Yes I have personally heard those tapes. First there were questions as to when to pull the building and there were several pauses followed by the order 'Yes pull it now'
The funniest thing (if funny can apply to media monopoly cooperation in criminal acts of mass murder) was when the BBC was reporting live the collapse of building 7 with their UK reporter on the scene while building 7 was still standing. Minutes later the building did fall.
Talk about propoganda over reaching. Next time media better keep it local.
