What goes up must come down.
Interesting article from the post 1973.
I used to work for Monash Uni, and I was talking one day to a structural engineer and architect professor. We got on to the case of how in the hell were they going to dismantle all these skyscrapers. He stated that nobody knew as yet! But he was certain that it was going to cost almost as much to take them down as it was to put them up. And that most of the sky scrapers were going to have a 50 year life span.
Its interesting that the WTC being knocked down by two planes has not only saved the buildings owners several billions of dollars in future demolition costs, but also delivered a $10 billion dollar insurance windfall to them.
Hmmm....
