NIST did not inspect for evidence of a controlled demolition, because they say. "no one reported explosions".  How completely incompetent can an organization be?  This collapse looked exactly like a controlled demolition, and they simply dismissed looking for any evidence on the basis of a supposed lack of eye witness reports.

Well there were eye witnesses reporting explosions, and even Dan Rather commented live that day that the collapses all looked just like controlled demolitions.

NIST was either determined not to look for what they did not want to find, or they are the single most bumbling government organization ever, and that's really saying something.

But listen and watch for yourself, and then make your own call.
