Abstract: The NIST investigation of the WTC building failures was extensive, but NIST did not substantiate its conclusions experimentally. On the contrary, many of NIST’s tests contradicted its conclusions. Furthermore, there are several examples in which NIST chose to manipulate input data, and then certify…
Abstract: In this paper, I call for a serious investigation of the hypothesis that WTC 7 and the Twin Towers were brought down, not just by impact damage and fires, but through the use of pre-positioned cutter-charges. I consider the official FEMA, NIST, and 9-11…
Abstract: One of the greatest mysteries of September 11, 2001 is the collapse of the Twin Towers. Claims that explosions contributed to the collapses were made on 9/11 and have persisted, but studies supportive of the U.S. government’s account of events have ignored or denied…
Abstract: This paper examines the elastic loading and plastic shortening phases of the columns of WTC 1 after impact of the upper 16 storeys of the building upon the lower storeys and its effect on the momentum transfer after the collision. An energy balance is…
