Things have taken an interesting turn. Map updated as I have time between digs. Most notable new entry is that the architect of the Irwin Library at Butler University was the architect of the WTC towers and buildings 4, 5, and 6. Meanwhile, Lee Hamilton, was appointed by GWB to be the Vice Chairman of the 9/11 Commission.
Anyone can take this map as a starting point for digs on whatever suits your fancy. Personally, I am trying to find out more about J. Irwin Miller, the Irwin-Miller-Sweeney cabal.
