Global collapse sees the "downward movement of a single unit" as described by NIST. Those are their words. According to NIST, the unit comprises the top 33 floors of the building so it's very large. They describe no further damage to that unit other than to say it kinked slightly. It could have course been more than 33 floors as only their own hypothesis claims the failure started below floor 14 - it could have been on floor one.
The video evidence shows this as well - as clear as day. The walls are vertical and the roof and windows are horizontal with some slight distortion which is to be expected. The east and west sides fall at the same time and speed as the centre of the north wall so it is symmetrical. From one angle the building appears to lean ever so slightly but it is by a degree or two so is to be expected. You cannot argue with this because it is there for all to see. The building falls straight down.
As for centre of gravity, I'm not sure what you mean. Gravity acts downwards which means for a building to fall straight downwards as a single unit it must lose all support below it at once. If any support remains off centre to the centre of gravity then the building will start to rotate sideways and topple over. WTC7 didn't rotate (except by a degree or two as I say above) so that means the support across the entire floor plan had to have been lost for it to fall DOWNWARD as a single unit. You are right to say the building is a set of interconnected parts so how on earth can all the interconnecting parts on one level disappear to allow the building to drop DOWNWARD as a single unit. Remember, if any of those interconnecting parts stay intact, even for a split second, they will offer support and the building will rotate and topple over. No fire in any high rise steel building has ever achieved the effect of instantaneous loss of structure across an entire level. CDs have.
Your tree analogy is quite interesting. When cutting down a tree, will it drop straight down when the chain saw cuts through the trunk or will it topple over sideways. The latter of course because unless the chain saw can cut through the trunk fast enough to remove a section of said trunk in an instant, the tree will rotate rather than fall downward. A building is no different except that a tree has a solid structure and a building doesn't. The structural principle of moving downward versus rotation is the same though.
Let me get this straight.
You want to believe that the people who supposedly planned 9/11 wanted the destruction of WTC7 to LOOK like a controlled demolition by bringing what was left of WTC7 straight down into it's own footprint???? You mean to tell me that after years of planning this supposed fiasco, they wouldn't have thought to NOT bring it down that way?
Your logic is dizzying to say the least...
Let's look at another part of your logic. Do you mean to tell me that when structural components fail, the load they supported as a whole is NOT transferred to the remaining structural components? So you believe that it is IMPOSSIBLE for the remaining structural components, already in a weakened state due to heat/thermal expansion, could not have surpassed their load supporting capacity in a way to cause the global collapse of the remaining structure?
