Broken Arrow Nuclear Weapon Accidents

Has the United States or any other country ever had a plane carrying a nuclear bomb crash?  Has a nuclear  	weapon ever been lost?- question from Sandy Joulkowski 
Accidents involving nuclear weapons have occurred almost since such devices were first developed, and these events  were a common occurrence during the Cold War.  However, the US and other countries possessing nuclear arms  developed various safety systems to prevent accidental thermonuclear reactions within these weapons even under the  most extreme circumstances in order to avoid potential catastrophes.  Even so, non-thermonuclear detonations of the  conventional high explosives carried within nuclear weapons still pose a serious threat since they can spread  dangerous radioactive contamination much like a so-called “dirty bomb.”  This scenario has occurred several times  during aircraft accidents when high speed impacts or burning fuel caused the high explosive charges on nuclear  weapons to ignite.
At least three dozen serious accidents and incidents involving atomic or nuclear weapons have occurred since 1950.   Many of these cases cost the lives of military personnel, led to the release of radioactive material, or resulted  in the loss of the weapon itself.  Most of these weapons fell into the ocean where the nuclear material could not  be recovered given the limits of current technology.  It is estimated that over 50 nuclear warheads have been lost  in the world’s oceans following aircraft or naval accidents.  Another 26 nuclear reactors from ships and submarines  have also been lost or deliberately dumped at sea.
