In test networks, sure. My point stands, the idea there were no planes is just monumentally stupid. There are multiple, independent sources for video of the event, countless first hand witnesses, etc. etc. I am not saying they didn't twist it to fit a narrative, or perhaps even turn a blind eye to, or even assist it. But planes hit those buildings. Maybe, just maybe, there were some incendiary devices. Kinda looked like it, but i can't point to one single definitive proof of it, and the things purported to be proof, generally, are speculative, entirely unscientific, or fraudulent. One thing is for sure, hierarchical government structures enabled this, were instrumental in empowering the MIC to invade Afghanistan for profit, driving OBL to the extremes he went to in order to stop it.
