I still remember when they imploded the old Kingdome Stadium in March 2000. We had front row seats downtown at The Harbor Club and witnessed the perfectly-timed demolition of Seattle's old Mariners' Stadium to make room for the new Safeco Stadium. Although it went down perfectly, it still left a lot of dust and debris all over the downtown area for months.
I was just reading about a new approach to demolition in Japan: They take it out one floor at a time... starting from the bottom up!
