Over the past 15 years many highly respected academics and experts have come forward to challenge the official narrative on the collapse of the WTC towers forwarded by the U.S. government. The official government position holds that the collapse of all three towers was due to intense heat inside of the buildings. But a new forensic investigation into the collapse of the three World Trade Center towers on 9/11, published in Europhysics News – a highly respected European physics magazine – claims that “the evidence points overwhelmingly to the conclusion that all three buildings were destroyed by controlled demolition.” While many in the mainstream have attempted to label anyone questioning the official narrative as a “tin foil hat” conspiracy theorist, many highly respected experts have come forward to lampoon the idea that the buildings collapsed due to the intense heat and fires following two terrorist-directed plane crashes. “Given the far-reaching implications, it is morally imperative that this hypothesis be the subject of a truly scientific and impartial investigation by responsible authorities,” the four physicists conclude in the damning report. The new study is the work of Steven Jones, former full professor of physics at Brigham Young University, Robert Korol, a professor emeritus of civil engineering at McMaster University in Ontario, Canada, Anthony Szamboti, a mechanical design engineer with over 25 years of structural design experience in the aerospace and communications industries and Ted Walter, the director of strategy and development for Architects & Engineers for 9/11 Truth, a nonprofit organization that today represents more than 2,500 architects and engineers. The comprehensive study in Europhysics News directly challenges the official narrative and lends to a growing body of evidence that seriously questions the veracity of the government narrative. In 2002, the National Institute of Standards and Technology remarked that the case was exceptionally bizarre. There were no other known cases of total structural collapses in high-rise buildings caused by fires and so it is deeply unusual that it should have happened three times in the space of one day, noted NIST. Official investigations have never been able to thoroughly and coherently explain how this might have happened and various teams tasked with examining the collapse have raised difficult questions about the veracity of the government’s story. Perhaps most damning of all, the experts claimed that after a thorough forensic analysis of video footage of the building’s collapse, it revealed signs of a controlled implosion. Additionally, Jones has co-authored a number of papers documenting evidence of unreacted nano-thermitic material in the WTC dust. The authors of the study note that the buildings fell with such speed and symmetry that they there was no other feasible explanation for the sudden collapse at free-fall speeds – directly refuting studies that attempted to debunk the idea that the building fell without resistance. These respected experts’ new forensic analysis only adds to the growing movement of people calling for a new and impartial investigation into the collapse of the World Trade Center. Revealing the scope and breadth of public disbelief in the official government narrative surrounding the events of 9/11, even presidential candidate Jill Stein has recently called for a new investigation.

How did they know to plant the explosives exactly where the planes hit?
I've asked that question a hundred times. Along with many others like why would there be a need to fly planes into the buildings in which they knew were just going to be blown up with explosives? All you ever get is it is irrelevant. There is no point arguing with kooks.
I've asked that question a hundred times. Oh for pete's sake - they didn't need to plant them where the planes hit. ...why would there be a need to fly planes into the buildings in which they knew were just going to be blown up with explosives? Seriously? They needed to blame the attacks on Iraq and bin Laden. Who would ever believe that a guy on a dialysis machine and living in a cave would be able to pull off something like that? Use your head man!
It is quite obvious from any video that the collapse initiated at the point of plane impacts.
I'm sure you believe that. More's the pity. High-Velocity "Demolition Squibs" Are Visible in the Twin Towers' Collapses In discussions of the collapses of the WTC skyscrapers, the term has been appropriated to describe the physical appearance of puffs or jets of dust emerging from buildings during a demolition, caused by the detonation of explosive charges. Several such "squibs" can be seen in videos and photographs capturing the collapses of the North and South Towers. It has been suggested that the evident squibs could have been added to the photographs and videos after the fact, given that much of this evidence has found its way onto the web via undocumented routes. However, the squibs show up in many diverse videos and photographs, and we have not been able to find any showing the squibs to be absent. A conspiracy of incredible proportions would be required to forge such convincing evidence of squibs in such diverse sources. Q: What caused the "squibs"? Could they have been just puffs of dust being pushed out of the Towers by falling floors? Are they visual evidence of explosive charges? A: The isolated ejections 20-60 stories below the demolition front appear to be composed of pulverized building materials, including concrete. There was no known mechanism by which pulverized building materials being created up at the zone of destruction could have been transported so far down through the building and to the exterior. Air conditioning vents would not have tolerated such pressures, and there was no other "channel" in the building to deliver “compressed air”. Twin Towers' Rates of Fall Proves Demolition Each of the Twin Towers fell completely in intervals of time similar to that taken for a block of wood dropped from a tower's roof to reach the ground. A block of wood has about the same average density as the main components of the towers near their tops. In a vacuum, a block of wood (or lead) would take 9.2 seconds to fall from the tower's roof. In the air a block of wood, say ten inches on a side, might take 50 percent longer than in a vacuum. Fifteen seconds, a good estimate for the total time of collapse of the North Tower, is about the time it would take our block to fall from the roof. The rubble from the Tower probably had similar average density to our block of wood, since the floor slabs consisted of corrugated sheet metal and lightweight concrete, and the perimeter steel columns were hollow with walls only 1/4th inch thick at the Towers' tops. Air resistance alone could account for the slowing of the falls to the point where each Tower took about 15 seconds to completely come down. The official story requires that more than air resistance was slowing the descents. The falling rubble would be having to crush every story below the crash zone -- ripping apart the steel grids of the outer walls and obliterating the steel lattice of the core structure. The resistance of the intact building itself would be thousands of times greater than air resistance. If air resistance is able to increase total collapse times by even 20 percent, then shouldn't the addition of the resistance of the buildings themselves increase the time several thousand percent, to at least tens of minutes? Of course the idea of a collapse lasting minutes is absurd. So is the idea of a steel frame building crushing itself.

Images like this one reveal that the squibs were not merely puffs of air, as they have the same hue and consistency as pulverized solid building materialsMultiple analyses have shown that the ejection speed of the squibs was too high, at 100+ mph, to have been the result of air pressure. These are explosive speeds. They have also been clocked at 160 to 200 feet per second.
