What Did Not Happen
This part is relatively easy. If, for example, it is known that aviation fuel in an oxygen-starved atmosphere burns at less than 500 degrees celsius, while structural steel loses little of its integrity until the temperature exceeds 1000 degrees celsius, there is good reason to examine all available evidence concerning the collapse of the World Tade Center twin towers, not to mention WTC Building 7. Such evidence must be evaluated and documented and all anomalies and/or physical impossibilities clearly delineated. If persuasive, the conclusion must be drawn that the buildings in question were demolished by other means. (See Derek Grimmer, for example – Calculations on the Possible Use of Thermite to Melt Sections of the WTC Core Columns.)
