As I've previously stated on other threads (on several occasions), I am a building/demolition contactor and I have personally imploded several steam stacks, chimneys and multi-storey structures. There is no way that the U.S. government (or anyone else, for that matter) could implode the W.T.C onto its footprint without raising the suspicion of its occupants. The building would have to be gutted, walls removed, beams weakened with oxygen lances and RDX charges embedded and wrapped around the superstructure stanchions. Not forgetting the miles of detonator cord. Furthermore, such a conspiracy - which is physically impossible - would require the hundreds of men needed to keep silent about their murderous intentions.
