A Titan I launch sequence is demonstrated at Vandenberg Air Force Base, California, in 1961. Fifty-four of these liquid-fueled missiles, each carrying a 4.5 megaton warhead, were deployed in groups of three at five air force bases between 1962 and 1965. Each missile was 98 feet (22.9 meters) tall. The elapsed time between the first and last frame is approximately 15 minutes. Note the persons in the first and last frames.
