As your own eyes witness — WTC Building #7 (a 47-story high-rise not hit by an airplane) exhibits all the characteristics of a classic controlled demolition with explosives: (and some non-standard characteristics)

Rapid onset of “collapse”

Sounds of explosions at ground floor - a full second prior to collapse

Symmetrical “collapse” – through the path of greatest resistance – at free-fall speed

“Collapses” into its own footprint – with the steel skeleton broken up for shipment

Massive volume of expanding pyroclastic dust clouds

Tons of molten metal found by CDI (Demolition Contractor).

Chemical signature of Thermite (high tech incendiary) found in solidified molten metal, and dust samples by physics professor Steven Jones, PhD.

FEMA finds rapid oxidation and intergranular melting on structural steel samples

Expert corroboration from the top European Controlled Demolition professional

Fore-knowledge of “collapse” by media, NYPD, FDNY

And exhibited none of the characteristics of destruction by fire, i.e.

Slow onset with large visible deformations

Asymmetrical collapse which follows the path of least resistance (laws of conservation of momentum would cause a falling, to the side most damaged by the fires)

Evidence of fire temperatures capable of softening steel

High-rise buildings with much larger, hotter, and longer lasting fires have never “collapsed”.

As seen in this revealing photo, the Twin Towers' destruction exhibited all the characteristics of destruction by explosions: (and some non-standard characteristics)

Destruction proceeds through the path of greatest resistance at nearly free-fall acceleration

Unnatural symmetry of debris distribution

Extremely rapid onset of destruction

Over 100 first responders reported explosions and flashes

Multi-ton steel sections ejected laterally 600 ft at 60 mph

Mid-air pulverization of 90,000 tons of concrete & metal decking

Massive volume of expanding pyroclastic-like clouds

1200-foot-dia. debris field: no "pancaked" floors found

Isolated explosive ejections 20 – 40 stories below demolition front

Total building destruction: dismemberment of steel frame

Several tons of molten iron found under all 3 high-rises

Evidence of thermite incendiaries found in steel & dust samples

FEMA steel analysis: sulfidation, oxidation & intergranular melting

No precedent for steel-framed high-rise collapse due to fire

And exhibited none of the characteristics of destruction by fire, i.e.

Slow onset with large visible deformations

Asymmetrical collapse which follows the path of least resistance (laws of conservation of momentum would cause a falling, intact, from the point of plane impact, to the side most damaged by the fires)

Evidence of fire temperatures capable of softening steel

High-rise buildings with much larger, hotter, and longer lasting fires have never “collapsed”
