With cracks as sharp as the frozen Arctic air, a 1,357-ft steel communications tower in Port Clarence, Alaska, tumbled to the ground on April 28, the first step in the U.S. Coast Guard�s decommissioning of its network of LORAN radio navigation facilities across the country.
The 400-ton, 45-segment triangular steel tower is the largest man-made structure to be felled by explosives, according to Controlled Demolition Inc. (CDI), Phoenix, Md., which performed the operation as a subcontractor to Jacobs Field Services North America.
