Sorry Einstein, but the last part of your sentence is your own spin on it and not at all an objective observation.   However, let us assume you are correct and let us assume that there were bombs in the building to bring it down. Using your supreme intellectual skills, explain to us how a bomb would "reverse" the "angle of momentum" of a disintegrating building.
