All undertakings that involve planning by two or more people, and which planning is not openly publicized ARE conspiracies, by definition.

The 911 attacks were unquestionably the results of a conspiracy. The only question is, "a conspiracy on the part of whom?".

A 47-story modern steel frame building does not fall in the fashion that Building 7 did on account of a few small, scattered fires in a few scattered locations on some of its lower floors. It falls in that fashion only by controlled demolition. A controlled demolition of that sort takes several weeks for demolition experts to plan and set up, not a few hours.

That suggests a conspiracy, and not by Al Queda, needless to say.
