Ok, first off thank you for making me read the official reports.
The report you linked only briefly mentioned WTC 7. There was a companion report that focused fully on it called NIST NCSTAR 1A, located here:
https://ws680.nist.gov/publication/get_pdf.cfm?pub_id=861610
I'm half way reading the report and so far it's actually strengthening my case to be asking questions, especially as there is a video of the guy, Larry Silverstein who jointly owns the building, that directly contradicts the report.
The only part, and interesting information about WTC 7, in the report you posted was that all the alarm system was off due to a test that day. This means the entire system was disabled through-out the building and if a sprinkler did go off, which some did according to the report, the operator at the console wouldn't see an alarm going off.
I have 10 bits of interesting information so far and I'm not even half way through. It seems like an honest report. But even in the report they don't understand how a regular fire caused by debris from WTC 1 could collapse the building. The report even says that its the first known instance of a total collapse of a tall building due to fires.
According to a simuilation hypothetical, no blast played a role in the collapse of WTC 7.
So the report leaves it open as a mystery.
Meanwhile we have Larry Silverstein saying;
I think that contradicts what the report says. It's interesting that Silverstein was a contributor (Silverstein Properties) to the report he's just gone against. He's solved the mystery!
