Remember the time the US Air Force accidentally dropped a nuclear bomb on a family in South Carolina? That and 31 other nuclear accidents including: nuclear bombs inadvertently falling through bomb bay doors; the accidental firing of a retrorocket on an ICBM; the vast dispersal of radioactive debris; and the loss of enriched fissile material and nuclear bombs (which are 'still out there somewhere').
