I think people might be over stating things here. The towers certainly didn't fall within their "footprints". The debris was scattered over a sizable area, and many buildings suffered extensive damage due to the collapse, most noteably WTC7.
My only problem is the notion that a "controlled demolition" would have been much more controlled. The fact is, aside from the initial tilt, the buildings both fell down. Straight down.
I think the debris pile and damage to the surrounding buildings would have been the same had the towers actually been CD'd.
I say this knowing full well that a CD would have caused the blow out of almost all the windows in lower Manhattan. But we're playing dumb here so bare with me.
In an actual controlled demo, the core would have been the first to go. This would have minimized the lateral ejection of material. The goal would have been to "implode" the buildings as much as possible to avoid damaging the surrounding buildings.
Due to the height of the buildings and their unusually small footprint (in relation to the height of course) I'm not certain a professional (using thermite, from the top down :rolleyes) could have brought down the towers any better, or with less damage, than we saw on 9/11.
That being said, I'd caution against arguing the whole "footprint" thing with the truth movement. Given the lattitude the truth movement is taking the end result really does resemble a CD (in truther land)
I'm only saying this after reading the "Hardfire" thread. In that, realcddeal or tony as he likes to be called, is apparently denying there was any initial tilt. This denial serves two purposes in my opinion. 1) He's convinced the video evidence shows the upper block is being destroyed by explosives in the first few seconds, and uses the dip in the roof line as proof. This is contrary to the evidence that the dip is a result of the camera angle and the "tilt" observed in the upper block. Accepting the tilt means accepting the fact that the core was not blown out and the upper section did not "turtle" in upon itself. 2) The tilt is the main reason the debris did not fall perfectly within the footprint. Most of the lateral ejection of heavy material (exterior sections) can be attributed to the tilt of the upper section as it tucks behind the lower section. Without the tilt the exterior falls straight down due to gravity in a neat pile at the foot of the building. This, in the truther mind, means that the debris ejected outside the footprint got there by some external force other than gravity. I'll let you guess what that force might be. And I'll give you a hint, it isn't "On Angels wings"
