I just watched it and took some notes. Wow! I feel both enlightened and completely vindicated.
I've taken some notes, and I'll watch it again. I think this is worth a thread of its own and I'll leave my thoughts for then. But thank you, @benthamitemetric. Thank you very much. Great find!“In the past, no one would have ever thought that … the failure of a single connection could bring down a 47-story building. Today, we actually do believe that that might be possible. A very important technical lesson that we’ve learned through the World Trade Center.” (45:00)
That kind of ties into a question I wondered about earlier in the thread... That if before 9/11, you gave someone like CDI the task of demolishing WTC 7, could they have figured out they only needed to blow up column 79?
Although even if they could have figured it out, they probably wouldn't have done it like that. In controlled demolitions, you want to ensure the building comes down, without leaving it to chance. So you would much rather go for overkill rather than trying to figure out the minimum amount of charges required.
