"Can the building really fall off an airplane that hits it on the 93rd floor?" Certainly. There were another 17 floors where the plane hit the building. As the columns gave way due to the massive damage and fire, these floors fell and caused a chain reaction that collapsed the building.
"You would fall STRAIGHT DOWN ???? That's not very curious about you ???" Of course they would fall down directly. The towers were not tilted after the impact, so the only external force on the building was gravity, which was just pulled down. Some debris from the upper floors fell outside the footprint of the building, as these floors were inclined.
"Tower 7 also falls without a plane" Hmmmm "Tower 7 was massively damaged by the falling debris of the main towers.
I looked at the footage as it happened. I read what numerous experts wrote. A French idiot with a YouTube video and no basic understanding of physics will change my mind.
If you think the US government is behind the attacks, be an idiot. If so, they hired the people who took over the planes. The whole BS of explosives (would have taken weeks to wire these buildings, someone would have noticed) and remote-controlled military aircraft, which are painted so that they look like passenger planes (not missing), are crazy.
