Overview: The fixed service structure is each pad's most prominent feature, standing 347 feet from ground level to the tip of the lightning mast. The lightning mast itself, 80 feet tall and made of fiberglass, supports a one-inch stainless steel cable that starts from an anchor 1,100 feet south of the fixed structure, angles up and over the mast, and then extends back down to a second anchor the same distance north. Below the lightning mast is a hammerhead crane used for pad hoisting operations.
