Really, dude, you can stop with the explosives horseshit. You need to watch that video closely. At the 2:10 time mark, you will clearly see a wide section of the perimeter wall from about a third of the way in from the left to the center begin to fall before the rest of the upper portion begins to collapse. There is no visible evidence whatsoever that an explosive detonation occurred, not at that moment or any time thereafter.
I think you are sadly mistaken . . .
