It was pretty cringey, but at one point he said this regarding the crash at the Pentagon:
What are you going to research? There are multiple eye witnesses to a plane crashing into the pentagon on 9/11, the flight was tracked by Air Traffic Control as out of contact with them and off track headed to Washington DC and coming down at the Pentagon, there was an explosion at the Pentagon after witnesses saw a plane flying very low overhead and clipping a street lamp before it hit the Pentagon, the passengers from that flight are all dead. You have a news reporter who in the heat of reporting what happened mistakenly said a missile hit the Pentagon. There were not witnesses to that. If you want to find the truth, don't disregard every witness and piece of evidence to it.
I replied:
Those are certainly some things I could research. How about you learn why NIST's report is no good, and I'll dig into one or two of these things.
Any of y'all have any good resources for those topics he mentioned? Or alternative explanations? It's been a while since I've humored a 9/11 Official Narrative believer, but figured maybe I'd dip into it again.
I'm guessing it's probably unlikely you're going to change someone's mind, in the absence of irrefutable evidence. However, there are some things you didn't mention:
A photograph exists of a large "757-like" plane leaving the Pentagon airspace immediately following the explosion.
Where are the bodies, and wreckage? One such part found within the Pentagon was investigated by Christopher Bollyn: https://www.bollyn.com/is-the-pentagon-mystery-disc-from-a-global-hawk-2
Why was this event being filmed from a helicopter? Yes, filmed with a potato, but from a different angle, providing a bit more information. Is the side of the Pentagon being "painted" with a laser? https://defendingthetruth.com/threads/update-a-cruise-missile-slammed-into-the-pentagon-on-911.27808/
The news media frequently only shows the destruction after the floors collapsed, leaving a gaping opening on the side of the Pentagon. However, for the first few minutes, only a relatively small, round hole was evident following the impact.
The fireball from the explosion is identical to that from the detonation of other cruise missiles. I used to have a comparison photo, but don't know right at the moment which file folder I placed it in.
The taxi driver who had the light pole impale his windshield later recanted his story, claiming he was forced to report the incident under duress from some "scary people."
There's much, much more, but these are some of the more relevant bullet points.
