After MEDIA SCIENCE OF 9-11: Official investigative reports were considered "whitewash" to many deaf-ears. From Day 1- "Media rushed to tell you, “They knew it all."
Popular Mechanics responds with a scientific explanation for the collapse of WTC 7 with a team of experts: #
“What our preliminary analysis has shown is that if you take out just one column on one of the lower floors,” NIST lead investigator Shyam Sunder told Popular Mechanics, “it could cause a vertical progression of collapse so that the entire section comes down.” The tower wasn’t hit by a plane, but it was severely wounded by the collapse of the North Tower. Which is when the fires started.

Tower 7 housed the city’s emergency command center, so there were a number of fuel tanks located throughout the building—including two 6000-gal. tanks in the basement that fed some generators in the building by pressurized lines. “Our working hypothesis is that this pressurized line was supplying fuel [to the fire] for a long period of time,” according to Sunder. Steel melts at about 2,750 degrees Fahrenheit—but it loses strength at temperatures as low as 400 F. When temperatures break 1000 degrees F, steel loses nearly 50 percent of its strength. It is unknown what temperatures were reached inside WTC7, but fires in the building raged for seven hours before the collapse.2. The North and South Towers of the World Trade Center weren’t knocked down by planes—they both stood for more than a half-hour after the impacts. But the crashes destroyed support columns and ignited infernos that ultimately weakened—not melted—the steel structures until the towers could no longer support their own weights Evidence currently points to WTC7 also collapsing because fires weakened its ravaged steel structure.
3. Demolition experts tell Popular Mechanics that wiring a building the size of WTC7 for clandestine demolition would present insurmountable logistical challenges. That issue aside, there’s a clear-cut engineering explanation for why the building fell the way it did. Trusses on the fifth and seventh floors of the building were designed to transfer loads from one set of columns to another; with the south face heavily damaged, the other columns were likely overtaxed. In engineering terms, the “progressive collapse” began on the eastern side, when weakened columns failed from the damage and fire. The entire building fell in on itself as the slumping east side dragged down the west side in a diagonal pattern. Still, damage to the Verizon Building (see p. 21 of this report), directly west of WTC7, and to Fiterman Hall (see here) directly north, show that it was hardly an orderly collapse.
NIST is currently preparing its final report on the collapse of WTC7, which is expected to be released this spring. In order to address concerns of conspiracy theorists, the organization added “Hypothetical Blast Analysis” to its research, according to a December 2006 progress report. The report also points out that “NIST has found no evidence of a blast or controlled demolition.”* Significant findings which physics and demolition experts have said regarding WTC 7’s collapse, as detailed in the book...
