... a few failing truss anchors would cause an entire floor to "unzip" and this would initiate a progressive "pancake" collapse.
So I'd suggest that one guy with one tank could carry in enough explosives or thermite cutting charges to do the job by that mechanism for each building. But of course explosives could also have been smuggled in inside copy machines, office furniture, cases of paper, construction materials such as drywall mud or paint or fireproofing compound, construction tools such as air compressors.
Dr. Van Romero opined that a few charges in a few key places could bring the entire building down. He didn't put a number on it and didn't identify the places.
I'm not aware that any serious study has ever been done of how many charges it would take. Many of the controlled demolition theorists may be inclined to exaggerate the complexity of the project because some of them clearly like the idea of a vast conspiracy with unfettered access to the buildings.
Food for thought:
Most of the main structural columns in the towers were accessible for most of their length from inside the towers' 15 miles of elevator hoistways. During the 9 months before 9/11 a massive elevator renovation project was going on, so the presence of parties unknown in the elevator shafts would not have been particularly noteworthy. On the morning of 9/11, 80 of these elevator mechanics gathered in the lobby. They knew people were trapped in elevators. They knew the people could not get out because the mechanics had themselves just installed interlock devices to prevent people from opening the doors for themselves. And yet in spite of the fact that elevator mechanics have a culture of doing rescue operations, all of these 80-something guys ran away. Not one of them died on 9/11. I'm not suggesting that they planted bombs. I am suggesting that possibly they sensed that something was not right--perhaps they'd heard noises or seen lights or found evidence of work going on when they weren't there. They should be interviewed.
NIST claims that WTC7 fell down after part of the 13th floor fell down and initiated a chain reaction. FEMA tells us that floors 14, 15, 16, and 17 were vacant.
