The Destruction of the World Trade Center:

The Destruction of the World Trade Center:: "The Destruction of the World Trade Center: Why the Official Account Cannot Be True

Timothy Burke said that “the building popped, lower than the fire. . . . I was going oh, my god, there is a secondary device because the way the building popped. I thought it was an explosion” (NYT, Burke, pp. 8-9).
Firefighter Edward Cachia said: “It actually gave at a lower floor, not the floor where the plane hit. . . . [W]e originally had thought there was like an internal detonation, explosives, because it went in succession, boom, boom, boom, boom, and then the tower came down” (NYT, Cachia, p. 5).
The importance of these observations is reinforced by the fact that the authors of the NIST Report, after having released a draft to the public, felt the need to add the following statement to the Executive Summary:
NIST found no corroborating evidence for alternative hypotheses suggesting that the WTC towers were brought down by controlled demolition using explosives planted prior to September 11, 2001. . . . Instead, photos and videos from several angles clearly showed that the collapse initiated at the fire and impact floors and that the collapse progressed from the initiating floors downward.
Firefighters Burke and Cachia presumably now need to ask themselves: What are you going to believe, your own eyes or an official government report?
