I am confident planes did not hit the buildings, and that the imagery shown to the world of planes hitting buildings was faked. I believe this for very specific reasons from my own personal analysis of the visual evidence that was later confirmed by others’ work.
The controlled demolition seems obvious to the eye but I’m not an engineer so I rely on the analysis of others to believe that.
I believe the towers were mostly hollow, empty propaganda/tourist pieces like the Eiffel Tower, and I base that largely on Occam’s razor reasoning and the evidence marshaled by a guy named Steve De’ak and others at letsrollforums (which is sadly no more)
