David Chandler is a physics teacher, a Quaker peace activist, and an independent 9/11 researcher, active with Architects and Engineers for 9/11 Truth and on the board of the International Center for 9/11 Studies. He noticed that something was amiss with the way the buildings fell on 9/11 and did precise measurements of the motions associated with the building collapses and straightforwardly applied Newton’s laws of motion to show what this implied about the forces at work.
Chandler thinks that the free fall of the buildings is one of the clearest smoking guns for the use of explosives on 9/11. A paper describing his analysis can be found online at the Journal of 9/11 Studies. Chandler’s’ analysis proves that approximately 90% of the structural support had to have been removed from the North Tower for it to come down with constant downward acceleration as it did. Building 7 (the third building to undergo rapid, total destruction on the evening of 9/11) came down at absolute freefall as well so that also had to have its existing inner structure previously removed. Besides clarifying the dynamics of the building collapses, David Chandler has built a solid case that the official NIST (National Institute of Standards and Technology) investigation was an elaborate coverup, involving not just errors, but that it was fraudulent. Chandler is working on a documentary DVD that will tie together all of his work. Go to his website below and the numerous analytical videos posted by him on YouTube for more details.
