It took 20 seconds and 250 pounds of explosives to bring down the 45-year-old structure at 7:36 a.m.
Before 1996, the building housed 165 members of the U.S. Coast Guard and their families. Officials will put a softball field — part of a new 30-acre park under construction on the island — in its place.
The implosion has been planned very carefully. The building has been packed with explosives on 3 levels. So it could pancake on itself.
