My take on these documetaries is that they seem to be very convincing because they cite supposed scientific facts and data and make claims about what is and what is not impossible that the average layman not knowing anything about the subjects takes as being accurate.

For example the In Plane Sight video, immediately after watching that I felt sick to my stomach as I could not see how a plane could have possibly crashed into that building.

The crash site shole was just too small and it seemed it must have been a missile.

Half an hour later after reading rebuttal's on another site my mind was put to rest as I could now see that a plane actually isn't as wide as it's wingspan but rather just the width of the tubular middle part of the plane as the wings would have come off on impact and only the cyclindrical middle part of the plane would have buried into the Pentagon.

What I then found even more absurd and comical though was that after a bit more searching I found (seriously) conspiracy theorists claiming that the Loose Change style theorists, the Pod People they are called, are actullay themselves a government sponsered agency setup to create a diversion to camaflauge the true fact that the Jews did it!

Ultimately you have to remember that conspiracy theories, like any form of book and dvd release are about entertainment and selling a product.

Just have a look at the websites that are selling these films, books and countless other conspiracy theories. It's their industry, how they make money and as such they will ALWAYS produce conspiracy theory alternatives to any major event simply because they sell. That is the bottom line, even Michael Moore is guilty of the same thing.

Remember EVERY industry IS an industry meaning it exists to make money. The conspiricay theorists are no different.
