Spy ship Hoyt S. Vandenberg: An experienced demo team must use a novel explosives system to scuttle their first ship - the Hoyt S. Vandenberg. In this unprecedented demo job, Controlled Demolition Incorporated teams up with a marine salvage crew to turn a 17,000-ton former spy ship into the second-largest artificial reef in the world. Using torches above the water line and high explosives below, the team sinks a colossal 17,000 ton former spy ship to create an artificial reef.
