 Though a debt of $206 million remained on the structure, the Seattle Kingdome was demolished by "implosion" on a cheery Sunday morning in March 2000. Over 50,000 tons of concrete and steel came crashing down causing the equivalent of a magnitude 2.3 earthquake. "SOS" documents that morning thru time lapse photography and other experimental film techniques. The destruction was the result of Referendum 48, a ballot initiative backed by $5 million in advertising (the most expensive ballot initiative campaign in WA state history.) The theme for this ad campaign was "Save Our Seahawks" from which came the name for the film.
