On a rainy sunday morning this 20+ story building was brought down. Many folks including myself were caught somewhat offguard by the first blast. The start time for the implosion was move up roughly 10 minutes because of the threat of a heavy downpour. With that change I didn't get to film a lead in. This video starts with the building in motion. You may enjoy this Youtube version from a different angle, "coolest building implosion"
