The Minuteman is a land-based intercontinental ballistic missile first flown in 1961, and over 400 will remain in service until at least 2030. It was the first solid-fuel missile to have a digital flight control computer, a combination that enabled short-notice launch. On 24 October 1974, a C-5A Galaxy successfully carried out an Air Mobile Feasibility Test when an 86,000-pound intercontinental ballistic missile was extracted by parachute from the aircraft while flying at 20,000 feet over the Pacific Ocean. After the missile stabilized, its rocket engine fired, and the 10-second burn allowed it to climb 12,000 feet before it dropped into the ocean as planned. Although this was done only once, it was sufficient to serve as a negotiating point in the Strategic Arms Limitation Talks.
