Conspiracy theories from the fringe: Was 9/11 A Contract Hit Paid For With Billions Of Tax Dollars?

"History shows that terror acts can be paid contract hits. We live in the age of "military contractors" who seem to be willing to do anything for the right pay.
Several powerful neocons control vast funds in the Pentagon: Paul Wolfowitz, Dov Zakheim and others. $1 trillion of Pentagon money [is] unaccounted for.
Rabbi Dov Zakheim was also corporate vice president of System Planning Corporation who manufactures a highly sophisticated technology that enables an operator to fly by remote control eight different airplanes at the same time, from the ground or the air.
Billions of dollars and many people and months would be needed to acquire and operate this equipment as well as to set up the controlled demolition of the WTC buildings 1, 2 and 7.
Did the neocons--who have exploited 9/11 to the max--also divert billions of Pentagon tax dollars to pay "contractors" for the biggest contract hit of all times? Was 9/11 the work of hi tech hitmen?"
