What I don't understand is how can buildings 3, 4, 5 and 6, hit by debris form World Trade Centre buildings 1 and 2 and burning aggressively exhibit evidence of normal destruction by fire, with steel frames still rising and concrete dissembled in a haphazard fashion, while building 7 - one football pitches' distance from WTC 1 & 2, not hit by a plane, disintigrated into its own footprint and crumbled into piles of dust.
