This is the building 7, the 3th building that was blown up, controled, that day. An explosion expert from Holland/Netherlands was watching this clip and said: Yes: this is controlled demolition, no doubt about that! He died under mysterious circumstances a little later. Hit with his car a impossible tree in the province of Zeeland in the Netherlands and died on impact. A tree that was standing at the other side of the road, with such a force that the care was enormously damaged? Hmmm? One of the several impossible deads of the withnesses who stated opposit opinions than those of NIST researchers.
