I saw a documentary that made the case that the Twin Towers' design was compromised from the beginning. The original design called for pillars at the corners, but the designers wanted open floor plans, so the city could be seen from anywhere in the offices. (Makes me wonder if the terrorists did more research than we would think)

I'm sure there are some civil engineers in here who would just love to weigh in so now I wait. :)
