What a target for some future wacko.. Perverted meglomanical dreams are made of stuff like this..
Let's hope that some American spirit is revitalized and we can once again build the skyscrapers we are capable of. We should have dozens of skyscrapers over a mile high by now and within 25 years, we ought to have skyscrapers topping 10,000 feet - with several of them joining each other in some of our bigger cities to literally form "cities in the sky."
There was a science fiction story I read some time ago that talked about such a city in the future. There were so many skyscrapers linked to each other that people lived their entire lives above street level, never having a need to come down to the lobby. The roofs of these buildings were covered with parks and gardens and there were even professional sporting events going on up there.
