This is an excellent documentary for all levels of viewers from beginners to professionals who are interested in what happened at the World Trade Center on 9/11. The documentary includes interviews and explanations by many building professionals and others using simple language to explain how the buildings were constructed, and more importantly, how they were destroyed. The speakers apply simple concepts from physics to clearly show that the official story of aircraft impact, followed by fire, followed by a gravity-only destruction of the entire structure of both twin towers, down into their basements, could not be true.
The producers are to be commended on putting together such a tapestry of facts and explanations that can serve as a backdrop to understanding the events of that day. I have the original boxed set and the bonus DVD material which includes additional interviews is worth viewing for more in-depth descriptions of the events and the experts' stories about why they are speaking up. You can watch the documentary here ... then you can ask your local public library for a copy so that you can see the additional Bonus materials.
