New NIST FOIA WTC Schematic Drawings

The National Institute of Standards and Technology (NIST) advised via a February 2, 2012 Freedom of Information Act (FOIA) reply that NIST will begin releasing all records in their possession obtained from the Port Authority of New York/New Jersey, Turner Construction and the New York City Department of Buildings used during their investigation of the collapses of World Trade Center (WTC) buildings 1, 2 and 7. The records of most interest obtained thus far consist of various schematic drawings of WTC 1 and 2.

Strength and Tenacity

Dear Aidan,

I just want to say I appreciate your hard work and point of view. The fact that you continue to release your valuable work through 9/11 Blogger is a testament to your tenacity.

Thank you Nick

duplicate files?

Thanks to Aidan Monaghan for your indefatigable work. A question: There are apparent duplicates of HVAC diagrams 57-77. Are there any differences in these files?

Unsure About Significance Of Duplicates

The files were copied from separate disks and each folder uploaded as is.

Thanks NM and NH
