The implosion of the Humana building at Second and Main happened just as planned Saturday morning, as the building disappeared into a cloud of dust just a few moments after 7 a.m.

The building was surrounded by downtown structures, and police enforced a "keep out" zone around the area.

The city parking garage at First and Main was a public viewing area.  Guests at the Galt House also viewed the event.
