Perhaps a building as large as this in the middle of downtown cannot be subjected to explosive demolition, but many other very large structures are, nowadays. Stadiums, for example. The method produces much less mess than the WTC towers did for two reasons, mainly: 1. Toxic and dangerous materials are removed from the buildings beforehand. These include things like fluorescent light bulbs. When you pulverize a million of them it causes a lot of pollution. 2. They have sophisticated dust control. They sometimes build a temporary plastic structure around the site where the building will fall, and they spray water before and after the event to keep the dust down. There is some danger in doing this, but they pick a time when no one is around, such as early Sunday morning in a business district. They are very careful and the method usually works well, saving lots of energy, time and money. - Jed
