On Friday 29th June John Bursill spoke by phone with a several staff members of the Faculty of Architecture, University of Sydney. The purpose of John’s call was to share information and ask for opinions from appropriately qualified professionals about the compelling evidence which shows that the three sky scraper collapses in New York which occurred on the 11th September 2001 were deliberate demolitions rather than merely the unfortunate consequence of the impact of fuel-laden jet airliners.
Among those John spoke with is Dr. David Leifer, Senior Lecturer and Coordinator of the Facilities Management Program. Dr. Leifer expressed his agreement with one of the central claims of the 9/11 Truth Movement, namely that the manner in which the WTC towers collapsed, does not accord with the official explanation endorsed by the National Institute of Standards and Technology (NIST) of a purely gravity driven collapse initiated by structural failure. Dr. Leifer later confirmed his views in an email to John, which we present below:
The frequently repeated TV images of the aircraft slamming into the World Trade Centre overwhelmed any thoughtful response. Naturally, the collapse of the buildings was attributable to this traumatic event.
It was only later when pictures emerged showing the inappropriate damage to the Pentagon – reported to have been caused by a large aircraft crashing through several layers of external wall – that professional doubt was aroused in my mind. Thereafter, The fall of the World Trade Center video showed the side of one tower ‘unzipping’ along one side of a damaged floor. My knowledge of structure and dynamics told me that unless the other sides simultaneously ‘unzipped’ there was no way that the tower would have ‘pancaked’ onto it’s own footprint: it should surely have toppled outwards. That both towers did the same was just too improbable to be plausible.
Hence I am anxious to learn what really happened.
