Why Indeed Did The WTC Buildings Completely Collapse?

This is former BYU Physicist Dr. Steven E Jones first paper on the WTC collapses. So far, no official investigation has seriously challenged his hypothesis that the Twin Towers and WTC 7 were brought down by explosives; specifically pre-positioned cutter charges.

Dr. Jones challenges serious investigators who wish to rebut his controlled demolition hypothesis - they must address thirteen reasons why he rejects the official theory, which asserts that fire and impact damage alone caused the collapses:

1) Molten Metal - Flowing and in Pools.

2) Observed Temperatures around 1000 degrees C and Sulfidation in
WTC 7 Steel.

3) Near-Symmetrical Collapse of WTC 7.

4) No Previous Skyscraper Complete Collapse Due to
Fires.

5) Plume-time During the Collapse of WTC 7.

6) Early Drop of North Tower Antenna.

7) Eyewitness Account of Flashes and Loud Explosions

8) Ejection of Steel Beams and Debris-plumes from the
Towers.

9) Rapid Collapses and Conservation of Momentum and
Energy.

10) Controlled Demolition "Implosions" Require Skill.

11) Steel Column Temperatures of 800 C Needed: A Problem in the Argument of Bazant and Zhou.

12) Problems in the NIST Report: Inadequate Steel
Temperatures and Tweaked Models.

13) NIST's Failure to Show Visualizations.
