What other factor collaborated then, please enlightin us, please.
And what about building 7, did a plain hit too? Oh no, it was debris from the twin towers, should I bring the video up too to show you how it came down? The 9/11 report to this day doesn't have an official explanation, but they think it came down due to OFFICE FIRES. And what about the adjacent buildings, how come they did not come down on their own foot print on the same day as the twin towers and building 7? Do you have any proof that the buildings surrounding the twin tower came down on their own foot print as well? Please show, please. Did those buildings did not catch on fire? How do you know? Is there official report stating otherwise?
You probably think you are winning this debate as well, that your argument as so astute, well written with such brilliant gramar that you must think I'm cowarding to such level of intellectual nonsense, with commom sense evidence showing the contrary.
