Are you kidding me? Are you unaware that there are hundreds of first responders who question the official story? If you watched any of the linked videos, you would see them. On the day of 9/11, describing what they saw to journalists, and since that day, more and more have come forward.
I know you think you’re terribly smart, but you haven’t done your due diligence. The thing about research is this: you can’t just go to the official sources, because there are hundreds if not thousands of reasons for them to be untrue. It has happened even in peer reviewed science journals. Bullshit studies, supported and promoted for political and economic reasons. Look at early AIDS research for one example of the bs You need to look at ALL the evidence (there is plenty of expert research that is not official. Look at the debunking of the NIST report), and then come back and make an intelligent argument for the official story.
