Has the United States ever accidentally lost a nuclear weapon?
Yes. Experts estimate that at least 11 have been lost. For example, in 1958 a damaged U.S. bomber was ordered to drop a nuclear weapon into the Atlantic before landing. It was never recovered and rests somewhere off the coast of Savannah, Georgia. (For more information, see the Center for Defense Information, http://www.cdi.org/Issues/NukeAccidents/accidents.
