The image of the 1972 demolition of Pruitt-Igoe public housing complex in St. Louis occurred to me on Sept. 11, as I listened to the radio broadcast from New York and the live feed of someone narrating the collapse of the first tower. That image constellation has been lurking ever since but I haven't heard anyone else mention it.
So today I remembered and did a google search on Pruitt-Igoe and World Trade Center. Whoooaaa! Try it yourself, urban design wonks.
