First, picture the demolitions teams wiring up the World Trade Center towers with explosives prior to the attack. Obviously you couldn't do it during business hours, since it'd be kind of hard to explain to the 100,000 people who worked at or visited the WTC towers on any given day why you had a huge chunk of wall torn out and were wiring up a bomb on the steel beams there.
I mean, keep in mind, I don't know how big of a job that would be (no one has ever demolished a building that size before) but a building just half the size of one WTC tower took 4,000 separate charges to bring down. Four thousand.
That job took seven months of prep work... and they had the run of an abandoned building, without having to hide their work from 100,000 people every day. Our demolition crew, on the other hand, can work only at night and has to spend the last bit of every shift carefully repairing the wall and hiding any evidence of charges or detonators as not to be discovered during the day.
Huge teams of demolitions experts, who had no problem wiring a building full of innocent New Yorkers to explode, hired in secret, worked every night for what had to be a year (and that's only if they had a big enough crew) placing maybe 10,000 separate charges in each tower and another few thousand in WTC 7 (the smaller WTC tower that also collapsed, later in the day on 9/11).
And nobody notices.
That's right. That's the theory they're putting out there. 100,000 DVD's they've sold with this.
Truckloads of bombs, dozens of mysterious workers, going in and out of the building, night after night. Security at the building doesn't catch them, Port Authority Police don't catch them, random eyewitnesses who stumble across the operation and call the cops don't catch them, maintenance workers who stumble across wet paint and repaired walls and bits of strange wire don't catch them, security cameras don't catch them.
The bomb-sniffing dogs who were brought in from time to time (remember, these buildings were bombed by terrorists in 1993) who are trained to find even one bomb, fail to notice the 10,000 bombs lining their building.
