Workers tackle dismantling "Slick-4." Space Launch Complex 4-East on Vandenberg Air Force Base was the site of 68 launches from 1964 to 2005. One of Vandenberg Air Force Base's most fabled landmarks -- an aerospace icon with a Cold War history -- is quickly disappearing from the skyline of the classified military base. The almost half-century old Space Launch Complex 4-East, a gigantic tower on the southwest coast of Vandenberg and easily visible from throughout the Lompoc Valley, is rapidly being removed to make way for Space Exploration Technology's new Falcon Heavy, a 22-story-tall booster considered the world's most powerful private rocket.
