content: You can see a likely reason why the NIST timeline begins noticeably before the collapse appears to begin in Part III at 8.50, while the narrator compares that timeline with a completely different angle obscuring the structure which shows the first signs of the collapse.  I am not convinced the series you began your post with is being honest with me for that reason.  It seems to me the narrator is guilty of exactly what he is accusing NIST of, searching for ways to manipulate evidence to fit a predetermined theory.    You cannot find the truth by claiming to know it before your search begins.
