Mark Weitzman, Simon Wiesenthal Center, challenged

Richard Gage, architect, has demanded a retraction of "false, defamatory, outrageous and insulting statements" made by Mark Weitzman of the Simon Wiesenthal Center who, in testimony before the Homeland Security Subcommittee on Intelligence, Information Sharing, and Terrorism Risk Assessment, referred to AE911Truth.org as an "Incubator of 9/11 Conspiracies and Disinformation".

Gage's letter to Mark Weitzman makes the following points regarding the World Trade Center:
- The destruction occurred with rapid onset, at virtually free-fall speed, and with radial symmetry.
- One hundred eighteen first responders described hearing, seeing and feeling explosions and seeing flashes of light at the onset of destruction.
- The concrete floors were almost completely pulverized into dust and gravel.
- The structural steel framework was largely dismembered into shippable lengths. Much of it was hurled outside the Twin Towers' perimeters, some as far as 500 feet away.
- Tons of molten metal were seen by FDNY and others, and was described as "flowing like lava" for weeks after 9/11, yet its existence was denied by NIST.
- FEMA documented structural steel samples showing evidence of rapid oxidation, sulfidation, intergranular melting, and partial evaporation – features which occur only with temperatures at least 1,000° F. hotter than office or jet fuel fires.
- Proven chemical evidence of thermate, an incendiary material which produces molten iron as its by-product, found on the columns and beams, previously molten metal, and iron-rich micro-spheres in the dust by Dr. Steven Jones (and corroborated by the USGS but never explained).

"These features are characteristic of controlled demolitions, and not office or jet fuel fires", says Gage.
