00:00 Accidents with nuclear weapons have occurred throughout history, prompting the U.S. military to create a code word for such events.

02:12 The protocols surrounding nuclear weapons were developed due to embarrassing and dangerous accidents, with the first recorded incident occurring in 1950 involving a Convair B-36B bomber carrying a Mark IV nuclear weapon.

03:44 A bomber carrying a nuclear bomb had to be abandoned due to engine failures caused by extreme cold weather, and the bomb was detonated without its plutonium core, but the bomb and the enriched uranium inside were never recovered.

05:19 A fully functioning nuclear weapon with a plutonium core was accidentally dropped into the water off the coast of Tybee Island, South Carolina, and was never recovered.

06:53 In 1961, a B-52 plane carrying two Mark 39 nuclear bombs crashed, with one bomb landing safely and the other disintegrating upon impact, revealing that three of the four safety mechanisms didn't deploy.

08:30 A B-43 nuclear bomb with an active plutonium core was lost when a Douglas A4E Skyhawk carrying the bomb rolled over the side of the USS Ticonderoga aircraft carrier and sank to the bottom of the ocean, while in another incident, a B-52 bomber collided with a KC-135 tanker, resulting in the detonation of two hydrogen bombs and the recovery of one bomb by fishermen who claimed salvage rights.

10:10 Broken-arrow incidents, although decreasing in number, have occurred more frequently than we know, with the Soviet Union likely having many incidents that were never reported, and while the risk of such incidents has decreased, it can never be completely eliminated.
