Also, I doubt it would have taken "months" to rig 2 buildings to explode, if you had enough man power and resources, both of which are readily available to both the terrorists and to the government.
It takes a tremendous effort to wire a building for destruction, more so than a weekend or two.
According to Brent Blanchard, an implosion expert with the demolition consulting firm Protec Documentation Services, virtually every building in the world is unique. And for any given building, there are any number of ways a blasting crew might bring it down. Blanchard notes the demolition of the Hayes Homes, a 10-building housing project in Newark, New Jersey, which was demolished in three separate phases over the course of three years.

To think that the WTC could be demolished with no one detecting the people working on the building for extended periods of time is, well, pretty silly.
