You've done well! A very well documented investigative piece, @steemit. Some additional points that I didn't notice, that you may cover in later pieces, is the owners of the building, Larry Silverstein, and Frank Lowy. Frank runs Westfield Shopping centres, and associated corporations, and has two sons, Peter, and David. You probably know about them taking out two insurance policies prior to the event, both covering damage from terrorism, and the building requiring an expensive refurbishment, because it had a lot of asbestos in the structure. However, there is some additional info that ties this to another event in Australia. Our Prime Minister at the time, John Howard, happened to be in New York on that day, coincidentally. Now, at a guess, I'd say he made the grade for a front row seat, because he was instrumental in setting up, and executing, the Port Arthur massacre in Tasmania. It also gave him a personal perspective that helped explain why he jumped onto the terrorism bandwagon so readily, limiting personal freedoms even more, after taking away the guns of lawful owners. There is much more to be told about that event, but that's enough for now. I don't know where you live, but if it's in the US, they're heading that way as well.
