They're saying that WTC7 couldn't be a CD as it required time to plan and place explosives to bring it down.

This assertion is incorrect. None of the buildings collapsed at near freefall speed. This assertion has been rehashed for (literally) almost seven years with nothing new being brought forth. This claim can be made as many times as someone might care to but, it doesn't make the claim correct.
Here is the last detailed analysis I am aware of. It was updated in 2006.
Energy Transfer in the WTC Collapse
[edit on 26-7-2008 by SlightlyAbovePar]
First, it should be noted that the start of the major
oscillations in the seismic signature of each collapse event corresponds to the ground
impact of the main upper section of the towers.

actually, that is not an official paper.
dr. greening is 'free-lance' (at least, on the surface)
dr. greening entered the 911 fray with 'coincidental thermite' theory. he has also proposed spray on ammonium percholate (rocket fuel) 'fireproofing'.
from his paper, page two, erroneous thoughts:
First, it should be noted that the start of the major
oscillations in the seismic signature of each collapse event corresponds to the ground
impact of the main upper section of the towers.
newton's cradle illustrates what's wrong with this thinking. as soon as the broken off 'cap' hits the intact lower portion, the impact is translated directly into the ground. the only way this wouldn't be true, is if the whole tower deformed upon the initial impact.
another way to prove this is get an ibeam, spray-paint 'twoofer' on it, and stand it vertically on the head of a debunker. then strike it on the top with a 25 lb. sledgehammer, and then drop the hammer so it lands on his toe.
if he comes to, ask him what hurt more(ie. larger force translated into the dirt), the hammer on the toe, or the initial hammer strike.
now, if the debunker says he didn't feel the initial strike, then the greening logic stands.
really, the siesmic distrubances are more likely cause by the explosives, and that account for the 'short' times; 10 secs and 8.1 secs. the actual debris hitting the ground only cause negligible spikes.
and, speaking of the siesmic traces which were also feeding from the same energy trough as the collapse, deformation and comminution, notice they have been left out of (de)bunker logic.
notice how they like to ignore the INCREDIBLE amount of time and energy, and more importantly, geometry, required to crush(that's what comminute is) things into smaller and smaller particles. think of it this way, it is easy to break a rock into two pieces with a hammer, but to powder it, you would have to hit it thousands of times, and at a certain point, you would not be able to crush it into smaller pieces, because it would just move out of the way through teeny tiny momentum transfers. a ball mill is used to crush things into fine powder, because that is the ultimate geometry for crushing, ...two opposing arcs.
so, in short, the two towers fell way too fast, and the third should not have fallen at all.
to the OP, tell your friends to watch the youtube videos of mystery workers at wtc7 telling people to get back because the building is 'going to BLOW UP'.
talk about foreknowledge. where were the debunkers on 911 to tell these workers that the building was going to 'collapse naturally', and not 'blow-up' after a countdown.
tell them that silverstein could not have been talking about firefighters when he said 'pull it', because there were no firefighters in the building.
tell them all of the exterior columns failed at exactly the same rate, which coincidentally exactly matched the acceleration due to gravity, ie. freefall. tell them also that these columns failed from the bottom up, and that because they failed at the rate of gravity, it took exactly zero energy to break them.

There is no need to go any further. The assertion that the buildings fell at free fall speed is incorrect.
I posted a direct quote from the NIST report and they agree that it was 'near freefall speeds.
Your original assertion concerned "free fall" speeds, not the amount of energy required to initiate a global collapse.

The government and the vast majority of the population is not questioning the results from NIST. Thats why the government isn't do anything. They are not interested in a silencing a small, yet loud group.
Yes I agree the rest of the free world is just that.
And I would have to disagree with the "twoofers trying". All the truth movement has done has made accusations of bombs, therm*te, and space beams.
They have applied the scientific method where the government has applied pseudoscience
But one thing I knwo for sure will never happen, is the calcs on how much explosives would be needed.... and then time matching that to videos cuz that would be debunking his little "thesis".
All in all, just a sad display of affirming the consequent fallacy.....

LabTop's work on this is excellent and extensive and it indicates a definite 'something' but whatever it is doesn't stand out visually or audibly for the level of force it would take to produce that signal.
Obviously the part I have bolded is false. If nothing was there to account for it, then why is it on the seismic record?
What's apparently wrong is your assumption that HEs or some other conventional blast put the energy to the bedrock. It is possible for something you don't know about, to function, unless you already understand everything that functions. And then we would have to be dealing with the impossible. The signal was still presented on the chart, as actually occurring.
