The ICBM, or Intercontinental Ballistic Missile, is a nuclear weapon designed to destroy entire cities. Fortunately, they have never before been used in war.
They have, however, been tested.
This particular ICBM, a Minuteman, was dropped by a C-5A Galaxy aircraft over the Pacific on October 24, 1974. The Minuteman weighed 86,000 pounds and fell from a height of 20,000 feet. The missile’s rocket engine fired at 8,000 feet.
