The twin towers were undergoing an elevator modernization program in the nine months prior to the big shabang. That would have given the perpetrators unlimited access to set charges on the steel infrastructure with the cover of the "elevator renovation".
They pretty much shoot down the theory that the building was rigged for demo when it was built.
Thermite was definitely found in the dust/smoke. Chain of custody seems to be intact.
Tom Sullivan:
A former demolitionist, he states definitively that demolition brought those buildings down. Responding to callers question as to why the twin towers seemed to blow apart as opposed to building 7 which simply dropped he said that the the Twin Towers were pulverized because they required more explosives within the infrastructure to bring effectively bring it down into the smaller sections that could be hauled off more easily. "It doesn't take that many "decks" just to bring a buildind down. A contractor will load more decks just to break up the rubble into smaller pieces. Building 7 didn't require so many decks... 1 or 2 decks and you could probably bring this building down. But the twin towers presented a different problem because of all that inside structural steel. You had to really, really attack this problem differently, and a lot more explosives, which leads to all the pulverization... The problem with the towers was that they were so much more robustly built, (which is a problem for the official story) the inside core had so much more structural steel, you would've had to use a lot more explosives and ways, you had to really load the decks to bring those buildings down."
Richard Gage:
"... 90000 tons of pulverized concrete. A fine powder all over Manhatten, including metal filings from the steel..."
That story about the Ace elevator guys taking off is interesting. Who owns Ace?

A positive note is that in spite of the fact that ACE Elevator Co. had 88 people working throughout that WTC buildings, maintaining and modernizing the elevators when the attack occurred, none were hurt. Aside from bearing emotional scars that will take years to heal, they, as well as Otis Elevator Co. personnel that were working in the 7 WTC Building and the Schindler Elevator Corp. personnel working in the Marriott Hotel and at the Pentagon are all OK.
