It is VERY important to READ ALL of this information, until you UNDERSTAND it. It is not difficult. It is mostly common sense and simple "one plus one equals two".
Comments on another site about this video have convinced me that the text information accompanying my video has NOT been read by all viewers. Therefore the video is consistently misinterpreted.
SO READ the information PLEASE.
If you don't read it carefully, you probably WON'T BE ABLE TO UNDERSTAND WHY this video shows proof.
If you HAVEN'T read it, please don't write a comment. It will surely miss the point.

The flying black material shown in the clips is generically called "geotextile". In his book "Demolition Experts: Life Blowing Things Up", Mark Beyer writes: "Next, demolition experts wrap each post with chain-link fencing to control large chunks of debris. Finally, each post is wrapped in geotextile fabric to restrain small rocks from flying outside the building.
"Because linear shaped charges do not create much flying debris, H-beams often have a simple plywood box strapped around them. Demolition experts wrap geotextile fabric around the plywood box as an added protection."
(source: Google Books search)
In the series "The Detonators", examples of both processes can be seen:
DYNAMITE or sometimes bundled DET CORD is used to explode columns made of concrete with interior steel reinforcing bar.
LINEAR SHAPE CHARGES are used to cut H-beams, box beams, I-beams, or steel plate. A shaped charge works very differently from dynamite or det cord. It creates an extremely high velocity, extremely high pressure jet of incandescent copper in vapor or "plasma" form. This moves at about five miles per second, which speed could take it to the moon and back by tomorrow afternoon, that is how fast it is.
Shaped charges would have been the ones used for the core columns, since the Twn towers had structural steel frames, not steel-reinforced concrete frames. There is a world of difference between the two types, so they require different demolition solutions.
The flying thing in question is its geotextile wrap. The same material can be seen in numerous commercial demolition videos and photographs. It looks like a black doormat or one of those rubber fatigue mats.
The demolition guys on "The Detonators" call it "Geotech" or "Geotex".

Here is an explanation of this video. (December 4 2012)
1. The opening scene (as well as the part at the end) comes from one of the archival NIST FOIA 9/11 videos. It can also be seen at /watch?v=oTx20dzVMtE .It shows an ejection of air, or air, smoke, dust, and debris. The thing to notice happens quickly. Look for the black object being ejected. This object has been the source of some confusion. It has been theorized that it is a piece of clothing or even a body. It is neither.
2. The center of the video shows some scenes from videos made by CDI, Inc., of known, acknowledged demolitions- the first of an apartment building, and the second of a bridge. In the clips of the demolition of the apartment building, numerous black objects remarkably similar in both appearance and behavior to the black object seen at the beginning (and end) of this video can be seen at the forefront of the demolition "squibs".
In the bridge demolition video, it can be seen that the demolition charges are wrapped in some black material, which goes flying when the explosive is triggered. If A is the black object seen in the beginning, and B represents the black objects seen in the apartment demolition, and C represents the flying black pieces which wrap the explosive charges on the bridge, it is not at all difficult to see that, in all likelihood, A= B= C. CDI, Inc. was hired for the 9/11 cleanup job. It should be noted that CDI is a demolition company, not a debris cleanup company, although cleanup is part of their own demolition jobs.
If you can't understand what this video shows, watch it again until you do, and THEN comment, if you wish. Hostile and purposely ignorant comments will probably be removed. Thoughtful responses will be kept. Thank you for watching.
