Believe is not involved here. It's a matter of knowledge about the parade of witnesses telling to the camera their experience of the plane approaching on a path that is incompatible with it causing the damage at the Pentagon.
This evidence exists despite all attempts to bury it in smoke and mirrors. My four options generally cover the possible explanations, poorly worded or not.
No, they don't, because a fifth explanation has been repeatedly stated here. Your claim that it hasn't been proven is irrelevant; the very fact that you're suggesting four valid options indicates that none of those has been proven either.
Your four options were:
1) The witnesses are all mistaken in the same bizarre way.
2) They are actors payed by CIT to pose as the real on record witnesses.
3) They are part of a disinfo operation that fooled CIT.
4) They honestly and accurately describe what they have witnessed.
Option (1) is the closest to reality, but it's still not an accurate description of the consensus because even the NoC flight paths don't agree with one another; they are quite literally all over the map. The consensus is that all the witnesses honestly and accurately described their
recollections of what they witnessed, that these recollections vary due to the imperfect nature of memory, and that CIT has carefully selected a subset of these random variations and ignored all others. It's a classic example of confirmation bias and special pleading; any excuse to ignore SoC testimony is siezed upon, as is any excuse to misrepresent SoC testimony as NoC, yet no similar critical examination of NoC testimony is even attempted despite the fact that in at least one case the NoC flight path is physically impossible for the witness to have seen.
So the response I think we agree on, whether you choose to acknowledge it or not, is:
5) Their accounts vary due to imperfect recollection, and CIT have cherry-picked and misrepresented accounts in order to give the false impression that all witnesses agree on a NoC approach.
Now, please feel free to go on pretending that nobody actually believes this, and rationalise it however you like. Just be aware that we all know you're denying the reality of this specific issue, which makes it all the more likely that you're in denial about a whole load of other things.
