I know this seems like a really weird topic, but I started thinking about it on the way to school while listening to Toby Kieth's Courtesy of the Red, White, and Blue. Say 9/11 carried out the same way that it had, except the fires in the buildings eventually burned out instead of causing the towers to collapse. What would we have done with the buildings? Would we have had to demolish them manually (please no "they were demolished manually. 9/11 was an inside job!")? Would it have even been possible to repair such extensive damage so high up? I know nothing about architecture and/construction and am genuinely curious about this.
