Two weeks after 9/11, engineers Pablo Lopez and Andrew Pontecorvo are walking in the B2 basement level at the ruins of the World Trade Center, towards where the North Tower stood. They discover a “solid, rocklike mass where the basement levels of the tower had been,” and see “the recognizable traces of twenty floors, very much like geologic strata revealed by a road cut, compressed into a ten-foot vertical span. In one place, the steel decks of half a dozen floors protruded like tattered wallpaper, so close together that they were almost touching where they were bent downward at the edge. Nothing between the decks was recognizable except as a rocky, rusty mishmash. In a few places what might have been carbonized, compressed stacks of paper stuck out edgewise like graphite deposits.” As New York Times reporters James Glanz and Eric Lipton describe, Lopez and Pontecorvo have found “where the vanished floors [of the tower] had gone. They had not just fallen straight down. The forces had been so great and the floors so light that they had simply folded up like deflated balloons.” Furthermore, they see the massive core columns of the tower, which are over two feet wide and made of four-inch thick steel plate, appearing to have suffered “a compound fracture: the upper sections looked as if they had been kicked, with incalculable fury, about a foot south of the sections they were resting on.” Lopez remarks, “Can you imagine the force?” [Glanz and Lipton, 2004, pp. 292-293] At some later time, ironworker Danny Doyle, who is also working at Ground Zero, finds that floors of the South Tower have been compressed into a formation like what happened with the North Tower’s. He discovers “a distinct mound of debris set into the pile, about six feet high, with strands of wire and pieces of rebar sticking out. It looked like layers of sediment that had turned into rock and been lifted up on some mountainside.… Here were ten stories of the South Tower, compacted into an area of about six feet.” [Glanz and Lipton, 2004, pp. 310]

A leading current affairs program on Dutch television says that 9/11 was a governmental conspiracy. The program is entitled “Zembla: Het complot van 11 september.” Zembla is a weekly investigative report shown on the public broadcasting network VARA. (A version of the program with English subtitles is available on Zembla’s website.) The program’s highlight is an interview with Danny Jowenko, a Dutch expert and industry professional in demolition. When shown a video of the collapse of Building 7 of the World Trade Center, he concludes that it is undoubtedly the work of a professional demolition team. [Vara, 9/10/2006]

In a reply to criticisms of its World Trade Center investigation, the National Institute of Standards and Technology (NIST) admits that it is unable to fully explain the total collapse of the Twin Towers on 9/11. NIST’s letter is a response to a “request for correction” letter sent to it five months earlier by Bob McIlvaine and Bill Doyle, who both lost family members on 9/11, along with scientists Kevin Ryan and Steven E. Jones, architect Richard Gage, and the group Scholars for 9/11 Truth and Justice. This letter made several assertions about NIST’s final reports of its WTC investigation, and suggested they had violated the Data Quality Act and NIST’s information quality standards. NIST’s reply denies the requests for corrections. However, it also mentions, “[W]e are unable to provide a full explanation of the total collapse” of the World Trade Center. [National Institute of Standards and Technology, 9/27/2007 pdf file] In its final report on the Twin Towers collapses, released in October 2005, NIST admitted that its investigation did “not actually include the structural behavior of the tower after the conditions for collapse initiation were reached and collapse became inevitable” (see October 26, 2005).
