For the first time, we have shown that fire can induce a progressive collapse." Shyam Sunder - August 21, 2008 NIST Media Briefing

"The extensive three-year scientific and technical building and fire safety investigation found that the fires on multiple floors in WTC 7, which were uncontrolled but otherwise similar to fires experienced in other tall buildings, caused an extraordinary event. Heating of floor beams and girders caused a critical support column to fail, initiating a fire-induced progressive collapse that brought the building down." -NIST WTC7 Report Press Release Nov 20 2008

Considering NIST has discovered a "extraordinary event" which can lead to the total destruction of a 610ft steel framed building, one would think not releasing the data "might jeopardise public safety".
