^ Conspiracy theory dude: do you have a degree in structural engineering? Do you, in fact, have any knowledge of structural engineering or skyscraper construction? If not, why do you think you're qualified to judge contrary to the professional opinions of people who do?
EDIT: Such as the professors etc. who disagree with the main academic paper that conspiracy theorists use to back up their claims? Webpage here.
EDIT 2: Relevant information related to structural engineering on Wikipedia.
