Feel free to review the Nist study.How do you explain the physics of two aircraft collapsing three steel-framed skyscrapers into their footprints?
How do you explain the motivation behind concocting an incredibly complex scheme rather than a simple one? Why even involve the planes at all? Just hook up explosives in the basement and blame trucks parked in the garage as in the 1993 attempt? Nah...let's involve thousands of people at the airlines, FAA, air traffic control, the military, the CIA, the insurance companies (policies on the planes)...and on and on.
