http://www.ae911truth.org/twintowers.phpThe architectural drawings of the WTC North Tower have been leaked from an individual associated with the Silverstein-Weidlinger Report. They reveal that the large box columns of the core maintain their 30"x16" and 52"x22" dimensions at least up through the 66th floor. They also indicate that most of the core columns would be easily accessed from the elevator shafts in order to plant explosives. We know that the elevators were being modernized by Ace Elevator during the 9 months prior to 9/11.
A March 2001 article in Elevator World describes contemporary work on the elevator system of the Twin Towers by Ace Elevator as
"one of the largest, most sophisticated elevator modernization programs in the industry's history." Elevator World, March 2001

Mechanics left towers before buildings collapsed
By Dennis Cauchon, USA TODAY
At the time the elevator mechanics left, dozens of people were trapped in stuck elevators. Other people lost their lives trying to rescue those trapped in elevators, including a mechanic from another company who rushed to the Trade Center from down the street.
The departure of elevator mechanics from a disaster site is unusual. The industry takes pride in rescues. In the Oklahoma City bombing in 1995, elevator mechanics worked closely with the firefighters making rescues.
http://www.usatoday.com/news/sept11/...tor-usat_x.htmOn Sept. 11, the mechanics left on their own, without instructions from police or fire officials. ACE Elevator supervisors say this was consistent with the emergency plan. All the mechanics survived. "We had a procedure. We had a procedure to follow, and they (the mechanics) followed it," Niederau says.
But the Port Authority says the emergency plan called for mechanics to stay and help with rescues. "The manuals consider many emergency scenarios and describe the role of the mechanics in detail in responding to them," Port Authority spokesman Allen Morrison says. "There was no situation in which the mechanics were advised or instructed to leave on their own. They were, depending on the situation, to be dispatched to various emergency posts or to respond to various pas
About 9:45 a.m., from the south tower lobby, Port Authority elevator manager Joseph Amatuccio radioed the ACE Elevator supervisors on their private radio channel. O'Neill recalls him asking: "Can you mobilize to come inside and see what's going on? Because I'm here with the fire department, and they're asking me questions I don't know."
O'Neill radioed John Menville, an ACE Elevator supervisor trained in rescues, and both tried to get back in the building. The supervisors had special ID badges with red stripes that allowed them behind police lines.
