Will 9/11 conspiracy theories ever stop ?

I'm terribly sorry for resurrecting an old thread, as I didn't know where to put this, however I just saw this and thought some people might be interested in the findings on WTC Building 7.  A documentary-series has been made and will begin airing on PBS apparently (I do not have this channel in Australia so I'm not familiar with it).   The Youtube link is a 2 min trailer.  There is also this link which gives more information if you are interested in reading more.   

OK, my first area of concern is: "In addition to the university and its personnel, we would like thank Architects & Engineers for 9/11 Truth (AE911Truth) for providing the funding to conduct this research."  

I thought this might be fun:

Most of the 9/11 commissioners (the people who wrote the report) claim there was a cover-up amongst other things. 

Yes, but WHAT cover-up? I can believe there was an effort to hide Saudi involvement. I don't believe the whole thing was a government conspiracy.

Just read the PNAC document and that alone will tell you the truth. Btw, I don't think any of the said "terrorists" boarded the planes. The terrorists were sitting in a bunker watching the show.   

To be fair, there is the issue of the Carlisle Group.  This is a body of Oil Industry Investors and heavyweights that includes the Gottis, the Bin Ladens, and the Bushes.  The Carlisle Group was trying to negotiate an oil pipeline to carry oil from central asia thru Afghanistan to Pakistan's ports.  The Taliban had made that impossible by demanding too high a tax on it.  Suffice to say, that due to the long period of regional instability, the pipeline has never been laid, but it was certainly reconsidered when the USA put boots on the ground in Afghanistan as a result of 9/11.  I see her...

You can hear a second explosion in Washington in this video.  Does anyone know what caused it?  The media quickly jumped on it and misreported this second explosion as a car bomb outside the State department, and other news channels thought it was an explosion on Capitol hill.  What was this sound?   16:59    

Pardon my ignorance, but where was this footage recorded (as in, I assume it was somewhere in Washington, but where in relation to the Pentagon?), and what time was it recorded. My computer's sound output is misbehaving so I can't hear the sound. But I notice a lot of people are looking up. Is it possible the sound was a sonic boom from a fighter plane overhead?

I haven't looked at the footage but is it possible the purported 'second explosion' might be a reflection off of the buildings?
