		The nuclear weapon was completely destroyed in the detonation which occurred approximately 4.5 miles south of the Kirtland control tower and 0.3 miles west of the Sandia Base reservation, creating a blast crater approximately 25 feet in diameter and 12 feet deep.
		Following the accident, Air Force crews were ordered to "lock in" their nuclear bombs, which reduced the possibility of accidental drops but increased the danger during a plane crash.
		The nuclear weapons were being transported in a tactical ferry configuration, meaning that no mechanical or electrical connections had been made from the bombs to the aircraft.

		Aging of nuclear reactors, in particular the effect of prolonged operation on materials and large components, is endemic throughout the world's nuclear industry.
		In addition to the risk of accident, nuclear plants are highly vulnerable to deliberate acts of sabotage and terrorist attack.

	Nuclear and radiation accidents - Wikipedia, the free encyclopedia
		An example of nuclear accident might be one in which a reactor core is damaged such as Three Mile Island, while an example of a radiation accident might be some event such as a radiography accident where a worker drops the source into a river.
		Decay heat accidents are where the heat generated by the radioactive decay causes harm.
		A related cause of accidents is failure of control software, as in the cases involving the Therac-25 medical radiotherapy equipment: the elimination of a hardware safety interlock in a new design model exposed a previously undetected bug in the control software, which could lead to patients receiving massive overdoses under a specific set of conditions.

		Many of the new crew for the nuclear submarines had received only six months training, training that often was insufficient or irrelevant to the situations they might confront on a nuclear submarine.[608] There was a widespread irresponsible attitude from incompetent outside specialists.

		CDI on the other hand uses fairly inflammatory language to imply that the DoD/DoE statement is false and misleading, citing Daniel Ellsberg's discoveryi of documents that quote physicist Ralph E. Lapp as indicating the weapon in a January 1961 accident accident was only one safety switch away from (implied nuclear) detonation.

	Nuclear accidents and incidents
		But when dealing with nuclear power, the scale of accidents and incidents is far wider and more dangerous than with other energy sources, and affect not only current generations, but those to come.
		The worst nuclear accident on record is the Chernobyl explosion of 1986, from which Belorussia, Russia and Ukraine are still reeling (Photo shows the Chernobyl Shelter today).
		Aside from these industrial accidents are always military accidents, like the sinking of Russia’s Kursk in 2000, the sinking of Russia’s K-159, and a number of US submarines running aground or sinking, like the 2005 incidents off of Italy and Guam.
