As having brought down a few silos I can tell you a tall structure tends to fall straight down. watch the video of the collapse and you can see that they fall from the top. The weight crushes the lower floors and down it goes.
there is a saying in the science community "The simple answer is usually the correct one". Plane hits building, building falls down.
conspiracy theories are usually pretty stupid if you ask me.
evenso I will continue to expand my collection of guns just in case
