You know the basics of essays is to give footnotes in references. How can you actually believe that crap without them providing sources? An email dated 3 years later doesn't count. If there was indeed a power shutdown, there would be an internal communications email stating the reasons why. Not to mention it would be collaborated by others as well.

Out of all the employees that worked in WTC, only 1 came forward about this....3 years later. Hilarious.
