I'm no engineer and maybe have no right to say anything, but take a look at the thickness of the outer steel beams of the twin towers, and the relatively small distance between beams, not to mention the inner steel frame around the elevator shaft. Big difference between cinder blocks and high grade super thick sreel frames, not to mention one of the videos they showed, the airliner as well as it's wings cutting right into the building and then the nose the jet coming out the other side of the building with no damage. Respectfully,Tri-simulating that. And then there's the fact that jet fuel Burns at well below what it takes to melt steel, and burns off rapidly, seems to me if one tried really hard they could explain the building collapsing above where the planes hit, but what about the rest of the building below? Not to mention falling straight down, not leaning over, at near Free Fall speed as you alluded to. Then there's steel framed,high-rise building 7 that collapsed that day, only had small office fires, not hit by a plane, which did collapse at freefall speed, straight down into its own footprint. Yikes! Is it any Wonder many don't believe the government narrative,yet there are many who don't question, and I question them not questioning it. It's almost a great of a Marvel, people believing the government's narrative, then it is to believe that three hijacked airliners stayed in the air for an hour and 20 minutes, and not one fighter jet intercepted the hijacked planes.
