My friend L. has just emailed me this video, which I new about, but which I do want to post here for those of you who say that they are not engineers and that they have a hard time coming to a conclusion about what happened with WTC7. In this video David Chandler, a high-school physics teacher, uses basic (high-school level) yet absolutely incontrovertible laws of physics to prove tat WTC7 did fall at free-fall acceleration for a significant part of its collapse.
For those of you who, like myself, were getting bad grades in physics in high-school, let me begin by some very simple reminders:
a) “free fall” is not a speed, but the *acceleration* of a body pulled down by earth’s gravity when it encounters no resistance at all.
b) if a body encounters even minimal resistance it will slow down and not fall at free fall accelerations. For example, if you drop a bowling call though a few glass windows stacked up horizontally on top of each other, it will look like the bowling ball just smashed through without slowing down but this is an illusion. If you carefully measure the fall of the bowling ball at each point of its descent you will detect a slight change in motion each time the ball hits a glass window. What happens is that some of the (so-called “potential”) energy of the ball is used to actually smash through the glass, thereby slightly slowing down the ball. Conversely, and this is important, if you detect no such slowing down, that means that no resistance was encountered by the ball on its descent and that means that somebody or something already smashed the glass windows before the ball passed through that section of space.
Now take a look at Chandler’s video:
What Chandler is proving here is that for a substantial part of its collapse the top of WTC7 was falling at an acceleration which is so close to the earth’s natural acceleration (9.81 m/s2) that we can say with total confidence that it encountered no resistance or, if you prefer, that the weight (potential energy) of the top portion of the building was *not* used to smash through the lower floors simply because by the time the collapse began these floors had already been removed.
How can somebody remove entire floors of a large building a) simultaneously b) symmetrically and c) instantaneously ?
There is only one way to do that: explosives.
QED.
The Saker
I remembered reading an article about this scenario last yr but couldn’t locate it . In lieu I found this site which talked about the conclusion reached by Chandler: explosives being used :

Well now, to anybody of good will, we can show free fall for – what 2.8seconds. How with the same kind of lead pipe in the head certainty, we need to show that free fall is not compatible with any sort of asymmetrical building damage or fire. I debate with people about this and they say there exist pictures of one corner of bulding 7 missing due to some sort of debris from wtc1 and wtc2. Every stupid ah hoc argument from the “nothing here- move right along” crowd seems to pop up in an endless sequence. Same kind of crap about one detail or the other about the Holocaust or any sanctioned national myth. It’s impossible to swat them all down and declare victory. The “it’s a free media- certainly somebody would have spoken out if you are not a kook” bunch seems to prevail in the public mind, because if you control the rules and limits of questioning, it seems to be the ball game. This observation is the gateway to tyranny. The jury is still out on whether a hand full of internet sites with 0 capitalizations can make any difference or not. Google can help or hurt. IF they rank searches on WTC-7 free fall. In some order that exposes the world to the voice of David Chandler, or Gage, or you. – or not- seems important, but maybe enough people (like my Wife) don’t care enough to google that anyway. You can’t get a fair picture of the world from inside your own little world looking out.
People don’t know there are countries where Gage gets on TV and radio, and people get to read about him in the paper and respond in a letters to the editor section. Not Here. It’s like expecting a politically charged discussion in Pravda in the old days. I guess it was not a free media, – but relatively inexpensive given the stakes, and it was purchased by people powerfully motivated with an agenda and deep pockets.
I am very sad that Buchanan as come out so forcefully that Obama should command that Preacher to not burn the Koran. In a “country at war” , which is I guess, the US from here on, we have suspended the first amendment. If people are interested in not putting the troops in danger because of a Koran burning, hows about bringing them all home?
Maybe – just maybe, voices like yours can continue to swat down the next argument in the inevitable sequence regarding WTC-7 until no conclusion is left but confronting the awful truth. The free fall part was exposed by some simple physics, given where you are standing, and the size of the tower is established, one can measure the acceleration of the tower crash and determine it is close to 9.8 M/sec^2 free fall. (with very very few easily verified assumptions) The next argument, which seems obvious to people with any sense, is that this is 100 percent incompatible with fire, or even if some corner of wtc-7 was missing. Those photos that show this missing corner. ( I have seen them and so have you probably) – are they photoshoped- and even if genuine, can they explain a free fall total building failure mode?
These are not clean like the free fall argument. Maybe this is the next frontier in this thing. Once people are forced to admit the role of explosives, their eyes may open. I saw one discussion on TV where some MSM fellow got some government official to speculate that there were Government pre planted explosives in WTC-7 for contingency reasons and the MSM guy seemed to swallow that without taking the logical step, he hardly blinked and offered not follow up questions. No matter what is demonstrated, “THEY” will never kneel in the medial. No matter how preposterous their cover story becomes, they will present it, and joe idiot in the street seems willing to buy it.

This observation is the gateway to tyranny. I was recently in Talin Estonia on a trip, and spoke to a tour guide who remembers the media manipulation pre 1990. The wall was there of course to protect the noble soviet states from the capitalism of the west. – most people accepted if not believed it, because the social (and legal too) penalty for being vocal in these matters was severe. A search for truth was never really the issue. The jury is still out on whether a hand full of internet sites with 0 capitalization can make any difference or not.
@oldman: we need to show that free fall is not compatible with any sort of asymmetrical building damage or fire. I debate with people about this and they say there exist pictures of one corner of bulding 7 missing due to some sort of debris from wtc1 and wtc2.
If I recall correctly, NIST estimates that about 25% of the north face of WTC7 has suffered from debris falling down from WTC1. We also know that the damage was highly ASYMMETRICAL since WTC7 was hit only on one side. How do we THEN get a symmetrical fall? Again, the facts are now out, its just that people don’t wanna hear about them.
If people are interested in not putting the troops in danger because of a Koran burning, hows about bringing them all home?
Yes, the hypocrisy of that all is amazing…
The funny thing is I think they stuffed up their efforts as for wtc7 to fall they must have expected some part of the twin towers to knock on to wtc7.
If anything the collapse was too clean, a mistake I guess they’ll make sure doesn’t happen next time.
