BBC’s “The Conspiracy Files” investigative report on the collapse of WTC 7 will air on Sunday, July 6. They have some promotional videos on the web, including an explanation of their reporter’s statement that WTC 7 had collapsed before it did.

The conspiracy theorists claim that it had to be a controlled demolition, because WTC 7 was not hit by a plane and was virtually untouched. But the latter claim is false–WTC 7 was heavily damaged by the collapse of the twin towers, with a giant hole in the southwest corner about 20 stories high. There were raging fires in a building full of diesel fuel and backup generators.

The BBC investigation will no doubt report in more detail on the facts that the conspiracy theorists like to pretend don’t exist.
