The WTC's were powered down for supposed cable upgrades for most of the weekend just prior to the 9/11 attacks. Some believe this was the ideal opportunity to wire the building for a controlled demolition.
Physicist Dr. Stephen Jones comments on his tests of metal he analysed (from one of the many memorials that were made from trade center scraps.)
Why was the steel from WTC collapses immediately shipped overseas to be melted down as scrap metal when it was key forensic evidence to learning how and why collapse happened.
Analysis of WTC's north tower collapse indicative of controlled demolition.
One of the WTC building's designers speaks of the specific ability of the WTC towers to take plane crashes. Recorded earlier in 2001, this man was lost on Sept. 11 when the towers fell.
Melted puddles of steel in the basements of all three buildings that fell. Five weeks later there was still red hot molten steel being pulled up by backhoes doing the cleanup. An uncontrolled fire can under the most ideal circumstances only reach 1700 degrees. Steel melts at 3000. Only explosives can cause that much heat. (Thermite, 4500 degrees)

No plane hit it at all. All three buildings fell at the rate of free fall (no resistance) Typical of a controlled demolition ONLY!
