Monkey wrench to launch missile not included.
(Woops! Wrong missile system -- this refers to an unfortunate accident at a Titan II ICBM silo (374-7) in Arkansas twenty years ago. One of the technicians dropped a monkey wrench (actually a socket wrench) down the silo, striking the missile and piercing the fuel tank; when pressure was lost in the tank the missile collapsed and exploded. The 700-ton silo door was recovered a short distance away, and the warhead was tossed in another direction but because of the many safeguards did not go off.)
Most ICBM missile silos were intentionally blown up as part of the START arms control treaty. Still 550 of 'em 'prairie submarines' out in the Great Plains, though.
