While the nuclear devices that fell near Goldsboro were equipped with safety devices to prevent accidental explosions, much as revolvers have safety catches, Jones reported that three of the four safety mechanisms in the bomb that had deployed its parachute had become unlocked during its plunge to the ground. Two were rendered ineffective by the breakup of the aircraft, and a third was set off by the fall. Fortunately, the last failsafe, a low-voltage switch, worked. According to the Guardian, “When the bomb hit the ground, a firing signal was sent to the nuclear core of the device, and it was only that final, highly vulnerable switch that averted calamity.”“One simple, dynamo-technology, low voltage switch stood between the United States and a major catastrophe,” Jones wrote. The safety supervisor also asserted that had the mid-air breakup of the B-52 caused an electrical short to the switch, “a postulate that seems credible,” it could have resulted in a nuclear explosion. Jones concluded that “The Mk 39 Mod 2 bomb did not possess adequate safety for the airborne alert role in the B-52” and that the devices designed to prevent an accidental detonation were “not complex enough.” The near-disaster resulted in more stringent safeguards being placed on America’s nuclear arsenal.
