Explained many times, you just can't prove any claims for any of your conspiracy theories.
But hey, been a while since I read what YOU believe happened to building 7. Entertain us with your engineering genius.
Meanwhile, 'Occam's Razor: Bad sprinklers and no decibel level recorded that would confirm a controlled explosive detonation.
Ya got nutthin' shadetster, other than another bat-shit crazy conspiracy theory........... 'demolished'.

Quote:The report determines that the actual culprit in the collapse was the combustion of ordinary building furnishings: "These uncontrolled fires had characteristics similar to those that have occurred previously in tall buildings." If the sprinkler system in WTC 7 had been working, it is likely that "the fires in WTC 7 would have been controlled and the collapse prevented."
The report also suggests that current engineering standards for coping with fire-induced thermal expansion need to be re-examined, particularly for buildings like WTC 7 that have long, unsupported floor spans.
A key factor in the collapse, NIST concluded, was the failure of structural "connections that were designed to resist gravity loads, but not thermally induced lateral loads." According to Sunder: "For the first time we have shown that fire can induce a progressive collapse."
Spurred by conspiracy theorists' questions, investigators did look specifically at the possibility that explosives were involved.
"Hypothetical blast events did not play a role in the collapse of WTC 7," the report states, adding that investigators "found no evidence whose explanation required invocation of a blast event."
Moreover, the smallest charge capable of initiating column failure "would have resulted in a sound level of 130 dB [decibels] to 140 dB at a distance of at least half a mile." Witnesses did not report hearing such a loud noise, nor is one audible on recordings of the collapse.
