The Center and East Towers are made of hollow tubes bolted together. Unfortunately, water can get inside the tubes, expand when frozen, and burst the pipes, undermining their structural integrity. (see the photo in the upper left) We have begun a fundraising campaign to replace the braces of both towers. We have found a source for replacements which are solid, galvanized steel, painted in the FAA colors at the factory. This will save over half of the cost of replacing the existing towers and they will NOT have to be taken down. Praise God for this amazing revelation.
