The 9/11 Conspiracy - NOT A Conspiracy Video, What Do You Think?

It seems like most evidence on this to say that it WASNT a conspiracy is backing up the ideas that it WAS. That interview with the fireman hearing explosions, I'd never seen that before. Why did they find the need to mention that it was a firemen that heard it, and not the FBI like otherwise stated? It doesn't matter who said it, its just stating more that explosions were heard.
And anyway, who would know more about explosions, an FBI agent or a firemen? If id made this, I would have left that out because trying to state the fact that a firemen heard explosions instead of an FBI agent is just saying someone more accompanied to that type of thing believes there was explosives.

And that thing they said about the air being blown out of the windows because of the pressure/impact (sorry, I cant remember what was said exactly)...if something like that happened on a high floor, why would we see these bursts of air down at the very bottom of the building, and nothing in the middle? Surely you see the bits of air happening from top to bottom in that order because of the pressure, not air blowing out the windows towards the bottom and then in the middle

I think 9/11 was a horrible day, and we should remember everyone that was lost, and that the conspiracy people just need to give it a rest. Maybe something that happened in this country actually did happen, did they ever think about that?
